Automatic Chicken Feeder

Our project, the automatic chicken feeder, can be used for easier and more efficient chicken feeding. It will make the twice a day feeding as simple as pressing a button. We wanted to do this project because one of us is taking home four of the chickens we raised at school. He wanted to make his chicken related chores easier and less time consuming.

There were some challenges that we faced. The challenge that we faced the most was that the motor was not strong enough, or the containers movement was not stable. The motor we used was not strong enough to lift all the food, so we had to put it at a slant to distribute the weight across the feeder. The container was originally designed to push up the food and then it would fall out a hole, but when the container was pushed up, the container would fall over. We scrapped that idea and went with a wheel that would push out the food, and it was more feasible than the last idea.In the process of doing this project, we learned that dc motors are not the strongest and we needed to not put all the weight on the motor, or else it would not work.

Our next steps would be to build the feeder with plywood and nails, instead of cardboard, duct tape, and hot glue, and replace the DC motor with a stronger one. If someone else is going to build this, I would recommend them to use a more powerful motor than a DC motor.The cost was estimated to be about $16.50. This includes plywood for structure, the DC motor for the automatic part, a couple thin steel rods that can be used as axles. On the Paper Mech website, we found a simple machine to push up and down a platform, but that idea was eventually scrapped due to the platform not being stable. http://www.papermech.net/up-down-crank/

The Useless Box

We made a Useless Box out of foam board, wood, and a circuit. As the name suggests, it literally does nothing. You flip the switch at the top of the box and a wooden arm will come out of the box to flip it back. Its sole "purpose" is to turn itself off. Our objective was to create a useless object that people enjoy using.


First, we had to gather the materials. It was challenging to find them, and we ended up ordering some of them in bulk on Amazon. We then cut the arm and the faces of the box out of foam poster board using X-Acto knives. We ended up replacing the top of the box and the arm with wooden pieces, because the top needed to withstand the lever being flipped up and down, and the arm needed to be heavy enough to flip the switch. After this, we connected the toggle switch, lever switch, battery pack, and motor to create the circuit. We then hot glued the bottom and all of the sides of the box but one. We assembled the circuit inside the box, then finally glued down the top and remaining side.


After browsing the internet for Maker Faire ideas, we came across a wind-powered machine called the Strandbeest. We were amazed at the Strandbeest, but, though the prospect of creating one was exciting, we decided that it was too complex to complete in the time limit we had. We continued to search and eventually found a kit to make a useless box. We researched the useless box and were immediately intrigued. We thought that creating a machine with no real "purpose" was hilarious. We settled on making a useless box but decided to increase the difficulty of the project by creating it from scratch and rather than using the kit with premade pieces.








During the process of constructing the useless box, we came across many challenges and were forced to tweak our design in order to overcome obstacles. Ensuring that the wooden arm successfully pushed the switch was one of the main issues we had. We had initially cut an arm out of a sheet of foam board. However, after cutting it out, we quickly realized that the foam was too light and weak and wouldn’t be able to push the switch. The foam arm was flimsy and relatively “soft.” Due to this, we decided to make a new arm out of wood. The wooden arm was significantly more durable and rigid than the foam board iteration, and it was able to push the switch. The one downside of using wood was that altering the size of the arm was more difficult. At one point, we had to saw off a bit of the arm in order for it to hit the switch at the right point. While sawing the arm, the wood broke. We had to glue the pieces back together and let the adhesive dry. This set our entire construction process back a day.





In the process of making the box, we learned several things. One thing we learned was how to use a drill. One of our group members sort of knew how to use a drill, but we weren’t sure if the drill was turning the right way or if it was rotating backward. We still don’t know. Another thing we learned was how to cut circles out of using an X-Acto knife, which is a lot harder than it looks. We practiced cutting several circles before cutting out the prototype for the arm. We also learned how to be innovative while assembling things. For instance, we realized our motor was positioned too close to the top of the box for the arm to flip the switch, so we hot glued a diet coke bottle cap in between the lid and the motor.





If we had more time, we would have wanted to fix the box so that the wooden arm would always flip the switch. At the BPC Maker Faire, the box only worked some of the time, and about 40% of the time you had to flip the switch back by hand. We thought we could solve this by using a battery pack with a higher voltage, because ours had only 3 volts, or by using hot glue to secure the wooden arm to the motor. However, when we tried to connect a second battery pack, which was 3 volts as well, nothing would happen when you flipped the switch. As we didn’t have any battery packs with a higher voltage, we disconnected the additional battery pack. If we had more time, we also would have liked to create a similar box where an arm takes your coin from a tray and puts it into the box.


As mentioned above, we learned quite a few things from this process and now have a better idea of how to approach this project. If you were to build a useless box, we would advise that you use a 6-volt battery pack opposed to using a 3-volt battery pack as we did. We found that the 3-volt battery pack supplied just enough power and force for the arm to hit the switch. However, after using the machine a few times, the battery would get drained and you were forced to wait a few minutes before using it again. In addition to this, we would recommend securing the wooden arm to the motor with hot glue or another adhesive. This would ensure that the arm doesn’t wiggle and get out of place, for even a slight change in the position of the arm could determine whether or whether not the arm pushes the switch.


Overall, this project cost around $11. However, do keep in mind that most of these items were bought in bulk or in sets and not singularly. It is difficult to find places which sell these items singularly and purchasing the items in sets was more time efficient. Due to this, the actual cost would be greater than $11 if you were to buy the materials in sets as we did.


