Developments with my homemade vidicon camera project
 

G'day all.

In the past month I have finished off the construction of my homemade vidicon camera project and am now testing it and fixing bugs. So far no picture yet, however I am getting dashed lines moving across the screen in all directions. All the details of the vidicon camera can be seen on this page of my website http://www.troysvintagevideo.741.com/mycamera.html . I even made a video of what I'm so far getting on the TV screen http://www.youtube.com/watch?v=6zW6y...layer_embedded .

Anyways Richard Diehl from www.labguysworld.com is kindly helping me out his wealth of technical knowledge on camera construction and electronics giving me technical advice to help get this camera working and also am getting techo advice from a couple of other contacts as well. So hopefully soon I will get this camera going and will make video demos of it in action. I have to of course get a better CRO with calibration to properly test the waveforms as my equipment is not quite up to par to do the job accurately.

Wow! That's really cool :yes:
I recently picked up a Hitachi 8837 and RCA 7735A vidicon tube. It would be fun to experiment with them, but I don't have deflection coils for them. Where did you get yours ?

Thanks. I borrowed my deflection yoke from a non-working Sony AVC-3250CE camera I have.

A surplus store in my town has a bunch of vidicon tubes. If you need any specific ones, i can go over there and look through them.

Some really good news. I have made major progress with my camera today and now sort of have a picture now, a squashed picture that is. The picture vertically fills 1/5 of the screen at the top. I can guess there's something in the vertical section that still needs to be fixed. Anyways I've made a video of the camera in action http://www.youtube.com/watch?v=WkZNMAAFf80 in this video I move my fingers in front of the lens and as seen on the screen. I wonder if anyone here can tell me what is causing this vertical issue?

I also now have a Tektronix TAS475 CRO which I got from a vintage TV collector for free so I now can easily get accurate readings from the waveforms and can make necessary adjustments when needed.
