A decent website is a core of a web-centric store like ours. Back in the early days, I hand-coded HTML (yeah, go back to waybackmachine to admire that work), and what you got is what you got. Since then, we rebuilt Solarbotics.com through 3 more iterations of totally refactored hand-coded platforms, and then 2 aborted […]
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

Solarcell Analysis - part 1
We've been working on testing our Sunceram Solarcells for real-world performance. Our first test is under direct sunlight, and we tried our best to get accurate data under ideal conditions - summer solstice, during the brightest hours of the day. As we're located in Calgary (lat:51.050N), Canada, you may get slightly different results due to […]
YaaHOO! Stampede & GM11's!
Yup, it's that time of the year in Calgary, pahdnah (no, that's not an East Indian name - it's cowboy for friend). The Calgary Stampede is upon us, and we're expecting to give our staff a wee bit of leeway to enjoy themselves a bit. It shouldn't affect your service, but don't be surprised if […]
No, it isn't $30...
Sorry about that. The last ad for the ARDX Experimenter's Kit for Arduino? Wrong. Our graphics designer, Chris (yes, I'll give credit where credit is due) used an old template for our latest Servo Advertisement, and didn't change the price. No, it's not $30 - it's still $84.95USD. And continuing the blame-game, I gave him […]
