"AndyW" wrote in message ... (but then I enjoy retro-tech like making Baird televisors) Mirror-drum, or Nipkow disk? Nipow disk. I built my first one while at school using plans in Hobby Electronics using my sister's 'The Partridge Family Album' LP, I thought that it was the best use that it could be put to; she disagreed. One of my later ones used a 'conveyer belt' instead of a disk which produces a square screen. LED or nitro-benzine as the polariser? Polariser? I used a neon as my light source, I didn't have any polarisation. My later ones use LEDs at light sources and produce a much better quality of image. Andy |
