PhysicsProf Steven E. Jones circuit shows 8x overunity ?

[nul-points]

hi Steven - long time! - apologies for absence - as our mutual friend Nerzh Dishual can report, i spend a lot of time off-planet these days  :-)

most of the little 'free energy' time which i have these days is spent on my 'water' battery interests, but i do still dabble with pulse circuits from time to time (solid-state and motor)

checking in at OU.com again very recently, i was interested to see your report of LaserSaber's Looper circuits

so i thought i'd see if i could incorporate some of the things which i've been learning from my previous experiments...

at first sight the LaserSaber Looper test on 'Mothers' Day looks like quite a radical development, but in fact it is still very much a Joule Thief

it appears that the Transistor base circuit is incomplete (ie.  having just one terminal), but in fact it has all the usual connectivity - its just hidden in other components

- the secondary of the transformer (ie. base winding) is only connected directly to the base at one end, but the other end is coupled by 'stray capacitance' to the primary winding just as surely as if we had used a small value capacitor

- the 'missing' base bias resistor is provided by a 'leaky' junction impedance in the transistor itself

(i believe that LS mentions he had to use a Germanium device to get the circuit to work - i used a low-leakage NPN device (BC547) and had to supply a path for the base bias current, in my case i used a reverse diode, which in a sense was like externalising a base-collector PN junction)

LS chose to drive his LEDs across the base winding which was efficient in terms of the circuit layout, but the effect of LED current is entirely dissipated in the LEDs - i've chosen to drive the LED from the collapsing coil field current, which enables me to direct the current back into the supply battery

i confirmed that the circuit operated ok inside my (unenergised!) microwave oven

i tested the capacitor run times for a few circuit variations - using a 2200uF electrolytic (low ESR), charged from a 9V battery, all the circuits lit the LED for just under 30 minutes (very very dim at the end of run) - this time reduced to approx 28 minutes if i left my datalogger probe connected to observe the discharge profile

the LED was lit while the cap voltage discharged from 9V  down to approx 0.43V

i also checked the capacitor discharge caused by the probe and self-discharge - the voltage decreased from 9V to approx 7V in 30 minutes

since LS only used 2 of the 3 windings in the 'Akula-type' transformer, the primary is only driving its energy into the LED load on the secondary

moving on to battery operation,  i've used 3 windings in a multi-toroid transformer i made a couple of years back (trying for a Jensen type transformer action), which frees up the secondary to drive only the transistor base, and now i can use a 3rd winding to 'pump' electrons back across the supply battery connections in recharge mode

...details to follow...

...hmmm - not sure that images used to appear so large when i last posted a couple years back!  apologies!!


for my first battery-supplied run i monitored the battery just with the probe for about 5-10 minutes and then connected the circuit

after that point the circuit started to exhibit the ability to vary between periods of discharging, maintaining and increasing the on-load battery voltage (see graph for 1st 36 hours of runtime) - battery 'at-rest' voltage, before connection to circuit was 7.583V, this morning, a day-and-a-half later,  the voltage is at 7.586V


are these 1000mAh NiMH AAA cells really being 'trickled-charged' by this pulse circuit?

my capacitor discharge curves indicate that the circuit is drawing approx 27uA - ie. it is equivalent to a load of approx 285K ohms
 
i connected the same LED type across a 9V battery with a suitable resistor to produce approx 27uA and the LED appears to be lit at a similar level

the graph (shown below) of the battery terminal voltage for 36 hours of circuit operation certainly gives no indication of a discharge trend - BUT - each cell is currently in the 'flat' region of it's discharge profile - if say, the cells are approx 50% charged, the circuit is only drawing 27uA from a battery with approx 500mAh of charge capacity remaining

[EDIT - the voltage axis on the graph is generated via a x10 probe - so read the voltages as 7.XXX volts and not 0.7XXX volts! )

it would take approx 500 / 0.027 ~= 18520 hours = 771 days = 2.1 years for this  load level to discharge this battery (ignoring cell self-discharge!) - so any discharge trend probably wouldn't show until the logging had run for several months

i've now swapped out the pulse circuit from the supply and re-connected the battery across an LED in series with a 220K ohm resistor to produce a comparable passive load - i've also left the 2200uF capacitor and large inductor across the battery for this test, as they are contributing buffer storage across the battery in the case of the circuit also - my next test will be to remove the capacitor/inductor and just log the battery loaded by the LED and resistor

we will now be able to see if our pulse circuits are adding any special behaviour to a rechargeable battery-powered setup, compared with a straight passive load

...watch this space!!

all the best

Hello Nul-Points,

So you are back! With very very interesting stuffs as a bonus.
Great...

Since a big couple of months, I keep on saying that "hidden" capacitors are a big clue.
I keep on experimenting with strange (air) capacitors embedded in coils (CapCoils).
The idea is from Vladimir Utkin, not me.

Very simple: one plate of the capacitor is the coil windings itself,
the other part is a (non-shorted) metallic foil.

Apparently, almost nobody seems interested in my results.
No 'OU' claimed here, but an apparent NoDrawBack effect.

- the secondary of the transformer (ie. base winding) is only connected directly to
the base at one end, but the other end is coupled by 'stray capacitance' to the primary
winding just as surely as if we had used a small value capacitor

IMO, you got the (not null) point here....

All the best,
Jean

heeeey - Mr Dishual!

great to meet you here

your reps of these 'Indacitors' look very interesting

have you ever read about the transmitting aerial which is like a  hybrid coil-capacitor?

i think a student heard about them and implemented one on the roof of a radio station in his homeland, in the Middle East somewhere - i believe they worked amazingly well

have you been able to get any test results yet?  what sort of circuit is suggested?

i seem to remember reading about a coil split midway down by a disc capacitor - was that Utkin?

there's so much info - so little time left for me to look into it


my spring pendulum powered by water batteries has been bouncing away since Feb - the cells should have polarised by now, but it's still flashing its LED & pulsing the magnet - i must be doing*something* right! 

i'll try and keep in better contact

all the best to Brest

Hello,nul-points!!!

It has been a long time, NP!  great to hear from you again.
My turn for apologies as I've been helping my son in town with some home-problems (plus fighting a cold...).  So I just came to OU and saw you posts minutes ago!

Welcome back, my clever friend!

I will need some help starting Saturday morning on a build that I will be testing, so if you're around, I seek your help.  (Hope Nerzh and others will jump in, too.)
I'll show photos that day.
If you (and all readers) get the opportunity, please review the circuit and short video by LS here:
http://laserhacker.com/?p=410

The design will be the latest by LS, below on the right, compared with your 17 May ckt above.  I like what you've done for tickling the transistor base.
