  • While I do enjoy Qi (And TIL that Bill Baley is good at running backwards… I hadn’t seen that episode), I take some of their facts with a grain of salt, as it’s primarily an entertainment show. They do tend to oversimplify and miss some nuance from time to time.

    Just as an example, one such case was in regards to flight theory, where the correct answer to “how do planes fly” was “nobody knows”. While there isn’t a grand unifying theory that describes flight theory in full, we do have a lot of individual concept that describe 99.9% of how flight works. It’s like saying “nobody knows” in regards to why the earth orbits the sun on the basis that we don’t have a unifying theory between quantum field theory and gravity.

    I’m not disparaging Qi, though. It’s still a fantastic show, but it’s meant to be entertaining rather than complete.

    EDIT: Yes, “Qi”, not “Windows”. Ducking autocorrect.















  • I got back into hobby electronics after life getting in my way for 20ish years. And wow things are a lot more available and out of the box than before.

    Lately I’ve been getting into I²C peripherals. They’re pretty cheap too. Wanna build an X that does Y? Adafruit probably has some breakout board for you that does what you need. Hook it up to your platform of choice (Raspberry pi, arduino, etc etc) via four wires (well, 2… I just run power from a raspberry pi as well) and you’re good to go.

    Optional: Combine it with a 3D printer to make chassis and mounting platforms.

    I now have a raspberry pi that knows its absolute orientation, altitude, and position. I’m currently working on PWM input for receiving inputs from an RC radio I happened to have. After that it’s PWM output to control servos. I might build it into a semi autonomous RC plane/drone or similar. We’ll see where this project takes me.
