A great video about DIY photo etching PCB produced by jollino. This is a photo-etching walkthrough to show how I make my own printed circuit boards (PCB) at home.
He uses Eagle in order to design the PCB layout. Everything is designed in reverse and does a test print on regular paper to be sure that it can print all the components. One tip is to use the darkest black color when printing.
Very good PCB site
Great video and i love your uv exposure unit from an old scanner.I do have one safty improvement you could use a micro momenarty switch under the lid to only switch on the tubes when the lid is down.
