What I learned throughout the year

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.

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

This over here is where it all started. The year began and in my 7th period, my intro to engineering class began. I remember being completely new to the school so I didn't know any of the teachers, once I walked into the class I remember that it was absolutely not what I expected, although the teacher was really chill and smart, so that was pretty cool. The first assignment of the year(at least for me, because I started a bit late) was to make a sketch on a piece of paper, Mr. G the shop teacher was going to help us step by step. This is how the drawing really turned out, since Mr. G was helping the class step by step, the drawing looked really good, here's a photo of the final result.
