I want to use my stamp to to make a sort of propeller type light
show, just using LED's... I thought about just using a battery and
counter balancing the unit, But then I thought with the speed I need
this to spin at it wouldn't work well. Now if I have 16 led's evenly
spaced all controlled by the stamp, I can properly balance this unit.

My only problem is getting the power from the "Base Station" to the
spinning unit. Does anyone have solutions? I thought about circular
friction contacts, but I was hoping for a component that would solve
my problem.

I hope this all made sense
Any help would be greatly appreciated.

    Hi Eric -

    This doesn't answer your question, but you might find it an interesting
    propeller clock project:
    http://www.bobblick.com/techref/projects/propclock/propclock.html

    The telephone cord un-twisters might work for you at low RPM. I suspect
    even Radio Shack may carry them.

    Regards,

    Bruce Bates

    Hi Eric,
    Try this web site.
    http://www.visi.com/~dc/slipring/index.htm

    I've used this info a couple of times and it works pretty good.

    here is site that manufactures and distributes
    alternatives to sliprings. Their claims are that they
    are superior to sliprings in all aspects, their FAQ is
    pretty nice.
    "The connection is made through a pool of liquid metal
    molecularly bonded to the contact, which provides a
    low resistance, stable connection."
    i looked at a couple briefly, model 331 is 3 conductor
    2@4 amp & 1@30 amp and rpms as high as 1800.
    never used them though because my intended project
    fell through. hope that helps.

    Yeah I saw that Rotary Clock thing By Bob Blick, I was hoping for a
    more "Non Hacked" Approach.


    Best Regards,

    see this page:
    http://www.bobblick.com/techref/projects/hbridge/hbridge.html
    click on 'propellor clock' in the right hand menu. It might be useful.
