This part of the site will have some of my electronics projects I've built lately.   I have a "Lab" in the creepy basement that I have my electronics parts, power supplies, and tools centralized and it's also where I do my 3D printing.  I've including URL links to properly credit the authors of the projects where I used some of their components or software code, but over time the normal update cycles for software could render them nonoperational.   Good luck.  Pic on the left shows one of the three Arduino microcomputers running the flight simulator I built.   

This is an Adafruit.com build (Pi Eyes) that I've used for Halloween decorating.  There are a handful of different eyes (regular, snake, etc.) that you can use.   I plan to make about a 1/2 dozen of these to put around the yard like creepy humanoid rats hiding in the bushes.   But for now, I use two 24" displays in separate windows at the top of my house to make the house look alive.    Very cool effect (short video used for this page banner).   I put my Pi4 in a replica IBM PS/2 enclosure for this project.

Another Pi project that I use on Halloween.  I put a motion sensor in a skull with an ethernet attachment to a PI inside a water resistant box.   The Pi senses the motion as people approach the skull for trick-or-treating, and then plays a random (1 of 6 currently) .wav files of people screaming.   It also flashes two sets of lights -- in my case a purple and orange set of "Christmas" light sets.   It wakes people up for sure and adds another sound dimension to the festival display. 

I needed a clock in my lab and thought, why not build something fancy.   I found the plans (electronics and 3D STL files) online and made this.   The 3D prints took about 2 days, and getting the correct electronic components took another month.  Date and time are kept in sync via Wi-Fi on the mini ESP32 board (Coded using Arduino IDE).
