Picture of RGB Moodlight
This article describes how to make your own mains powered mood light (Also known as led washing light or rainbow light). It is a harmless device which, if used in the way it was meant, can do no harm to anyone. It can give your dark, damp, computerized room a nice glowing tint.

In action:

Step 1: The PCB and other parts

Picture of The PCB and other parts
What will you need:
  • A assembled PCB of the mood light, found here
  • A rain pipe
  • Some kind of light diffusing piece of plastic (i used a small plastic container thingy they give you when you get Chinese food (filled with sambal doh).
  • A big light diffusing bowl, of other fishbowl shaped object. or omit that and just let the light shine on your wall, as a projector.

First make sure you PCB looks something like the picture below.

As you can see i mounted a small PCB with three RGB LEDs at a angle of 90 degrees and mounted the sambalgizmo on that. In the original schematics you wont see it this way, it does require some improvisation. and of course you need to slightly modify the schematic for you led(s). but this should be no problem for a novice geek. As you can see on the pictures, I have already soldered a switch on the pcb and clipped on the power, this was pure for testing and have to be removed later. A tip for building: Test after every step you take, or else you will get really pissed and smash that damn thing against the wall, Really.. Believe me.

Cool idea man, I am in the process of building one similar to yours! :)

Looks like a PS3 move
right like the controls for move

why do u need the rain pipe for

A remote controller can be added to it for 10m away on,off and color changing control

you guys are smart. can i hook up a rgb led in parralel with the different colors suck as: green to red , red to blue . and blue to green pls respond ty.

This is possible, as long as you don't overload the transistors (if used)

It probably would be a good idea, if it flashes like the middle of the video shows, that anyone with epilepsy or suspects they have epilepsy, should probably avoid this. The slow fading shouldn't be a problem though.
i see im not the only one who uses striped CAT5 cable for wire :P

Yeah, it's a component that converts AC to DC
duh.... i don't get it.
AC is the kind of voltage you get from your wall outlets, it varies goes from around 120V to -120V (60 times per second if you live in America, in europe its different) DC is what electronics usually works with, its a constant voltage that has no frequency (it doesnt vary). A rectifier turns the negative part of the wave into a positive and the Capacitor smoothens the wave so you get a DC like thing it can also be made with diodes, (look for bridge rectifier on the web i cant explain everything here), he used a ready-made one, you can also get rectifiers like this one from burnt PC power supplies (if thats not burnt).

Thanks for explaining that :) And indeed, the rectifier did just come out of an old PC-power supply.

You don't get what?

Wickid light man! Probs could find all these components at my school and that, cool! Is there any way of making it have smooth gradients between each light rather than having to turn off then go fade back in?
peterrus (author)  smegger8 years ago
It does just that, as you can see in the movie. Also the original designer of the circuit board has a new version which is programmable. Thanks for the comment and show my pictures if you've built on to!

I just discovered this site and this Instructable as well. Thanks for posting this! I'm going to use this project to light a color organ. Here's a video of a color organ DeLorean!

I am not really sure how you are going to do this, but much succes and thanks alot for the comment!

Very nice project my friend. The colors look really clear, and spread all over. It looks professional.

My bad, fixed that. Thanks for the comment!
