E-ink displays are awesome. Humans spent centuries reading non-backlit devices, and frankly it’s a lot easier on the eyes. But have you looked into driving one of these critters yourself? It&…

When you think about which of the many technological advances of the 20th century had the most impact on the global economy, which one would you rank as the most important? Would it be the space progr...

If you were thinking "I should spend $130 on LEGO bricks and build a giant USB NES controller just to see what that would be like," but you were afraid of spending that much money, [BrownDogGadgets] ...

If you catch a grizzled old radio amateur propping up the bar in the small hours, you will probably receive the gravelly-voiced Wisdom of the Ancients on impedance matching, antenna tuners, and LC net...

What does a hacker do when he or she wants something but can't afford it? They hack one together, of course. Or, in the case of [Ramón Calvo], they thoughtfully plan and prototype. [Ramón Calvo] wan...

[Pen Test Partners] have found some really scary vulnerabilities in AGA range cookers. They are connected by SMS by which a mobile app sends an unauthenticated SMS to the AGA to give it commands fo…

Self-driving cars are, apparently, the next big thing. This thought is predicated on advancements in machine vision and cheaper, better sensors. For the machine vision part of the equation, Nvidia,…

If you've ever been curious if there's a way to program microcontrollers without actually writing software, you might be interested in FlowCode. It isn't a free product, but there is a free demo avail...

New to astrophotography, [Jason Bowling] had heard that the Raspberry Pi’s camera module could be used as a low-cost entry into the hobby. Having a Raspberry Pi B+ and camera module on hand f…

Fair warning: [Justin Atkin]'s video on how to make plasma, fusors, and magnetrons is a bit long. But it's worth watching because he's laying a foundation for a series of experiments with plasma, whi...

Want to know which way to point your WiFi antenna to get the best signal? It’s a guessing game for most of us, but a quick build of a scanning WiFi antenna using mostly off-the-shelf componen…

Security for anything you connect to the internet is important. Think of these devices as doorways. They either allow access to services or provides services for someone else. Doorways need to be s…

We love to see projects undertaken for the pure joy of building something new, but to be honest those builds are a dime a dozen around here. So when we see a great build that also aims to enhance p…

This Saturday is a great day to change the world. It's Earth Day. There's a National March for Science where millions will demand evidence-based change. We're doing our own thing. We're leading a Worl...

Remember all the talk about modular smart phones? They sounded amazing! instead of upgrading your phone you would just upgrade the parts a bit like a computer but more simplistic. Well it seems mod…

Photography is all about light. It's literally right there in the name - stemming from the Greek word, photos. This is why photographers obsess over the time of day of a shoot, why Instagrammers coa...

For most of us, a memory lapse is as harmless as forgetting to bring the garbage to the curb, or maybe as expensive as leaving a cell phone and cup of coffee on the roof of the car before driving o…

Machine shop wisdom says the lathe is the king of machine tools. We ascribe to that belief, although the common aphorism that the lathe is the only tool that can make copies of itself seems a bit o…

3D printing is one of the best things that has happened to the maker community in recent years, however the resulting output has always been prone to damage when used in high temperature applicatio…

When we are introduced to the internals of a microprocessor, it is most likely that we will be shown something like one of the first generation of 8-bit CPUs from the 1970s. There will be the famil…