Our design was loosely based off instructions we found on the Autodesk Instructables website titled Useless Machine. We didn’t follow the design exactly, as the diagrams it showed were complex and we had trouble understanding them, so Lily’s dad helped us redraw the diagram in a way which made more sense. We didn’t use the same measurements for the box as the creators said to but instead estimated what we thought would work the best. We also decided to make the top out of wood, so that when people flipped the switch back and forth it wouldn’t wear on the foam which we used for the rest of the box. Our box was relatively similar to the one in the instructions, but it wasn’t the same.














Chicken Coop Basement - Maddy, Elliot, Sadie

Designing a Chicken Coop Basement
by Elliot, Maddy, and Sadie

Our (Sadie, Maddy and Elliot’s) project was to make a removable basement/lower level for Sadie’s chicken coop. All of us have very smart dogs who are great at breaking into places. The objective was to make it easy to clean, durable and dog proof. To do this, the plan was to have the basement roll out on wheels and to have a tray underneath to catch waste. Sadie previously had chickens and is interested in keeping pigeons. Because of this, we thought it would be a good idea to start rebuilding her chicken coop and have separate places for the different poultry.

We held the fact, in the back of our mind while making this project, that this would be a habitat for chickens. We also knew that chickens, like all life, produce waste, and that this waste needed somewhere to go. We made the floor of the coop be chicken wire so that the feces would be able to fall onto a tray below that we, humans, would be able to clean. We also knew that it would have to be predator proof, so we elevated the coop slightly off the ground and bought predator-proof latches for the doors.

Our project, because of the constraints of chicken safety and functionality brought up, needed to be exact. To make sure of this Sadie and Maddy drew out large and thought out images with whiteboard markers on a big surface at Maddy’s house. The whiteboard markers allowed us to erase and revise the diagrams depending on where our brainstorming went.

Because Black Pine Circle School has chickens, we had the opportunity to place a chicken in the coop to see about both sizings and to show other people what our project was about.

During the start of the project, we had a pretty good plan on what we were going to do. We would first convert the measurements of Sadie’s backyard chicken coop, create a small model, then build the final draft out of a hardwood. However, it was not an easy process. It took some work to make our model fit with the measurements of the pre-existing coop to make the new. Sadie made photo’s of the coop and added the measurements online so they were easier to interpret. This made it much easier to see what the measurements for the bottom floor would be. Maddy wasn’t there for the first three days and she had the materials for the coop. Elliot and Sadie had to wait until Maddy came back to begin the final draft and, meanwhile, created the small model, which was good in the long run as well, because the day after we finished the small model, Maddy came back and we could get started with a better idea then we had initially. We faced many other small problems and had to innovate. Some examples of this are: a 3d printed model taking forever to print, and then there is tons of support material on it; the screws were way too long, so we used nuts to shorten them, and not every tool was available to us at one time, so we used other tools for different tasks until that tool was available.

Throughout our project, we learned many things about the process of creating a functional structure. We made multiple models so that our final draft would be fairly easy to create and we would be pleased with our results. One of the models we made was a 3D printed model. By making a version on TinkerCad, we expanded our knowledge on how to build things on this platform. None of us knew how to actually print anything, so we sought assistance from a classmate and learned the art of 3D printing. We also learned about different tools and hardware pieces that were necessary for our project. For example, we learned how to use the circular saw and how to use a drill on a small piece of wood.

Within our time constraint, we could not finish our project but made the most of what we were able to get done. If we had more time we would complete it, doing things such as: cutting out doors, one for poultry and the other for human hands, creating runners and wheels to enable the floor to be a drawer for easy cleaning access, etc. Sadie intends to do this later in her free time. Even though we could not complete these elements of the project, we did plan them out. In our models, we included these. We also would have made roosts from strong sticks that we found in Maddy’s yard.

If anyone is looking to do this project, or one similar to this, such as building a dog house or other small structure, we would recommend creating accurate models that you can refer to when making the actual version. We did this and it helped a lot. Also, from our unavoidable mistakes, we learned that it is good to have your materials at the start so you know what you are working with.

If you are thinking of doing this project, it is good to keep in mind that it cost us about $64.97. Here is a link that shows in depth ways to start building a coop, link.

Making a Duct Tape Pencil Case


In this project, we were working to make a duct tape pencil case. We were going to use the pencil case, but because of a misunderstanding we lost it. Our inspiration for this project was that we didn't have a pencil case and we lose our pencils really easily, so we thought it would be good to make a pencil case.
The biggest challenge for us was making four sheets of double sided duct tape sheets. Due to the fact that when we touched duct tape it stuck to us,  combining two sheets of duct tape was extremely difficult and annoying.
When making a duct tape pencil case, we learned that it’s not as easy as it looks. Duct tape is really sticky and when you accidentally get two pieces of duct tape stuck together, you can’t get get it unstuck.
If we had more time, we would make a cleaner looking pencil case and we would make it into a supreme pencil case.
If you are able to be patient and calm, this project will be 100 times easier. Also, you need to get the right materials.
Estimated cost; 17.77


We lost ours, so here is a picture from google:

Eva and Scout Maker Faire Bike reorgonization on the feild

At our school, people get to school in several different ways. Some people go by bus, some go by car, some carpool, there are a couple who even walk, but our focus is those who bike. Biking to school is a way that over ⅙ of students get to school. Included in that ⅙ is us. We noticed more and more as the school year progressed, that there are problems in the system people use to bike to school.


