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]
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]
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]
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!
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]
I'm looking for a simple, small and cheap way of measuring acceleration. Basically, I want to make a set of LEDs light up if they are accelerated significantly, becoming brighter the faster the acceleration happens. [more inside]

I want to learn how to make simple electronics, like LED controllers that I can hook up to a serial port. Can anyone recommend a book to get started with? [more inside] [more inside]
