Bit of a clean up worth the effort to finish that one off ,she'll be a beauty for sure .
I did experiment with a flying spot idea some years ago, without success, maybe one day I'll have another go...maybe.
Many ways to go on this ...scanner or the 2 forms for camera direct flying spot could be electronic CRT scanning a slide then moving on to a photo pretty much have a direct light camera then just have to play with the optics .
I'll knock-up a sketch of the concept and add it here later...at 33.3RPM it will take about 3m 50s to do a 128-line scan! Sit very still for your close-up!
I love the idea of using a turntable to get the line scan rest is easy ,do sketch up your idea turn table for this very interesting .
As you might expect from me the 'mechanics' are as simple as downright possible!
I think your planning a direct light camera my down fall when i tried to turn the scanner into this was i never took into account it needs to be in a light proof case only light via the the lens ..mechanically i was there had some close up results never got to a fair distance image ...live and learn
viewtopic.php?f=23&t=1890&start=135A hint, I often give my projects a silly name, this one is 'Noddy'..though no connection to 'Big Ears'...
Oh that's like how i would envision it working with that Name ...i will wait to see !

...don't forget Harry, I lived not that far from you in the 70s...less the 60km south...hence the occasional Strine slips in!

We talk like that to keep the fly's out of our mouths ..so i blame the fly's for this form of English ! I should think your neck of the woods it would come in handy for the same reason they like the heat the fly's .
Getting back to this project i just started on the decoupling caps on the power supply few more to go didn't have much time today takes me half the day to mow the yard so only got a few in this afternoon,i will move on to decoupling caps on the crystal oscillator i had them on before but removed to place them neater this time .i can move onto the rest of it .
Any more thoughts on IC102 Steve as in to be used or not ..i am not sure if i should solder a socket in .
Edit
I found i had a heap of what i think are tantalum capacitors 100N due to room and keeping it neater i have replaced the ceramic.
The electromagnetic spectrum has no theoretical limit at either end. If all the mass/energy in the Universe is considered a 'limit', then that would be the only real theoretical limit to the maximum frequency attainable.
