from 0:14 to 0:17 it sounds like the begining of inspector gadget dubstep watch?v=oib0JvkDzYk

@HeadShot360IN i was about to tell him to make a dubstep from the motors XD

Hi. Could you post the controller's schematics at your site? Thanks in advance

@despedes Hi. I have a newer version at my site:

"Double PWM controlled H-bridge for interfacing with an Arduino"

It's almost the same. There you can find schematics and board layout.

Extreme loud... does not sound like "smooth" steps.

Could you do this with mechanical relays? Or would the relays not be able to follow such fast changes?

@mate2000 a mechanical relay can't switch as fast as an electronic switch

I think your web site needs updating cause from the circuit you have there, I dont understand how your clipping the signal. I love the video and nice work. I havent tried running my motors in bipolar mode but I do have a current limiting circuit built. I measure the voltage across a .5ohm resistor by first inputing the voltage into an active low pass filter and then a comparator which is feed into the enable logic gate. Nice work and please keep me updated.
