Tired of paying The Man for your power? Before you go off-grid, this is the video you want to see. We'll give you the background on solar cell function and performance, and talk about some of the other parts you'll need to get the job done.
Care to take a peek under the hood of reality? Hall effect and Lorentz force are big news in the land of the tiny.
We tend to over-simplify the act of dropping an LED into a circuit. But do you know what all of those specs in the data sheet mean?
Heard about CAN bus but don’t know what all the hype is about? This video’s for you!
Looking for a beefy, wired data bus where RF won’t cut it? We dig into RS-485 and explore how it works and why it just might be the one you need!
Without phase-locked loops, we’d all still be living in caves, just getting by with stone knives and bearskins.
To honor our 15th anniversary, Pete digs into the electrical properties of crystals.
I design and build a headphone amplifier, and go on a journey of self-discovery (and learn some hard lessons).
Pete digs into WiFi for a broad, hardware-ish level explanation of how it all works.
There's so much arguing over code on the internet. Let's try to get to the bottom of the debate.
