Well i had invented the mechanical SSTV glow paint monitor .
The idea was to copy the result of the p7 crt used in th early days of SSTV to view pictures scanned on this long phosphor persistence CRT,but do it mechanically and with junk box parts .

I am not sure if you can view the pictures and odd video if your not a member of the other forum but this is the link to my project.
How its done and how i came to getting it to work was a long process the idea was right but i needed to get my head around the correct scanning and how to modulate the laser .
Ok the drum is painted in Glow paint i found the type shown in the last few posts was much better than what i started with as its finer the first type i used was grainy so not great for fine detail.
I used a Uv laser to charge the glow paint the amount of time the paint is charged will glow depends on the intensity of the laser ,think i used a 20mw but all that power is not needed.
IT was a great project and i am proud i got it to work my very own invention.
