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 .
