why are we mucking with motors, I saw a set up, where two mirrors were glued onto speakers, so that the mirror tilted when the speaker bounced, two speakers one for horizontal, and one for verticle. by controling the wave form through the speakers you draw with the beam, all you have to do is run scanning waveforms into the speaker, (which is built for high frequency signals) and then synchrosie the blinking of the light. the had part would be syncronising the left right and the up down to each other and to the blinking of the light, but if one controller was outputing all the waveforms? right now Were learning the 68hc11, but its only a 2mhtz chip? so that just barly takes care of 80x25 char 5x7 dots, I ordered a mouser catalog to look for faster parts because the only way i say to do it with HC11'sthrough a serial interface, was to have one chip accept all the incomeing charectors off the serial line and draw the 5x7 font into a video memory, and to have another chip shovel the control singnal out the back as fast as it could, but that saves mucking with gears and spining things, once you align the optics so the laser hits both mirrors, its all electrical engineering? thoughts? thanks sam -- Subcription/unsubscription/info requests: send e-mail with subject of "subscribe", "unsubscribe", or "info" toWear-Hard Mailing List Archive (searchable): http://wearables.blu.org
