CircuitPython for early hardware exploration

I’d expected the software side of using CircuitPython chips to go more easily than coding in Arduino, but what I hadn’t really expected was for the hardware side to go more smoothly as well. It’s early yet, and most of … Continue reading

Cooperative Editing whether you want it or not

The last time I tried teaching some kids how to program arduinos, the room we were in had no wifi to speak of. Getting working copies of the desktop IDE onto half a dozen ancient underpowered windows laptops was a … Continue reading

Arduino on Windows: not ready for prime time

I’ve been teaching a little middle-school mobile robot workshop at the 12-year-old’s school, and it’s been a mess. The kids did pretty well assembling the bots and wiring them up, but clearly I needed to spend much more than the … Continue reading

Progress is Bad

I’ve been working for a while on a wearable accelerometer/datalogger project, and I came up with a nice breadboard prototype using a spare Seeduino Stalker plus a bunch of other parts. But that’s kinda big to actually wear. Next up: … Continue reading

Blinkinlabs Rocks

I’ve liked Blinkytape ever since it came out. Sure, you can hook up LED strips with an arduino or whatever easily, but sometimes having the controller built into the tape just makes things so much easier no wiring, no mounting, … Continue reading

Belt and suspenders

I really like the idea of Yourduino’s RoboRed: gobs of 3-pin headers for almost all the arduino I/O pins, with n-tuplicated power and ground connections. Heavy-duty regulators built in for two amps of 5V and half an amp of 3V3 … Continue reading

True North

Well, except for declination error and any nearby metal objects, and within the resolution of the stepper motor… Ingredients: Adafruit 9-degree-of-freedom accelerometer/gyro/magnetometer, wired through a slip ring to an Arduino clone with lots of spare 5-volt power, driving one of … Continue reading
