In the very early days of the PC revolution the only way to have a computer was to build one, sometimes from a kit but often from scratch. For the young, impoverished hobbyist, leafing through the pages of Popular Electronics was difficult, knowing that the revolution was passing you by. And just like that, the […]
It’s often said that “getting there is half the fun”, and we think that can be just as true when building hardware as it is during the roadtrip to your favorite hacker con. Many of us enjoy the process of planning, designing, and building a new gadget as much as playing with it when it’s […]
DEF CON has become the de facto showplace of the #Badgelife movement. It’s a pageant for clever tricks that transform traditional green rectangular circuit boards into something beautiful, unique, and often times hacky. Today I’ve gathered up about three dozen badge designs seen at DC27. It’s a hint of what you’ll see in the hallways […]
For many of us our landscapes are dotted with wind turbines, the vast majority of which are horizontally aligned as if they were giant aircraft propellers. A much rarer sight is the vertical wind turbine, which remains a staple of the wind power experimenter. [Troy] and his brother have posted a video showing a small […]
It seems like hardly a day goes by that doesn’t see some news story splashed across our feeds that has something to do with Elon Musk and one or another of his myriad companies. The news is often spectacular and the coverage deservedly laudatory, as when Space X nails another double landing of its boosters […]
An Israeli start-up company, Redefine Meat recently raisedabout $6 million to perfect and commercialize its technology to 3D print meat alternatives, sometimes called alt-meat. The company claims that producing animal protein for consumption is unsustainable but that their product reduces environmental impact by 95% and has other benefits such as containing no cholesterol and a […]
Classic games consoles played their games from cartridges, plastic bricks that held a PCB with the game code on it ready to be run by the console hardware. You might therefore expect them to be an easy prospect for emulation, given that the code can be extracted from whatever ROM they contain. But as anyone […]
Since the release of the original Raspberry Pi single board computer, the WiringPi library by [Gordon] has been the easy way to interface with the GPIO and peripherals – such as I2C and SPI – on the Broadcom SoCs which power these platforms. Unfortunately, [Gordon] is now deprecating the library, choosing to move on rather […]
Ham radio, especially the HF bands, can be intimidating for aspiring operators, many being put off by the cost of equipment. The transceiver itself is only part of the equation and proper test and measurement equipment can easily add hundreds of dollars to the bill. However, such equipment goes a long way to ease the […]
Fair warning: once you’ve watched [Stephen]’s tiny workshop tour, you will officially be out of excuses for why you need to expand your workshop. And, once you see his storage and organization hacks, you’ll be shamed into replicating some in whatever space you call home. [Stephen]’s woodshop is a cozy 6′ x 8′ (1.8 m […]
