Maker Faire 2008: The Transistor Clock

[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.

[plentylego]

so it wouldnt work in europe

[bedeone]

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

[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?

[3yE]

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

[ZerqTM]

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

[CesarTkgo69]

oooooh si

eso si que es la escencia

de la electronica jajajaja

Saludos, felicidades

[Pujc]

Oh goodnes mee wow , awesome , thats amazing , unbelivable much work , great!!

[juice667]

I'm stunned.

[bilzoo2000]

i wonder if it could be made of relays...

[VideyoJunkei]

maybe...but switching speed and wear would not let it run long...

[peterwilson69]

Wow! Awesome!

[mello67]

wow, a lot of work, cool

[adisharr]

Cool project :)

[Membrane556]

Thats really cool I can see why it won though nixie tubes would have really matched the discrete circuitry though it would be more complex.

[GratefulJWB]

No, actually a Nixie version would be slightly easier by eliminating a couple hundred diodes used in the 10 to 7-segment conversion. The 1 of 10 outputs are already present. What would be needed is to use high voltage transistors in the 1 of 10 stages (with a 170v power supply) or use high voltage transistors throughout and power the entire clock from the same 170v power supply. There has been discussion of making a Nixie version in the Neonixie yahoo group.

[madamerotten]

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

[Membrane556]

It would be huge bigger then a refrigerator though one could make a clock of manageable size if they used dekatron tubes.

[callbigg]

Cool!

Whats a Transistor clock?

[Rarcoan]

A clock which mostly consists on transistors. In this video, he's using loads of transistors and resistor. Nowadays, we only program the digital clocks. It's quite impressive to make a clock like this.
