The skull picture is an early test lower line number you can view the 120 line picture at 30 60 or 120 just mirror speed the quality improves with speed of cause.

More of the mechanical Glow drum SSTV only one in the world because i invented it ------

The grainy pictures are the original painted glow drum bad camera does not help but i least i have a record of my experiments the light green drum is the newer type .

I forgot to mention the laser is Pulse width modulated ,there is no need for the geared stepper motor i just used junk i had in hand that was from a junked laser printer .

If you want any more information again just ask perhaps there will be 2 in the world if some one copies it .

Harry,
Thanks for the detailed description.
Your pictures of the scanned images are really
very good. They really show how long the latent
image lasts, after the glow paint has been excited.
Eight seconds between the next frame, thats pretty
darn good.

Well the image lasts way past 8 seconds not sure how long the longest in time CRT Screen Persistence lasts for ,i only know of P7 type and it can out do it .
40 or 50 years ago it would of been all the go for any slow scan tver ,invented to late but never to late for any one interested .
