Random/Miscellaneous

A lof of my projects weren't well documented enough to get their own section (and a lot of them are too ridiculous or useless to deserve one). I've put the rest of the photos that I have here. A raspberry pi submerged in mineral oil An excuse to put a raspberry pi in a box of mineral oil. The Raspberry Pi is overclocked and a close friend wrote a program to plot the CPU temperature over time. The liquid cooling actually worked!

A diy Newtonian Reflector My DIY Newtonian reflector
I gave a presentation about hacking the GPIO functionality of an RTL-SDR Dongle at the Society of Amateur Radio Astronomers (SARA) Conference 2019.
The contacts used for a DIY touchscreen enabled wall I did some work on making a wall scale capacitive touchscreen at the Makerspace where I worked.
Paste Extruder in Action Disassembled paste extruder I made a paste extruder for a 3D printer at the makerspace where I worked. The upper photo shows it printing with royal icing. The entire mechanism is my design, I 3d printed most of the parts and laser cut the gears out of acrylic.
My antenna tower I built an antenna tower and mounted it on my roof. In this photo, it has a 134MHz V dipole for receiving APT from NOAA weather satellites.
I used the DE1-SoC for one of my digital design courses to build the glue logic and memories for a Z80 microprocessor.
Evaluation board for DAC5687 I made this DIY breakout board for the DAC5687 for developing the DDS.
A view of the temperature controller system A view of the peltier module and heatsink for the TC system A graph of temperature over time for the temp controller I was interested in making aluminum PCBs, so I designed one that fits on a heatsink and supports a single temperature sensor IC. When the device is sitting on my desk, I can see my air conditioning turning on and off, but when I set up a PID loop on an arduino with the peltier module, the PCB temperature is held relatively constant.
My solar power system A custom latching relay driver on a breadboard I've designed solar power systems a few times, but none of the had even been built and I wanted to develop some intuition for how this stuff goes together. I bought the cheapest parts I could find, and I took the opportunity to have some fun building a completely analog latching relay driver for the UVLO on the load.
A DIY emc probe I built an EMC probe using soe RG316 coax and a ferrite bead, using the EEVblog video as a guide. I printed an enclosure for mine.
