Once a car passes that 15 year milestone, suddenly manufacturer support can start […]
[Nick Chen] shared some fascinating and useful details about building a AN/PVS-14 monocular night vision device from parts. It’s not cheap, but the build would be a simple one for most Hackaday readers, at least the ones who are residents of the USA.

If you’re looking to make money in electronics, there’s no better market than guitar pedals and modular synths. The margins are high, and all the consumers are otakus who will spend outrageous amounts of money chasing the next big thing.

Microcontrollers are cool, but sometimes the user interface options they can deliver are disappointing. The platform in question may not have the horsepower required to drive a decent screen, and often a web interface is undesirable for security or complexity reasons. Sometimes you just need a good software interface between chip and computer. Firmata is […]
It wasn’t long ago that graphene seemed to take the science and engineering communities by storm. You can make bits of it with a pencil and some sticky tape, yet it had all sorts of wonderful properties. The key, of course, is that it is a single layer of atoms. Now scientists have done the […]
Visitors to the Wizarding World of Harry Potter at Universal Studios are able to cast “spells” by waving special interactive wands in the air. Hackers like us understand that there must be some unknown machinations happening behind the scenes to detect how the wands are moving, but for the kids wielding them, it might as […]
If you want to display numbers, just go for Nixies. There’s no better way to do that job, simply because they look so cool. Unfortunately, Nixies require high voltages, controlling them is a tiny bit strange, and they suck down a lot of power. These facts have given us a few Nixie alternatives, and [Dave] […]
What prosthetic limbs can do these days is nothing short of miraculous, and can change the life of an amputee is so many ways. But no matter what advanced sensors and actuators are added to the prosthetic, it has to interface with the wearer’s body, and that can lead to problems. Measuring and mapping the […]
The increase in network-connected devices the past years has been something of a dual-edged sword. While on one hand it’s really nice to have an easy and straight-forward method to have devices talk with each other, this also comes with a whole host of complications, mostly related to reliability and security. With WiFi, integrating new […]
