It wasn't an easy weekend for the rest of the world's hackers and makers, that of the Bay Area Maker Faire. Open your social media accounts, and most of your acquaintances seemed to be there and havin...

[Alex] is no stranger to making machines of negligible utility. A few years ago he made the Almost Useless Machine, a solar-powered system that cuts through a 20mm dowel rod while you wait (and wait,...

Today’s computers are unimaginably complex, and so complicated it’s nearly impossible for anyone to comprehend everything a CPU can do in excruciating detail. It wasn’t always lik…

This is so cool; an unexpected use for an antiquated digital storage medium. [DeepSOIC] built a cutter that shaves off plastics but cannot cut through metal. It’s made out of the media part o…

Last week on the Hacklet we covered optical microscopy projects. Those are the familiar scopes that many of us have at work or even at home on our benches. These are scopes that you typically can use ...

We were trolling around Hackaday.io, and we stumbled on [Barb]'s video series called (naturally enough) "Barb Makes Things". The plot of her videos is simple -- Barb points a time-lapse camera at her ...

If you are a certain age, there were certain science toys you either had, or more likely wanted. A chemistry set, a microscope, a transparent human body, and (one of several nuclear toys) a cloud cham...

Looking for a more unique living experience, [Zach Both] converted a 2003 Chevy Express Van he picked up from Craigslist into a gorgeous mobile home.

The van had 200,000 miles when he bought it. ...

You can drive from Boston to Chicago without picking up a single ticket from a toll booth, or handing money to a single toll booth worker. You can do this because of E-ZPass, a small plastic brick …

What makes the WS2812-style individually addressable pixel LEDs so inviting? Their rich colors? Nope, you can get RGB LEDs anywhere. Their form factor? Nope. Even surface-mount RGBs are plentiful a…

[burgerga] loves attending Music Festivals. He’s also a MechE who loves his LED’s. He figured he needed to put it all together and do something insane, so he build a huge, 15″ geo…

It is not often that you look for one of your heroes on the Internet and by chance encounter another from a completely different field. But if you are a fan of the inimitable silent movie star [Buster...

Hackaday.io contributor extraordinaire [al1] has been playing around with small LEDs a lot lately, which inevitably leads to playing around with large groups of small LEDs. Matrixes of tiny RGB LEDs,...

There are a ton of applications that we use that can benefit from keyboard shortcuts, and we use ’em religiously. Indeed, there are some tasks that we do so often that they warrant their own …

[David] created a great looking e-ink WiFi display project that works a little like a network-connected picture frame with a few improvements over other similar projects. With the help of an ESP826…

The Navy is doing some crazy stuff out in China Lake. They were planning to test something out that could potentially make GPS unusable from San Diego to Las Vegas to San Francisco. Those plans were ...

Within our community of hackers and makers you may sometimes encounter a belief that we have somehow regained a hold on the workshop lost by everyone else. But while it might be true that some of the ...

A stock Arduino isn’t really known for its hi-fi audio generating abilities. For “serious” audio like sample playback, people usually add a shield with hardware to do the heavy li…

We’re not sure we condone this at all. CRT monitors are virtually extinct, and here we have some folks just smashing them up for no good reason. That said, it’s kinda cool to see large …

[Sam Miller], [Sahil Gupta], and [Mashrur Mohiuddin] worked together on a very fast LED matrix display for their final project in ECE 5760 at Cornell University. They started, as any good engineeri…
