It might not be Pi Day anymore, but Elliot and Dan got together for the approximately 100*Pi-th episode of the Podcast to run through the week’s coolest hacks. Ultrasound seemed to be one of the themes, with a deep dive into finding bugs with sonar as well as using sound to cut the cheese — […]
It doesn’t matter if its a Vespa or a Peterbilt truck — if you ignore the maintenance needs of your vehicle, you do so at your own peril. But it can be difficult enough to keep track of basic oil changes, to say nothing of keeping records on what parts were changed when. Instead of […]
This week, researchers from Wiz Research released a series of vulnerabilities in the Kubernetes Ingress NGINX Controller that, when chained together, allow an unauthorized attacker to completely take over the cluster. This attack chain is known as IngressNightmare, and it affected over 6500+ Kubernetes installs on the public Internet. The background here is that web […]
Radio waves travel fast, and they can bounce, too. If you are able to operate a 25-meter dish, a transmitter, a solid software-defined radio, and an atomic clock, the answer is: yes, they can go all the way to Venus and back. On March 22, 2025, the Dwingeloo telescope in the Netherlands successfully pulled off […]
Scanning a film negative is as simple as holding it up against a light source and photographing the result. But should you try such a straightforward method with color negatives it’s possible your results may leave a little to be desired. White LEDs have a spectrum which looks white to our eyes, but which doesn’t […]
You take your air quality seriously, so shouldn’t your monitoring hardware? If you’re breathing in nasty VOCs or dust, surely a little blinking LED isn’t enough to express your displeasure with the current situation. Luckily, [Tobias Stanzel] has created the AqMood to provide us with some much-needed anthropomorphic environmental data collection. To be fair, the […]
Toaster oven reflow projects are such a done deal that there should be nothing new in one here in 2025. Take a toaster oven, an Arduino, and a thermocouple, and bake those boards! But [Paul J R] has found a new take on an old project, and better still, he’s found the most diminutive of […]
Plastic has been a revolutionary material over the past century, with an uncountable number of uses and an incredibly low price to boot. Unfortunately, this low cost has led to its use in many places where other materials might be better suited, and when this huge amount of material breaks down in the environment it […]
Fake WiFi repeater with a cheap real one behind it. (Credit: Big Clive, YouTube) Over the years we have seen a lot of fake electronics, ranging from fake power saving devices that you plug into an outlet, to fake car ECU optimizers that you stick into the OBD port. These are all similar in that […]
We don’t often get our badminton rackets restrung, but if we did, [kuokuo702]’s PicoBETH project would be where we’d turn. This is a neat machine build for a very niche application, but it’s also a nicely elaborated project with motors, load cells, and even a sweet knobby-patterned faceplate that is certainly worth a look even […]
