Early wannabe EE aspires to stuff too much into too little and gets carried away. I actually got sidetracked with a dumb idea of making complex animations on a character display, called the thing “Juice Box,” set it up to play the Mario theme song on a piezo and did a whole intro thing that kinda took away my motivation to program the voltage monitoring and digital potentiometer, or something like that. I forget what the hiccup was exactly. This was back when I was still willing and naively going through massive physical ups and downs with disability from my broken neck/back. I probably put it away in one of the 3-6 week stretches without much sleep at all and never managed to come back to it. It is the same story with most of my hardware projects, and why I may seem quite capable, but will readily admit I’m pretty much useless in my physical shape overall.
At one point it was all in KiCAD. This was like 6-8 years ago. I don’t recall the details. If I were so motivated, I could just finish the software side. I think almost everything else worked. If I recall correctly, I wasn’t happily with this one because it won’t dial down below something like 1.5 volts. I’ll share another incomplete power supply later that is even more complex and never finished. I have a thing for doing stupid complex stuff that I don’t finish. Before I was disabled, I finished stuff; still complex, but very different kinds of projects, mostly car stuff.
