The Pin Dance
Don’t get me wrong, I love Circuit Python. Sure, I could get stuff done in the ugly stepchild language that is Arduino, but the niggling details, the mediocre IDE, none of it was my friend. And truth to tell, it’s … Continue reading

In praise of cattle
The 16-year-old, who wants a career somewhere in IT, introduced me a while back to the distinction between pets and cattle. When something goes wrong with your pet, you nurse it back to health. When something goes wrong with one … Continue reading
Pedal Assist: Not What I Thought It Was
It’s been a few years since I started wanting an e-bike, but for a long time I was put off by physics. We live at the top of a steep hill, and I’m fat and out of shape. So all … Continue reading

Something actually useful
Our dishwasher is getting to be a certain age. And the plastic parts are showing it. Especially after one of the youth tripped over a cat and onto the bottom rack. When the wheels fall off they have a really … Continue reading
Failing to fail
I’ve been working on and off with Blinkinlabs’ BlinkyTape and pixels, which means also with their nice little app PatternPaint, which lets you create little light shows to download to their LED strands without all the annoying number-fiddling that is … Continue reading
