"Our OU toy"??  Now that's funny...  ^-^

TinMan - and Grum -- any photos of these pushing-the-envelope toys?

Then we can shop around, see if we can get our ou toys on e-bay...   :D
That would be a hoot!




Wife will be heading off to work shortly,and the video camera is alreading charging. ;D ;D ;D ;D

Oh man.....
a family heirloom taken to the slaughter.... :o

and you do remember rule number one in the OU builders hand book

 rule number 1]  NEVER TAKE APART A WORKING OU TOY !!

@Gyula, thanks again...learning lots here.
I had always thought that MOSFET diodes were around 1.2-1.5V and often higher. I'd certainly never considered them for anything but MOSFET work. Very interesting indeed. Will certainly peruse those datasheets. I did look at one just now and saw it's small signal transistor type of packaging. Makes me wonder about some unknowns seen on scrap circuitboards (the source for most projects parts).

@TinMan, I find it hilarious how some fellas half a world away know what you're doing, but your own wife doesn't, AND that you are posting about it, with the camera charging up right when she's there ! LOL



Have built the 2nd motor.
8 coils, 4000 ohms seemingly on the dot. Coils have read between 465ohms and 544ohms, as taken from the circuits.
It's all completely rough, but that was the idea, to see the improvements based on the rough.
The rotor is, get this, from one of my wife's old tobacco chew tins ! She was never much of a fan of cigarettes, so opted for the chew. Stored a bunch of them in a drawer in case I needed them for anything, such as Altoid tin projects.
Hotglue has been used, it allows fine movements by remelting with the soldering iron (yep that old trick). Though, Fix-All and superglue don't seem to want to stick at the moment, warmer days needed.

It did an hour on a 0.1F cap charged to 0.9V, not bad for a first run. It's really slow though, because of the ceramic magnet weight. But, at least we know that ceramics will do an hour, if you see what I mean :)

Wow
talk about serendipitous moments...
I was just thinking about a Frantic Brad trying to get things Back where they belong
Ball bearings and springs flying out [the usual nightmares]
and then a plea to the populous for a quick replacement _until_ he gets this one back together  ...
so I clicked onto this thread to see where he's at and there you were
with the same thought....

funny stuff this OU Toy Biz...

But knowing Brad and the seriousness of this operation,I'm sure he suited up in the white suit with the pressure mask and is working in his 1.5 atmosphere, clean .dustless and hermetically sealed safety room.

this is a very touchy and sensitive area...taking apart the wifes historical [17 year] family heirloom for OU research
wars have been started over lesser offences.

Well yeah, how do you think the Irish got jailed and then carted off to Oz  ;D
Those wives wanted their fellas at more than arms length !

Only joking, of course.



Here is the 'Spider Rotor'.
The other is too heavy, i've decided, great low speed performance but that's not the idea.
So, its spindly legged self is on test at the moment.
Will probably have to grab some N52 5mmx3mm, similar to those on the first build. This was fun however, chopping up a hard drive magnet with pliers.

Do let me know if anyone following has bandwidth issues, if on cellphones and the like for videos and i'll post pics of progress.

Well just joining all the videos together,and i managed to put it back together with no left over screw's-->which would have been preaty silly as it only has two screws in it O0

Anyway-Slider,you will never guess as to what circuit this thing has in it lol.

Will upload video,and then post here as soon as it's done.

It is funny when you look at it like that,but my loving wife doesn't pay much attention to this crazy stuff i do-although she gave me a mouth full of disapproval when i electrocuted my self a couple of months back. :o

After proof watching the video,i just realised that i never did the capacitor run time test lol,trying to get everything done quickly so as i could get it all back together before !she who must be obeyed! returned home.
Ah-my wife isn't that bad,I'm sure she would understand O0. I remember some years back taking apart her electric cake mixer so as i could see how the speed controller worked. It all went back together,and worked just fine-except for that scraping noise when it was running. She of course took this opportunity to go purchase a new cake mixer,but on the up side of that,i got the old one O0

You trapped the family cat in it ?

Looking forward to the vid !

