Circuit: Stepper Motor

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

Tech Tip: Micro Terminal Blocks

We use many, many devices with 0.1" spaced holes, which are pretty much an electronics design standard. We're finding these 0.1" space terminal blocks incredibly useful for making solid, secure, yet serviceable connections to the rest of our designs. We'll often reach for a microcontroller board, then reach for a necessary handful of these parts […]

Frogbots! Solar-powered, at that!

I missed the full segment of this story last weeks on "Discovery Channel's @discovery.ca" program, but fortunately, the've put the segment online at their website. I seems that JPL (Jet Propulsion Laboratories - NASA essentially) is working on a solar-powered, single-footed robot frog. This seems like a GREAT idea for extra-terrestrial planet-surface locomotion. Check out […]

Metal Spinning Field Trip

We've been researching a manufacturer for a shiny new product we are working on (shhh, don't tell anyone and stay tuned for the reveal!). What we have been looking for is a metal spinner. Metal spinning, also known as spin forming, spinning, or metal turning most commonly, is a metalworking process by which a disc […]
