[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 …

Use of the global positioning system is all around us. From the satnav in your car to quadcopters hovering above a point, there are hundreds of ways we use the Global Positioning System every day. …

We’ve covered [Vijay] refreshable braille display before. Reader, [zakqwy] pointed us to an interesting event that occured in the discussion of its Hackaday.io project page. [Vijay] was inspi…

We’re glad we’re not the only hacker-packrats out there! [Voja Antonic] recently stumbled on an EPROM emulator that he’d made way back in 1991. It’s a sweet build, so take y…

In 1988, a bunch of engineers from Hotzenwald, East Germany, came together and decided that it is time for the future of mobility: A new, more modern and environmentally friendly car should put an en...

[John Fin] put a lot of work into his Ghostbuster's proton pack prop with full-featured user control and effects. What appealed to us well beyond the exquisite build is the extra effort taken to wri...

Killer robots are a mainstay of science fiction. But unlike teleportation and flying cars, they are something that we are likely to see within our lifetime. The only thing that's stopping countries li...

There’s an old adage that when performing a live demo, previously working hacks will mysteriously go awry. In this case, the hardware demo was doomed before it ever arrived at the conference.…

After his death, Aaron Swartz became one of the Internet’s most famous defenders of the free exchange of information, one of the most polarizing figures on the topic of intellectual property,…
