Sliding-Screen Cyberdeck Has Chunky, Rugged Design

May 21, 2026 by Zoe Skyforest 26 Comments

[Jankbu] needed a new computer, but had little interest in purchasing a modern laptop off the shelf. Instead, it was time to build a cyberdeck with a neat modular design to suit his exact needs.

The heart of the build is a Raspberry Pi 5, which provides a good amount of computing power for regular tasks. It’s wrapped up in a 3D-printed enclosure with rail mounts on the back, along with a NOS 450 TKL mechanical keyboard, offering full-travel keys in a compact layout. The 10.1″ IPS touchscreen display is mounted on sliding rails to cover the keyboard when it’s not needed. A smattering of buttons live around the screen, in a manner akin to so many industrial controllers. On either side, the deck has large grab handles, with one side featuring custom horizontal and vertical scroll controls, while the other rocks a trackball. Power is via NP-F batteries, which are more commonly used to run Sony camcorders.

Unlike so many cyberdecks, [Jankbu] didn’t just build the device to look cool—it also serves a practical purpose. It’s great for running Freecad, and the rail mounts on the rear make it perfect for mounting around the workshop during a job as needed. Files are on Github for those eager to learn more.

What’s fun about this build is that it’s not just a show piece, it’s something that gets used every day. That’s a testament to [Jankbu’s] well-reasoned design, that considered what the device was for before it was put together. We’ve featured plenty of other fantastic cyberdecks in the past, too.

A Trackball 3D Controller

April 27, 2026 by Jenny List 33 Comments

We use CAD packages in our 3D work, and it’s likely that many of us have become annoyed by the limitations of controlling the view of a 3D object using a 2D interface, our mouse. Joystick-like 3D controllers exist for this purpose, but [David Liu] found them inconvenient. He tried a trackball, but that didn’t improve matters. His response was to take the trackball and change the way it controlled the software, turning it from the equivalent of a ball rolling over a surface to a ball representing the object on the screen itself. He can turn and rotate the object intuitively just by moving the ball.

He started with a Kensington off-the-shelf trackball and adapted its electronics and handy twin optical sensors such that it worked in the required fashion. There was a lot of iterating and tuning to get the control feeling right, but he’s ended up with a peripheral that replaces both mouse and 3D joystick, and leaves the other hand free for those keyboard shortcuts.

Keebin’ With Kristina: The One With The Cheesy Keyboard

Let’s just kick things off in style with the fabulously brutalist Bayleaf wireless split from [StunningBreadfruit30], shall we? Be sure to check out the wonderful build log/information site as well for the full details.

Image by [StunningBreadfruit30] via reddit

Here’s the gist: this sexy split grid of beautiful multi-jet fusion (MJF) keycaps sits on top of Kailh PG1316S switches. The CNC-machined aluminium enclosure hides nice!nano boards with a sweet little dip in each one that really pull the keyboard together.

For the first serious custom build, [StunningBreadfruit30] wanted a polished look and finish, and to that I say wow, yes; good job, and nod enthusiastically as I’m sure you are. Believe it or not, [StunningBreadfruit30] came into this with no CAD skills at all. But it was an amazing learning experience overall, and an even better version is in the works.

I didn’t read the things. Is it open-source? It’s not, at least not at this time. But before you get too-too excited, remember that it cost $400 to build, and that doesn’t even count shipping or the tools that this project necessitated purchasing. However, [StunningBreadfruit30] says that it may be for sale in the future, although the design will have an improved sound profile and ergonomics. There’s actually a laundry list of ideas for the next iteration. Continue reading “Keebin’ With Kristina: The One With The Cheesy Keyboard” →

Keebin’ With Kristina: The One With The Typo

November 18, 2024 by Kristina Panos 15 Comments

Ceci n’est pas une keyboard, sure. But it’s keyboard-adjacent, and how. [Joshua Bemenderfer]’s wrists are tired of moving off the keyboard in order to mouse, and he decided to create a trackball that can sit just below the Space bar. The idea is to get rid of the regular mouse entirely if this works out.

