[dorkbotnyc-blabber] pcb etching supplies

[Michael Ang]

I've found that "photo basic gloss" paper from Staples (item #471861) works 
pretty well.  It's a bit of a pain to get the paper off once you've ironed 
it to the board though (lots of scrubbing).

One fun thing to do is to use copper sheet instead of copper clad board. 
You can make circuit traces that are flexible and use them to e.g. to make 
3D forms.  The basic process is the same as making PCBs.  Soldering can be 
a little tricky since the heat transfers away fast, but it works.  Some
