...Well, sorta. We won't have a full booth like we have in past faires, but that's because Austin is sooo far away, and it's not easy to bring all our gear down that far. So we'll be down there assisting in the Maker Store. Feel free to stop by and say hi! We'll be near […]
Circuit: Stepper Motor
Dave Hrynkiw
July 12, 2007
This is a neat little one-chip circuit we originally tuned for use with our "SM1" Stepper motors. We've presently sold out of the motor, but this circuit has proved to be a good unidirectional (1-way) driver for small stepper motors. Parts required are:

- 4 x CP0.1µF capacitors
- 100k resistor
- 2 x 47k resistors

"IT'S NOT DEAD! JUST PINING FOR THE FJORDS!" Well, that's not the case. But is does (did?) have beautiful plumage. But that's okay […]
