Lidmotor's Penny circuit help needed.

And I see you got your registration issue settled. Great!

I hope you don't mind if I still call it the DALM thing, though.

Still oscillating... collector peaks 1560-1580 mV at 490 kHz, 18 percent HI, battery voltage still 0.340 V.
Interestingly, the scope reports the "average" collector voltage as 340-350 mV.

IMPORTANT NOTICE:
I mistakenly had "0.340 mV" when I should have had 0.340 V, or 340 mV. I went back and corrected the earlier posts.... sorry if I had anyone all excited. Please calm down, if you thought I was running something on under a millivolt. Not yet! It's holding steady at 0.340 V, or 340 mV, which in itself is rather amazing. I'm starting to think it might be picking up some power from somewhere else.

Well, it is still oscillating, the voltage on the battery is now 334 mV, and the collector peaks are at 1260 mV, and the average collector voltage is about 340 mV.

So I am curious: this is the first time I've looked at the DSO's reported "average" voltages of the JT's spiky signal when the LEDs are not on but the thing is oscillating anyway. And I've noticed that the average collector voltage is nearly exactly the same as the supply battery voltage. Does this hold true for other JTs, I wonder? Do any of the JT researchers out there have any data on this question?

Meanwhile...

@ Shemp:  what happens in the sim if you "rotate" the transistor and hook it up incorrectly? That is, hook up the Collector of the transistor to the point in the circuit where the Emitter normally goes, and hook up the Emitter of the transistor to where the Base normally goes, and hook the Base of the transistor to where the Collector normally goes?

Want me to remove the 1.2nF cap?

I am finding this amazing because it is still going and the voltage hasn't seemed to slip any.  Might not be powering any LEDs but for something to be running this long and the voltage hasn't budged smells funny but in a good way.

btw, it seems my notifications are on but I am not getting any which is odd so that is why I did not reply as quickly as normal.

With or without the 1.2nf cap it doesn't oscillate.
