Photography turntables are made for both the precise and lazy. Whether you are concerned about the precision of consistent angles during a photo shoot or you simply do not want to stand there rotat…

The Egg Drop is a classic way to get students into engineering, fabrication, and experimentation. It’s a challenge to build a container to protect a raw egg from cracking when dropped from va…

[James], aka [Turbo Conquering Mega Eagle], is not your typical Hackaday poster boy. Most of his builds have a  “Junkyard Wars” vibe, and he’d clearly be a good man to have around…

Around the Hackaday secret bunker, we’ve been talking quite a bit about machine learning and neural networks. There’s been a lot of renewed interest in the topic recently because of the…

Linux audio may be confusing for the uninitiated. As a system that has evolved and spawned at least two independent branches over time it tends to produce results that surprise or irritate the user…

We all know the saying: cheap, fast, or good — pick any two. That rule seems to apply across the spectrum of hackerdom, from software projects to hardware builds. But this DIY Tesla coil buil…

Polio was a disease that devastated the United States in the 1950s, but with concerted efforts towards vaccination, is now on the verge of eradication. With the disease a distant memory for most, i…

We admit it, we have a nostalgic soft spot for ASCII Art. Pictures made form characters, printed on an old-fashioned line printer. They’ve been a hacker standby since the 1960’s. Times …

At first glance, [Dean Gouramanis]’s stepper driver module for 3D printers looks like just another RAMPS-compatible stepper board. Except, what could that brass peg sticking out of the PCB po…

There’s an inside joke among cyclists – the number of bikes you need is “n+1”, where “n” is your current number of bikes. The same probably also applies to the n…

Long before things “went viral” there was always a few “must have” toys each year that were in high demand. Cabbage Patch Kids, Transformers, or Teddy Ruxpin would cause vir…

[Allan Schwartz] decided to document his experience using Fritzing to design, fabricate, and test a custom Arduino shield PCB, and his step-by-step documentation makes the workflow very clear. Anyo…

The holiday season is upon us, so you know what that means. It’s time to consume! Whether that means large quantities of carbohydrates or consumer electronics, ’tis the season to buy, b…

Tracking satellites and the ISS is pretty easy. All you really need is an SDR dongle or a handheld transceiver, a simple homebrew antenna, and a clear view of the sky. Point the antenna at the pass…

The TS100 is a compact temperature-controlled soldering iron that’s long on features without too eye-watering a price. One thing it lacks as shipped though is anything to protect it from the …

Hey, it’s sometime between Black Friday and Cyber Monday. We’re blowing out everything in the Hackaday Store. There’s some great deals in there. Tindie, our lovable robot dog is a…

Simple to learn, hard to master, a lifetime to kick the habit. This applies to a lot of computer games, but the T-rex Runner game for Chrome and its various online versions are particularly insidio…
