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.
Did you choose components and plan the connections on the perfboard yourself?
Also what was the original like? Would things work if you replace for example the transformer input side either the new kit and keep the output side the same?
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.
