Long time no see.
I've added a picture of a system's design of Stu-PD's prototype. I have someone who might be interested in getting this project funding so I might actually get something done.
I'm in a bit of a difficult position with the whole pandemic going on so practically all my projects have been halted. I'm seeking to doing something about that first before I can even think of doing StuPD.
Thanks for checking though! Stay safe and have fun hacking.
