MiniPOV using UV LED's

[DJ4MC]

I just built another MiniPOV kit but used UV Led's that I got here :http://www.dealextreme.com/details.dx/sku.2398 and it rocks. I slowed the display down by changing the timer prescaler to this:
TCCR1B = (1 << WGM12) | TIMER1_PRESCALE_64;
OCR1A = (uint16_t)10000;

And it let me "paint" the text as it appeared onto a glow in the dark surface. I'm planning to expand this and use a stepper motor to move it in a circle. around a glow in the dark disk. I'll try and get some photo's. I need to boost the current for the LED's. I'm actually suprised they come on with two AA batteries powering the whole thing.

Thanks Lady Ada! Great Kit.

this seems to be surprisingly popular. we even saw a 'product' that does this on some site (one led, not POV)!

Here's a video of just the thing.

LOL that is what caused me to want to build one! The challenge is the different kinds of GITD paint out there. I'm going to find me a yard sale turntable and wall mount it sideways
