After Years Of Uncertainty, Stratolaunch Flies Again

When Paul Allen founded Stratolaunch in 2011, the hope was to make access to space cheaper and faster. The company’s massive carrier aircraft, the largest plane by wingspan ever to be built, would be able to carry rocket-powered vehicles up into the thin upper atmosphere on short notice under the power of its conventional jet […]

Electric Vehicle 1900’s Style: New Leases On Old Tech

Excited about your new electric vehicle? Thomas Edison would be, too. He tried to produce electric vehicles for Ford around 1900. Petroleum-based vehicles dashed his dreams of the electric car, and the battery he wanted to use languished as a technological dead end. The batteries were long-lasting, sure, but they were expensive and had other […]

Hackaday Links: April 4, 2021

Can I just say that doing a links roundup article in a week that includes April Fool’s Day isn’t a fun job? Because it’s not. I mean, how can you take something like reports of X-rays flowing from Uranus seriously when they release the report on such a day? It sure looks like a legitimate […]

Hershey Fonts: Not Chocolate, The Origin Of Vector Lettering

Over the past few years, I kept bumping into something called Hershey fonts. After digging around, I found a 1967 government report by a fellow named Dr. Allen Vincent Hershey. Back in the 1960s, he worked as a physicist for the Naval Weapons Laboratory in Dahlgren, Virginia, studying the interaction between ship hulls and water. […]

Putting Your Time In | Hackaday

I was absolutely struck by a hack this week — [Adam Bäckström]’s amazing robot arm built with modified hobby servos. Basically, he’s taken apart and re-built some affordable off-the-shelf servo motors, and like the 6-Million-Dollar Man, he’s rebuilt them better, stronger, faster. OK, and smoother. We have the technology. The results are undeniably fantastic, and […]

Retrotechtacular: CT2, When Receiving Mobile Phone Calls Wasn’t A Priority

Over the years we’ve brought you many examples in this series showing you technologies that were once mighty. The most entertaining though are the technological dead ends, ideas which once seemed as though they might be the Next Big Thing, but with hindsight are so impractical or downright useless as to elicit amazement that they […]

The Politics Of Supersonic Flight: The Concord(e)

Every nation has icons of national pride: a sports star, a space mission, or a piece of architecture. Usually they encapsulate a country’s spirit, so citizens can look up from their dreary lives and say “Now there‘s something I can take pride in!”  Concorde, the supersonic airliner beloved by the late 20th century elite for […]

New Parts, New Hacks | Hackaday

The biggest news this week is that Raspberry Pi is no longer synonymous with single-board Linux computers: they’re dipping their toes into the microcontroller business with their first chip: the RP2040, and the supporting breakout board, the Pico. It’s an affordable, capable microcontroller being made by a firm that’s never made microcontrollers before, so that’s […]

Teardown: Tap Trapper | Hackaday

The modern consumer is not overly concerned with their phone conversations being monitored. For one thing, Google and Amazon have done a tremendous job of conditioning them to believe that electronic gadgets listening to their every word isn’t just acceptable, but a near necessity in the 21st century. After all, if there was a better […]

Bare-Metal STM32: Universal, Asynchronous Communication With UARTs

One of the most basic and also most versatile communication interfaces on an MCU is the UART, or Universal Asynchronous Receiver/Transmitter. Usually found in the form of either a UART or USART, the former allows for pure asynchronous serial communication, whereas the latter adds flow control. When working with MCUs, they’re also one of the […]

Remoticon Video: The Mechanics Of Finite Element Analysis

Hardware hacking can be extremely multidisciplinary. If you only know bits and bytes, but not solder and electrons, you’re limited in what you can build. The same is true for mechanical design, where the forces of stress and strain suddenly apply to your project and the pile of code and PCBs comes crashing to the […]

Remoticon Video: From Zero To ASIC; How To Design In Silicon

Designing your own integrated circuits as a one-person operation from your home workshop sounds like science fiction. But 20 years ago, so did rolling your own circuit boards to host a 600 MHz microcontroller with firmware you wrote yourself. Turns out silicon design isn’t nearly as out of reach as it used to be and […]

Remoticon Video: How To Use Max In Your Interactive Projects

When you want to quickly pull together a combination of media and user interaction, looking to some building blocks for the heavy lifting can be a lifesaver. That’s the idea behind Max, a graphical programming language that’s gained a loyal following among anyone building art installations, technology demos (think children’s museum), and user Kiosks. Guy […]

Hackaday Links: December 13, 2020

Our Sun is getting a bit frisky these days, and has rewarded us with perhaps the best screensaver image ever taken. The incredibly detailed photo of a sunspot was actually taken back in January by the Daniel K. Inouye Solar Telescope, a 4-meter instrument with adaptive optics that can image the sun from the near-infrared […]
