Comment on How do I get started designing and making and/or acquiring my own pcb?
blueday@lemmy.world 23 hours agoDefinitely look up a how to. It’s been 15 years since I did this, but you’ll need some photo paper to print the toner on, then use a towel and iron to transfer it to the copper clad cob. Then soak it in some FeCl for 15ish minutes. I just did this outside since it was so quick. Then like a small dremel with pcb sized bits works great for throughholes.

Awesome, yes can just do the chemical outside if volume is small and time is fast. I see there a number of how to, thank you for the inspiration, I will be trying this for sure.

I’m not sure which how-to’s you’ve come across, but my wanderings led me to this guy, who seems to have a very comprehensive video.

Thank you, will check this out.

This is a fine approach too. Just be aware that most modern mcu would be a hell to mount on DIY. Also, this works on literally any paper with super bold print setting.
I would recommend trying copper-based etch, it’s easier to work that FeCl3 (it’s transparent, to begin with, and not as corrosive to other stuff)
Also, I’ve heard some dudes made really nice stencils for paste with some cheap hobby blade CNC tools on cardboard, there are models that have orders of mad higher precision than advertized. Never tried this myself though, lazer cut stainless steel plates from factory are just soooo good (and also a source of high quality steel in a workshop when you don’t need them anymore, they make perfect wood scrapers and such)