The system we use for parking and storing bikes at school is simple. We have a series of bike racks lined up against a fence. This area happens to be on the side of the Addison building, where it is barely wide enough for a bike. For most of the area people can store their bikes, there is gravel laid down for a smooth bikeway. But for the other section, it is a driveway, that is very uneven.


There are several problems that this system presents. First of all, when we took a survey, we found that roughly 30 people bike daily. The other thing we calculated was that the current situation fits comfortably 15-17 bikes without any of them falling over. In addition to this, when there isn’t any more room on the racks, people park the bikes on the side of the building, which causes the people who parked in the racks to not be able to get their bikes out. But when someone tries to just cram all the bikes in on the racks, the bikes get knocked over, sometimes causing a ‘domino effect.’


To clarify, our goal is to redesign the bike parking situation in a way that is friendly to many different people. The inspiration was as such; we saw that the problem was affecting people’s ability to park their bikes at school and it was affecting their moods, and frustration before and after school, and we decided we want to come up with a solution. Our project was to design a new way to store the bikes that is compact, comfortable, and fits the number of bikers that actually bike. And the objective was simply to improve the system that affects everyone from bikes, to people playing on the field who were influenced by the bikes spilling over.


One challenge that we faced was simply brainstorming and coming up with a solution, but we eventually came up with an effective and compact solution by using vertical bike racks. With the use of vertical bike racks, we can fit more bikes in less space.


We learned a lot about how in every problem there are multiple sides. For instance, it was not only bikers who were frustrated, but also people using the field, because the bikes interfered with other games. If we had more time, the next steps would be to fully build and install the system that we designed. For any others looking to do similar projects, be sure to start prototyping early to have solid, 3D designs to present in addition to any drawings and/or pictures.


If we had more time to work on our project we would outfit the field at our school with 15 sets of these new vertical bike racks, but this would require about 1.5 hours per racks which would ultimately add up to 22.5 hours in total. As well costing around $250 for wood $34 for hardware and $96 for hooks in total is $380 for 15 racks.


   


Tilda and Amelia's 2019 Maker Fair Blog Post



Our project was to make a flashlight in an Altoids tin. We wanted to learn about circuits and how they work. Our inspiration for our project was to make an accessible light source. One challenge we had was that we were new to circuits and needed to learn about them to understand our project. We learned about how circuits work. It took us a long time to figure everything out so if we did this a second time it would not take as much time. If we had more time we would try to make the flashlight, solar powered or make it easy to recharge the battery on a solar panel, so we could use a more sustainable energy source. Some advice we would give to others is to really research what you are doing before you get too far in. An estimated cost of our project if we had to buy everything except for the tools, would be about 10 dollars. This is a really cheap project that anyone can do if you have the knowledge, tools, and time. This is the tutorial we used. It did not explain how to solder the circuit so we had to get help.

String Ball Chandelier

For our school maker faire, we decided to build a chandelier. We made this chandelier out of string and glue. We were inspired to make this after watching a lot of DIY videos. We eventually landed on a video of DIY home decor. Here, we saw someone making a lantern out of string, but the instructions were not clear, so we found a better video and decided that this would be a fun project.


First, we blew up a beach ball and then drew two circles on the ball. We drew a small circle on the top for the light fixture and a bigger one for the opening of the chandelier and to put the light bulb in. We then dunked our base white into the glue and started wrapping the string around the ball, making sure to avoid the circle boundaries. Once we ran out of white string, we repeated the process with the blue and pink string. When wrapping the string, we made sure to cover up any blank spots on the beach ball so that the amount of string was consistent all around. After we finished wrapping it, we set it on a drying rack and let it dry. Once it was dry, we deflated the beach ball and took it out of the now-dry string ball and put in the light fixture and light bulb and hung it up.

A challenge we faced was not having enough materials necessary to complete the project, so we borrowed these materials from our BPC art classroom.

If you were to make this yourself, you would need about $20 worth of materials, and a few hours of getting your hands dirty with glue.

(Bonus: Once the glue on your hands dry, peeling it off will be very satisfying. :))

Boatatron: A Way to Clean Trash by Charlie, Francis, and Jake





Boatatron
By Charlie, Jake, and Francis


Introduction

Our project was to help clean up trash in aquatic environments with a cost effective and sustainable way. We decided to create the Boatatron. The idea was that using the old motor of a remote control car we could create a buoyant semi-aquatic vessel with the goal of collecting trash. We call it the BOATOTRON©. We faced many challenges along the way but in the end it mostly worked. We were inspired because we noticed that a lot of water environments were haunted with trash. This helps the world and us personally, because our objective was to help resolve the problems that we (humans) have caused.

Our struggles and what we learned 

As many Maker Fair participants may know, having a problem during the making part of the Fair is nearly inevitable. Many of the problems were predictable, and even in our brainstorms they were pointed out, like waterproofing (already stated), moving fast enough in the water, the nets, and floatation. Having to convert a land-based vehicle to an aquatic vessel, waterproofing the vehicle was extremely hard. We used an excessive amount of duct tape (we could have used less to make it more sustainable) to waterproof it. Of course, we then learned that duct tape was not the stickiest when in water. So instead, we could use seals, and persisted meticulously checking for flaws in our prototype. Another problem was when we had to find a way to make it float. Charlie had previously gotten some old pool noodles, but we had to find a way to make it balance, so we asked Meyer for some ping pong balls, which he gave us. One large problem that we didn’t exactly solve was when we were cutting boards for support, and they were barely held together by duct tape. Fortunately, it still stayed together for the Fair. In conclusion, we were able to persist through the problems. 


