Almost all entry-level physics courses, and even some well into a degree program, will have the student make some assumptions in order to avoid some complex topics later on. Most …read more Continue reading Remote-Controlled Hypercar Slices Through Air
The operational amplifier, or op amp, is one of the most basic building blocks used in analog circuits. Ever since single-chip op amps were introduced in the 1960s, thousands of …read more Continue reading From Nanoamps to Gigahertz: The World’s Most Extreme Op Amps
Forget your friendly little electric air taxis. The US Air Force wants to take things up a notch with a new generation of high-speed vertical takeoff and landing aircraft. Thirty five designs are about to be presented, here’s a sneak peek at the ones w… Continue reading US Air Force set to showcase 35 high-speed VTOL aircraft concepts
Man stands next to car and talks about it: it’s a video format you’ve seen a thousand times. It does hit a bit different, though, when the guy’s own name is on the back of the car. Christian Von Koenigsegg is one of a very short list of people who have… Continue reading Mr. Koenigsegg thrashes the Jesko “megacar” and its remarkable gearbox
Placing two motors together in a shared drive is a simple enough task. By using something like a chain or a belt to couple them, or even placing them on …read more Continue reading Differential Drive Doesn’t Quite Work As Expected
A lot of us have nostalgia for our childhood toys, and as long as they’re not something like lawn darts that nostalgia often leads to fun upgrades since some of us are adults with industrial-sized air compressors. Classics like Super …read more
If you play with high speed design for long enough, eventually you’re going to run into clock skew and other weird effects. [Robert Feranec] recently ran into this problem and found an interesting solution to visualizing electric fields in a PCB.
A word of warning before we dig into this, …read more
Designing circuit boards for high speed applications requires special considerations. This you already know, but what exactly do you need to do differently from common board layout? Building on where I left off discussing impedance in 2 layer Printed Circuit Board (PCB) designs, I wanted to start talking about high speed design techniques as they relate to PCBs. This is the world of multi-layer PCBs and where the impedance of both the Power Delivery Network (PDN) and the integrity of the signals themselves (Signal Integrity or SI) become very important factors.
I put together a few board designs to test …read more

Debugging with printf is something [StorePeter] has always found super handy, and as a result he’s always been interested in tweaking the process for improvements. This kind of debugging usually has microcontrollers sending messages over a serial port, but in embedded development there isn’t always a hardware UART, or it might already be in use. His preferred method of avoiding those problems is to use a USB to Serial adapter and bit-bang the serial on the microcontroller side. It was during this process that it occurred to [StorePeter] that there was a lot of streamlining he could be doing, and …read more
