reusing scanner lamp w/o heavy duty adapter? Answered
I've been trying to do something similar to these
I want the lamp to work without a heavy duty ac to dc adapter, but it looks like there's no practical power cord that has low enough voltage. I've tried using a basic voltage converter ( http://www.amazon.com/VX-79NP-MULTI-PURPOSE-CONVERTER-MULTIPLE/dp/B0014JUGTQ/ref=sr_1_20?ie=UTF8&s=electronics&qid=1209273618&sr=1-20 ) set at 12 volts, but the bulbs don't light.
Does anyone know if there's a way to do this without the giant adapter, or if there's a way to light the bulbs using a USB connection? I've looked online, and the only thing I've seen is this: http://www.danielandrade.net/2005/12/27/howto-using-the-scanner-light-inside-your-computer/ but they're using a male molex connection. I'm just looking for a plug that's a little more practical: an electrical outlet being my first choice, a usb port being my second.
