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.

What is Matlab and what is it used for?

I am about to embark on a journey of knowledge and learning, to elaborate I will learn the basics of Matlab or at least as mush as I can squeeze in, in a month, I will also discover what is it used for, and I will document my process and acquired knowledge throughout this blog. First things first, what is Matlab? Matlab is a multi-paradigm programming language that allows for matrix manipulation, plotting of functions, implementation of algorithms, creation of interfaces, and interfacing with programs written in other languages. Basically you can do in Matlab what you can do in any other programming language the difference is that Matlab is more number based, and makes more emphasize on Math itself. Now that I know what Matlab is and what is it used for I can now create my own account so I have access to Matlab and I can I use it freely. At least for a month. I can't show you the creating an account process but I will show you how Matlab's interface looks like. Now for the fun ...

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...

The next week: A penny battery

A penny battery seemed insane, especially at the beginning of the year. The penny battery started off by getting all the materials, which were: 5 pennies, 1 with both sides of copper and 4 with 1 side of copper and 1 side of scraped copper. A small metal piece, which is where I'm going to be putting the penny stack. 4 small pieces of paper. Vinegar and salt. This is the setup of the penny battery, the pennies are stacked up with pieces of paper in between, the pieces of paper were socked in vinegar and salt, and all of it is on top of the small metal piece. Then I noticed that the metal piece was not necessary and that the pieces of paper were too big so I fixed the battery, at the same time I used the voltage meter and it gave me 2.6v which is quite a lot because a triple-A battery is 1.5v. With the 2.6v in my battery, it was now time to try lighting up an LED, this was actually one of my favorite experiences in the shop class. I l...
