Maker Faire 2008: The Transistor Clock

IEEE Spectrum held a Maker Faire contest for digital clock makers. Keith Bayern won with his clock made only of transistors and other discrete components, with no integrated circuits. To find out more about Keith's clock go to www.transistor-clock.com.

Now, I'd like to see a digital clock with the same 7-segment readouts, using only vacuum-tube triodes.

[ZerqTM]

Meh! he should have built it with vacume tubes instead :3

[super4chicken]

now build it in minecraft

[faffaflunkie]

Oh, how I wished you used Nixies for the display. Because of that you only get an A-.

[Wwallace67]

This is easy. You should do it with vacuum tubes. Oh, it looks like I'm not the first to make this observation.

If one set out to invent a bistable multivibrator anew from scratch, one better take time doing it. :)

@plentylego Nope, in Europe it'll run slower since US uses 60hz and EU uses 50hz ;>

[plentylego]

so it wouldnt work in europe

[caticeasu]

this is some cool shit

[Esperantanaso]

This thing is extremely cool. :)

[anjwicks]

Could he have figured out how to do it with software first?
