LMR Live show as a Podcast?

Hey Chris and Rik,

I know your posting the live show on ustream, but what about taking the next step and making a podcast available for download on iTunes?     or is this already done and I dont know it?

because of the number of eye balls on iTunes, it would be amazing exposure for LetsMakeRobots.   eventually you could even have sponsors that would pay real money, or at least throw you a servo once in a while.

I listen and watch a lot of podcasts, and judging by what I've seen from some of them, the LMR Live show is perfect material.

Stepper Motor Guidance

Hello, thanks in advance for any guidance you can offer on how to use these stepper motors I have.

they are 4 wires, red, black, yellow, gray.

3.1v, 3.6 ohms, 7.5 degrees


I know how to operate servos with PWM, but steppers seem to be more complicated, some have 4, 6, 10 wires etc.  unipolar, bipolar, etc.

based on what I've said so far, what can you tell me about what I have here, and how to control them, hopefully with PMW like servo's?

thanks again,




Hopefully provide you with at least 1 useful bit of guidance.
