Otto`s replication of Steven Mark`s TPU

Hi Earl,
See post:
message 33776

As I understand it, and Otto may need to correct me, I think if you follow the lines on the drawing of the coil arrangement for the 6" and 4", there are two independent loops of wire coupled by an air space, so in effect it is like some kind of tuned capacitor. With each of the two plates made up a 6" + 4" loop of one conductor of the lamp wire.
The way the loops appear to be arranged mean that +ve plates for each half of the capacitor (6" and 4" loop) back onto each other.
The only bit I am not sure about is if the twin core cable is laid flat or is vertical.

What sort of frequency generator circuit are you proposing?

Hi Rob,

I will be proposing simplest and cheapest, able to buy parts at most electronic stores or mail order, nothing exotic, standard, everyday parts.  In spite of this, still the highest quality oscillator, very stable with low-noise and low spurious.  Analog Devices solution has parts difficult to obtain, expensive, and DDS has dirty spectrum.

There are several possibilities, depends on Otto's frequencies.

In my Moebius strip drawings, yellow and turquoise only exist to show twist direction.  In reality, they are air or maybe some insulation.

In meine Moebius-Zeichnung, gelb und turquoise Farben sind nur da um umgekehrte Drehrichtung zu zeigen.  In Wirklichkeit sind sie aus Luft oder vielleicht Isolierung.

Hi Earl,

Analog Devices solution has parts difficult to obtain

In the UK and USA they can be sourced from Farnell and Newark respectively.

expensive

Cost in UK ?4.50 + vat
Cost in US $8.00
Samples from Analogue Devices Qty x 2 free.

and DDS has dirty spectrum.

At very low levels compared to the main signal and can be removed with a couple of extra filter components.

But it is quite complex for the average person, but this is the way I'm going and I may be on my own on this one.
Ahh well I tried...

Hi all,

I DID IT

THANK OTTO!!!!!

Please as I'm writing full-time no discussion now...be patience for a few days.

Roberto

I assume you mean you got overunity--CONGRATULATIONS!!
