El Wire / Power Question
milhouse:
I just ordered some El Wire to play around with, possibly to use on my control panel. It runs off a battery back containing 2 AA batteries. I'd like to run it off 5V from my computer. Can anyone tell me the type or circuit I'd need to use? I am guessing its just a matter of installing the right resistor, but I'm not sure of the calculation.
Thanks.
VanillaGorilla:
AA batteries output voltage varies based on composition. Alkaline produce 1.5 volts. Lithiums are 3v, and Li-Ion rechargables about 3.6 volts. If its running off of 2 aa batteries now you are producing between 3-7.2 volts output. Have you tried just hooking up 5v to see how it reacts?
milhouse:
I don't have it yet. I am just concerned it will act like an LED and "pop" if I provide too much voltage. Is there a fundamental difference in el wire where that isn't an issue?
Thanks.

You might be able to pick up a USB inverter on eBay. I have one of those battery pack EL wires setups for a costume I am building for my daughter, but once she's done with it I might repurpose it for my own use. The USB inverter might be the way to go.

I was gonna suggest the USB inverter also. They can be had for 5-7 bucks, if you're in the US...
