This week, I finished up making my UFO design, and it looked pretty much how I wanted it to. It looked kind of basic when I first made it, though, so I added in some windows around the top of it. I wanted to add in a little alien, but I realized it would be too small for it to accurately print, and the magnet was also in the way. I then printed it, and at first, when it came out, the magnet was a very tight fit, even though when I measured, I gave it a little bit of extra roo

This week, I finally got everything to work, and I'm happy it's finally complete. At the start of this week, I was mostly focused on the breadboard and trying to get it to work again. Last time, I had made the mistake of not making sure everything lined up perfectly. After I made sure the breadboard worked and aligned the parts on the PCB so that they lined up with what I had on the breadboard, I got to soldering. I had to resolder the sensor wire, but I also soldered the PCB

This week was mostly testing, as well as looking at an auction and touring a college. The first thing I did this week was figure out what was wrong with my breadboard. I was testing, and I figured out that the Hall effect sensor was getting extremely hot very quickly, so I realized the issue was most likely there. Last week, I had replaced the sensor I was using before with a new one, and I thought I was using the same one, but it turns out that they were actually different.

I started this week off by finally soldering my entire pcb, it took most of class since there are a lot of parts, so I only got to test it at the very end of class on tuesday, but it didnt seem to work, so I needed to test it with a multimeter, I suspected the hall effect sensor was not working, so I decided that I would replace it. The next day, I worked on soldering on a new sensor, and this time I added heatshrinks, since the wires are pretty close together, and since they
