G10/241E, DZ10 and 11TU7 up and running!

[Dekatron42]

Hi,

While trying to create order from chaos in my hobby room I decided to test a few of my Nomotrons, the Cerberus DZ10, the STC G10/241E and the Tesla 11TU7 before I was packing them down moving them to my storage room.

I made three short movies and put them on YouTube here: https://www.youtube.com/channel/UCO6OM4QT3HjXeLpF3FSlsMA

I either used circuits from the datasheets or from "Electronic Counting Circuits" by John Brian Dance. The important thing was to keep the pulse width correct, more so than using the exact voltages, so that the Nomotrons would count correctly. Unfortunately my camera broke down destroying a memory card and the battery some time ago and it seems that the photo sensor has become sensitive to some wavelengths as filming the DZ10 resulted in some purple lines.

Regards,

Martin

Too bad that dekatrons like the 11TU7 aren't more plentiful. Does anyone know the history and usage of these "readout-like" tubes versus conventional dekatrons ?

That 11TU7 is nice. Wish the other nomotrons were that pretty.

I have a G10/241E. When I 1st received it, I ran it in a simple circuit. Not an attractive tube at all. When I was done testing it, I put it away in storage. Haven't turned it on in a couple of years.

This exceedingly clever animation by artist Alan Warburton transforms two compositions from J.S. Bach’s The Well Tempered Clavier (Prelude and Fugue in C Major) into a visual interpretation of music.

Theme of the video ... Don't let an art or music major, hook up the lighting in your parking garage ! :)

Ya know, before the video moves to the garage, it plays the same few notes, over and over, for some time. You can rig a dekatron, or nomotron, to sequence those notes. Gonna have to try it sometime !
