Computers and cellphones can do so many things, but sometimes if you want to doodle or take a note, pencil and paper is the superior technology. You could carry a device and a pocket notebook, or you could combine the best of analog and digital with the KeyMo. [NuMellow] wanted a touchpad in addition to […]
After World War II, as early supersonic military aircraft were pushing the boundaries of flight, it seemed like a foregone conclusion that commercial aircraft would eventually fly faster than sound as the technology became better understood and more affordable. Indeed, by the 1960s the United States, Britain, France, and the Soviet Union all had plans […]
There are a ton of Bluetooth speakers on the market. Just about none of them have any user-serviceable components or replacement parts available. When they break, they’re dead and gone, and you buy a new one. [Jonathan Mueller-Boruttau] wrote in to tell us about the latest speaker from Teufel Audio, which aims to break this cycle. […]
Recently the [Global Science Network] released a video of using an artificial brain to control an RC truck. The video shows a neural network comprised of eight artificial neurons assembled on breadboards used to control a fully autonomous toy truck. The truck is equipped with four proximity sensors, one front, one front left, one front […]
Yes, the Wireless Application Protocol! What other WAP could there possibly be? This long-dormant cellphone standard is now once again available on the web, thanks to [Sean] over at ActionRetro modifying his FrogFind portal as a translation engine. Now any web site can be shoved through the WAP! WAP was rolled out in 1999 as […]

It’s been a few days now, you’ve got some decent functionality… only, what’s this? The AI is telling you it screwed up. It ignored what you said and wiped the database, and […]
What can you do with a laptop enough to drink even in the Puritan ex-colonies? 21 years is a long time for computer hardware– but [Chris] is using his early-2004 iBook G4 for game dev thanks to NetBSD. Some of you might consider game dev a strong word; obviously he’s not working on AAA titles […]
One of the earliest commercially-successful camera technologies was the rangefinder — a rather mechanically-complex system that allows a photographer to focus by triangulating a subject, often in a dedicated focusing window, and and frame the shot with another window, all without ever actually looking through the lens. Rangefinder photographers will give you any number of […]
We’ve seen our share of blinking light projects around here; most are fairly straightforward small projects, but this entry to the 2025 One Hertz Challenge is the polar opposite of that approach. [Peter] sent in this awesome tower of 16bit relay CPU power blinking a light every second. There’s a lot to take in on […]
