Hah, no. It has three LEDs in parallel, not a camera.
So, it effectively acts like a single pixel, and can only sense a single pixel worth of information. Itāll have to talk in blink patterns instead of QR codes. And since the screen can be just about anything, itāll probably be pretty slow in order to make it compatible with a wide range of devices. DEL modified the circuit a bit to make it work, and figured out a way to somewhat amplify and center the signal to improve sensitivity, but itāll still be a pretty slow one-directional data transfer.
Itāll probably be useful for people who build and sell lights, since it could eliminate some of the need for reflashing. For example, it might be possible to configure voltage calibration from a phone. But for most people it seems like more of a gimmicky novelty. And it could easily go too far and make the thing brickable, so it would be a bad idea to put it in receive mode at a disco party.
(Iām planning to give it at least some minimal data verification algorithms, so accidental configuration should be unlikely, but itās not exactly going to crypto-sign and checksum each transaction)
Hahaha TK, āmy FW3A is acting weird, LVP kicks in at 4V and I have only 1 modeā , all baffled only to discover it was a disco party the night before
So Iāve been wondering (and I canāt seem to find it in the thread using search) but how is the internal tube for the switchās signal insulated from the main tube?
