Introduction: Perpetual Ball Roller

This machine is controlled by a PicAxe Microcontroller. A servo (used for steering in R/C cars) is used to tilt the track for a ball to roll round. The degree of the tilt can be controlled by a potentiometer in manual mode or in automatic mode preset instructions on the microcontroller tell the servo how to move.

You can find more about it on this website along with the code for the Picaxe microcontroller.

    I like this as a project and would like to make one, however, it isn't a good example of an instructable without all the information available to enable you to make make it.

    The link with the picaxe code no longer works.

    I'm not sure what you mean, I sent a link that works (for pictures and the code) and explained I don't have a schematic (circuit diagram).

    Sorry, I no longer have it and I didn't bother making a schematic. It's just the standard 8M picaxe download circuit with a servo and pot attached. the code will define which pins to use. if you are not familiar with picaxe just use your favourite microcontroller, it's a very simple project that doesn't require any special libraries.

    This NASCAR style track is interesting, But I would like to see something more on the lines of a Formula One track.

    What about having something like a circle of sandpaper that has ball bearing on top of it, and a track like the one you have here on top of them to keep them in place. Then resting on top and being guided by the track you have some flat object. The sandpaper is rotated by the micro controller which uses friction to spin the ball bearings in place, all in the same direction, which causes the flat object to move round and round the track. I thought it would be cool to see something that's not rounded, and therefore would normally be stationary, drive around in circles.

    I can half understand what you're suggesting but it's a tricky one to visualise! One day I'll mess around we this concept. People have given me a bunch of ideas for it but unfortunately there has always been something else to do!
