Introduction: RGB LED Moodlight in 10 Minutes!
Here is my 2nd. Instructable. A very quick one! ;-)
I will show you how to build a nice 3-RGB-LED mood light in nearly 10 minutes.
What did you need?
- battery powered LED touch-light
- slow rainbow effect RGB LEDs with slow automatic color cycling (or fast if you like ;-)
- small screw driver (depends on your LED touch-light)
Step 1: Look What Is Inside the Touch-light
First I remove the batteries from the bottom side of the lamp.
With my fingernails I can grip between the upper silver and the lower black part and simply lifting it up.
Then the rest of the parts dissolve them self. Really cheap build lamp ;-).
On the 3rd picture you can see the small PCB with 3 white LEDs and in the switch in the middle.
Step 2: Heat Up the Iron
Now you should remove the 3 LEDs with your soldering iron.
Then replace the three LEDs with the rainbow LEDs.
Don't forget that the long legs of the LEDs are the anode pins. They have to connect to the positive voltage.
Step 3: Test and Rebuild
Now insert the batteries for a quick test and then rebuild the parts.
If you like it you can place the semitransparent paper between the reflector and the glass for a smoother light.
If you switch the light on all 3 LEDs starting with the same color. But with the time they drift to different colors because of their tolerances.
Thats it. Have fun with it!
PS: don't forget to switch off the soldering iron ;-)
