Thanks for the kind words!

@wolf yes, been done a few times, but as far as I could tell never quite like this.

@james You assume we have audio :)

Also you are right, (assuming we had audio) routing to the headphone port after decoding the incoming console data would be a nasty job. I decided to do it this way as it was very simple to do, 9 lines of code in the Linux kernel and a chunk in an avr.

Camera flash != cell phone IR-LED

Neat trick, though he probably could have done it easier over the headphone jack — HTC uses a special 11-pin port that looks kind of like mini-B USB, but has additional pins for a headset. I would think it would be easy to find a software modem package, though maybe it’s not trivial to route the system terminal to it.

Yep, this method was on HAD a little while ago.

Cool topic, I think I saw this done to a camera once to dump its firmware via a LED reading USB device. Think it was one of the new cannon’s…
