I started back this spring with very little electronics knowledge, it’s a fun entry-point into it! I’d say first would be find the circuit that speaks to you. I’ve tried a handful but the books haven’t work for me (yet), there’s too much hard math and they don’t make weird noises and I eventually just give up on em. I more just google when there’s something I don’t understand and treat the stuff I can’t understand yet as mystical, and then annoy smart people on forums such as this one with questions, it has worked so far lol.
@mlogger has a list in his trade thread for pcb with some quick descriptions (I believe @crucFX has done some more pcb conversions recently…not sure if there’s a list somewhere)
https://llllllll.co/t/fs-ww-ciat-lonbarde-paper-circuits-pcbs/23342
and then search for them on youtube to get an idea of the kinds of sounds they do.
Then, once you have the one(s) you want to do…find the paper circuit file (or a pcb someone has made of them) and start determining the components you need.
There is a master legend list of (most) of what the symbols stand for, and each of the paper circuit printouts on the cl site usually has some info about a handful of them (so it’s a bit like a scavenger hunt as you look through all of them to learn little tidbits of peter’s code). Make sure to search here to see if there are cool mods people have found, hairy cap and x resistor values, etc.
Once you get your list of stuff together you need, you can get nearly everything from tayda which is like if radioshack still existed (or digikey/mouser which has four billion of everything), save for a couple discontinued parts that you can gamble with on ebay sellers or find comparable parts/smd versions and PDIP -> SOIC adapters.
As I’ve started to understand more, this circuit simulator tool has been extremely helpful in “testing out” ideas, as have breadboards. https://www.falstad.com/circuit/circuitjs.html
