CircuitPython for early hardware exploration

Posted on April 3, 2019 by paulwallich

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

Posted on January 7, 2018 by paulwallich

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

Posted on July 10, 2017 by paulwallich

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

Posted on February 1, 2016 by paulwallich

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

Posted on December 21, 2015 by paulwallich

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

Posted on November 17, 2015 by paulwallich

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

Posted on November 1, 2015 by paulwallich

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 →

Yet another tiny robotic car

Posted on September 9, 2015 by paulwallich

Yes, it’s made mostly out of random parts I had lying around. That’s sort of the point: even if you had to buy all the parts, this thing would be cheap, and if (like me) you accumulate toy and electronic … Continue reading →

Nasty things, adventures

Posted on March 18, 2015 by paulwallich

When my freshman-year college roommate was in medical school, he told me that surgeons were trained to say “There!” instead of “Oops” when they made a mistake like cutting the wrong organ, so as not to panic everyone around them. … Continue reading →
