So, that motor is from one of these?
http://www.ebay.co.uk/itm/LED-Faucet-Tap-Water-Glow-Temperature-Sensor-RGB-3-Colours-NO-BATTERY-NEEDED-UK-/321164725289?pt=UK_Home_Garden_Bathroom_Taps_PP&hash=item4ac6e8cc29

Yes it looks pretty like that, except the threaded end is on the outside for the ebay offer and Larskro shows such head with the thread obviously inside because of the thicker collar ending where he helds it.  https://www.youtube.com/watch?v=jmG-MaijNv0

But this mechanical fixing difference cannot matter for the built-in generator, so it is very likely that the same type of generator is embedded in the ebay offer.

Here's another type of mini generator. This thing/torch has button cells in it which get recharged, I thought that odd. But even if the switch is off the LED's light up when pumping the mechanism to spin the magnet. One pump and the magnet spins quite a while. I guess it depends on how charged the batteries are.

Anyway the coil can be changed fairly easy on this thing I think. This one has a disconnected LED wire so I thought I would show it here while I had it apart.

Cheers

I'm not sure but I think that the thing probably never actually sees AC from the motor coils, except in the sense of the inductive ringing. I think it's operating as a quasi-synchronous pulse motor. So the coil is pulsed once, briefly, during one half of the rotation and coasts the rest of the time. There will be some generator effect during the coasting probably but I can't quite wrap my head around it without actually having a working apparatus in front of me.

I tried another micro relay, had it all wired in, only to discover that it, too, has a diode across the coil. So I'm going to have to build my own little motor I guess. And dig up a plain reed switch from somewhere. Although I have been playing around with a Hall effect sensor; maybe I can get that to substitute for a reed switch.

Okay, thanks.

Using a Hall effect sensor sounds a good idea, its open collector output itself might be able to survive the peak voltages.
I will ponder on a kind of controlled rectifier too.

Hi Farmhand,

PRobably the generator you show is able to work as motor when you give pulsed DC or normal AC to its 'output' coils?
I mean there seems to be no brushes and Larskro's generator also seems brushless so this is why I ponder,  chances are the type you show can work also as a motor.

Hall effect transistors can't deliver the "Reed Switch" magic that results in the self running effect. The Hall effect transistor resists  the kind of backflow current the Reed Switch allows. There's no way to improve over this kind of circuit's simplicity; Reed switch in series with the power source and self looped! Proper timing allows it to hit and restore the capacitor through the reversed biased LED's with correctly polarized BEMF.

Larskro's latest video. A "Self accelerating (Reed Switch) magnet motor".


https://www.youtube.com/watch?v=g1tvbb_LDTM


Milehigh and Tinselkoala developed their Op-Amp circuit to replicate this kind of self looped Reed Switch simplicity with Integrated circuitry. Are they threatening to drag  us over yet another unworn section of twisted and tortous path leading who knows where? Here's the bacon Larskro brought home in the mean time:


Larskro heavily bias's his Reed Switch with a lever magnet. I mounted my Reed Switch directly to the coil face! This is not a fake!

Hello,
I will attempt to replicate this as the cost is low, and it is a small project I can take with me on my travels.

I snagged an image of his hand drawn schematic from Larskro's  latest youtube upload.

I have ordered faucet motor/gen lights from this vendor as they look to have the square type motor/generator as used by Larskro, and fairly inexpensive. 4 pcs for $12.00 free shipping in US.

Hi,

Larskro has just modified the info on his capacitor in parallel with the supercap:

"Sorry sorry - I wrote a multilayer nanocrystal 0.47uF in the video part 1 and in the diagram, this is wrong.
I remembered wrong, it is 10uF 25volt. I have controlled this now."
 

So it is 10 uF and not 0.47 uF... 

You can read it under his schematic video: https://www.youtube.com/watch?v=4eUIf6UEdbA

Okay, in the 7th video he said now,
that he used this generator:

http://www.ebay.com/itm//261210903782

and now also corrected the SMD to 10 uF / 25 Volts.

25 Volts type I did not find on Ebay.com

only 10 Volt types

Be cautious with the Temperature rating.

X7R are the very linear caps.

This:
http://www.ebay.com/itm/300915920797
has alreay the better nonlinear Y5V temperature ratings..

You can also try to get Z5U.

I will try to ask Larskro which one he uses..

Regards Stefan.

Some have asked how this motor can at all turn,
when the Reed Switch is only pulsing the coils.

Well I really think, this generator is only one coil
with a very strong magnet inside.
You can see, that it is very strong, as Larskro approaches the
other shower head the motor already begins to rotate a bit into position
of the field the other shower head forces upon him...
So just pulsing it shortly from the caps or batteries makes the
magnet rotor probably spin pretty fast already and then the reed switch is also
controlled by the magnetfield of the rotor, so the reed switch opens and closes
at exactly the points, where it propells the magnet rotor.
The other 2 magnets on the wood plank are only there for
premagnetisation of the Reed switch so it better opens and closes
with less flux change in the air...

So it is really an interesting device.

I hope he does not have any button cell battery hidden below the motor
somehow..
Also he should still show, how high the voltage will climb...

Regards, Stefan.

Has anyone noticed the similarities to the Bedini window motor as well as the Keppe motor?

That's right, there really isn't a mystery about how the pulse motor runs, it's a fairly ordinary construction, it just has the coils or rather a split coil surrounding the rotor instead of separate from it.
The mystery of this device is the climbing voltage as it runs, and the report of the rotor accelerating, until he deliberately stops it.

I'm working on a little pulse motor with a Hall effect sensor switching a mosfet to drive the coils. It makes a nice sharp backspike, with somewhere between 8 and 12 times the input voltage. (Input 4.2 volts, spikes collected into a capacitor reach over 58 volts.)
 
Unfortunately since it's using a mosfet (IRF3205) it needs at least 4 volts to run (mosfet gate threshold voltage) and is not really switching fully until 8 volts input (mosfet fully turning on). This voltage requirement means it won't be useful for replicating Larskro's device.

But I've ordered a set of those LED water nozzle things from Ebay, so I hope to have the right generator/motor in hand in a few days, if all goes well.

Meanwhile here's the circuit for my MiniPulse and a photo of the motor itself.
