Here’s a fun fact, the kind of thing that you might (but we definitely did not) find out when writing a blog post: Dan Brown actually made up the cryptex for his book, The Da Vinci Code. We t…

[Becky Stern] likes to harness the power of the Sun. Most of us will immediately think of solar cells and other exotic solar energy techniques. But [Becky] shows how to make a hot air balloon using…

If you were a computer-mad teen in the late 1980s, you were probably in the process of graduating from an 8-bit machine to a 16-bit one, maybe an Amiga, or an Atari ST. For the first time though yo…

Rollerblading is fun, but who needs all that pesky exercise? Wouldn’t strapping on the blades be so much more tempting if you had an electric pusher motor to propel you along your way? We hav…

PCI pass through is the ability of a virtualized guest system to directly access PCI hardware. Pass through for dedicated GPUs has just recently been added to the Linux kernel-based virtual machine…

For the last few months, I had been using Sparkfun’s Phant server as a data logger for a small science project. Unfortunately, they’ve had some serious technical issues and have discontinued the se…

Fall – it’s that time of year that brings falling leaves, Hallowe’en, and a pumpkin version of everything that you hold dear. In this case, it’s not a latte – it&#8217…

Hardware teardowns are awesome when guided by experts. One of our favorites over the years has been [Mike Harrison], who has conquered teardowns of some incredibly rare and exquisitely engineered g…

When we think of role models, it’s easy to categorize them narrowly on the basis of their skill set. We might say that he’s a great mathematician, or that she is an excellent chemist. Some ro…

Radio telescopes are one of the dark arts of science. Not only do you have to deal with RF wizardry, the photons you’re detecting are so far out of the normal human experience that you really…

Now that anyone can go online and get a fairly decent 3D printer for around $200, they’ve officially fallen out of the “Elite Hacker” arsenal and are now normal, if perhaps highly…

[jg] recently passed some damaged Braille signs and took on the challenge of repairing them. Informed by his recent work on PCB lapel pins, [jg] immediately thought of using circuit boards for this…

[Ben Krasnow] is known for his clear explanations alongside awesome hardware, being one of only a few hackers who owns an electron microscope. This time he’s explaining how E-paper works whil…

Graphene has attracted enormous interest for electrically detecting chemical and biological materials. However, because the super material doesn’t act like a normal semiconductor, transistors…

When [decino]’s old bedroom clock finally bit the dust, he built himself a new one from scratch for fun and functionality. Initially, he wanted to solder Adafruit NeoPixel lights onto four pr…

Sometimes, you have to call in the experts. [CorSec Props], builders of fine props, costumes and more, were commissioned to replicate Mercy’s healing staff from the game Overwatch. Sounds sim…

There’s a time in every geek’s development when they learn of Conway’s Game of Life. This is usually followed by an afternoon spent on discovering that the standard rule set has b…

For the last few weeks, RC pilot extraordinaire [Peter Sripol] has been working on his biggest project to date. It’s effectively a manned RC plane, now legally a Part 103 ultralight. Now all …

Designing a system for communication over RF is a dark art. It’s an obscure domain filled with photonmancy, wires going every which way, and imaginary numbers. RF is reserved entirely for wiz…
