The smart home speaker market has settled into a familiar aesthetic. Smooth cylinders, matte finishes, and understated designs meant to disappear into a room are the default for most voice assistants. It’s a reasonable approach, but it also means most of them look exactly the same, and the hardware driving them tends to get replaced every couple of years, whether it actually needs to be or not.
HANDMAX Workshop took a different approach entirely. Rather than buying new hardware, the build starts with a Xiaomi Mi 8 already well past its prime, complete with a burned-in display, degraded speakers, and a failing battery. The processor and software capabilities were still perfectly usable, though, and that turned out to be all this kind of project actually needs.
Designer: HANDMAX Workshop
The case is where things get interesting. Instead of a sleek enclosure meant to blend in, the HANDMAX design goes full retro television, with a front grille, physical control buttons, and decorative legs completing the picture. Carefully modeled 3D-printed parts handle the practical side of things, accommodating the phone’s sensors and camera while keeping the vintage illusion intact from every angle you look at it.
Put it on a desk, and you have a smart speaker that looks like something rescued from a garage sale, in the best possible way. Ask it a question, and Google Gemini handles the conversational side, pulling in responses without needing a dedicated microprocessor or a new development board. It’s the same AI model powering higher-end commercial devices, running on hardware that would otherwise be sitting in a drawer.
The smart home integration is what makes it genuinely useful beyond being a conversation piece. Through Google Home, the device can control smart home accessories directly, and custom routines let voice commands trigger specific actions around the house. Turning lights on, adjusting a thermostat, or running a sequence of automations becomes a spoken instruction directed at what looks like a miniature television set.
Getting there wasn’t entirely straightforward. The phone’s Bluetooth module had a habit of shutting itself down after 20 minutes of silence, which would quietly cripple the whole setup. The fix was characteristically clever, though; an inaudible 6 Hz tone runs constantly in the background, imperceptible to human ears but enough to convince the firmware that the system is still in use and shouldn’t shut down.
Beyond voice interaction, the finished device also functions as a wireless charger and a desktop display, which means it earns its counter space even when no one is talking to it. The final hardware list doesn’t include a single new component, just old parts that most people would have discarded without a second thought. That’s the more interesting design challenge of the two.
There’s an argument to be made that the best AI hardware isn’t always the most expensive, and this project makes it quietly. Commercial smart speakers are bought, used for a few years, and eventually replaced. A device built from broken hardware doesn’t follow that lifecycle, and the retro TV case that holds it together makes sure it doesn’t look like it’s trying to.
