When I was at school they taught us how to make circuit boards using Letraset, ultraviolet light and an acid bath. (It was completely weird and mysterious to me at the time, I had no concept of why anyone would want to do it). Making a single circuit board or a couple of copies.
I'm assuming nowerdays there's a way to do this more easily - either with some element of digital fabrication at home or sending off to a fab lab of some sort. I wouldn't know what to even search for - is this a thing?
#electronics@grahamdunning It's now so cheap and fast to get boards made to ridiculously high standards that few people make their own. JLCPCB is one popular supplier
It is possible to etch boards with ferric chloride. Blank boards are available with photo resist, and the mask can be printed on a laser printer.
It's also possible to mill the copper from a circuit board using a CNC machine tool, which can be quite small if it's only got to take a sliver of copper from a fibreglass board.

@grahamdunning If you’re in the EU, there’s also @aislerhq
https://aisler.net/@Firesledge @aislerhq great, thanks.

#electronics@grahamdunning We did the acid bath thing too my hazy recollection is that instead of letraset we had some kind of special paint pen to mask out the tracks.

#electronics@grahamdunning i've definitely seen people order custom circuit boards in ones / twos, so i know it's out there.

#electronics@grahamdunning gotta tag @xaxalxe as she makes her own (beautiful) custom PCBs, I'm sure she has a few things to add
(btw Lucía, cyber.nymph.garden seems to be down!) -

@sbszine ah nice!
The only other thing I remember from it was the technician telling us you could use the acid to burn your finger prints off if you wanted to commit some crimes. -

#electronics@grahamdunning in Europe, I've used eurocitcuits.com mostly. And I design in KiCad, which is a fantastic open source software package. By now you can even upload the KiCad files to Eurocircuits, without the need of exporting to Gerber files.

Yeah Kicad is the thing ! I usually get my boards made (and delivered within a week !!) at JLC or PCBWay.
