My serial LCD for displaying directions
bioart:
I took a USB cable and identified the +5 and ground (red and black on mine, but used a voltmeter anyways). I spliced that cable into a dvd digital out cable that fits perfectly into the power header on the lcd. Now the LCD usb powered :)
I emailed the guy selling the backlight many times, but have never gotten a response... what else do I need if I buy the EL sheet?
I started working on my app to drive it, and it may become a full featured FE... we'll see :P
TheGatesofBill:
You'd need an EL sheet, and EL inverter, and a pair of scissors.

Ah, cool, I didn't look close enough to realize that was all it would take. Thanks for the tip.

Yeah, check this post:

If you hold the LCD Vertical with the contrast lever up they would be the two bottom pins, right side being ground, left side being current.

You can use a small 2 pin molex connector to wire it up. Your best bet is to use an IPAQ (though I don't know how) or to wire it directly to one of the device power leads from the pc (5 volt & ground)

BTW, the techknowman site you were referring to earlier (http://www.techknowman.com/Kits/Kits.htm) took my order for a backlight so he must still be around, I got an email from him today and paypalled the total cost ($42 for the kit w/ usps shipping). So he definintely is around, although it looks like he is almost out of kits (said 5 left when I ordered). Just thought I would mention this for everyone looking for backlights on these LCDs.
