The TrimUI Brick Hammer: A Tiny Retro Handheld That Does a Lot More Than Play Games
I recently picked up a retro handheld gaming device called the Brick Hammer, made by a company called TrimUI. I'd been seeing more and more chatter online about the growing popularity of these pocket-sized emulation handhelds, and after a little research, I decided to see what all the fuss was about. A few days in, I'm genuinely impressed, not just by what it does for gaming, but by how much more it turns out to be capable of.
What Is the Brick Hammer?
TrimUI isn't a household name the way Anbernic or Retroid are, but the Brick Hammer makes a strong case for the company deserving more attention. It's the premium variant of TrimUI's original Brick, built around a CNC-machined aluminum alloy shell instead of plastic gives it a surprisingly solid, dense feel in the hand, more like a piece of precision hardware than a toy. The 3.2-inch full-lamination IPS display is sharp and vivid for its size, and the metal body also acts as a heat sink, helping the device stay cool during longer sessions.
Under the hood, it runs on Linux, which is the real key to everything else this device can do. Rather than shipping with a closed, locked-down OS, TrimUI leans into the retro handheld community's long tradition of building open, swappable firmware on top of the base hardware.
Emulation, Covered
Out of the box, the Brick Hammer emulates the usual suspects (NES, SNES, Sega Genesis, the Game Boy family) but its hardware has enough headroom to comfortably handle the original PlayStation as well, with partial support for chunkier systems like the N64, PSP, and even Dreamcast. It's not going to replace a dedicated N64 or Dreamcast machine, but as a bonus on top of near-flawless PS1 and 16-bit emulation, it's a nice bit of extra headroom to tinker with.
A Thriving Custom Firmware Scene
Because the device runs Linux, a community of developers has built a whole ecosystem of custom firmware (CFW) options you can flash onto an SD card, no soldering or hacking required. I'm currently running NextUI, one of the more popular choices, which replaces the stock menu with a clean, minimalist interface built on top of the RetroArch emulation core. It automatically scrapes box art and metadata for your game library, so instead of a folder of ROM filenames, you end up with something that looks and feels like a curated digital shelf. Other options in the same family (MinUI, muOS, SpruceOS) take slightly different approaches to the same idea: a fast, no-frills launcher that gets out of the way of actually playing games.
More Than a Game Console: A Pocket Music Player
Here's the part that surprised me most. Beyond gaming, the Brick Hammer moonlights as a genuinely capable digital music player. There's something delightful about the tactile, physical-button experience of scrolling through a music library the way we used to on the classic click-wheel iPods, a feeling that's been mostly lost in the touchscreen era.
What really caught my attention, though, was the audio quality. The analog output is surprisingly clean and detailed when playing FLAC files, enough that it doesn't feel like an afterthought bolted onto a gaming device. And for anyone who wants to take it further, the Brick Hammer can output to an external amp or DAC, opening the door to a genuinely more audiophile-grade listening setup. It's a rare thing to find a sub-$100 handheld that treats its audio output as a real feature rather than a checkbox.
A Platform for Making Music, Too
The versatility doesn't stop at playback. There are community-built synthesizer and sampling apps available for the device, aimed at anyone who wants to actually create music rather than just listen to it. It's a small but telling sign of how far the homebrew scene around these handhelds has come. What started as "let's emulate old game consoles" has evolved into a broader platform for creative, low-power computing in your pocket.
Where This Is Headed
What excites me most about the Brick Hammer isn't any single feature, it's the trajectory. Between the active CFW community, the growing library of homebrew apps, and TrimUI's own momentum (they've already followed up the original Brick with the Brick Pro), it feels like this little device's usefulness is still very much a work in progress, with new capabilities showing up all the time. For $70–80, it's hard to think of another piece of hardware that punches this far above its price as a retro gaming console, a FLAC capable music player, and now, apparently, a music-making tool as well.
I'll be curious to see what developers dream up for it next.
