First off get yourself a broken new-ish printer with a scanner. If it is not new you will get a white florescent tube which are cool and useful but we want the led scanners.
-grab some screw drivers/ tools that will get you into the scanner
open the scanner, there are many useful things in here, a stepper motor, glass, and the scanner light.
Locate the light, take it apart untill you access the contacts be careful not to break it
Here is the tricky part.
You have to locate the pins that control the LEDS-
- Typically there will be a positive lead and three leads that control RED, GREEN, and BLUE. The positive terminal is usually on one of the ends, followed by the other 3 (negative) inputes for color.
solder on wires
Have fun! you can mix colors and pulse width modulate them to dim/mix them .
The red seems to draw a different current/ voltage than the green and the blue, iv fried the red at 6v- 0.3 amp
