Interesting.  Some of them do have that concave edge.  Thanks.

Bill

Same arrows on that one. Super cap or battery, the device is nothing special. Bring on the next fake self-runner for analysis.  ;D

Yep, that looks like the exact unit. I  learn something every day! It could be 2 CR2032 batteries shrink-wrapped in series with welded-on tabs.

Anyhow, I just tried the circuit, with these substitutions:

For that mystery object I used a 1F 5.5 V capacitor.
For the motor and reed switch I used a small reed relay, Gordos 831C-2. This is a 5V relay but it works down to about 2V.
For the Schottky diode I used 1n5819.
For the BaTiO cap I used a tantalum 0.47 uF.
Instead of a White LED I used a green one, I'm out of whites.

The circuit "works" ! In that it does oscillate the reed relay, lights the LEDs and keeps running when the "loop on" switch position is selected. But.... there is one major fail in my build. My reed relay has a snubber diode built in,internally, across the coil!
 :-[
This probably kills any spike-recharge effect that the thing might be able to produce otherwise.
I can hear the reed relay "singing" well, in both switch positions, until the voltage drops to just above 2V or so. (ETA: Sings in switch "loop off" position only when external power is supplied. LEDs light regardless, since they are powered off the cap/battery thing.)

(The 1F cap is on the back side of the board)

And could be on its last legs at 72 years of age.  ;)

Hi Hoppy,

But it is much younger, only 35 years old because the first number you see as 1 in the 1942 is in fact 7, so it is 7942.  And this means that the first two numbers, 79, represent the last two numbers of the manufacture year i.e. 1979 and the 42 means the week number in that year.

So this reed relay may have many years to live unless Tinsel abuses it which is not likely...    8)

By the way, Larskro uploaded another video, stating there is no battery: https://www.youtube.com/watch?v=UI_EfWRepIQ

Yes, that was a great year to be a youngster!  :)

Heck, I was 21 in 1979.  I was still in college then....sigh...I miss those days.

Hi Hoppy,

Thanks for the links.  I was 27 in '79. 

Bill, yes those good old days I wish they could come back...   :)

Yep, I was 29 and married a year. Those days never to be repeated.  :(

Larskro published his 3rd video.

https://www.youtube.com/watch?v=UI_EfWRepIQ

(Edited, I just corrected the link to the right video)

The circuit diagrams from Groundloop and TK are right, now you can see all the red cable connections to
the switch.

He now removed the 2 LEDs. ( I don´t know, if the 2 LED  polarity was right in the circuit digramms,
but these are probably not so important in the circuit as he removed them now..)

But unfortunately no more infos.. He just only turned the circuit around..
So it still could be a RF induced effect or a hidden battery inside the motor...
Who knows...
He has to come clean, as in the past he had a faked device...

Regards, Stefan.

Hi TK,
well done,
can you remove the freewheel diode from the Reed Relay ?

Hi Stefan,

The link you gave is for his first video.

This is the link for his 3rd video:  https://www.youtube.com/watch?v=UI_EfWRepIQ    as I posted in Reply #35 above.

Argh. It is always something. No measurement of the climbing voltage : I have no doubt that the cute litte motor will run for a while on the capacitor only, especially without the drain of the LEDs! But does the voltage rise, which was the most important thing?

The thick baseboard is also very maddening. Any good craftsman can hide a lot of stuff in there without it showing. This is probably a deliberate Red Herring, though, just a tease on his part.

No, it's a completely sealed up plastic 14-pin DIP package , I probably can't mess with it without destroying it totally.

I may have another one in the box that I can try to disassemble. They are -- or were, in the last century -- available without the diode, though. I just can't find any other reed switches at all in my stash right now.

The relay is SPDT and I tried hooking an inductor to the other contact to try to get a collapse spike from that one but I couldn't figure out how to get it to go back into the circuit without killing it, since it's timed 180 degrees out-of-phase.

I have considered trying to make the little motor from scratch, and using a Hall sensor or even a mechanical commutator for the switch.