How it works 

The original RC car had it’s back wheels as the motors and the front wheels as steerers. We removed all of the tires, and attached paddles to the wheels. We then took off the front wheels, and added a rudder on the steering function of the RC car. We then took the facade off of the car, and sealed it completely with packaging tape. After that, we added a plank of balsa wood to the bottom of the car, and put ping pong balls and parts of pool noodles on the balsa wood (for floatation.) After that we added strawberry cartons to the back (As nets to catch plastic). And finally, we added pocketed paddles to propelling.


Extra Information 

Total Cost: About 15 to 20 dollars, we only spent money on the RC car previously, but we also used some of the school materials (duct tape, seal, craft sticks, and lots of water for testing) People that helped: Leo, Kian, Meyer, and of course, Ms. Hill. We cannot express our gratitude enough for these people.

Foosball Stick Project - Adam and Oliver B.



Adam E. Oliver B. 
5/30/2019

Foosball stick Project

We have always liked playing Foosball at recess and lunch; unfortunately one of the Foosball Tables’ defenders broke. This was upsetting because it made the game very unbalanced and one sided, ruining a lot of the fun. We decided to take on this project because it resonates to us. So we decided to fix the table by making a new defender stick. We knew we would mess up along the way but we didn’t care because no matter how much worse the new defenders were then the old ones they would still better than nothing.

We didn’t need to design the stick itself very much but we needed to decide and design what we could do with the constraints that we have, these being 5 hours and $25. We decided that the best materials we could use were 2 pieces of 2 by 4, a steel rod for $8(this was the only piece that wasn’t already supplied), and a steel pipe. We also had to think about how we would get the stick in to the table, we couldn’t do anything too big because then we wouldn’t be able to slide it into the table. With these in mind we ended up making it nearly identical to the other sticks. Our stick didn’t have the springs on the ends like the others and ours wasn’t as balanced but ours worked fine.

One challenge we faced over the course of the project was the rubber handle that Adam brought from home was about ¼ inch to thin. We didn’t know how to fix it and the best alternative would be duct tape which wouldn’t be nearly as fun. We ended up trying to drill into it and sand it down until we finally found a tool that was meant to be used for this type of problem, unfortunately it was too small but we used it anyways. It was a sort of sharp bladed metal rasp and we ended up widening the opening with and hammering in the rod the rest of the way to make sure it didn’t come off from lack of friction.



In the process of making the stick we learned how to overcome challenges, learned that things don’t have to be perfect to be functional, and learned that working in a partnership helps you get work done faster. We liked the challenges and triumphs that come with bigger projects like these. If we had more time we probably would re glue the characters (we messed up once) to hold them better then just taping them. And we would most likely figure out a better way to glue the stick into the table. I would say if your looking to have some fun while doing the project do what we did, design your own stick and make it from scratch, but if you're looking for optimal functionality you should probably get a manufactured replacement.

Climate Change Awareness Movie

By Leo, Kian, and July

Our Maker Faire project was a movie about Climate Change. The point of it was to inform the people about what Climate Change is and the dangers of it. We knew it would be a great project because it is not too easy, movies are usually a great way of giving people information, and it teaches people that Climate Change is real.
While we were making our movie, one of the members of our group got cold feet about the project and kind of wanted to change it. He started getting less enthusiastic about the project, which affected how much we accomplished each time we were working. Once we got to the more exciting part of the movie, though, this person started working harder and we finished the movie on time.
We ran into some problems while making the movie. Some of these challenges included not wearing the same clothes every day, not having the rooms we planned to film in open, and convincing student who did not enjoy the movie that it was okay. If we had more time to work on the movie, we probably would have re filmed another science scene, because the camera didn’t show the full thing. If anyone else ever tries to make a movie, make sure you really want to do it, because it requires a lot of patience.


Our project did not cost any money. It did require us to materials such as an iPhone, scripts, Chromebooks, and costumes. We happened to have these items beforehand, which made it easier to make our project.

Methane Harvester


Dylan S. 6B

Methane is one of the worst greenhouse gasses commonly being produced, so my project was to try to create a design that would harvest methane to grow plants.
I was inspired when I discovered that if you burn methane, it produces water or water vapor, and carbon dioxide. I immediately noticed that along with sunlight, those two are the main components needed to make plants.

A challenge I faced when creating a design for a methane harvester was the quantity of research necessary for the ability to accurately determine the proper amount of material I should be expecting. I had to do extensive studying into the properties of plants, cows, and various gasses. I ran out of time in the end, and was forced to complete the drawing at my house, but I am happy with the end result.

The next step would be building a small model of the barn. An approximate cost per year would be about 9,000 dollars for the 100 cows and 25,000 dollars for the greenhouse. Along with other costs, the price of a 100 cow greenhouse could be about 35,000 dollars. While this amount of money might be a problem for some, greenhouse gas emissions are more of a problem if not handled properly and quickly.

