[Martin Raynsford] wrote a program that converts a black-and-white 2D image to G-code so that his laser printer could then etch the image. Not satisfied with just that, he used his laser printer to…

You need a coffee table, you need a dinner table. Do you really need two tables? [Shua] thinks the answer is "no". That's why he built this swinging countersink table out of concrete and a aluminum....

Knocking a microcontroller into sleep mode and waking it up on demand or in intervals is common practice in many low power applications, enabling devices to stay in operation for years on a single …

How do you earn a place in a flower festival with a handful of Arduinos and a 3D printer? By building a water curtain that draws flowers. That’s exactly what Tecnoateneu Vilablareix, a hackin…

It’s great to see different kinds of hardware and software tossed into a project together, allowing someone to mix things that don’t normally go together into something new. [Freddy Kil…

When I started boxing classes I was told, at my level, I could do just as much good for my form by doing core exercises such as crunches, running, push-ups, and pull-ups for a month as I could by doin...

At first glance, [Frank Howarth]'s turned bamboo Death Star seems like a straight woodworking project. No Arduino controlled lights, no Raspberry Pi for audio clips of an X-wing attack or escaping TIE...

I was a bit of a lost soul after high school.  I dabbled with electrical engineering for a semester but decided that it wasn’t for me – what I wouldn’t give for a do-over on that …

If you are doing a senior design project in engineering school, it takes some guts to make a robotic duplicate of the school's president. He or she might be flattered, or completely offended. Us? We l...

[Derryn Harvie] from the MakeHackVoid maker space hacked a $10 IR Thermometer and made it talk USB. Sounds easy? Read on. He opened it up in the hope of finding, and tapping into, a serial bus. But…

Have you ever had to write a bit of code to interpret a non-linear analog reading as picked up by an ADC? When all you have to work with for your transfer function is a graph in a semiconductor datash...

[Stefan] works in a place where knowing the exact state of the foreign-exchange market is important to the money making schemes of the operation. Checking an app or a website was too slow and broke h...

Sometimes a project doesn't have to be technically amazing to win over our hearts. [Malte]'s ESP8266-based weather station is so cute, and so nicely executed, that it's easily worth a look. It could t...

We’ve heard reports that internet connectivity in Australia can be an iffy proposition, and [deandob] seems to back that up. At the limit of a decent DSL connection and on the fringe of LTE, …

Can you build a HF SSB radio transciever in one weekend, while on the road, at parts from a swap meet? I can, but apparently not without setting something on fire. Of course the swap meet I’m…

If you want to learn how to defeat computer security, nothing beats hands-on experience. Of course, if you get your hands on someone's system without their permission, you may end up having a very sho...

For the third year in a row, we're running the greatest hardware challenge on the planet. It's the Hackaday Prize, a contest to build something that matters. We're giving away $300,000 to people who ...

At Hackaday, sometimes we nerd out a bit too hard over comic book movies. With Captain America: Civil War in theaters, I knew I had to do a project dedicated to the movie -- so I made a ridiculously o...

There were a lot of very technical talks at Hackaday Belgrade. That's no surprise, this is Hackaday after all. But every once in a while it's good to lift our heads up from the bench, blow away some o...

[MechEngineerMike]'s bike boost is just a pleasure to look at, and, we're certain, a relief to use. While it's not going to rocket you down the street, it will certainly take some of the pain away. (...
