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.

Just noticed that the serial header is SMD. I’d be inclined to make it PTH, as this is something that can be susceptible to some stress, and…
Without knowing the range of use cases, can’t say for sure if it is a flaw. The thing I noticed was that you used fairly large power MOSFETs…
Strapping to connect the level shifter to V1 or V2?
I’m not sure if this is the case, but it almost looks like there are a few isolated ground planes around the power supply region.
I would second the usefulness of ham radio in this endeavour. With the right license and equipment the HF/MF/LF bands are accessible, and…
That might be just a bad picture/angle. There are several pins that have that same dark spot that looks like a hole where there should be…
I’m assuming the bottom left-most header pin isn’t soldered to the board for a reason? That seems more like an assembly error than a board…
Playing “Devil’s Advocate”, I’m curious about how you test the Pi AVR Programmer Hat (since it’s…
Although dksmall caught that the silkscreen has values rather than designators (for a design this small, I’m OK with that), there are at…
