We have for a longer time dreamed about a project where we throw a beam of light to the wall. Now the LED-lasers have come down in price and PIC has made possible a rather simple design. We would like to use old HP Laserjet writing heads for it. (yes, I know that the laser in the writer is unvisible, but we will use only the optics) Now I don't find anywhere schemas of the motor driver TOSHIBA TA7259P that is sitting in the writing head. A schema of the head or the connector in the head would be nice too ! Toshiba's WWW-pages are aesthetically nice but totally useless. (I did some lab work with He-Ne-lasers and mirrors clued to bass loudspeakes and got nice results when VIC20 was state-of-the-art) -------------------------------------------------------------------------- PTM, pasi.mustalahti@utu.fi, ptmusta@utu.fi, http://www.utu.fi/~ptmusta Lab.ins.
