KABTronics TubeClock


I'll be testing myself against it in a fight to the death:

  • 215 Transistors
  • 518 Diodes
  • 472 Resistors
  • 101 Capacitors
  • 10" x 14" Printed Circuit Board with silk screen symbols indicating component locations

Who will win? (My money is on the clock).

Bloody hell Ian - you're going to coat your lungs with solder fumes!

My idea of a perfect weekend!

That'll keep you busy. My son suggested I build a clock like this:

What you really need is one of these:

None of that newfangled transistor nonsense...

Hmmm. That begs the question of whether you could use nixie tubes to create a nixie tube clock, if all you need is a difference between striking and maintaining voltage. IN-3s spring to mind, but a 10 state switch would be more ambitious....

Perhaps a suitable topic to get someone started on neonixie?

Ha ha...I have one of these too Ian and I haven't rallied the courage to tackle it yet....going to be a monster build. I may just wait for your take on it before I fire up the of British!
