Howdy folks. I have some bad news. It has just become painfully apparent that the summer is a mere two weeks from its conclusion. Where did it all go? Can't we have a little bit longer? Please? Hrmph, I guess not. That means we need to make the best of the next dozen-or-so days by […]
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:
- 74AC240 Octal buffer chip
- 4 x CP0.1µF capacitors
- 100k resistor
- 2 x 47k resistors

Resistance is Futile if < 1ohm
Hey, look at us! We made a witty, over-used joke! But seriously, this week we have a schwack-load of resistors for you. Normally we save most of these for our internal use, but what's so fun about that? So we've gone ahead and opened up our entire inventory of 5% accuracy, 1/4 watt resistors. There […]
