@all

I am testing all what is possible with  UCC (within my possibilities of course) 

the test bench is very simple as usual        i simply let pendel  and swing different arrangement of magnets through different   UCC  and scope the results

at the first glance  Lenz is a very CORIACE  boxer and does not  intend to be beaten so easily   even against himself  :P

@ Yucca

i will probably need your soft to go forward so if your offer is always in value i am very interested

good luck at all

Hi Laurent,

Your oscilloscope looks very nice with maths functions, what make/model is it?

Yes, I have finished the software for now, so if you do order boards then I can PM you the software anytime you like. Then you just load the program and solder wires onto the controller.

The software now has these features:
User can specify even number of rotor magnets in one line of the code before programming.
adjustable delay period specified in tenths of degrees. (also displayed in microseconds).
adjustable pulse width specified in tenths of degrees. (also displayed in microseconds).
accurate RPM readout.
Strobe light LEDs.
Optional audio feedback click once per revolution.

I plan on adding one more delay and one more pulse output for further experiments.

My motor has been running for over 24hrs at 200RPM consuming about 40mW, when I throttle it up it throws magnets at 1500RPM because they are only stuck on with doublesided tape. I want to build a wheel that will go faster.

@yucca

here a picture with denomination of the scope

i have ordered today the 2 moduls for programing the timing

as soon as they arrive i will contact you for your soft

@all

completely out of topic !!  and just for fun   i used my UCC pendulum test  to try  to replicate the Veljko Milkovic small pendulum chariot    it took me half an hour to build this crappy replication  but it works fine and it is really fascinating to see the gravity walking horizontaly :o     perhaps it will be a new thread for this purpose

good night

Laurent

@all

in  process  in the workshop and waiting for my timer    why not powering the pendulum of a Milkovic  2 stage oscillator with a UCC

in the picture the pendulum is a stack of magnets      and now let's make the circuit to time it right

the wheel in the middle works with a ratchet system     at the present it is  much too crude to be effective   but let's experiment  we will anyway get something interesting ;D

good luck

Laurent

Hello Laurent,

this chariot-pendulum : how did you power it ?
Via the coils ?

Do you have a link to the original website where there is a description of this device ?

Really good stuff Laurent

woopy I have a few predictions to your motor and I would feel real honored if you tried them out?

First I predict your motor will work as good if you used two (or even three) separate oppositely wound coils instead of a single U coil.
My second prediction concerns shielding one pole of the magnets. I predict this will give you substantially better results. You'll need to shield the pole that enters these coils first. Shielding  should not be perfect. This prediction can be tried without the first to see if it's true.
And my third prediction. Instead of shielding them you could use two magnets stuck together and repelling each other on the rotor.

All these predictions may be wrong but I would REALLY appreciate it if you experimented with them.

@Kator

no  i do not use coil for propelling the chariot  i only used the Hard drive axis that i i use to test the UCC by pendeling magnets through the UCC

i mean that the chariot works only with gravity    i simply let the 2 pendulum "fall down" by gravity  and the chariot  go forward  as Milkovic does with its chariot  on his desk in the video of its original site. You can get it very easily  with Google  simply type MILKOVIC and you get a lot of info on this man and his very interesting work.

@ Broli

thank's   but can you be more precise     i have seen that you are  a very good designer     so some pictures would be  helping 

"@Nieves

thank's for sharing

very nice work

are you solving the high voltage versus power output ??

cheers

What I am trying to solve is the voltage disappearing mistery. The voltage is on the batteries until you use them with a load, that the voltage just disappear.
The circuit seems to charge the battery, but the charged battery cannot be used.

Oke I have used your existing drawing. This should need no further explanation. You might need to experiment with putting the shield on either sides. Because you might get a negative effect of attraction past TDC instead of the push you would want.

Edit: I forgot to draw in the two magnets repelling suggestion. But surely this doesn't need an illustration. Just stick two magnets, that are repelling, together and replace it with your current magnets and discard the shield suggestion.

@Broli

thanks  i understand better what you mean

@Yucca

hehe i have received the Freeduino today :)

i am downloading the necesseraly soft and drivers

can you post or pm  your brown cicuit and how you made the alimentation and connection of freeduino?

and of course if it is always actual i would be very happy to get your programation ( i remember that i am far from beeing a champion in electronic and i learn every day thanks to this forum which is very interesting)

cheers

Hi Laurent,

You wont be disapointed ;)  You might want to think about getting a spare arduino chip for the board just incase you blow it, I haven´t blown one yet, but I keep a couple spare just in case because they are really cheap considering the chip is quite a powerful little computer:

http://cgi.ebay.com/Arduino-Diecimila-ready-Atmel-processor-ATMEGA168-20PU_W0QQitemZ380097884976QQcmdZViewItemQQptZBI_Electronic_Components?hash=item380097884976

For the driver circuit you will need:

OPTION1:
=================================
1)
Any common N channel FET (I use IRF730)

2)
FET Driver IC with 5V supply capability (I use UCC27322) the driver IC makes sure the FET switches hard on, without the driver IC the microcontroller signal (5v) will only partially switch the FET on and it will have a high SourceDrain resistance, this will waste lots of power as heat.

OPTION2:
=================================
You can use a "logic level FET" without needing a driver IC which is simpler.

I will PM you the software tomorrow as I´m using a laptop in bed now and the rest of the house is REALLY cold.

For now if you can install all the soft and drivers on your PC and can figure out how to load up the nokia screen demo program then it will make things easy for you when you come to programming up using my code.

Instructions for the demo prog are here:
http://www.nuelectronics.com/estore/index.php?main_page=product_info&cPath=1&products_id=10&zenid=208b4e44750d05a4ea4ff0c1b1844bff

The nokia screen shield has solder pins along the top with numbers, you can solder all your input and output wires directly to this. Or if you can get very thin wires you can poke them in the sockets on the micro board and then plug the screen on top of them, trapping the wires as you plug the screen in.

Best, Yucca.

@Broli,

Your idea of trying to swing just one pole through the coil... Maybe we could achieve that by using long rod magnets and just have the N or S rod end swinging through the coil. The opposite end could stay away from the coil and be close to the wheel centre?

Of course it would be good to try your way with shielding as well.

With the single pole passing through the coil we could apply two pulses per pass. One attraction pulse just past TDC and one repulsion pulse as the pole leaves the coils edge.

Yucca.

thanks for sharing

i recieved your soft and your explanations :)

my freeduino does operate  right and now i have to get used with it       very new stuff to me but very interesting   very good challenge

so far i see it is not possible to send picture on PM   so i send you a picture of a problem which occures by opening the DEK UCC soft in arduino  ?  (nothing is connected to the board)

i will order some  "logic level fet " next week   i actually have some IRFP450     do you think i can try to make some test with this Fet   in direct contact to the gate  or it could be dangerous for the arduino ?

good night

Laurent
