After Losing His Arm in a Crash, He Built the Controller No One Made

Gaming peripherals have come a long way in terms of specialization, from mechanical keyboards tuned for competitive play to mice with adjustable DPI profiles and ergonomic grips. What hasn’t kept pace is hardware designed for players who can only use one hand. Existing options like gaming keypads only get so far, and none of them truly replace the keyboard and mouse combination that PC gaming has relied on for decades.

Joe Tomasulo found that out the hard way. After losing his right arm in a motorcycle accident, he’d tried everything to get back to PC gaming as he knew it. He adapted a Razer Tartarus, strapped a wireless mouse to it, and tweaked the software bindings endlessly, but nothing ever felt right. Rather than keep settling for workarounds, he eventually built something purpose-made, and the result is the Ercham MK1.

Designer: Joe Tomasulo (Adventurous_Tie_9031)

The core idea is to put the keyboard and the mouse into the same device so that one hand handles everything at once. The Ercham MK1 sits flat on a surface, and an optical sensor on its underside lets the entire unit glide like a conventional mouse. The hand resting on top can simultaneously press keys, scroll, and execute game commands without ever having to reach for a second peripheral.

The key section features more than 30 programmable inputs arranged in a compact grid within natural finger reach. A strap system runs across the top of the device, keeping the hand firmly in place during longer sessions without requiring a tight grip. That matters for players with limited hand strength or residual limb use, where maintaining position on a mouse-like surface for extended periods would otherwise be exhausting and imprecise.

One of the more considered design decisions is that the Ercham MK1 works for either hand. Most gaming keypads aren’t built for both; they default almost universally to left-hand use, leaving right-handed amputees and players with right-side impairments without a natural fit. The fully ambidextrous layout, combined with angled control modules on both sides of the device, means the setup adapts to the user rather than the other way around.

Joe built the Ercham MK1 with amputees and stroke survivors specifically in mind, but its potential reach extends well beyond those two groups. Players dealing with RSI, brachial plexus injuries, and chronic pain face the same frustrations with two-device setups that don’t accommodate them, and so do power users and content creators. The programmable layout and macro support make it a genuinely useful tool for productivity work, not just gaming.

It’s come a long way from the hacked-together prototype he started with, and that origin gives it a kind of credibility that polished gaming accessories rarely have. It wasn’t designed in a studio; it was built by someone who genuinely needed it and couldn’t wait for anyone else to.

Casio Just Built a $270 Sampler the SK-1 Always Deserved

When Casio showed up at NAMM in January with an unannounced sampler, no press rollout, no teaser campaign, people kind of lost their minds a little. It was unexpected in the best way. The music gear community had not been thinking about Casio in that particular conversation, and then suddenly there it was. A boxy, padded, retro-looking device called the SXC-1, sitting quietly in a booth like it had always been there. That kind of entrance says a lot about how confident Casio was in what they brought. It also signals something bigger: Casio is not just trying to stay relevant. They are actively reclaiming territory they actually originated.

For a certain kind of person, whether you are a producer, a music nerd, or a design obsessive, the Casio SK-1 is practically sacred. Released in 1985 for about $100, it was a small plastic sampling keyboard that let you record any sound and play it back across a tiny row of keys. It was deliberately toy-like, and yet it ended up in the hands of experimental musicians, lo-fi producers, and everyone in between. The SK-1 was the gateway into sampling for an entire generation, and its cultural weight has never really gone away.

Designer: Casio

The SXC-1 is Casio’s answer to where that legacy goes next. The aesthetic DNA is still present: the boxy form factor, the emphasis on immediate usability, the sense that this is a tool meant to be picked up and played without a manual. But where the SK-1 was charming in its limitations, the SXC-1 is built for serious work. The specs back that up. It runs on a 16-bit/48kHz sampling engine with 64GB of onboard eMMC storage, supports WAV, MP3, and FLAC files, and gives you up to 15 minutes of total sampling time. A 1.3-inch OLED screen and two large rotary encoders handle the interface, and the 4×4 pad layout gives you 16 pressure-sensitive pads tuned specifically for finger drumming.