Food Storage Done Another Way: Replicating Plastic Clamshells Using Recycled Paper By Miles Reichmann and Julia Fromson-Mayhew 6B-13




While searching for ideas for a Maker project, we started to think about the food industry, specifically what we saw in grocery stores. We noticed how many things are kept in plastic clamshell containers, even things that don’t need to be, like cucumbers. We asked our parents about why they thought things were packaged this way and they said they thought it was because of how easy they are: they are stackable and protective. We knew that these containers were plastic, but they didn’t need to be. We wanted to create a new way to package these foods, without losing the convenience of the clamshell.  We thought about alternatives to plastic, and paper immediately came to mind. We decided to replicate the clamshell containers we saw in the stores, but with recycled paper.
Our Maker Faire Booth
The first step in our design process was figuring out our problem, which was how much plastic is used in the food industry. We then had to identify our criteria and constraints.  Our project had to be under $25, so we decided to use common household items like egg carton containers and paper from the school recycling. Like all the other groups, we had a limited amount of class periods allotted to working on our project.
We composed two different prototypes for this project. The first was made of shredded egg cartons mixed with wheat paste, and the second, paper blended with warm water.  We did not get a chance to revise these very much: the model with the wheat paste dried and worked properly, while the other did not. (See “challenge” below.)
Putting it on the screen
One challenge that we encountered in our process was that the paper wouldn’t dry.  One of our models was made of paper pulp applied to the inside of a plastic clamshell container, brought in from home.  The problem was that the water would drain out of the paper and get stuck in the bottom of the container. Since it was plastic, there was no drainage, and the water was re-absorbed by the paper pulp.  We called this “The Plastic Effect.” There was another group who was also making paper, and theirs was drying on cardboard. When we tried putting scraps of paper into the clamshell as a liner, it only made the problem worse.  Our solution to this problem was to use different materials. Instead of using water in the paper pulp, we shredded egg cartons and mixed it them with wheat paste. This was able to dry better because the wheat paste was less liquidy and left behind more of a substance when it dried.
Our project was completely free, because we only used things that were already available to us. We brought clamshells and egg cartons in from home, and raided the school recyclings for the paper scraps. The only thing that might be an issue if you try this at home is the paper screen: we already had one at school. You can easily make one by stretching wire mesh across a picture frame or even just using an old window screen. A few links that helped us were Making Your Own Paper and Egg Carton Paper-Making.
First Prototype
We learned a lot in this process. We learned about different ways to keep paper together and different forms of recycling. We also figured out a few things about what makes plastic effective. For example, in “The Plastic Effect,” the plastic is meant to be trapping liquid, which is what makes it effective for things like milk cartons and water bottles. By figuring this out, we were able to find ways to make paper more effective, even if we weren’t able to execute them in the time given. If we had more time, we would have liked to try to mass-produce our model and make it more widely available to stores. We also would have liked to try to create models of some of the things that would have made it more effective.

Homemade Organic Dog Treats - Sophia A. and Elliot C.


          At first, we didn't know what to make for our Maker Project. We originally wanted to make a candy machine, but we found out we couldn't do that because it didn’t help the earth in any way. Then we decided to move on to a dog feeder because we know how lazy people are when it comes to feeding their dogs, but we found out that we couldn’t do that either. We finally made up our minds and decided to make healthy organic dog treats. We wanted to make sure that dogs had the healthiest option for their treats. Some dog treats are bad for dogs and have chemicals that can harm them, but our dog treats are fully organic and won't harm the animals. Something challenging was that we would find recipes but then see that they weren't very healthy, so we had to keep searching.     
           We planned a day where we would bake our first batch of dog treats. We baked our first batch on Saturday at Elliot's house. They were a success! My dog ate three cookies. We felt successful and accomplished. We had a little trouble because Elliot was sick, so Sophia made the dough on Tuesday without Elliot, then Elliot came back on Thursday and we baked the treats. The next day it was already the Maker Faire! That morning we had two periods to finish up, in that time we made our glaze and glazed one batch of treats. We made two batches of dog treats. We made Cranberry Coconut dog treats and Peanut Butter Pumpkin Dog treats. We used Sun butter because of the allergy of someone at our school. 
          Something we learned is that, sometimes you have to edit the recipe to make them better. For the first batch of dog treats, we added 1 extra egg, 1 tbsp more almond flour, 1 tbsp more coconut flour, and 1 tbsp more coconut oil. Something else that we learned is that not all things turn out how you want them to, for example the Peanut butter Pumpkin dog treats didn't taste like we wanted them to, even though the dogs liked them.
          Even though the dog treats were a huge success and even people liked eating them, we would make them better by making them even more healthy. We could not use bacon grease next time because it has fat, we would maybe eliminate or use less peanut butter. Our project had a overall cost of $30. If you are thinking of making this make sure to follow your instincts, example: not following the whole recipe exactly. We thought that this project was really fun and enjoyed working together.

Pop Tab Jewelry, Nella S.



Pop Tab Jewelry, Nella S. 6B

For the 2019 Maker Faire I decided to use recycled pop tabs to make jewelry. I really like working with metal and making jewelry and I recently found out that only 9% of the materials we recycle don’t actually get recycled! It’s only thrown into the landfill like regular trash. I decided to choose one recyclable material I noticed we used a lot. At first, I wanted to make jewelry out of recycled paper. But I couldn’t manipulate the paper they way I wanted to. So later I chose pop tabs and started to work with them to turn them into jewelry. Lots of people drink sodas and recycle them or throw them away. But, they can be turned into beautiful pieces of jewelry you can wear comfortably. So from there I started developing the best way to manipulate the pop tabs.

