All:
I've been wanting to try a new technique for making PCB's but never got around to it until now. The first time heard about it was via a series of YouTube videos by Charles Adams, K7QO. He calls this technique the?

Muppet method because it's a mix of Manhattan and Ugly construction techniques. Simply stated, you use ExpressPCB (free download) to create a circuit board. Once that's done, you create a negative, flipped, image of it and send that image to a laser printer using color laser paper. (If you don't have a laser printer, put the images on a thumb drive and go to Staples and have it printed.) Next, he laminates the image to the copper side of a PCB. I found an Instructable that uses Isoproply Alcohol and Acetone to transfer the image to the copper. It takes about 5 minutes to etch a small board. I've posted two pictures of the resulting board; one just after etching and the second with the parts mounted on it.
I'm thinking of writing an article on it and will share it if there is interest.
