I was very impressed by the videos so just ordered two sets of these:
But does anyone have any idea what the technology behind this is? Clearly the RGB LEDs are each individually addressable/controllable but apparently the entire thing is done on a 3 strand cable in which two of the wires must presumably be power and ground. So what's going on with the 3rd wire? Is this just like strings of WS2812 and so it's just one long serial shift register? Or is there something else to this?
Clearly the real "clever bit" is using the phone camera to detect the physical position of every light during "mapping" and then light it at the right point in the timing sequence to show the various patterns/text/pictures etc. during playback.
I just wonder how feasible it is to do something like this one's self ? So far I can't find anything that will admit to how they've actually implemented this.
Or to put it another way, does anyone have experience of WS2812 based strips and think this is "do-able" using those?
But the thing is the LEDs in these lights are like individual, stand-alone LEDs, not just elements on a strip:
Also, if that picture from their site is to be believed it even suggests just 2 contacts, not 3 ?!? How can that work - could it really be modulating a power pin or something?