As a guess, I'd say a high ohm coil, run cap, pair of transistors Collector to Base, throttled heavily with a large value resistor.
Or, something completely related to this thread project, like a high ohm coil and a reed switch.

Dear Steve.

Photos attached. It seems ASDA, now part of Wall Mart, the term " Long Life " certainly lives' up to it's name !!  :)   Both cells read slightly > 1.5  VDC, 13 years on. This toy was bought for our first Grandson who is rapidly approaching his 16 th birthday !!

Cheers Graham.

Mark, I feel we are hijacking your thread, my apologies.

Courageous of you to take the toy apart while your wife was out, Tinny -- made me laugh.
VEry simple device indeed...

Great video Tinman  O0
Was completely surprised to see that the transistor was a regular vanilla C945.
A replication will be made, using 2 x 'dancing' coils on top of each other (likely a new thread).

Oh no problems at all here Grum, all is related to efficiency.
I'm delighted about the learning from all the great posts. Fun too :)

Steve, I think this is the circuit operation (will draw it out at some point, have just worked it out in the mind):
ETA, am editing this as I take another look at TinMan's video, because it seems that 2 wires connect to the Emitter !
Negative from battery goes through a coil winding to the Emitter of the transistor.
Positive of the battery goes to the Collector.
A connection goes from the Emitter as the 2nd coil, around to the Base.
That's the full circuit.
When the dolphin rocks, the energy that would be picked up by the Base of the transistor is induced into the first described winding, sending it back to the battery. The EB diode of the transistor works somewhat like the reed switch of the EZ Spin, completing the return circuit.
So - when a pulse is fired through the transistor, it sends the dolphin rocking and when the dolphin comes back from the pulse and the transistor is off, the energy goes into the battery. On the next swing back down, the voltage is induced in the correct direction for the Base and the transistor fires again.

Dear All.

So he, who shall remain nameless, or at least expletive deletive, got copied by the Chinese, who created an almost self running house decoration !!  :) Irony ??

Brad, how do you think the decoration might run connected to a couple of 5 F 5V super caps connected in series ?

Cheers Grum.

Great! you're a mile ahead of me, Mark!

   We'll see what the circuit looks like as you get it (wish Tinman could have rotated that circuit a little more..) 
Note:  From what Mark describes, it differs significantly from the Ber-dini SSG (IMO).

Mark - keep in mind while doing the replication, if you can think how any energy floating around can be re-captured, that's a good goal.  IOW, the coil fly-back, is that being recaptured?  perhaps the return swing of the pendulum also...

   I like the simple pendulum action... there is already a type of resonance there, as the period P is well defined and depends on the length L of the pendulum (from pivot point = low friction!) to the center of mass of the mass M (in this case, magnet).

  Note that the period of the motion T is simply:
P = 2*pi*sqrt{L/g}
plugging in 9.81m/sec^2 for g, we find to a good approximation:

P = 2*sqrt(L) in SI units.  So if L=1m, then the period is
P = 2 seconds!   

The period is the time for round-trip, out and back, returning to the same spot.
The shorter the "string", the shorter the Period - but it does not depend on the mass of the pendulum at all!  just depends on the length L of the pendulum.

Im not sure Steve, but I think its due to capacitive or inductive coupling between the two coils being in the bifilar situation.

I did run it on the 2200uf cap with a starting voltage of 9.4 volts-same as the battery. But it only ran for about 4 minutes. I thought it would have done much better than this.
Im going to have to put my hand in the fire here , and ask my wife if I can carry out some test on it, as there is something I want to try with it. 2.5F @ 9 volts would give a good run time I would think Grum

I foresee an excellent use for the heavier ceramic magnets !
To explain, usually nowadays, the 'dancing' toys feature 5mm x 3mm neodymiums. Previously they had larger, heavier ceramics of rough equivalence magnetically. The store manager said on Saturday "last year we had 10 boxes of these devils and they all went in a day"...and there it is. Looking underneath, we see 2013 stamped and so they'll be to the ceramic spec.
For the dolphin, the flyback goes through the circuit backwards, enabled by the diode inside the transistor (do correct me if wrong anyone). The very movement of forward and back creates that effect by default, with no extra components required. It's very similar to the EZ Spin and what we know of its ability to return energy.

