[Robotgroup] Trail of LEDs

[vkonradi]

I had an idea some time back to make a bunch of nodes which do a regular flash, and which would phase lock to other nodes that they saw flashing, so they would flash in synchronism.  And layer on top of that behaviors like randomly going off on their own flash rate all of a sudden, so as to pull others in the local area along with them.  Make them enjoy cooperating for a while, then they get tired and want to do their own thing, if they see too much conflicting flashing they freak out and break down into their own hysterical spastic flashing, etc.

My original idea was to modulate the LEDs, and possibly an IR LED at the same time, at 38KHz and give each unit an IR remote control receiver to see the others, thus making them relatively immune to interference from other light sources.  Coded up some of this, but never finished the PLL function as I recall.

I have always wanted to do a project that could flash A LOT of LED like
hundreds in some semi coherent way. We would need to build some kind of a
driver card anyone up for it?
