I got some small cathode neon light bulbs off ebay and want to use them in a case mod. The sell says I need to hook them up at 120vdc at very low current. What would I need to get that out of a Computers PS?
An ac inverter - to step the 12v dc from your psu to 120v ac to power the lights i suspect. If so, an inverter suitable for an electroluminescent LCD backlight, would probably surfice. BTW: aren't those 2$ bills as rare as hens teeth?
no, in fact i have 2 sitting on my desk as i type this, one is a 1995 and the other one is 19 sixty something, its really crumpled up...
Doh! I just noticed that when I re-read the topic title! Sorry! Only thing I can think of is some sort of step up transformer then...
With neons you get the glow at the negative electrode, so if it's shaped as a reflector that makes sense. A diode or bridge rectifier on the CCFL inverter output would give you DC, but don't blame me if you blow the bulb or the inverter.
try www.allelectronics.com part number ex-38 It says that a 6V DC supply gives you 90VDC So maybe 9 or 12V should give you what you want
with cpemma on this, a bridge rectifier on a ccfl invertor, dont forget though that the dv from thet will be ~1.41 * as much as the ac out. Col same disclamer as above
