[andre] sent in his first attempt at using a HD-DVD laser diode to expose photosensitive resist to create PC boards. We’ve been meaning to give this a shot with the ol’ Epilog laser cutter. For the test, he coated the board with some resist and hand exposed it with the laser. Finally, he etched it with some sodium hydroxide.

Lamination For PC Board Etching
If you’ve ever tried ironing laser printed paper to transfer the toner, you know that it can be slightly frustrating. [Dave] sent in an interesting twist on this method. The laser printer is used to print onto paper from a magazine and then the board and paper are both run through a laminating machine six or seven times. From the writeup, it looks like this technique works great. (You’ll probably need a printer with a manual feed tray to get it to print on the magazine paper)
