Cheap and good PCB etching solution..... 2010-01-03

The etching solution is made by adding 1 part Muriatic Acid (the common kind that's sold in hardware stores, about $5.00 gal.) to 2 parts Hydrogen Peroxide (the common 3% kind that's sold in dollar stores & drugstores for $0.50 a pint)

Warning!!!!!!!!
Mixing is a hazardous process (add acid to the peroxide, not the other way around!)

The board pictured below was etched in five minutes at room temp.

Question: To save Press-n-Peel someone talked about taping it to a regular sheet of paper. I have been reluctant to feed tape through my laser jet. Any comments?
