This is great! Congratulations! In the pictures you published in your site looks like you connected a mmc to the pic rigth away.
do you access the card from the program? you coded in your asm the needed routines to manage the mmc? is the card readable in a pc (standard filesystem)?
Thank you! Happy 2011!

Wow, relly good job!, i'm interesting to built one of those, i have visited your page, but i don't understood, do you have any site with this proyect in english?, i'm very interesting in the way that you was generated 32 * 3 PWM for the 32 LEDs. Can you tell me the way?, I saw that you involved shift register. BRAVO!!!!

Nice, but that's not a ball. It's a cylinder.

That's a stunning project :D, great job!

I like it, if fact I'd like to knowe if it is possible to make something similar to put inside my own products which are plasma lights. check out my videos to see what I mean.

You use a PIC16F628?
You kidding rigth?
How many colors per dot? I looks like 256
Nice Job!!

No it really is a 16F628A @ 20MHz.
All picture info is on the MMC.
The uC only handles timing and data direction.
It is 7 colors( and black) per dot.
1 picture is less then 512 byte (= 1datasector on MMC)

Very good. If you could be kind enough to answer, I have two questions: [1] How many milliseconds for one turn? [2] Doesn't the noise from the commutators give false resets on your micro? --- I made my 1st vers & used commutators, & failed. -- I have a working version using induction 2 transmit power. Although, much lower resolution than yours. My version is on youtube. Search "POV led" if you are interested. I am databus64. Cheers,

1 about 20ms = 3000 RPM
2 noise is not a problem. Use small and large capacitor. For high noise and low noise.
Nice one with the flashing "carlos lives here".
Thanks
