A clever DIY modder known as High Tech Low Life has taken the idea of a cyberdeck in a refreshingly different direction: instead of building a standalone mini PC, he turned a regular smartphone into a full-blown, laptop-like cyberdeck packed with practical upgrades. Shared with the simple caption, “This took a while to build, but it has a lot of features,” the project quickly stood out for blending portability, big sound, and serious day-to-day usability into one compact clamshell build.
At its core, the cyberdeck is a custom smartphone case that unfolds like a small laptop and can open all the way to 180 degrees. But the real magic is what’s built around the phone. For audio, the setup includes a Bluetooth amp wired to two 5W stereo speakers, delivering a dramatic boost over typical smartphone speakers. For control, there’s a mini tactical keyboard paired with a touchpad, making it far easier to type, navigate, and do real work (or gaming) than tapping on glass. Powering it all is a hefty 10,000 mAh power bank designed to keep the whole rig running through long movie sessions, travel days, or extended playtime.
The build is also packed with quality-of-life features that make it feel like a thoughtfully designed mobile workstation rather than a one-off gimmick. An integrated USB-C hub adds extra ports for accessories, while magnetic phone attachments make it quick to swap devices. Flip-out feet help stabilize the cyberdeck on uneven surfaces, and a side handle makes it easier to carry around—an important touch for any portable cyberdeck setup meant to leave the desk.
Aesthetically and conceptually, the inspiration comes from the Atari Portfolio, the iconic late-1980s mini-computer that gained pop-culture fame thanks to its appearance in Terminator 2. In his video walkthrough, the creator explained he wanted to merge multiple devices into one: a computer, a keyboard, a boombox, a hub, and a battery—then make it small enough to actually carry.
This wasn’t a quick weekend project. He started from scratch, modeling the phone mount in Fusion 360 and carefully planning how everything would fit without making the device awkward to use. To get the clamshell action right, he salvaged hinges from an old ThinkPad, then built speaker enclosures so the audio hardware could sit securely while still keeping the whole design compact.
Even with the impressive result, the modder considers it a work in progress. Next on the upgrade list: moving from dual 5W speakers to 20W speakers and refining the keyboard layout for an even better typing experience. For anyone into cyberdecks, smartphone mods, portable computing, or DIY tech builds, it’s a standout example of how far a “simple” phone can go when it’s treated as the brain of a purpose-built mobile rig.
