Purple Tentacle asked:


I need to sort out some very amateur stage lighting. It’s going to be set up in a large marquee running on a generator, so it has to be very low wattage (so LED).

The controller has to be simple so nothing elaborate. We only want to be able to switch the lights on and off and fade between colours. The users will have very little experience of these things so it has to be basic.

Any ideas?

I work for DOT and frequently assist stranded motorists in my off time. I would like to build my own LED flashing amber/white lighting to improve my vehicle’s visibility on the side of the roadway. Where can I get the components I need to do this? I’d like really bright LED and IC’s that will regulate flashing. Where can I get these?