I went through many ideas and designs starting with paper quilling (the rolling and gluing of paper to make designs) than using wire to connect the pop tabs, but I finally decided on using ribbon and threading it through the pop tabs. I also used wire cutters to cut through the pop tabs and connect them but that method caused the pop tabs to become pokey so I only used it for earrings. One challenge I had to overcome was how to make the pop tab jewelry comfortable to wear. As I mentioned before directly linking the pop tabs using wire cutters caused it to become scratchy and almost painful to wear. I had to come up with another solution fast. And so I decided to use the ribbon and it made them much more stylish and comfortable to wear! I loved the look of the colorful ribbon and it seemed like everybody else did too!

To make the ribbon pop tab jewelry take a pop tab and thread the ribbon through the holes and over the middle bar. Than loop more pop tabs on to the same ribbon and continue this process until you have reached your desired length. To connect the ends just tie them together around your wrist, ankle, or neck. To make the earrings I cut through the two pop ends of the pop tabs and linked them together into fun shapes! This project was so much fun and I really recommend it for a boring rainy day weekend or any other time you need a fun craft.

Simple Accessible Water Filter: DIY






Simple Accessible Water Filter

      I wanted to solve a problem that would both benefit humans and the environment, so I addressed the issue of polluted and unsafe drinking water. I know that many people in the world don’t have access to clean drinking water or a good water filter. My goal was to design an easy, inexpensive, functional product that can turn dirty water into safe drinking water so that it could be remade and reused on a global scale. But first, as you always have to do, I started small.

      I started by researching what makes a good water filter. What I found was surprising to me. I didn’t realize how easy and inexpensive this would be. Most of the resources that I used to build this, I didn’t even need to buy, (it only cost about $10-15, but I had extras of all the materials, so it could be made three or four times for the same price) and it is all contained in a small plastic water bottle. Here’s how the initial design was supposed to work. Firstly, it goes through gravel, which takes out larger things, such as leaves or insects. Then the sand gets rid of smaller particles, like dirt or algae. The activated charcoal gets rid of very fine particles and chemicals through chemical absorption. Finally, the cotton balls at the bottom strain out the residue left by the other things. So I started with that design.

   
      There were more than a few problems with my first design. First of all, it didn’t work. Dirty water going in only got dirtier as it came out. Also, the top had been cut off to put the stuff in, but if it tipped over, everything would easily spill out. And lastly, the water going in started to flood it and move things around. So I went back to the drawing board. I decided it was probably the charcoal that got the water dirtier, so I added more cotton balls at the end, but they started falling out. To fix that problem, I put the cap back onto the water bottle with a tiny hole so the water could drip out. Then, I put a coffee filter at the top, just for a bit of extra straining. Finally, to address the issue of things falling out, and the issue of flooding, I poked a small hole in a yogurt cup and attached it to the top. That meant there was something to block things from falling out, and it had a constant, slower inflow into the filter so it wouldn’t get overwhelmed.

      I tested it again by mixing dirt with water and pouring it into the filter, and it surprised me. After about 20 seconds of waiting, a constant drip of clean water came out of the bottom. It looked clean enough, so I decided to have a sip. It tasted a bit earthy, but pretty fresh and good. I think if it keeps being revised and getting better, it can be made to make water clean enough to drink safely. If you do this, keep experimenting, and try to get this project to completely work!

Scribble bot Ari M and Noah K

Our maker faire project was making a scribble bot. A scribble bot is a cup with markers on the bottom, and a motor on the top to make it spin. It draws stuff in circles, with different colors. We made the scribble bot because it’s a fun project and it’s cool to see how it draws. We can vary the size and shape of it and see how it affects the drawings.
How we found out about this project was that one of us looked up “cool maker faire projects” and after a while, we came upon this project. This project drew our eye because we’ve seen this before and we thought that it was really cool. We thought it would be way more complicated than it actually was.
We learned that if the first design for a project doesn’t work, then you might need to tweak it. For example, our wires weren’t sticking to the motor, so it kept stopping. We then used tin foil to help the wires stick. If we had more time, we would probably hook up the motor to an arduino, so we could give it commands. Some advice for doing this project is to align the markers so that the scribble bot isn’t off balance.
We didn’t spend any money on our project, because we just used materials that we had or that the school had. But the estimated cost of our project is about $10.
One of our challenges was getting a can to use, so we decided to use a cup instead. It didn’t work as well, because it was less sturdy, but it got the job done.

