Shell Eco Marathon Journey

 It all started when Mr. G, my advanced engineering teacher had the crazy idea of enrolling us in a competition called the Shell Eco Marathon, which is only a car building competition where the winner is whoever's car travel the most miles per gallon with only 100 ml gas tank. For the competition there is two types of cars you can pick, the urban design and the prototype, my team chose the prototype design which looks something like this.














This year's shell eco marathon was different than past ones thanks to the global pandemic we are undergoing, my team only focused on passing the virtual tech inspection using a free cad program called Onshape (The image bellow is an example of what you can do.)














My team consisted of approximately 8 students all of which had individual jobs, for example I was in charge of the electrical components of the car but later on I focused more on the bulkhead and the parts belonging there.

Once we determined the roles of each individual we decided to take a brief look at the shell eco marathon rule book, in the beginning of the year I focused on the electric systems and electrical components needed such as the kill switch, the starter, and the horn. Here is a picture of my horn design:
















Now I'll shift my focus from the electric parts to my real contribution to the team, which was the bulkhead. To clarify the bulkhead is the part of the car that separates the passenger cabin from the engine station where most electronics are located, the purpose of the bulkhead is to protect the driver in case of any explosion or short circuit. The bulkhead looks something like this:















This is an image of the bulkhead I came up with in cad in has several components that are needed such as the gas tank, psi tank, and the flow meter:

















The picture above was more of a rough draft now I only needed to make it fit the body perfectly, and here's how that looks:

















This is how the final bulkhead model looks, it's a simple design and it fits the hole body meaning it fully protects the driver.

Highlights

 2020 Project Highlights As the school year started my advanced engineering teacher had the crazy idea of participating on the shell eco marathon, which is basically a competition where you and you're team are supposed to build a car that consumes the least amount of fuel possible. I got in-charge of the electronics, which was basically the horn, the kill switch and the ignition system, I will not be talking about all of this in this post only the highlights. One of my first assignment of the year was to work on the horn's circuit, so here's a photo of what I came up with. I used the appropriate electrical signs, and I learned a lot from this project. This is the final result for the diagram, which includes the battery, the horn, the button, the relay, the fuse, and the wires of course. After finishing the diagram for the horn, I started learning about fuses, so I began to watch a bunch of youtube videos that talked about selecting the correct fuse size. I even used the for...

Quarantine: Projects

In this quarantine, I've had time to make a handful of projects my favorites being: DIY Galvanometer(battery tester) DIY Balance scale DIY Motor DIY Galvanometer My DIY battery tester was one of my favorite projects. The materials needed are in the photograph. The completely functional Battery tester is down here: Video:  https://drive.google.com/file/d/19Gfo9sgmO250ahzpP3CtPzav-lfIFgTD/view DIY Balance scale The DIY balance scale project was actually fairly simple, but it's fascinating how it works and the math involved in it. These are the materials used in the scale. The setup is also fairly simple. There's really not much of the project so ill just try to explain it. The idea of the scale is to figure out how much an item weighs depending on what the other item weighs and the position of that item, I won't show you the math because it's really not that intrusting, just take my word for it that it worked. DIY Motor Th...

Shell Eco Marathon Updates

Ever since the shell eco marathon started I have contributed by making several parts on Onshape, some being most electrical components and the bulkhead system that goes in the back. Currently in late May of 2021 I am working on connecting the system in the bulkhead with hose, pipes, and brackets.  More specific I am working on connecting the flowmeter and the engine through a hose, and it looks something like this: Now that I've shown you the general idea of what I'm working I can show each individual part and its specific purpose. The only purpose of the hose is to connect components, in this case the engine and the flowmeter. After making the hose I needed support, meaning I needed some sort of bracket so that the hose isn't just floating there in mid air. After making this bracket I downloaded a piece that I needed which goes on top of the bracket and allows for the hose to go through it. I added the necessary bolts so that it was realistic and this is how the final prod...
