I got hold of a nifty LED bar graph array identical to the one used in the Shaak Ti/Adi Gallia saber. Rather than just use it purely cosmetically, I'd like to have it actually light up when the saber is on. I know how to wire a simple LED accent light, but this one has 20 pins! Does anyone know how I might do this, assuming, for example, that I'm using a 4aaa battery pack with a Luxeon III and an Ultrasound 2.0? Obviously, I'm going to need a resistor, right? Here's a JPEG of the datasheet:
And here's a link to the original PDF file. The technical information is mostly Greek to me. And for those of you interested in buying it, here it is on mouser.com.
Finally, here's what it looks like on a fan-made replica of the saber hilt:
BTW, does any know who made this? I found the photo on the Lightsaber Archives here. It's beautiful, but I would have polished the brass part and protected it with a sealant. I suppose it's a matter of taste.
It would be extremely cool if I could wire it so that the bar graph reflected the amount of power the Ultrsound board is sending the Luxeon, but I'd be happy just have have all ten LEDs light up while the saber is on.
