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 learned a lot throught the process of making this battery.

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...

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...

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 t...
