Introduction: How to Turn That Old Scannner Into a Portable Emergency Light
In This Instructable I'm Going To Show You How To Turn That Useless Old Scanner Into A Useful Lamp I Built Mine Out Of Some Parts I Had Kicking Around But You Can Just As Easily Go Out And buy The Parts
Step 1: Needed Parts and Tools
For This You Will Need
A Scanner Carriage
A 4 Cell AA Battery holder
A 2 Cell AA Battery Holder
A Soldering Iron With Rosin Core Solder
A Screw Driver (Both Phillips And Flathead)
Wire Cutters And Strippers
Double Sided Tape
And Some wire
Step 2: Step One
The scanner carriage I chose has two lamps and four wire inputs coded Red Black Brown And Orange. The Black wire on the carriage goes to the negative terminal on the four cell battery holder. The negative terminal on the 2 cell battery holder goes to the positive terminal on the 4 cell battery holder. Then the positive terminal on the 2 cell battery holder to the red wire on the circuit board for the lamp. The brown wire on the board goes to the positive terminal on the 4 cell battery holder and the negative terminal on the 2 cell battery holder. Leave the orange wire alone.

Now that I've read it in the daylight hours... I think your setup is supplying 6 volt through the black-brown circuit and 9 volt through the black-red circuit, and 3 volt into the brown-red circuit.
