@ 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

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:

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:

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.

@ 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
