Stepper driver using only 555

Hello!
Is there anyway to make a Stepper Motor Driver using only 555 IC's???

Thanks

 

It may be possible for a low-power stepper motor, but it would be ugly and awkward.

It's sort of like "If your only tool is a hammer, everything starts to look more or less like a nail..."

The best use of a 555 with stepper motors would be to provide a clock, at either a variable or fixed rate, for the driver circuit.

 

Thanks. I understand that it's not efficient, but we are allowed to use only 555 IC on this project. That's why I was asking for that.
Do you have any idea of the circuit. I've already tried to move my stepper with 4 555, with no success.
If anybody has an idea to make it work, I'll thank you so much. (Sorry for my bad English)

 

Here's the information:

I'm using 9 volts.

I've 2 motors:

Here are the datasheets:

M42SP-7:

M35SP-9:

And the schematic:

 

I touch the 2nd terminal of the 555 with my finger xD.

 

That's a better idea!! Thanks I'll try using monostables instead of astables.

 

I've the circuit done. It's not perfect, but works fine (at least while simulating).




Thanks for your help. Your idea of using monostables was the solution.

Notice that the 2nd 555 has a node that connects its 3rd and 6th terminal. With this connection, the circuit doesn't stuck up.

 

hi ivan
some of the best drawing ive seen, what are you using?
if ivans gone, anyone anyone recognise it?
