This sign was made almost completely out of an old scanner - pulled from a Stanford dumpster on move out day.
I got a great compliment on this project - I was told that we'd have to get more nice things to go along with the sign. Amazing, as this thing is made from a derelict scanner,some scrap plastic, a bit of grubby scrap paper and hot glue.
Step 1: Parts
- CCFL Bulb - preferably in it's holder assembly
- CCFL inverter - will have some wire going in, and some high voltage wire going out (to the bulb)
- Power Supply
The bulb will be on the scanner carrier along with the scanner CCD. It's likely to be in a plastic housing. The inverter will be close by too.
The power supply will be a little more tricky. You'll need to determine how much power your inverter requires. It may be printed on the inverter - or not. In this case, it was not. First, I tried 12 volts - any 12V source will work. This resulted in a half lit bulb - the center of which being dark. Then, I tried the 30V power supplied that came with the printer. Voila, it worked.
Step 2: Signage
In order to get the full effect from the light, you'll need to have your sign raised away from the light source. I used a bit of scrap found in the dead scanner carcass.
Step 3: Solder
It's a good idea to encase your good solder joints with hot glue.
Step 4: Assembly
Finally, glue your assembled sign to the risers.
