Donald Smith Devices too good to be true

[zilano]

thank you zilano
i will try to build one .
what type of capacitor you use in your device ?variable?
do you use capacitor variable or coil variable or frequncy variable to get resonance ?

thanks in advance

i use lcr meter and calculate cap. earlier i used home-made caps. then i used variable also with hard disk drive platters and made air capacitors using shaving blades also they worked for my crystal radios. u can use tin foil also. the aim is to have many metal layers insulated with each other and connected in parallel.

variables are better as they keep u in control of resonance.

ps: for high voltage use thicker insulater so not to make spark jump across.

hi zilano
original device of don smith he use spark in serial .if he use resonance should be used parallel capacitor to get max power output. and he use step up transformer
please what final and easy circuit you use.

thanks

Don used pulsed dc to xcite parallel coil cap combination. where as people adapt Tesla type primary oscillator.





Don method is easiest. when pulsed dc is fed to parallel coil cap combination the LC circuit oscillates at its frequency determined by L and c combination.
when u r making Don device just Follow the way He did it. there are many ways to harvest power but Don circuit provide the easiest and the best way to learn and make the device. when u learn the basic from this device u will understand resonance and what it can do. u only have to slide in and out the primary to tune secondary. To use power the easy way to use voltage divider circuit and pushpull transistors to drive the transformer. if u have ferrite transformer its much better. one can use iron cored also after the inverting transistors.

there is similarity between ac adaptor and Don device. but transformer is reversed and made air-cored primary is at lower voltage than secondary. if u understand adaptor circuit u will understand don circuit. its an adaptor circuit with windings of trafo reversed and resonance used.

if u follow Ac adaptor circuit and understand it then Don circuit is not beyond ur understanding. just keep in consideration of high voltages and resonance.

PEOPLE DONT HAVE SUCCESS WITH DON DEVICE AS THEY DONT FOLLOW dON SMITH. THEY FOLLOW TESLA AND APPLY TO DON SMITH. WHEN U R USING TESLA TYPE INPUT THERE MUST NOT BE ANY DIODES USED IN PRIMARY CIRCUIT. WHERE AS IF U FOLLOW dON SMITH THEN DIODES MUST BE USED AS SHOWN BY HIM.

PS: when frequency is not matched or not in resonance then output can be zero. if matched its max!

ok thanks
concerning the 35khz when i use flyback driver with Capacitor across 8T coil it doesn't change the frequency what i need according to Frequency formula

Hi all

thank you nutgone`s and all best

... continuing

Stage 3: achieving HV and HF

When we have a stable dc source, in the next stage we should step up the voltage to approximately 4000V and the frequency above 20KHz

For driver circuit I use feedback, but I think it would be better to use ZVS /zero voltage switch/

Follow Don way to xcite primary. its Dc to be pulsed by spark gap.
u can even use a fwbr and follow Don bertonee circuit. Dc has no frequency and when u feed it to Lc in sudden spurts the coil cap combination oscillates. according to L and c.

now it is very clear
the frequency just to get HV pulsed DC from Flyback and the key is the resonance on Pr coil with Se coil to get max power
thank you zilano

Hi all

some update of my work

thank's to Dragon , MrClean and Kajunkreation very good help

And of course all contributors

good luck at all

Nice job woopy ! keep in mind you can further isolate the "collector" by connecting the AV to an antenna or large mass instead of the ground.

thank you zilano

Exactly. Overunity is in two factors :
- Q factor
- Lenz-less transformation

We all know that power can be amplified by capacitor , yet Yesla knew he can do the same not just for impulse, because his one impulse produced then continuous oscillation many minutes long.... He described one of his oscillators still working 3 years after ...

Shocking!

OK, so my build goes on.

Today I did my HV module coil, as per Patrick Kelly's eBook, but I'm getting some funny results.

I'm powering my HV coil (8 turns pri + 4000 turns sec) via a 12v, 555 based, variable oscillator & a IRF9130 FET (as per Patrick Kelly's schematic, chapter 3 page 63).

So, why did I get a nasty shock from my variable resistors when I went to adjust the frequency???

My FET is also getting VERY hot, so I've gone for a bigger heat sink.

I can't do much more until my new LCR meter turns up & I can start getting some HV caps for resonance tuning. Here's what I have so far.....

Hi Woopy!

great going woopy!

fire it to trafo now to light the bulb!

good replication!

great effort on ur part! admirable!

goodluck in all ur tests and builds.

keep the cold end of ur hv coil earthed to prevent shocks!
