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 […]

RGB LED Rings Teach Old Dash New Tricks

We’ve seen several so-called “digital dash” upgrades over the years that either augment, or completely replace, a vehicle’s original dashboard indicators with new displays. Whether its seven segment LEDs or a full-on graphical interface powered by the Raspberry Pi, the end result is the same: a dashboard that looks wildly different than it did when […]

The Beat Goes On With This ESP32 Page Turner

Looking for a hands-free way to page through sheet music on an iPad, [The_Larch] came up with this simple Bluetooth input device based on the ESP32. The microcontroller just needed to have two switches wired into the GPIO pins, in this case the same heavy-duty plungers you’d find on a guitar pedal, and a USB […]

Bluetooth PS3 Controllers Modernize The Nintendo GameCube

While the PlayStation 3 and Gamecube come from opposing sides of the aisle, and in fact aren’t even from the same generation of hardware, this DIY adapter built by [Jeannot] allows Nintendo’s console to use Sony’s Bluetooth controllers with surprisingly little fuss. This might seem unnecessary given the fact that Nintendo put out an official […]

Putting The Magic Smoke Back In A Cooked Scooter

When [Vitor Melon] found out there was a custom firmware (CFW) available for his Xiaomi Mijia M365 Pro electric scooter that would increase his top end speed, naturally he installed it. Who wouldn’t want a little more performance out their hardware? But while the new firmware got the scooter running even better than stock, he […]

Apple II Talks To 3D Printer With A Little Modern Help

Controlling most desktop 3D printers is as easy as sending them G-code commands over a serial connection. As you might expect, it takes a relatively quick machine to fire off the commands fast enough for a good-quality print. But what if you weren’t so picky? If speed isn’t a concern, what’s the practical limit on […]

This Stackable Pi Portable Is Ready To Rumble

The proliferation of desktop 3D printing and powerful single-board computers like the Raspberry Pi has given rise to an absolute explosion of small bespoke computing devices. Whether or not you think these cobbled together devices are close enough to Gibson’s original vision to call them cyberdecks, it’s a remarkable shift from the norm that brings […]

GBA Gets Homebrew USB-C Charging Upgrade

Sure there are pre-made kits to add a rechargeable battery and USB-C compatibility to Nintendo’s venerable Game Boy Advance, but [HorstBaerbel] thought he could throw together something similar for a fraction of the price. Plus, he wouldn’t have to wait on shipping. The end result might not be quite as polished, but it’s certainly impressive […]

LoRa Messenger Does Its Best BlackBerry Impression

While the de facto smartphone design ultimately went in a different direction, there’s no denying the classic BlackBerry layout offered some compelling advantages. It was a gadget primarily designed to send and receive emails and text messages, and it showed. So is it really any wonder [MSG] would build his pocket-sized LoRa messengers in its […]
