This is a video of the projects on my workbench. This is a preview of what I'll be posting about in the coming weeks. Also, I will be keeping schematics, diagrams, PC boards, and source code on the upcoming TheVaporTrail website.
All but one of the projects use the PIC16F628A microcontroller. The other (the circular arrangement of LEDs in the lower right) I started twenty years ago and still haven't finished, and uses a 555 timer and TTL chips, including a 4-bit up/down counter.