A mod to the dolphin, would be pickup coils up and down the travel distance, at least either side in the middle, where speed is greatest !

Aha, good info and thanks for doing that. The first EZ Spin that I made did 1 1/2 minutes on a 1000uF charged to 1V. it's somewhat similar and i'm really wanting to try the 'dancing' coils idea for the extra resistance.

Yeah, Brad, do you recall the actual circuit connections ?
I'll wing it, as I think I know how it's wired, but would like your input :)


---------------------------------------
Here we have the MicroEZ.
It's as small as an 8 coiler can be, using these coils.
It was tried as a build, to see if there needed to be a clear 1 coil space between coils, to allow for the phantom pole.
As it happens, nope, runs ok lol
Not very quick again and i'm really wondering now whether that first 4 coil build is the way forward.
Many coils = sipping of voltage/current but slow speed. 1 or 2 coils = high speed, fast power usage....are 4 coils and 2 magnets the Goldilocks zone ?

Edit: Fixed some spacings between coils.
There were panel gaps that British Leyland would have been proud of  C.C

It's just the cool joule circuit Mark, with both coils wound on the same former. What you didnt see was the small ferite rod that fited into the small hole in the coil former
So start of one coil to base, and end to emitter.start of the second coil to battery +, and end of second coil to collector. Negative of battery to emitter.

Thanks Brad...thought so, but also the Positive red wire seemed to have a thin wire connection within the solder and that confused. It is probably a loose strand from that battery connection
I have my best version of your Cool Joule still running. It's right there on the table.
Took some video a few days ago with various projects as an update, but didn't post it, the CJ was in that....kinda think I should have posted it, to link with the Dolphin.
Speaking of wives, the table you see in these vids was 'new' to us last year and Julie wanted it kept clean and nice, with a vase and flowers. Errrrrm *cough*

Question - after watching a video by Erfinder and considering the lack of speed etc of this latest MicroEZ build.
Can I short every other coil and gain anything ?
Edit - and the update. It's pretty funny, I linked every other one, therefore simply bypassing every other one. Spun it up by hand, with 0.855V on the cap and it slowed immediately to a crawl...and kept on going ! About 1 RPM.
The 4 will now be tried as paralleled gen coils instead.

I can't comment on the shorted coil question, however, the arrangement of E's coils is important to taking advantage of Lenz' law. I can't see a reason why it can't be incorporated into this setup.

Thanks Bob.
Maybe there are clues in the latest set of experiments this morning, because it's odd to me and at least needs clarification from others.

All tests have been with approx 0.9V on the 0.1F capacitor, which has been connected throughout.
The MicroEZ had 4 magnets, 8 coils and ran slowly.
Shorting every other coil to basically remove every other resistance, resulted in 1 RPM running.
Well, there were now 4 magnets and 4 coils, fair enough.
2 magnets were taken off - same thing, 1 RPM, yet it was exactly the same configuration as the 29hr original build !
I decided that it must be some kind of friction issue, because without the reed it still slowed itself rapidly to a stop.
Adding graphite to the needle still resulted in a rapid slow and stop with no reed switch.
I disconnected 1 coil, so the path was now open circuit and the rotor spun around very freely again, to a very gradual free running stop.

In effect then, perhaps, these air cored coils are showing immense Lenz force, by simply being bypassed - the total opposite of what 'E' is showing ?
Another question, and perhaps a silly one. If I connected the 4x shorted coils backwards, would anything change ?

The set up of the MicroEZ, is now as follows.
4 compass point coils untouched, regular connections.
SE coil disconnected completely.
NE coil reverse connected.
NW coil shorted to either side coil
SW coil shorted to either side coil.

The rotor pulls to one side, but runs at twice the speed as it did when all 4 minor compass point coils were shorted.
Still very slow with rotation, but somehow has improved in this arrangement.
Is this related to the way that a magnet will drop slowly down a copper tube ?

Here's a brief video to hopefully explain.

[youtube]XK3d5rPf8ns[/youtube]



Update: With all 4 of the minor compass point coils completely disconnected, the motor runs freely and at similar speeds to the original build.