Climate Change Board Game: Terrafirma - Augie, Nate, and Eli





Maker Faire Blog Post about “Terrafirma"

By: Eli Mckoy Beiser, Augie Nice, and Nate Sommer

Our Maker Faire project was called Terrafirma. It was a board game where you would try to run a civilization. You had to make sure your civilians had food, water, and energy everyday. you had to build farms, water purifiers, and factories to provide those things. For everyday your civilians had these things, you got a point. Now for the hard part, getting these things for your civilians required you to put Co2 into your civilization’s atmosphere, we would add 10 Co2 to your atmosphere for every farm, water purifier, and factory you had per day. Once you added 400 Co2 to the atmosphere, your civilization would come to an end. So your goal as the player was to get as far as you could while keeping your civilians alive. The objective of our project was to make people more aware of how hard it is to provide people with their needs, while also balancing the trouble of climate change. Our project has very specific examples, and there are more problems you will encounter in running a civilization. One thing we thought was that people thought we should just get rid of fossil fuels, but those are how tons of people get energy. So our objective was not to tell people that fossil fuels are good and everyone should use them, but that thoughts saying to just get rid of fossil fuels should be given a better solution with more thought, we’re letting people know that solving climate change is a bit more complex than some people think. We were inspired to do this project because we have been talking about climate change a lot in school, whether it be a movie about it, or a science project about it, we talked about it a lot. This made us think more about that problem and we thought this would be the perfect opportunity to make people more aware. We only had two weeks to make this project so we had to work quickly while still making people aware of the complexity in climate change. In this time we think we still managed to make a fun game that still communicated the message we trying to get across.

The biggest challenge throughout the process of making this game was figuring out what our numbers would be, and how they would work. For example what number of Co2 would they have to have for their civilization to end. We overcame this by making a plan one day, making sure it worked, and then just changing things that didn’t work. For around 2 days we were testing numbers with people in the class to see what did not work for us. In fact, on the day of the faire we had to change a few numbers to make sure everything worked smoothly. In the end all our numbers worked fine, but it took awhile to find the numbers that worked.

So, Terrafirma was full of ups and downs. However, we learned a lot in the process: How to make the numbers work so that it was possible to play the game, how to adapt our original idea to fit constraints and problems that came up during our work process, and how to stick with a project even when it starts to look hopeless. But when we were done, we still felt like there was so much more that we could have done. For example, if we had more time, we would have made the game more pleasing to the eye, as we kind of had to rush the cutting and gluing of the buildings, they were made of cardboard which made it harder to look perfect. We also would have added more variables so there were more than one strategy to play. However, if you want to make a climate change board game, there are some things that we would suggest. First, plan everything! We thought that things would fall into place as we worked, but this was not the case. In addition, don’t rush the making of the game itself. It is very important that it looks polished so that people want to come and play your game. Lastly, play test as much as possible. The more you play test, the more likely it is that you will catch errors and make the game more fun to play and less hard to run.

In our project we used all school resources: paint and markers from the art room, cardboard and cardboard scissors from the maker room, hot glue from the science room, wood from Ms. Hills farm. So we spent no extra money on our project.

Project MagLevation: A Magnetic Levitating Train. By Kate, Oliver Hu, And Ohad.



Brought to you by Oliver Hu, Ohad, and Kate

            Our project was creating a magnetic levitating train. We were inspired by the MagLev, a company that builds magnetic levitating trains, one in Shanghai and one in Japan. We wanted to build this because if this technology is advanced it could reduce greenhouse gases from cars, trains, and other transportation that heavily leans on gas. It’s a good deal if we start to use magnetic levitating technology, because, first; it helps keep the Earth clean and healthy; second, since the Earth’s supply of natural gasoline is dwindling, this will be a good, clean alternative. But it is also has a bad side because it costs $60 million to make a mile of track. Most high speed train tracks cost $7.7 billion for 3,150 miles of track. Our objective was to make a fully functional train that could float, move, and hold things on its own. We realized that this was going to be hard after a week, so we changed our goal to make it float, move, and hold, but with help.

            Over the course of the creation of our magnetic levitating train, we faced many challenges. One of them was that we couldn’t get our train to move. After a lot of trying, and failing, we made our train levitate. But still, it wouldn’t move! We tried placing magnets on the walls to force the train into the middle of the track where there would be less friction and the train would be able to move easier. However, the magnets on the bottom of our train were attracted to the sides of the magnets on the walls, so it just flipped over. Then, we had the idea to use wind power. We made two sails, one out of cloth and one out of plastic and attached it to the train, then put a fan behind the track and turned it on. But that didn’t work either; the train was too heavy and the sail just flapped while the train stayed in place. So then we tried to attach a magnet to the back of the train and push it with another magnet from behind. But that just pushed it off of the track. At that moment, when all hope was lost, when we were considering just not having it move at all, it hit us. Instead of push, we could use pull! We moved the magnet to the front of the train and then pulled it with a magnet. It wasn’t perfect, but it worked.

            We learned that magnetic push isn’t always stronger than magnetic pull. We pulled our train with a magnet using magnetic pull instead of pushing it with repelling magnet. We also learned about new ways to move objects without using fossil fuels. We were brainstorming ideas of how to move our train. We thought of wind power, solar power, magnetic power, and gravity. First we brainstormed, thinking of what to do and how it would work. We eventually decided to move it through the power of magnets. Then we started gathering materials and making a rough draft. When the rough draft was done, we started creating the track and the train. Then we noticed all the problems and found some answers. First we found out that our train was too heavy to keep on the track. Our solution was to make a train out of cardboard instead of making it out of wood. We rebuilt our train and then we were done after a few more tests. Our future steps would be making an engine for the train and making a good way to keep the train on the track. We would want to keep on improving the track to make one of the first hyperloops. A hyperloop is going to be the fastest train going at speeds of around 700 mph. The hyperloop runs on a magnetic levitating track but also is in a vacuum. This makes even less friction and making higher speeds possible. For others doing the same project we would recommend making the lightest train possible because not all magnets can hold too much weight. Also ask others around for magnets because it can save lots of money. We got all of our magnets from Ms.Lockwood and made our project completely cost free. Remember to always get back up after every fail. You will never get anywhere if you stay in the same place.



