When you think of tracked robots, you might think of bomb disposal robots or others used in military applications. You probably haven’t seen anything quite like this, however—it’s a “reconfigurable continuous track robot” from researchers [Tal Kislasi] and [David Zarrouk (via IEEE Spectrum). Neat party trick! The robot looks simple, like some kind of tracked […]
Radar made a huge impact when it was first invented, allowing objects to be detected using radio waves which would normally be difficult or impossible to observe through other means. Radio waves of all frequencies can be used for radar as well, whether that’s detecting ships beyond the horizon, tracking aircraft near an airport, penetrating […]
There was a time in the not-too-distant past when magnetic tape was the primary way of listening to and recording audio. Most of us are familiar with the cassette tape, a four-track system that plays first one side of the tape, then the other. There was the eight-track tape as well which did not have […]
Although quantum processors exist today, they are still a long way off from becoming practical replacements for classical computers. This is due to many practical considerations, not the least of which are factors such as the need for cryogenic cooling and external noise affecting the system necessitating a level of error-correction which does not exist […]
The proliferation of microcontrollers has made it easier than ever to add some smarts to a project, but sometimes there just isn’t enough space for headers on a board, or you feel a little silly soldering something that will get used to flash a program then languish inside your build. [Dima] wanted to make his […]
Erratum RP2350-E9 in the RP2350 datasheet, detailing the issue. The newly released RP2350 microcontroller has a confirmed new bug in the current A2 stepping, affecting GPIO pull-down behavior. Listed in the Raspberry Pi RP2350 datasheet as errata RP2350-E9, it involves a situation where a GPIO pin is configured as a pull-down with input buffer enabled. […]
This week Jonathan Bennett and Rob Campbell chat with Carl Richell about System 76, COSMIC, Wayland, Rust and more! What was the “last straw” that convinced System 76 to write their own desktop environment (DE)? What’s the story with smithay, and why did that jump start the whole process? Listen to find out! https://system76.com/cosmic Did […]
Some of the neatest products are made from the byproducts of other industries. Take petroleum jelly, for example. Its inventor, Robert Chesebrough, a chemist from New York, came upon his idea while visiting the oil fields of Titusville, Pennsylvania in 1859. It took him ten years to perfect his formula, but the product has been […]
The chiptune scene is dominated by Game Boys and other Nintendo hardware, but one should never forget the gorgeous, beautiful tones that come from the hallowed Commodore 64. [Linus Åkesson] knows this well, and it’s at the heart of his work on the Commodordion. Now, he’s built an even better version. The original idea he […]
Usually, when you need to sense something in a project, the answers are straightforward. Want to sense air temperature? There’s a sensor for that. Particulate content in the air? There’s a sensor for that, too. Someone sneaking up on you? Get yourself some passive infrared sensors (PIRs) and maybe a smart camera just to be […]
