The DIY TK Set-up

Here's the set-up used to digitize the 'California 08' super8 film.

1: Modified Chinon 2000GL projector. Adapted to run slow (around 3 fps with pulsed motor control circuit) also with low voltage cooler-running light source to prevent film burning. A magnet attached to the rotating shutter disc triggers a reed switch every time a frame is stationary in the gate. A hacked mouse circuit provides a USB click to the host PC to trigger capture of each frame.
2: 120mm diameter plano-convex condenser lens to capture aerial image thrown by projector. Lens held in place by home-made foam board mounting.
3: Borrowed Canon XM2 3CCD mini DV camcorder captures images at PAL resolution, connects to host PC via IEEE1394 (Firewire).
4: Host PC (Windows XP) runs Cinecap software. Incoming mouse clicks from projector ensure frame by frame capture to hard disc.

oh.
my.
good.
god.

think you're missing a trick here...i reckon there's probably a way you could make it slightly more complicated if you really put your mind to it.

still, good job though!

Thanks Nick... As it happens, I'm working on a yet more complicated though custom built system at the moment. will post details if version 2.0 ever even looks like working!