            Everybody hates traffic. We empathize with our users by finding a problem that people would love a solution to as well a problem for the climate. Our objective was to reduce the amount of cars on the street on a daily basis. We thought that public transportation was a good solution to that, but that too released carbon dioxide. We thought that if we could make a method of public transportation that did not release carbon dioxide, then the problem could potentially be solved. And thus came the idea of the magnetic levitating train. There are two magnetic levitating trains that exist, one in Japan and one in Shanghai, and they are among the fastest trains in the world. Our prototype did not work, when we tested it we realized that we needed walls to hold it in place. So we added walls, and found another thing wrong with it, and then we fixed that, and on and on until we had our final product.



            Our project costed a total of zero dollars. This is because the lower school had done a similar project in the past, so Ms. Lockwood was happy to let us borrow the magnets and other necessary components that we needed. We used a couple of resources in the creation / brainstorming for our Maker Faire project. Here they are:

Rose and Lenka's Maker Fair Project - Recycling: Taught by Gummies

                          


For our project, we made gummies shaped like recycling symbols. We realized people don't know a lot about how trash gets sorted, especially the kids in the lower school. So, we tried to think up a way to reach the little kids. We thought about what would've gotten us interested when we were that young; food! But our food couldn't just be regular old food, we needed to make it relating to our trash sorting problem. We were going to make them shaped like recycling symbols using a molding putty we found on amazon. We quickly realized that we needed something to push in to the molding putty, so we made our own TinkerCAD design. At first we thought about making them out of chocolate, but chocolate was too expensive. We then did research about making hard candies, but for that we would need around 10 cups of corn syrup, so that was not going to happen. Then we came across a recipe gummy bears using jello, it was cheap and easy to make, it was perfect. The estimated cost for our project was around $45 which was a little under our money constraint. During the science fair if kids wanted a candy they would have to answer a question about trash sorting, for example, a question might be, "Where would you put this empty soda can: In the landfill, recycling, or compost?"

One challenge we had was with our TinkerCAD design; we needed to press it into the molding putty. We had tested our 3D printed design two times, finally working the second time, and then we realized we couldn’t print it because Ms. Mytko, Ms. Hill, and Mx. Mason were all at the San Mateo Maker Faire with the seventh graders. The big printer was also at the Maker Faire. So, we used a computer from the FAD to email Rose’s uncle to ask if he could print it for us since he has a 3D printer at his house. He printed our eleven hour print and delivered it to us in time for class on Monday!

We learned a lot in the process of making the gummies. For example,
to make candy you have to be really specific with your recipe and know exactly how much of each ingredient you need, because if you mess one thing up your whole batch could be ruined. You also have to give yourself realistic time checks, because most candies take a long time to set and you will need time to get your ingredients together and check your recipe. If we had had more time, I think we would’ve tried to make some of our candies out of chocolate and candies instead of just doing gummies out of Jello. Our advice to others attempting something similar to this would be to plan out the whole project ahead of time, find a doable recipe, and make sure you have enough time to finish your project.

A Recreation of a Tiny Home

A Recreation of a Tiny Home

Our project was to make a recreated model version of a tiny house built specifically to minimize space in the house and cost of the house. We were inspired by the Blender Bike, a previous Maker Faire project. We know that house prices have gone up drastically and it’s often hard to find a place to live, on top of that, homeless people are often kicked out of their only living spaces by the police and government. Sometimes they don’t like to live in homeless shelters because they feel that it can take away some of their freedom and independence. We also wanted it to be easy for them to move and sometimes it can be dangerous to drive, so we wanted to do the recreation of the tiny house on a bike instead of a car.

One of the challenges we faced was how to make a tiny house the appropriate size, while still keeping the pricing an affordable amount. We solved this problem by calculating the pricing with reused wood which lowered the pricing down by quite a bit. Another challenge was that when making the fold out bed, it could not unfold properly because of the installation on the walls. We solved this (with a little help from Eli) by cutting the armchairs of the fold out bed to be more curved.

If we had more time, we would have made the actual trailer, managing the costs and material problems along the way. With our model, all our materials were from school, and we only had one basic material. Cardboard. It was all mapped out, with a to do list, and we didn’t actually know what it would be like if we put it out on the road. Would it crush under the weight? Would the wheels be big enough? Would it tip over? Could someone ACTUALLY get a good night's sleep in our trailer? All these questions would be answered if we made the real trailer, not just the model.

We learned that most cities have a 72 hour time limit for parking. In the early stages of researching, we thought that the parking permits would be hard to research, and that we would have to contact the government, or read through hundreds of documents. Really, it was pretty simple.

If you were to re-do our project, make sure you get your measurements correct. We learned that if even one piece that was a little bit off, it had to either be re-done, or the space filled in with hot glue. Also, remember to have it all planned out. Before the project started, we made a long to-do list. We would each do one job, and then re-group to discuss what we had learned. It was really helpful, because then everyone always had a job to do, and we always knew what we still needed to do. Just remember to never skip any steps. They’re all equally important to making a good project.

Our project consisted of all materials that were already in school, so our overall cost for the model project was $0.
