Donald Smith Devices too good to be true

[symbol]

I almost never post on forums. This time I could'nt resist.

@mr clean: Great work! Please refrain from altering anything on the working circuit.
Maybe the reason why you cannot replicate it lies in the components used:

- bad wire? In your video "39C Don Smith Device Project Bitoroid HV Resonant Drive Transformer Tune and Testing" at 10:07 you mention that.
39C Don Smith Device Project: Bitoroid HV Resonant Drive Transformer Tune and Testing - YouTube

- cold solder joint on your speaker wire with the crocodile clips?

- probably you've once oversaturated your core material?

- bad transistor?

=> luckily you don't have so many components that's why I hope you'll find the missing link soon!
Keep up the amazing work!


@verpies:
1) The turn counts of windings W1, W3: probably mr. clean put 200 turns on each secondary, see his post:
W2: Video 39C at 0:55 - 29.5 mH on the primary

C6 & C7: Video 39C at 10:17 - 17 nF "on either secondary"

"as i arbitrarily just put 200 turns on each secondary"

All the best! -s

[Dave45]

all coils are wound the same direction, except the primary was wrapped from top down, finish layer, and start again from top down etc..

L1 29.5mH and 100nF
L2's 178mH and 17nF on each

but there are not many turns on L1 maybe 60 or so 20 gauge wire. thinking of adjusting the numbers and observing the results, but not sure to go more or less

Looking back over Kurt's post's.

early gedanken

From the videos, it appears that (in 39F) the +12VDC battery is disconnected but the +9VDC is still connected to the PWM oscillator circuit.

The PWM is not isolated from the 3055 ckt, and they share a common ground.

If the above is correct, then it is not "self oscillating" - the oscillator is still running and possibly affecting the ckt.

[everything below here is moot, if I've misunderstood and the PWM ckt is actually turned off...]

The base of Q1 is driven from 0V to +1.4V, and the base of Q2 is driven from 0V to +0.7V (at whatever freq. the PWM is set at).

With the 12VDC battery disconnected, the collectors of Q1 and Q2 are floating (and, they are probably connected together - can't easily tell). The collectors are probably floating up to the base voltages (or some "random" voltages (higher than the base(s)) from within the coils).

Question: is there an ammeter connected between the output of the PWM ckt and the base of Q1? How much power is the PWM ckt pumping?

The light looks like a triple-LED to me (i.e. not much current needed, only voltages in the diode-drop region needed).

pt

ps. The ckt posted thus far is incomplete - there's big cap, a diode or two and a 1-ohm(?) resistor involved - which, of course, makes analysis inconclusive.

[mr.clean]

You just managed to get OU and INCREASED output instead of decreased output when one of secondary coils IS SHORTED.
The alternate flux path you provided takes Lenz force away from primary coil and additionaly shorted secondary becomes POSITIVE generator for another secondary so it helps instead of blocking.
If you watch your own previous videos carefully, in one you said, IN = 12V 0.5A, OUT= 30V 0.5A and in that video when you short one secondary the lightbulb in another secondary lights up even more. This is where I replied here to your post with feeling you got OU already...

that is exactly what i feel as well, at resonance it got to a peak brightness, then adding other coil was significantly increased, so if anything it is a good direction

Ok everyone, keep in mind it is very touchy, and is very rough, and i just dont want to mislead anyone, but this is the wiring from the last video...

this being the video...

39F Don Smith Device Project: BITOROID IN SELF-LOOP, WITH LOAD, NO BATTERY NO CAP - YouTube

it looks like on the scope it was about 757hz and minimal duty cycle, but i had it tuned for 2.94khz, anyway

please everyone, if it doesnt work, dont spend too long on it, i dont want to be responsible for anyones frustration but mine, ive had to put it down for a bit, going insane trying to do it again

that being said, enjoy

Then please open that schematic diagram in MS-Paint (or any other graphics editor) and draw the additions/corrections with a mouse, including the test equipment connection points.

I will clean it up even if you do crappy mouse-drawn disagram.

i agree, this is very odd, and yes it must not be self oscillating due to the 9v in PWM, but it is not the source of the power, without a battery pulse, the PWM cant run the circuit alone, only run the base of 2n3055, but that wouldnt explain the sustained increase in meter reading, anyway, i know that doesnt help much lol

OK,rough is fine by me, just let me know what's inside those 2 "AMP" blocks?
Are those "AMP" blocks identical?

Also, you have 4 terminals on the PWM pulse generator - please annotate them (e.g. positive power supply input, pulse output, ground, etc...)

How is the +9V created for the PWM pulse generator's power supply?

those are ammeters, both reading unmeasurably low, BUT if you actually connect the free wire of cap, the output ammeter dips off the scale Negative, then slowly goes to zero and the cap discharges as usual, but unconnected is where i got the strange results
here is the way the PWM circuit ties to the 2n3055

[mr.clean]

totally agree . Thank you mr.clean for hammering it out and Love you for your excellent find. The one thing that looks like a really good device for the poor . in all countries if you get your double blind replication . Please don't let the cat jump on it if you got one . I have been there .

The sig gen question is my first thought but i have one you can get for free called the Ts-3001 . it only takes 1ua @ 1 volt . surely you can get that off there somewhere .. get them here a great PWM varaible and Free with free ship . read here Touchstone Semiconductor Introduces the New TS3001, a 1ľA, Accurate, Easy to Use Timer IC Simple to Program with Just One Resistor
and here are the demo order page High Performance, Low Power Analog ICs from Touchstone

thats very cool man, thanks for this

[janost]

I finaly got the courage to connect the transformer in a CT configuration with the shorter winding in series with the bulb.

I made the open winding resonant with a 330nF cap.

The bulb lights up fully and the current draw is 15w.

With 233v in, the voltage over the bulb is 232v.
But what is interesting is that it is 10.5v over the transformer and it should be 1v only.

And the resonant side has 105v as it is a 1:10 transformer.

Thanks Mr.Clean for sharing and Congrats for your results.

Thanks Kurt,

My team just did first measurements with alternate flux path on rings and found few interesting facts:
1) The inductance of Leeedskalni's primary coil increase when load is applied to one of secondary coils (this is opposite: In the standard transformer the inductance decreases when load is applied)
2) The reactive resistance is increased under load (again it is opposite from conventional transformer)

The more measurements with recorded video will follow as my tean's work will progress.
