Mechanical sstv experiments ...Stage 1
I don't know how far i will get with it but had the idea to try and trying is learning .
Heres what i have done ...i have a tin sort of the right size for the LED write head this will be placed close to the drum which has been coated with glow paint as the LED or led Luxeon is controled down it should write raster lines to the drum as a fax machine would write to a paper around a drum ..
But in this case i am interested in 8 second slow scan television timing the glow it seems to have the right glow time and it should be adjustable to the brightness of the writing led.
Thinking how it would work in my head and how it turns out i need to do the next step which is go past this mock up and mount the drum as and the write led to the old dvd movement arms and do a light test if i get lines as i should i better start doing some electronics for it .
