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

I have better solution. Use PC Power Supply. BLACK = GND (black), BROWN = 5V (red), RED = 12V (yellow). You can use only 12V and regulate it with 7805 regulator to 5V. :-) Have a nice day.

I know, this theme is old.

Step 2 = REALLY confusing.

Punctuation please.
Even limiting capitol letters to the first word in each sentence would help.

Perhaps a simple schematic?

If I read it right(probably NOT)
Then Orange=N/C, Red=3V+, Black=6V-, and brown = common?

i think so i just was board one day i didnt know how to get it working so i figured i would have fun blowing it up and with random luck i got it working im sorry its not that clear but i dont have enough money to get a better camera i dont have a job and its hard for me to get the parts to do things but thanks for the concern

no worries.. it's not the images that are unclear. it's the WORDS ;-( "step 2 : Step One" I THINK it should read 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. I've added an image I THINK shows what you did. Corrections would be helpful :-)

thats correct

try adding a solar charger to charge the batterys

[newtylerjh]

sorry dont have one

I'd REALLY really REALLY like that step 2 cleared up. I now have 2 of the 2-lead inverter circuits(12V) from 2 discarded scsi scanners... and one 12V inverter i actually BOUGHT(American Science and Surplus was having a sale). But, for a while now, I've been saving a few complete sets(bulbs+inverters) with the extra-wire style power input. It'd be nice to be able to re-use these in future projects too! Plus, I can get new sets free, fairly readily, as other modders don't have the patience or know-how(yet) to implement them simply. They'll just give them to me, already stripped from the scanner... on account of not being the simpler 2-wire models.

will do thanks for your input
