Ok, yes, we know. This is yet another late cool link post, but... We have a good excuse, honest! We just got in a second laser (from Full Spectrum), and we were distracted for most of yesterday getting it up and running. So enough excuses - here's this week's batch of links: PVC Instrument, DRS […]
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
