[dmitry] writes in to let us know about a new project that combines lasers with fans and turns the resulting modulation of the light beams into an autonomous soundscape. The piece is ca...

Superhydrophobic coating finds a new application in art through [Arthur Carabott] in the form of a bizarre fountain.

A Master's student in the Global Innovation Design course at the London Royal Co...

The Internet of Things has been presented as the future of consumer electronics for the better part of a decade now. Billions have been invested, despite no one actually knowing what the Internet of T...

[acidbourbon] had some cool parts on hand, and a musician friend in need of a radio-controlled, touch-sensitive MIDI (and analog) controller. This being Hackaday, you can guess what happened next.

McDonald’s is serious about their fries. When they were forced by shifting public opinion (drunkenly swaggering around as it always does) to switch from their beef tallow and cottonseed oil m…

[Rafael] made a sweet little retro watch that’s a fantastic introduction to hardware DIY. If you’ve programmed an Arduino before, but you’ve never had a board made, and you are up…

One of the most ingenious developments in test and measuring tools over the last few years is the Mooshimeter. That's a wireless, two-channel multimeter that can measure voltage and current simultaneo...

I start each day checking out the new and updated projects over on Hackaday.io. Each day one can find all manner of projects - from satellites to machine vision to rockets. One type of project which i...

[Daiju Ishikawa] wrote us to announce that the world championship Hebocon is taking place this August in Tokyo, and the registration has just opened. When you get a mail in the tip line that reads "Fr...

Numbers are wonderful things when applied to technical specifications. Take [Bobricius]' handheld Arduino-based game console. With an 8x8 LED matrix for a display it's not going to win any prizes, but...

Software-defined radio (or SDR) is a relatively new (to average tinkerers, at least) way of sending and receiving radio signals. The interest in SDR exploded recently with the realization that cheap U...

If there's one place where the Internet of Things makes sense, it's agriculture. From vast fields of soybeans, corn, and a different variety of corn, to the backyard garden, knowing how much sun, and...

[Evan] always wanted a trackball for his arcade cabinet. It's hard to play Missile Command with anything else, and Centipede with any other controller is just stupid. So he bought one, jury-rigged a m...

The heroes of action films always make it look so easy. Need to climb a tall building? Simply fire a grapnel hook from a handy harpoon gun, it’ll always land exactly where you want it and gai…

The Xerox Alto was a minicomputer that had a lot of firsts to its name: first GUI, first Ethernet connection, and first computer to use a laser printer. This is the computer that inspired Steve Jobs t...

It always surprises us that magnetic levitation seems to have two main purposes: trains and toys. It is reasonably inexpensive to get floating Bluetooth speakers, globes, or just floating platforms fo...

[Harris Shallcross] decided to build a pair of smart glasses and recently completed a first prototype of his project ‘Ochi’ – an STM32 based, BLE-connected, OLED eyeglass display.…

[Nick Sayer] can reflow, and he can prove it. He designed a simple blinking-LED circuit that uses SMD parts to, well, blink LEDs. That's not the point, though. It's designed to be a test platform for ...

Solar Freaking Roadways. What is it? It's technology that replaces all roadways with a smooth sheet of glass and solar panels. You know how asphalt is soooo easy to repair and soooooo cheap? Yes...

If you need to generate a radio frequency electrical signal, you will make some form of electronic oscillator. We’ll probably all be used to oscillators using transistors, tubes, logic gates …
