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.
My first project is a demo board for the ATtiny43u - a nifty little microcontroller that uses a voltage booster to run on as little as 0.7 volts. The booster can even power small external devices requiring a higher voltage - like an LED.
