Microscope

Thanks to Karsten Nohl presentation at Hacker Space Fest, there's an interesting DIY approach for reverse engineering.

These are the features we're looking for:

500x magnification
2 MP to 8 MP camera
Objective table to move the chip slowly (i.e. not by hand, too much shaking and imprecision)
Reflected (incident) lighting

Feature we DON'T NEED:

Confocal microscope (it seems, because we'll abrase/grind away the upper layers anyway and the bottom layers are opaque anyway too)

Friend of Phil will lend a microscope with camera
- not perfect but should enable us to do the first etching/abrasive steps
Ebay? No perfect match yet.
