It's always another option and if it allows people like Harry and Troy to see some of your camera output I am sure it will be a great incentive to them. I wish I had kept all my old stuff on tape but - oh well...

I'll dig out some of the old software and associated picture files and post them.
I might even take a few pix of the disc camera...
Cheers,

Troy, in my best Mythbusters accent - "well there's your problem" - the photosensor is infrared! All the visible light spectrum will be severely attenuated.
LDRs and solar cells have both been used in the past (as have phototransistors but not IR versions) with varying degrees of success. In particular I have had good success with solar cells but that was back in the era of monolithic solar cells - these days they tend to be broken up into cells which cause problems if your image flass over 2 or more adjacent cells - an area for experiment however. The other problems one can have with them is response time and visible spectrum limitations.
Troy the dome cells can be bought from the club shop through Vic Brown - you would need to be a member however - something I would very much recommend anyway. As far as I am aware there is no other known source.
Troy, in the meantime, I have a spare dome cell I can send to you - PM me with your address and I'll post it to you.
PS: With your current rig you might want to try and replicate Baird's "night vision" experiments - break out your old radiator heater as a source! - LOL (or use an IR LED light source).
BTW - I am not sure I have already mentioned this but you would also be well advised to record the output of your head amp via a sound card on your PC/laptop - that way it is easier for you and others here to analyse the quality of the signal.

I think the disc might not be spinning fast enough as I'm not getting intelligible display on your program nor am able to sync it for an intelligible display of a light.
