Cory Doctorow at Boing Boing, with an excerpt from Chris Shen explaining the Infra:
The main change to the Peggy was to solder molex headers instead of LEDs: this is to allow the wires to be easily plugged in and out of the board which is necessary when dismantling and reassembling the piece. Yes, all 625 remotes are numbered so they can be removed from the frame for transportation! The current and voltage was also adjusted fo IR LEDs as opposed to visible LEDs.
While researching, the main thing I was looking for was the ability to play video (live) on a low-res matrix. I looked into various ways of doing this but once I found the Peggy 2 kit it gave me confidence to go ahead with building Infra because of the open-source nature, existing work done by Windell, and Jay Clegg’s video Peggy mod.
This is one of those cases where I feel like someone is almost too smart. This is some pretty incredible stuff. Making a working TV-type-thing out of old remotes? Say what?
