[Noisebridge-discuss] light show volunteer?

[jim]

    Thanks for your reply. Seems right to me. 

    Also maybe LED types per chemistry, light temperature, 
heat temperature, lumens per watt, electro-mechanical form 
factors and availability, ways to vary light temperature 
and brightness, applications for red- and for green- and 
for blue-only LEDs. 
    Maybe also various LED drivers (light engines and 
otherwise), availability and near-future trends. 
    Maybe cheap hacks (interesting things to do with 
strings of LED Xmas lights), good tools, best practices, 
how to adapt to 12VDC and 120VAC and maybe 240VAC (for 
other nations' electrical grids), solar panel outputs 
control interfaces (audio systems, light sensors...)?

The idea is that you just hook them up to standard AC and they work, so I don't pay much attention to that. Of course some people call any integrated LED module an LED engine, and there are a lot of new LED pixels coming out in recent months. They're good enough that I'm not sad they're making some of my products obsolete ;)
