I recently had a batch of 10 pcb’s for an ongoing project fabricated with iteadstudio pcb prototyping service. They guarantee 100% electrical test on their product page.

I wasn’t particularly checking for the e-test, I was more interested in seeing if the small pads and vias look good. I was however surprised when I did not find the small marks on each pad which are a good indicator if the e-test has been performed or not.

This circuit is how [John Tsiombikas] makes his cheap 3D shutter glasses work with a Linux machine . It’s not that they were incompatible with Linux. The issue is that only certain video cards have the stereo port necessary to drive the head-mounted hardware. Shutter glasses block light from one eye at a time, so that different renderings can be shown to create the stereoscopic effect. Since stimulating the muscles in the eye doesn’t actually work , you need to find a way to drive the glasses in perfect time with the video signal.
