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)?
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!!!!
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.
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,
Looks cool! How many colors on each RGB LED? I think there is only 8 color combinations, since you are using 595 without PWM. Do you have an English web page for this?
So there are only 42 updates per turn? With only (32*3*42=4032 bits per turn = 504 bytes per turn. With only 4032 bits per turn, the video looks very high quality. A 64M EEPROM can hold 16 frames of image with this arrangement. Am I right?
After that i made the current version with a MMC card. This has 16Mbyte. This can have up to 32000 picture. The video on it is about 750 pictures. If a picture is steady for a while then this is only one picture and the number of turn displaying this picture is a variable in the picture data. (byte 505)

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

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)

this is beautifull !! please tell me what kind of PIC controller do you use is it a 16f648a or 18f4550

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

Indeed there are only 7 colors (plus 1 for black which is no color). I don't have an english webpage. Sorry for that.

sorry it should be 64k instead of 64M. With 64M of EEPROM, you can put 160 images.

16000

This is right.
504 bytes per turn.
an 8kbyte(64kbit) eeprom holds 16 pictures.
This was my first version.
After that i made the current version with a MMC card. This has 16Mbyte. This can have up to 32000 picture. The video on it is about 750 pictures. If a picture is steady for a while then this is only one picture and the number of turn displaying this picture is a variable in the picture data. (byte 505)
