IR Flood Light
I finished soldering together a 36 LED array of 850nm IR LEDs at 50 degrees viewing. It is a kit found on BGMicro.
As suggested by Dale Wheat, solder each piece at a time, and trim each row before the next. I would suggest starting from the middle row and working your way outwards, for added space; and make sure all connections are solid!
My goal is to use this in a diffused illumination multitouch device.
Notice the negative lead has printed dashes, it took me a little while to find out which was for negative/positive without using a voltmeter– I was afraid swapping the leads would fry something! Anyways, I do suggest a voltmeter.
The charger comes from an external maxtor hdd. Had I more time I would have tried to keep the end connector to preserve the use of the charger, but no matter I have a few laying around. The final pic is lighting up the sony cybershot dsc-w55 camera, which does not fully block IR light it seems.
