When we see an extremely DIY project, you always get someone who jokes “well, you didn’t collect sand and grow your own silicon”. [Patrícia J. Reis] and [Stefanie Wuschitz] did the next best thing: they collected local soil, sieved it down, and fired their own clay PCB substrates over a campfire. They even built up […]
While many in the industry were at first skeptical of NASA’s goal to put resupply flights to the International Space Station in the hands of commercial operators, the results speak for themselves. Since 2012, the SpaceX Dragon family of spacecraft has been transporting crew and cargo from American soil to the orbiting laboratory, a capability […]
As you might expect, the University of Puerto Rico at Arecibo has a fascination with radio signals from space. While doing research into the legendary “Wow! Signal” detected back in 1977, they realized that the burst was so strong that a small DIY radio telescope would be able to pick it up using modern software-defined […]
The way to get into radio, and thence electronics, in the middle years of the last century, was to fire up a shortwave receiver and tune across the bands. In the days when every country worth its salt had a shortwave station, Cold War adversaries boomed propaganda across the airwaves, and even radio amateurs used […]
It’s not often that Hackaday brings you something from a cooking channel, but [I Want To Cook] has a fascinating look at Pyrex glassware that’s definitely worth watching. If you know anything about Pyrex it’s probably that it’s the glass you’ll see in laboratories and many pieces of cookware, and its special trick is that […]
WiFi is an excellent protocol, but it certainly has its weaknesses. Its range in even a normal home is relatively limited, so you could imagine the sort of performance you’d expect through the hundred meters of dense woodland that [DO3RB] is trying to penetrate. So naturally the solution was to develop a new wireless transceiver for […]
Radio experimenters often need a variable capacitor to tune their circuits, as the saying goes, for maximum smoke. In decades past these were readily available from almost any scrap radio, but the varicap diode and then the PLL have removed the need for them in consumer electronics. There have been various attempts at building variable […]
Is 2025 finally the year of non-planar 3D printing? Maybe it won’t have to be if [Ten Tech] gets his way! Ironing is the act of going over the top surface of your print again with the nozzle, re-melting it flat. Usually, this is limited to working on boring horizontal surfaces, but no more! This […]
This week Jonathan and Rob chat with Tom Herbert about XDP2! It’s the brand new framework for making networking really fast, making parsers really simple, and making hardware network acceleration actually useful with Linux. https://medium.com/@tom_84912/xdp2-this-changes-everything-at-least-for-ai-ml-infrastructure-850c1ba82771 https://medium.com/@tom_84912/programming-a-parser-in-xdp2-is-as-easy-as-pie-8f26c8b3e704 Did you know you can watch the live recording of the show right on our YouTube Channel? Have someone […]
