when I get like this I dive into a long list of youtube channels that tweak the inner electronics nerd in me ... haven't a hope of doing any of this with any competence (even though I did attend a few years of an engineering degree) but this ... this seems right https://www.youtube.com/watch?v=8Qw6uUh01ck
tbh mine are mostly people doing problem diagnosis and fault-finding on old tech, mostly early 8-bit micro electronics but also in some cases engines/hydrolic systems and/or telephone exchanges ... :)
