The exact question would be:
Is the data transfer , during the ATR stage, between chipcard and cellular, the same as normal serial data transfer like from some serial cable to PC ?
Am trying to define how the ATR characters are passed when chipcard is...
Hi.
I am reading something regarding this standard and there is a part about smartcard and reset. If the ATR signal consists of some characters then is it normal to look at ATR signal as onto standard serial connection package transfer ?
Am trying to define the characters inside the ATR so i...
stepper motor schematic
Hi !
Can someone give me the link where i can find schematics for connecting stepper motor on PIC 12F675 ( or some other microchip MCU ) ?
Thank you.

Hi !
This is not so much of question as advice...
In my project am using permanent square neodymium magnets (10x10x3mm) and i want to make magnetic shielding on them.
What kind of materials are u using ( mumetal, something else), and what's your experiences with such shielding.
I found some...
I must agree with both answers because am thinking on the same way.
Cuz i can not test it am still confused. It's normal what chemelec has written but am not quite sure that this could be it, because this voltage should increase the magnetic field, regardless of small power ?
Hi to all !
I have air core electromagnet working on 4,5V DC.
What would happen if i pass let say 500V ~ 10 mA thou this electromagnet ( from tesla coil ). Will this make stronger magnetic field ?
Sorry guys for such long respond, i had some stuff that i have to end...
OK.
This is the idea that i want to use:
Windturbine rotor -> transaction wheel gear -> 55 Amps alternator -> AC output
As you can see there is no battery after alternator.
This is partly because this is just test and...
Thank you !
I get the picture how this should be done.
What about reducing motor speed ? How will this effect on motor.
Or is there some low voltage (1,5v ~ 200mA) DC motor with less then 100 turns per minute ?

Thank you for reply.
In original i was thinking on this:

but up-down direction would be even better.
I apologize but i dont fully understand your drawing.
Am making this at home from old...
circular to linear motion
Hello.
This is what i have:
One 1,5 dc motor spinning at max 300 turns per minute.
What i want to do :
I want to attach some let's say egg shaped metal to the motor stator to get linear motion ( look at photo ) BUT linear motion should go in both directions ( left...
Hello !
I don't have alternator but before i buy it i need to calculate the power output.
Am going to use the car alternator and rotor that should be connected to alternator is spinning with 70 turns per minute.
How to calculate the alternator output power ?
