DorkbotPDX people doing strange things with electricity

I made a test pattern to determine what my etching capabilities actually are:

This one is a bit better than my last one. It's smaller (2x2 inches vs. 5x4 inches) so you don't waste as much board, has test points, and a bunch more common surface mount components.

My method was:
* Print to magazine paper.
* Transfer to copper using 12 trips through the laminator.
* Etch in a muriatic acid / hydrogen peroxide bath.
* Remove toner with acetone.

Here's the final result:
Board 1:

The 8 mil trace is good!

Board 2:

Only the 10 mil trace and higher are good.
