  1. Charlie, Thanks so much for the info and link. I was wondering what the white powder was! Best, Michael
  2. Hi, I'm currently restoring an old DeVry Portable 35mm projector, very similar to this model http://filmprojectors.eu/images/PortableMovieProjectorDeVRYPORTABLEC90.jpg However there are some very old electrical components and I'm struggling to figure what exactly a specific piece is. See attached. There are two of these in the projector. One of them intercepts the bulb, the other one, the motor. The skinny pole at one end can be pulled up and down causing the disc to slide making contact on each little square. I have a feeling one might control the brightness of the bulb and the other one the speed of the motor (framerate). Any ideas?! Thanks in advance, Michael
  3. Thanks to all. A Bronica 6x6 75mm lens is now temporarily mounted and infinity is showing up very well on tracing paper. Fun, next is to try and run a couple seconds of b/w through. Will keep you posted.
  4. Hi, I recently picked up a 35mm hand-crank 'prism shutter (8sided) and I'm hoping to construct a simple 35mm camera. I generally work with destroying celluloid images, hand processing, vintage tech so I suppose for me any image is a good image. I'm not looking for complete perfection just some nice effects. The shutter http://cgi.ebay.ie/ws/eBayISAPI.dll?ViewItem&item=180702168485&ssPageName=STRK:MEWNX:IT I've recently looked into the 'prism shutter' and have discovered its use mainly in high speed cameras. http://www.photosonics.com/35mm_4bc_psi.htm I'm wondering if anyone could possibly elaborate on the technicalities involved in the workings of such technology along with any additional parts that maybe required. It's very difficult to find any such info. Regards, Michael
