I’ve kind of been obsessed with trying to make circuit boards on my laser cutter since I got it. Other people had already done this by using spray paint as resist – then laser-etching the paint off non-trace portions of the board. This process still requires chemical etching – which I’ve been trying to avoid.
I had some success several months ago – making crude PCBs by laser cutting thin steel – but those boards aren’t good enough for surface mount components or anything complicated.
So – if I can’t make good boards without chemical etching – I figured maybe I could use chemicals in conjunction with the laser cutter to make some decent 2-layer boards.
After a few failures – I came up with the process documented in the video. It works pretty well! I suspect if streamlined a bit – you could go from Eagle to working board in under 90 minutes.
Stop breadboarding and soldering – start making immediately! Adafruit’s Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and more. Build projects with Circuit Playground in a few minutes with the drag-and-drop MakeCode programming site, learn computer science using the CS Discoveries class on code.org, jump into CircuitPython to learn Python and hardware together, or even use Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for MakeCode, CircuitPython, and Arduino. It has a powerful processor, 10 NeoPixels, mini speaker, InfraRed receive and transmit, two buttons, a switch, 14 alligator clip pads, and lots of sensors: capacitive touch, IR proximity, temperature, light, motion and sound. A whole wide world of electronics and coding is waiting for you, and it fits in the palm of your hand.
