Quote from TK:


He's up there at the head of the stairs with his arms crossed like Andy Capp's old bird:

"I want you to do some work of your own for a change".


Here's a few more to help:


"Put a tie on!"

"Take the trash out!"

"Get a Job!"



You are a troll, you know. An ignorant and arrogant one, to boot. Why don't you go away and make your "contributions" somewhere else.

Take a look at Igor's schematic in his "REED SWITCH" II video:
https://www.youtube.com/watch?v=vWvI7T7h3tk
Igor just jumps his magnetc switch with an LED anode to positive, and gets a self runner!

Look, He states that he watched the motor run for six hours untill he got bored with no drop in input voltage. What more do you want?

synchro1:
TK is correct about you misrepresenting Igor Moroz's work.  Igor Moroz does not refer to his reed-switch spinner as a self runner, that is your misrepresentation.

At 1:15 in the Reed-switch Spinner ll video that you posted a link to, Igor Moroz states: "The last one was running 6 hours and I just stopped it because it was a constant fall, very slow, 1/1000's of volt but they go down."  He is clear about his findings and does not mentioned being bored, that is also your misrepresentation.  You state misrepresentations as if they were facts.

"Self accelerate"? What motor doesn't self-accelerate? Are you missing something here?
Skip ahead to the 4 minute mark if you like.

Larskro just posted a new video showing the heat charging up
his tantalum cap.

Okay, this heating effect is simular to the effect I have seen in 2011, when I heated
the 10 pieces 100nF caps in parallel with a hairdryer and got the voltage raised
from about 9 Volts to about 100 Volts when applying temperature.

I wonder, why he in the start has also 4 Volts at the tantalum cap, as the diode
is still in series in the circuit, so normally the voltage at the SMD cap should be about 0.3 to 0.7 Volts higher than the
voltage at the Tatalum cap...

Anyway, the capacitance decrease of the SMD cap when heated, drives up the voltage at it and
stores it via the diode into the Tantalum cap.
These effects are real...


But I now also think, that his motor setup is faked.
As TK is right, when the switch is in the Loop OFF mode and no battery is connected,
the motor should not spin on so fast.... it should stop pretty soon or decrease in RPM pretty rapidly...
but in Larskro´s case it seems, that the motor is still powered then by a hidden source...
I don´t believe, that the motor has so much flywheel weight, that the RPM is so
slowly decreasing...

So again another fake from Larskro.... tooo bad...

This isn't the same guy that showed a power strip plugged into itself and powering stuff is it ?

Maybe this one by Larskro's fake too? who knows:

The effect of disconnecting the power and self looping speeds the rotor up! This acts like some kind of "Lenz Delay" effect!

Could there be some fiddling with the slide switch?
Is it possible to have a slide switch that works like a toggle switch, where the contacts _opposite_ the toggle or lever are the ones that are active?

Anyhow, I have the MiniPulse working down to 0.1 volt with the reed switch inside the relay, so I think it can be used as a legitimate substitute for the little generator/motor from the water nozzle thingy.  And I've configured it to use the Larskro circuit, with the exception that I'm using the 10F supercap instead of the 0.47F cap, and I have a tantalum cap instead of the magic monolith. The behaviour is very interesting, and leads me to ask the above question.

I'll be making a video to demonstrate this a bit later on. Anyhow, I can show the cap voltage climbing with the rotor turning and the input power disconnected, and so on, but not in the switch order Laskro presents. When the input power is unplugged and the switch is actually in "Loop OFF"  my motor does not run, it only coasts.

Hi TK
how fast does your motor reduce in RPM ,when you switch to LOOP OFF mode ?

Does your Tantalum cap also rise its voltage when you heat it with a hairdryer ? If not just use 10 pieces 100 nF ceramic blocking caps in parallel.

Regards, Stefan.

Slowly enough so that one might be fooled into thinking it is actually running rather than coasting.

I don't know but I'll try it and find out. Certainly, small batteries do rise in voltage when heated up and this voltage rise actually represents usable energy, as I've shown with the DALM Joule Thief.

I have a bunch of small BaTiO monolithic capacitors in glass envelopes, they look a little like diodes. But they are mostly very low values. I may be able to do the heating experiment with them anyway. I seriously doubt that this would produce usable power, though.

One could try comparing the power output (not just voltage) of a standard thermocouple junction, and the magic capacitor, heated at the same time by the same source. I would imagine that the TC junction would be more powerful.... which is probably why we don't just use capacitors instead of TC junctions for temperature measurements.

Can Larskro run his tiny motor using a TC junction and a flame for the power source?

I've cleaned up the MiniPulse motor and prepared it for a demonstration video in full "Larskro" mode. I'll be making the video today, after I mow the grass.

I can show the cap voltage on my 10F supercap building up, but only in "loop off" position, and the motor is of course coasting at that time, as is Larskro's.  This is just a dielectric recovery effect though; it happens even if I hold the rotor motionless with my fingers.

Regardless of whether or not the Magic Cap is providing power to the circuit (why isn't it being sucked up by the bigger cap?) the schematic posted by Larskro has no means for running the motor when battery is disconnected and "loop OFF" switch position is selected, because the Reed Switch is disconnected in that mode.

My tiny waterfaucet generator should be here in a day or so, but the MiniPulse motor parts are working really well. It runs, or at least turns under power, down to below 0.1 volt input using the reed switch from the little reed relay. Given 1.0 V, it really goes, and with 2.7 volts it is screaming, over 11000 RPM. I put another layer of thick heatshrink tubing over the magnet armature to help prevent it from flying apart.

After adding the tiny 33pF 500V  capacitor across the reed contacts I have had no more difficulties with the reed. I've run the thing for many minutes now, at high RPMs and low, and the reed is working well. I do have a few spares, but it will be interesting to see how long this one lasts.

Here's a little progress report.

I received my order of 4 of the faucet LED generator things. But I wasn't able to get the generator out intact. This model is so well potted and the wires are so very fine that I broke coil wires and there is no hope of repairing these tiny wires. But I did manage to get the generator housing/bobbins/magnet/shaft assembly out without damage other than to the coil wiring. So I stripped off all that little wire and now I have the bare generator capsule, waiting to be rewound.

Its shaft has no bearings, of course, and it comes to a stop pretty fast when spun by fingers.

The faucet things look pretty neat on the faucet, changing from blue to green to red depending on the water temperature. This might actually be useful, since one of the disabled housemates has lost the ability to feel temperature in his hands. Might prevent him from scalding himself someday. The thing is noisy though, the generator spiral-flow thing makes an audible whine.

Mine is pretty quiet; the circuit board was like sealed to the end with acryilc in mine... like the whole bottom end of the coil/board is in acyrlic (there's a few bubbles I could see)


Part of the reviews on the home depot site was 'only lasted like 8 months'  ... without bearings it's gonna wear out the plastic and get noisy; but it's cheaper with fewer parts :)

  Some pages back there was  a pic of the Cap with legs
on both sides and it was thought that it was a battery.
Well, FWIW, I have the remnants of a shake light and it
has the same looking cap in it.  It is a .22 F cap and not
a battery in my instance. Not building this but fun to read.

Thaelin:

Nice to see you again.  Yes, that is a supercap.  I got my first one by taking apart one of those shake-lights and I used that cap and lit an led using my very first (crude) earth battery.  That little cap acts just like a battery, which is why I have run many things from ones like that, as well as larger capacitance variations up to 650 farad.
