Joule Ringer!

[Lynxsteam]

I don't know who reads these posts but perhaps you can pass this along to the offended parties.  It was not my intention to "rob" anyone of anything, circuit designs, their rightful place in our esteem, their turf.  I just bumped into this stuff (joule thiefs, joule ringers...) trying to find better ways to use wind power.  Using an aircore transformer, induction coils, alternator coils, is something I have been using for quite a while now.  I thought it was very clever to try LaserSaber's simple circuit with the aircore.  Evidently, that was a "no-no".  The aircore is not great or better than what LaserSaber shows, just different.  But apparently not different enough to start a new thread.  I apologize and I am sure the thread will fade off.

Anyway, sorry for the encroachment, I will bow out of this area of exploration.

It is difficult to comprehend how anyone could feel "offended" by the
development of the discussion and all that has been included.

There is really nothing new under the sun.  Each circuit and its several
different variations that have been presented are all "re-hashes" of what
has been done by others long ago.  As one who's been working with
semiconductors since 1960 I can assure all concerned that the Joule
Thief/Joule Ringer circuits (even those with the 'load' in the base drive
sub-portion of the circuit) have been conceived/tested/evaluated by
many, many experimenters in the past.

The ONLY aspect of the circuits which is new and revolutionary is the
Light Emitting Diode.

It is difficult now to find documentation relative to the early work done
with these circuits since the hobbyist magazines have largely disapperared.
I happen to still have a copy of an old document MIL-HDBK-215 dated
15 June 1960 which is titled "MILITARY STANDARDIZATION HANDBOOK,
SELECTED SEMICONDUCTOR CIRCUITS."

Within its over 300 pages of circuits nearly every conceivable transistor
configuration is dealt with - including several versions of the blocking
oscillator which has come to be known as the Joule Thief.

The earliest home made Capacitor Discharge Ignition Systems which
many of us constructed in the '60s relied upon flyback generated high
voltage (400 - 500 Volts) which was produced in several versions of
single transistor blocking oscillator.

For anyone to think that they've found something new and incredible
which hasn't been seen before in transistor power oscillators is just a
bit disingenuous.

I cannot see where Lynxsteam should feel any need to make apology.

I can see, on the other hand, where some may wish to look into the past.

  Although I don't know what is going on with that, just wanted to let you know that your input is really, really apreciated. This project is one of the most important things happening.
   So, please don't let the flies spoil the cake. Just shoo them off, and forget about them,   please, just do it for us.
   Thank you,
                     Nick

Huh?    I've been on these forums for approaching two years now and any time someone puts an idea or circuit up PUBLICLY, it is "open sourced" that is, you are free to take it and run with it however you wish.  And your contributions BACK into the community are much appreciated!  You don't have to, but YOU do, and that is great!

  No one owns any "turf" on the air-core or JR or SJR circuit, that I know of.   
I wouldn't worry about that.   

Please do NOT " bow out of this area of exploration."  I'm certainly not going to.  And I intend to keep sharing also.
I agree with comments of Nick and Seamonkey above.

PS -- this is too fun to let egos get in the way of the fun... although, sure, we are human.  Faraday and Sir Humphrey Davy come to mind -- but Faraday continued despite the opposition nonsense from Davy.

  This is an OPEN_SOURCE forum; we are working together, most of us, to see what we can learn and do.  Most have altruistic motives for humanity, I believe, but also just having fun with electronics and discovery.

Great work JouleSeeker!  64Lm/watt.  How much do you want?

I'd like to beat the "world record" for a commercially-available LED bulb -- currently around 135 Lm/W (based on a quick literature search some weeks ago.)  A few mods to my set-up and I'm up to 71 Lm/W this evening.

I am glad the discussion and exploration continues.  The "Magic" is partly that we are exploring, trying different things and having fun doing something useful. 

I totally  agree.

A couple notes: 
I can't get anywhere near beating the E-Core with the Aircore (to be expected). 

Can you tell me -- how many windings on the primary and the secondary did you use?  Primary first on the spool? easier to tap if on the outside...

Did you use the LS 2.0 circuit without adding any diodes or connection (through a resistor) of the base to the positive rail?

T

here are some resonant points on the aircore that give really good results
Without the HV hooked up to a load I got quite a shock off the 12v positive lead while hooking up the aircore.  I am pretty sure the battery is part of the LC tank circuit and its charging between cycles.  Put a diode on the negative side of the battery and the circuit doesn't work.  If this is the case the battery may also be part of the limiting factor and part of the tuning.  I get better results with a large lead acid 12 v rather than a small nicad pack.  If the oscillations occur without the LED bulb then perhaps the bulb is not the big factor in the circuit but more along for the ride.

Very interesting!  How do we capture the energy kicking back to the battery?

I am where Joule Seeker is with playing with ferrite, but with an enclosed magnetic field around the aircore.  This then is no longer an aircore.   I am playing with completely enclosing the coils to see what difference it makes.

My goal is to get total power up so that the ten bulbs are closer to fully bright and that we maintain the self adjusting ability of the circuit.  I want to avoid core losses and eddy currents in the core material as much as possible.

PB291 says the core is not saturating, Conrad says yes it is.  Could it be the Battery resistance is the limiting factor and confounding everyone's results?  Batteries have resistance and it is very difficult to measure.  It is usually between 1-4 Ohms.

Right!  this is "no longer an air core".    (So Pls don't worry about somebody's turf....  I must say, the remark about an air core idea being "robbed" - strong word - over at EF has me perplexed and annoyed a bit.  Hopefully there will be an explanation.  Meanwhile, guess I'll stay away from the "air core 2.0" for a while myself... was planning to anyway...  )
