I think if you flip the tear collector the other way it will be fine.


I'm going to print this one out!

I think there might be meta-stability issue with the logic in this thing..

I've seen this before and no longer clearly remember it's origin, but IIRC it may have originated with one of the big U.S. semi-conductor companies a few decades ago. For some reason National Semiconductor or Analog Devices comes to mind. (It'll turn out to be one of the others.. LOL)

In the 1960's Popular Electronics (or maybe Radio Electronics) magazine ran a column every month called Noteworthy Circuits that had clever or unique circuits posted with a short explanation. The April issue had a slightly different theme called Notworthy circuits. They were usually a whole page that resembled this one.

Signetics used to publish paper "data sheets" for non existent devices. The sales rep would drop them off when he brought data books. There was the "Dark Emitting Diode", the "Smoke Emitting Diode", the Friode" and the "Write Only Memory". Those paper data sheets have long ago crumbled into non existence as did Signetics. I do think National made a few too, but all of this fun was long before the compter revolution. Google will turn up references to people who remember the old data sheets, but no actual copies.

Googling around returned a link to this forum where I posted a similar answer about this very same circuit.......I know where we have seen it before!!!

I gotta build me one uh these!

Hi there: Should one side of the open circuit be connected to the loop antenna which encircles the diagram? ...regards, Michael

It's an Holistic circuit, so it's probably all connected anyway
