If we’ve learned anything, it’s that 3D printers are exceptionally well suited to printing little boats. According to the Internet, 3D printers are at their best when pumping out cute P…

For this week’s Hack Chat, we’re going to be talking all about FPGAs, with our own resident FPGA expert. This summer, Hackaday.io launched FPGA bootcamps, simple, easy-to-follow tutoria…

There’s a certain minimum set of stuff the typical Hackaday reader is likely to have within arm’s reach any time he or she is in the shop. Soldering station? Probably. Oscilloscope? May…

We just wrapped up the Musical Instrument Challenge in the Hackaday Prize, and that means we’re sorting through a ton of inventive electronic musical instruments. For whatever reason we can&#…

Even if you aren’t a vintage computer aficionado, you’re probably aware that older computer hard drives were massive and didn’t hold much data. Imagine a drive that weighs several…

Sure, you can buy a cable tester, but what fun is that? [Ashish] posted a nice looking cable tester that you can build with or without an onboard Arduino. If you don’t use an Arduino, the pro…

Most humans take a year to learn their first steps, and they are notoriously clumsy. [Hartvik Line] taught a robotic cat to walk [YouTube link] in less time, but this cat had a couple advantages ov…

With its introduction in 1989, the Atari Lynx was the first handheld videogame system to include a color LCD. The gigantic size and equally gigantic price tag did not win-over a massive audience, b…

A property of radio waves is that they tend to reflect off things. Metal surfaces in particular act as good reflectors, and by studying how these reflections work, it’s possible to achieve al…

The breadboard microcontroller experimenter has a host of platforms to work with that can be had in the familiar DIP format. Old-school people can still find classic 8-bit platforms, the Ardunisti …

NASA spokesperson [Brandi Dean] summarized it succinctly: “Confirming again that today’s Soyuz MS10 launch did go into ballistic re-entry mode … That means the crew will not be go…

The future is upon us and the robots will soon take over. Automated cars will put Uber drivers and cabbies alike out of work. Low-wage workers, like the people working behind the counter at McDonal…

We’ve all seen a movie or TV show that got our imagination going, and the more studious of us might get fired up over a good book (one without pictures, even). You never know were inspiration…

Reverse engineering silicon is a dark art, and when you’re just starting off it’s best to stick to the lesser incantations, curses, and hexes. Hackaday caught up with Ken Shirriff at la…

Today’s failed Soyuz launch thankfully resulted in no casualties, but the fate of the International Space Station (ISS) is now in question. Just two minutes after liftoff, the crew of the Soy…

The people who make neon signs are a vibrant community with glass bending and high voltage electronics. There is a need, though, to sequence these neon signs, and it seems like MIDI is the way to d…

It might not be obvious unless you’ve taken one apart, but most of the TVs and monitors listed as “LED” are simply LCD panels that use a bank of LEDs to illuminate them from behin…

Professional or amateur, doing things the hard way doesn’t always make for better results. Take photography as an example. Once upon a time, the success or failure of what happened during the…

It’s a reasonable certainty that 3D-printing is one day going to be a huge part of medicine. From hip implants to stents that prop open blood vessels to whole organs laid down layer by layer,…

When it comes to power tools, generally speaking more watts is better. But as laser maestro [Martin Raynsford] shows, watts aren’t everything. He shares a brief video showing his older 100 W …
