Custom Doorknob Mechanism
Custom Doorknob Mechanism
A couple years ago the doorknob to my room broke and I decided to design my own from scratch. I used Tinkercad which is a very simplified CAD software. Using a higher level software such as SolidWorks would have made this much easier, but I was not experienced in CAD yet.
I used a cam
And I obviously chose to make it Star Wars themed

My Aunt printed the text for me on her vinyl cutter and I spent hours placing each of the letters onto my box

Microwave Fixing
Recently, my mom's microwave broke and I took it all apart to diagnose it. I eventually discovered that the high voltage capacitor was not working properly and I ended up replacing it. Instead of spending hundreds of dollars on a new microwave, I fixed the old one with a $10 part.

My friend asked if I knew anything about this issue he was having with his mini fridge. I ended up unplugging many connections and individually testing components. My favorite part was testing the thermoelectric cooler. If you applied 12 volts to it, one side would heat up, while the other side would cool. This was back in my hometown, where I did not have all of my tools such as a power supply. I ended up getting some wiring from a doorbell, and 8 D batteries, and connecting them all together in series to the thermoelectric module. We discovered that it performed as expected, but when unplugged, other components of the fridge worked. This led me to believe it was some issue with the power supply on the board. I did some more debugging with a multimeter and noticed that one of the capacitors on the top left of the board was slightly bulging out. I decided to replace it with one from an old PC power supply with the same specifications. This one capacitor was the problem that was stopping this cooler from functioning.
