[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,…

3D printers were never meant to be used for production. They’re not manufacturing machines, they’re prototyping machines. That doesn’t mean 3D printers can’t be used in a ma…

Looking for a quick DIY project to separate yourself from the crowd at your next business function or maker expo? Take a leaf out of [Pete Prodoehl's] book and make your own name tag complete with bli...

We live in a connected world, but that world ends not far beyond the outermost cell phone tower. [John Grant] wants to be connected everywhere, even in regions where no mobile network is available,…

Get ready to rumble! [Thierry] made the exact same Hello-World-esque project with two microcontrollers (that are now technically produced by the same firm!) to see how the experience went. It&#8217…

The Raspberry Pi and other similar Linux-based single board computers simplify many projects. However, one issue with Linux is that it doesn't like being turned off abruptly. Things have gotten better...

I know you’ve heard of both synchronous and asynchronous communications. But do you really know the differences between the two? Serial communication was used long before computers existed. A…

It's been a long time since we've logged into a UNIX mainframe (other than our laptop) but one of our fond memories is the daily fortune: small, quirky, sometimes cryptic sayings that would pop up on ...

Computer graphics have come a long way. Some video games today exceed what would have passed for stunning cinema animation only a few years ago. However, it hasn’t always been like this. One …
