RE. Re. Xenon DEATH FLASH!!!!!
It is intriguing to note that I have observed this effect on rectangular RGB LEDs as well (tested just now) - if you shine a bright continuous wave infrared source into the LED the sequence is affected and in some cases stalled because presumably the red LED is sending voltage back into the chip and screwing with the timing.
Also worth noting that these can be synced up using power fluctuations as well and the xenon flash effect sometimes occurs with programmable LEDs such as the WS281x although I haven't tried it yet.
Time until someone uses this to make a "synchronized green LED throwie" effect in time for St Patricks Day .. 3..2..1..
Biting the hand that feeds IT
