Smart, but the more sides the mirror has, the smaller the projection range gets, but I don't need much of one anyway. Do you have any idea of what kind of a motor I can use to get the high rotation rates that are required? With an octagonal mirror I'll still need 120 scanlines x 25 FPS = 375 complete spins per second. I got this idea for avoiding flicker, if there's such a thing as a material that lights up when hit by IR light (I think there is so): If you replace the LED with an IR diode/low-power laser, and replace the white, partially transparent surface with something that lights up when hit by IR light, you'd have the perfect flicker remover. I'm sure that the material probably doesn't react to light too fast, so when one retrace is finished, the image will simply stay around until the next retrace comes. Voila! No flicker! I'm also thinking about the possibility of "gearing" the electromotor driving the mirror up to a reasonable speed. Is this possible without frying the electromotor? By the way, won't the octagonal shape of the spinning mirror do wonders for aerodynamics? I mean, at the speeds we're talking about, wouldn't the two-sided mirror be like a flat, big sign in a winter storm (of course, the mirror wouldn't blow down, it would just slow down I'm still thinking about how synchronization is going to work. With all these lights and mirrors, there has to be some means of detecting when the next scanline is going to be around. As for space problems, I don't see exactly why. Just make it all in a reasonably small scale. :) -- Thor`n -- Subcription/unsubscription/info requests: send e-mail with subject of "subscribe", "unsubscribe", or "info" toWear-Hard Mailing List Archive (searchable): http://wearables.blu.org
