A little shaky on IMU selection? This might smooth it out for you.
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?
Want to get started with car hacking? This video is for you!
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!
An updated take on an old classic gag.
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.
How slowly can you clock an ATmega328 and still have any functionality?
I design and build a headphone amplifier, and go on a journey of self-discovery (and learn some hard lessons).
Find out what happens when Pete takes on Big Bluetooth.
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.
What has Pete been up to? Playing with flying robots, actually.
Practice makes perfect...ly acceptable, folks.
He's back, folks!
It's time for another visit with everyone's favorite Director of Engineering!
We've got some fresh "According to Pete" for your viewing pleasure!
I know a guy who is a big "fan" of IoT, even though he's not all that technical. His "day job" is as a business attorney, so he can afford a…
That's true, the blue LEDs would ideally have a resistor closer to 4x than 2x when jumping from 3.3V to 5V. I don't remember my original…
Thanks for your reply! Your "roughly double" resistances for 5V vs 3.3V imply that the difference between LED drop and 3,3V is same as 3,3V…
Your right, that would be a great way to fine tune the current for LEDs! You're also correct that the goal of this project was finding the…
Hi there! For the sake of brevity, I didn't go into full detail about how exactly I calculated the 5V resistor values. But in short, I took…
Responding to your note about the highly non-linear relationship between the pot position and the current -- a way to address this would be…
Nice initiative Dryw! But there's something a bit off in the "5V resistor value" calculations, supposedly using Ohm's law. The forward…
Minor issue: "Today's Deals" is still showing SparkFun Level Shifting microSD Breakout and…
That was fun to watch. Now to figure out how to ship the boards, inexpensively.
The story goes that George Antheil was madly in love with Hedy Lamarr and this was an attempt to gain her interest. There are no documents…
