Firefly LED light wand! I want to make one.

There is an LED toy that I want to recreate. It was the length of an umbrella, without the canopy, and looked like the person was being followed by a bobbing, waving band of fireflies. Details inside. [more inside]

Help me assemble the parts for an LED ribbon lighting system

I'm trying to determine what parts I need to bring LED lighting to my home. I'd like to install some lights in multiple rooms to be controlled by wall switches and my phone and my network. But I'd like to do it in stages to reduce cost. [more inside]

Are CFL and LED lights safe for indoors (in flush mounts)?

I am getting conflicting opinions on when you can (and can’t use) CFL and LED lights indoors, especially with a flush mount light fixture. I am more confused now that ever. If someone can offer some insight, it would be great. [more inside]

Electronic Catan

I want to create a customized Settlers of Catan board. For the purposes of this question, it could also be a custom Monopoly board. I want the pieces ( cities / hotels ) to light up when they are placed on the board. I know I would put LED's in each piece, but besides that, I am not sure if or how I could power up the LED's. I am not an electrical engineer, but magnets, watch batteries or inductive charging sound good to me. Help me make an awesome electronic board game!

How is this color-changing LED array being driven?

Electronics/LED Folks: I bought a few cheap, poorly-assembled LED color-changing orb-things and I'm pretty sure they're the coolest objects I have ever owned. I cracked 'em open, and damned if I know what is going on in there, but it looks simple/cheap as all hell. Help me figure it out, I'll post a build-log/parts list somewhere, and in short-order we can all be ass-deep in home-made, disarmingly sublime mood-lighting. [more inside]

Simple, small, cheap accelerometer/LED?
