A Precisely Elegant Cyberdeck Handheld

[Nicholas LaBonte] shows off a Cyberdeck Handheld that demonstrates just how good something can look when care and attention goes into the design and fabrication. He wanted to make something that blended cyberpunk and nautical aesthetics with a compact and elegant design, and we think he absolutely succeeded.

On the inside is a Raspberry Pi and an RTL-SDR. The back of the unit is machined from hardwood, and sports a bronze heat sink for the Raspberry Pi. The front has a prominent red PSP joystick for mouse input and a custom keyboard. The keyboard is especially interesting. On the inside it’s a custom PCB with tactile switches and a ATmega32U4 running QMK firmware — a popular choice for DIY keyboards — and presents to the host as a regular USB HID device.

The keys are on a single plate of little tabs, one for each key, that sits between the front panel and press on the tact switches inside.

How did he make those slick-looking keys? It’s actually a single plate that sits between the front panel and the switches themselves. [Nicholas] used a sheet of polymer with a faux-aluminum look to it and machined it down, leaving metal-looking keys with engraved symbols as tabs in a single panel. It looks really good, although [Nicholas] already has some ideas about improving it.

On the right side is the power button and charging port, and astute readers may spot that the power button is where a double-stack of USB ports would normally be on a Raspberry Pi 5. [Nicholas] removed the physical connectors, saving some space and connecting the USB ports internally to the keyboard and SDR.

As mentioned, [Nicholas] is already full of ideas for improvements. The bronze heat sink isn’t as effective as he’d like, the SDR could use some extra shielding, and the sounds the keyboard ends up making could use some work. Believe it or not, there’s still room to spare inside the unit and he’d maybe like to figure out a way to add a camera, GPS receiver, or maybe a 4G modem. We can’t wait! Get a good look for yourself in the video, embedded below.

Shelved Kindle Gets New Life As Weather Display

In the rush to always have the latest and greatest, it’s not uncommon that perfectly serviceable hardware ends up collecting dust in a drawer somewhere. If you’ve got an old Kindle laying around, you may be interested in this write-up from [Hemant] that shows a practical example of how the popular e-reader can be pushed into service as a weather dashboard.

The first step is to jailbreak the Kindle, providing the user with root access to the device. From there the Kindle Unified Application Launcher (KUAL) is installed along with USBNetwork which allows you to connect to the reader over SSH. With root access and a network connection, the real project of converting it to a weather dashboard begins. [Hemant] split the project into two parts here, a Node.js server that scrapes weather data from the internet and converts it into an image, and a client for the Kindle that receives this image for display.

The Kindle has a number of quirks and issues that [Hemant] covers as well, including handling image ghosting on the e-ink display as well as a problem where the device will hang if the Internet connection is lost. For those with jailbroken Kindles that want to put their devices back into useful service, this is an excellent guide for getting started and [Hemant] also provided all of the source code on the project’s GitHub page.

There has been a long tradition of using Kindles for things other than e-readers, and even devices with major hardware problems can still have useful life in them thanks to this project which allows the e-ink display to have a second life on its own.
