As buzzwords go, the “Internet of Things” is pretty clever, and at the same time pretty loathsome, and both for the same reason. “IoT” can mean basically anything, so it&#82…

Many of the hacks featured here are complex feats of ingenuity that you might expect to have emerged from a space-age laboratory rather than a hacker’s bench. Impressive stuff, but on the oth…

2016 is the year of the consumer 3D printer. Yes, the hype over 3D printing has died down since 2012. There were too many 3D printers at Maker Faire three years ago. Nevertheless, sales of 3D print…

Building a marble run has long been on my project list, but now I'm going to have to revise that plan. In addition to building an interesting track for the orbs to traverse, [Jack Atherton] added cu...

How often have you stood in the supermarket wondering about the inventory level in the fridge at home? [Mike] asked himself this question one time too often and so he decided to install a webcam in…

There's nothing better than making a giant version of one of your hacks. That is, other than making it giant and interactive. That's just what [Est] has done with his interactive VU meter that lights ...

Resin-based SLA printers need a different slicing algorithm from “normal” melted-plastic printers. Following their latest hackathon, [Matt Keeter] and [Martin Galese] from Formlabs have…

With cameras, robotics, VR-headsets, and wireless broadband becoming commodities, the ultimate, mobile telepresence system - "Surrogates" if you will - is just one footstep away. And this technology m...

If you’re like us, it’s hard to walk through an Ikea without mentally hacking everything there into something else. The salad bowl? Parabolic antenna. Drawer slides? Linear motion rails…

Einstein referred to her as the most important woman in the history of mathematics. Her theorem has been recognized as “one of the most important mathematical theorems ever proved in guiding …

It’s a really tough problem that has been solved to an amazing level. How do you capture and contain urine from a floppy, curved, and moving human infant? Ah, but the problem is a bit harder …

Sometimes you might need to use assembly sometime to reach your project objectives. Previously I’ve focused more on embedding assembly within gcc or another compiler. But just like some peopl…

Last year, the FCC introduced new regulations requiring router manufacturers to implement software security to limit the power output in specific 5GHz bands. Government regulations follow the laws …

[PWalsh] has a clever idea for learning and experimenting with basic optics: instead of using actual lenses, he’s using clear pieces of laser-cut acrylic cut into lens profiles instead. They …

[Joshua Elsdon] and [Thomas Branch] needed a educational hardware platform that would fit into the constrained spaces and budgets of college classes. Because nothing out there that was cheap, simpl…

The folks at [Design I/O] have come up with a way for you to play the world's tiniest violin by rubbing your fingers together and actually have it play a violin sound. For those who don't know, when y...

Last week was Bsides London, and [Steve Lord] was able to give a talk about the devices that could pass for either a terrible, poorly planned, ill-conceived Internet of Things Kickstarter, or somethin...
