I made this for a Gadget Gangster project. Not that great now, but updates are on the way.

See here for all information: www.gadgetgangster.com/find-a-project/35-project-by-designer/56-Project-Detail.html?projectnum=200

I have a video, instruction manual, and code. Oh yea, it's also available as a kit.

But you·can·call me micro.

If it's not Parallax then don't even bother.

I have changed my avatar so that I will no longer be confused with others who use generic avatars (and I'm more of a Prop head then a BS2 nut, anyway)

    Here are some of the attachments. Code, How-to guide, picture.

    This project uses the SX chip connected to 8 LEDs to make designs as it spins on the motor soldered to it's base. It pulses them in time to make various patterens.

    Sorry for the problem, Chris.

    So in your spin program, why did you not build a devise and program it to make the flashes in sync with the spinning of the motor? In the video you provided it really has no idea where and when to stop the broadcasting of the letters and symbols.Or should this be done by others to expand on your idea and creation. BTW great write up on building the board but I would have included a socket for the SX chip for those who might not be skilled enough to realize that too much heat will burn this chip up. Great job though..

    If a robot has a screw then it must be romoved and hacked into..

    The instructions state that the GG kit will include a socket and they must solder that in before they insert the chip.

    P.S. It is an SX/B program, not a SPIN program. smile.gif

    I plan to create a similar project with SX chip for my child. Specifically, the POV of a bicycle wheel.
    My humble recommendation is to use Hall effect sensor (very cheap and can be ordered from the Parallax web site) and a magnet as the image <-> motor synchronization.
    Also I think the better way is to use "TABLE DATA" with predefined patterns, so you can easily manipulate with the "display image" (random symbols, words, etc.) in a single routine instead of writing routines for each symbol individually.Instead "pause msec" use Jonny Mac's "DELAY_MS" routine, I think this is a better-cleaner way.

    In attachment you can find what I did a few years ago with BS2 (first test of POV). On the videos you will see "Flickering" caused by bad phone camera.
    Bye

    The thing is that I am not experienced at all with the SX, so I wouldn't know how to correctly modify the code. I am quite better with the Propeller, I only used the SX because of it's small weight, minimum wiring, and small profile.


    By the way, can I copy the bike wheel idea for another Gadget Gangster project? That way I would not have to worry about motor speed and I could use a Propeller. 32k can hold a LOT of patterns/characters!