And sure, the Ploopy family of open-source mice would welcome him with open arms, but they don’t come cheap. [Joshua]’s plan here is to make something for under $10. Ideally, less than $5.

Starting with an off-the-shelf trackball, the first BOM came in around $25 if you throw in $5 for the 3D printing of the case. [Joshua] added some cheap ceramic bearings to make it better. Since this was still too high, he turned to the internals of cheap mice.

Trial and error has resulted in a 99-cent special from Ali being the idea candidate. There are even cheaper mice to be had, but this one has an ideal layout for doing a bit of surgery. It also requires remapping since [Joshua] is flipping the sensor upside down and using a POM ball on top of it. Now he just needs to figure out how to add buttons and make them split keyboard-friendly.

This OSHW Trackball Is Ready To Be Customized

November 1, 2023 by Tom Nardi 25 Comments

Oh sure, Amazon can deliver any number of Logitech peripherals to your door in 48 hours, but where’s the fun in that? With open source hardware (OSHW) input devices like the Ploopy Adept Trackball, you not only get to say you built the thing yourself, but there’s also an opportunity to tune the gadget to your exacting specifications — even if that just means packing it full of RGB LEDs.

The trackball is powered by the Raspberry Pi Pico running QMK, features a high-accuracy PMW3360 sensor that can be found in commercial gaming mice, and uses a snooker ball for the business end. All the hardware is wrapped up in a 3D printed enclosure, and thanks to the VIA project, configuring the device can be done right in the browser through a web app.

Like the other devices in the (somewhat unfortunately named) Ploopy family, all of the design files for the Adept Trackball are released under the CERN license, which combined with the project’s fantastic documentation means you’ve got everything you need to build it from scratch. There are official parts kits if you don’t want to source or print all the components yourself, but as of this writing, the Ploopy Shop will only let you preorder them.

2023 Cyberdeck Challenge: Crosberry Pi Loves Lo-Fi Hip Hop

July 22, 2023 by Kristina Panos 1 Comment

As far as we can tell, the only real selling point that any portable record player offered was, well, its portability. To be clear, the sound is never that great. But perhaps a selling point for this crowd is that they usually come in hinged cases with handles, and you know what that means — cyberdeck that thing!

[Mx. Jack Nelson] started gutting this Crosley CR40 record player to make a Raspberry Pi housing, but it quickly turned into a cyberdeck project with the addition of a 10.1″ portable monitor, a Planck ortholinear keyboard, and a gutted trackball mouse.

We love that [Mx. Jack Nelson] made use of the Crosley’s original speakers — this was the wife’s idea! — as well as the volume and tone knobs. But our favorite part has to be the clear acrylic top that both protects the electronics and provides a platform for the keyboard and mouse buttons. Be sure to check out the demo video after the break.

A Miniature MNT For Every Pocket

April 11, 2023 by Kerry Scharfglass 35 Comments

Last time Hackaday went hands on with a product from German company MNT, it was the Reform laptop; a full size computer with a full feature set and fully open source design. Now they’re back with the same value proposition and feature set crammed into a much more adorable (and colorful!) package with the MNT Pocket Reform. If you want the big Reform’s open source philosophy in a body fit for a coat pocket, this might be the computing device for you.

To refresh your memory, MNT is a company that specializes in open source hardware and the software to support it. They are probably best known for the Reform, their first laptop. Its marquis feature is a fully open design, from the mechanical components (designed with OSS tools) to the PCBAs (designed with KiCad) to the software (designed with, uh, software). When originally shipped that product packed a DIMM-style System On Module (SOM) with a default configuration containing a quad core NXP i.MX8M Quad and 4GB of RAM, as well as mini PCIe Card and M key m.2 2280 slots on the motherboard for storage and connectivity. That computer was designed to be easily serviceable and included a plethora of full sized ports along with easy to source cylindrical battery cells. The Pocket Reform takes the same intent and channels it into a much smaller package.
