Re: Yet another magnetic loop antenna

I've used both the EasyDriver and this one from Polulu:




I found the Polulu to be a more robust driver.

Excellent write up. I've recently finished building an air variable cap and the next project is integrating the stepper and building a controller.?

Could you use relays to control your driver micro stepping with the Arduino? Also, you might want to look at the Sparkfun EasyDriver. It has logic pins broken out that can set the stepping from full to 1/8 and also an enable/disable pin. I also have a Chinese EasyDriver clone which was a fraction of the price of the original but I haven't tested either yet.?
