Built me a multi-standard mechanical televisor

[Aussie Bloke]

G'day all.

I recently brought up the topic of mechanical television as I've in recent times have taken a big interest in it. Well after building a few simple working televisors, one being cardboard, one of plywood and a tin can drum televisor, I have decided to make a multi-standard Nipkow disc televisor consisting of 3 spirals of holes (60 line, 32 line and 30 line) and two orientations of scanning, horizontal and vertical. Anyhow been working on it on and off for about a month and have got it up to operational status and it is making pictures on all standards!

There is much to say on the construction of this set, so those who are interested in knowing details on the construction of this set I have posted a thread complete with pictures on the construction of this set in the NBTV forums:

I have uploaded a 25 part video series of the construction on my set to my YouTube http://www.youtube.com/user/troysvisualarts/videos and have made an uncut telerecording of the set in operation using a super sensitive 1990s Panasonic camcorder http://www.youtube.com/watch?v=qwYiAJMnc8c , the pictures as seen are far from perfect as I didn't drill the holes accurately but nevertheless it's making pictures.

Anyways this set is still a work in progress as I will be refining it over time, will have to drill another disc with better accuracy and get some brighter LEDs and make an effective speed control system for the AC motor as I am finger braking the motor's spindle pulley to sync the speed.

Here are some pics of my set