It also ships with over 80 sample banks pulled from classic Casio instruments, including the SK-1, SK-5, CZ-101, and MT-40. Those loops are automatically tempo-synced via a beat-sync function, which is a genuinely smart move. It means that even out of the box, with zero setup, you have a ready library of usable, nostalgia-soaked sounds that are immediately production-ready. For content creators or producers who need to move fast, that matters more than most brands realize.

The connectivity is equally well-considered. There is a built-in mic, external analog input, USB audio, headphone output, main output, and dual USB-C ports for data and power. This is clearly built for people who move between environments: bedroom studios, live sets, cafes, wherever the work happens to be. Battery life sits at around two hours, there is a built-in speaker, and the device ships with step sequencing at up to 50 patterns of 8 bars each. Effects are on the leaner side, covering filter, flanger, phaser, and bitcrusher, but that restraint feels intentional rather than cheap.

Casio is marketing the SXC-1 explicitly as a tool for the “Creator Economy,” which is the kind of phrase that usually makes me skeptical. But here it actually fits. Independent artists and producers today are working across formats, platforms, and workflows all at once. They need gear that is fast, flexible, and small enough to live in a backpack. The SXC-1 appears to understand that assignment.

The device is currently available for pre-order on the Casio Japan website at 39,930 yen, with a release date of May 28, 2026. Global pricing has not been confirmed, but estimates put it somewhere between $230 and $300 depending on region.

Whether the SXC-1 lands the way Casio hopes will depend partly on how it feels in hand, which is something specs cannot fully answer. But the design intent is clear and it is smart. Casio looked at what made the SK-1 culturally significant, stripped out the nostalgia bait, and built something that can actually do the job today. That is not a small thing.

Lofree Hyzen: A High-End Custom Mechanical-Magnetic Keyboard for Every Scenario

The keyboard market often feels split into two very different camps. Mechanical boards have long been the preferred choice for people who care about typing feel, delivering consistent keystrokes and a tactile quality that makes long sessions more enjoyable. Magnetic keyboards, meanwhile, have become the go-to for gamers needing precise, adjustable input and rapid trigger performance. Both are capable, but each comes with its own trade-offs.

That split is exactly what Lofree is trying to bridge with the Hyzen, a compact 67-key keyboard that approaches the category with a slightly different proposition. Working with Kailh, Lofree developed the Nexus switch, combining a mechanical structure with magnetic sensing in a single unit. The idea, of course, is that you shouldn’t have to choose between how a keyboard feels and how quickly it responds.

Designer: Matt (Lofree)

Beyond the technology inside, the Hyzen is clearly built to belong on a thoughtfully put-together desk. The CNC-machined aluminum body, clean geometry, and balanced proportions give it a composed presence that doesn’t lean into the visual language typical of gaming hardware. Available in Space Gray and Silver, it carries far more of the character of a premium desk accessory than a performance peripheral.

The lighting follows the same restrained approach. Rather than making RGB the main event, Hyzen uses subtle front ambient lighting and a light strip along its front edge that adds atmosphere without taking over. High-transparency PC keycaps with a matte UV coating and front-printed legends keep the visual detail quiet. It’s the kind of setup that works best in calmer, low-light arrangements where you want mood without the theatrics.

The Nexus switch is where the Hyzen’s concept actually becomes tangible. A single shortcut toggles between mechanical mode, which uses traditional contact-based actuation, and magnetic mode, which unlocks the performance features. According to Lofree, the physical typing feel stays consistent across both. What changes is how the input gets detected, which is Lofree’s answer to a problem many users know well.

On the productivity side, Hyzen carries a 10,000 mAh battery for solid wireless runtime, whether you’re writing documents or hopping between devices. Connectivity covers wired USB, 2.4 GHz, and Bluetooth, so switching between a work machine and a personal setup doesn’t take much effort. The PCB gasket construction and FR4 fiberglass plate also contribute to a more considered typing feel that holds up well over longer sessions.

Switch to gaming, though, and things get considerably more interesting. Magnetic mode unlocks adjustable actuation with 0.01 mm precision, rapid trigger with 0.01 mm accuracy, and a dual 8K polling rate at 8,000 Hz on both keyboard and receiver. Wired latency sits at 0.36 ms, with 2.4 GHz at 0.65 ms. Those are numbers competitive setups look for, in hardware that, for once, doesn’t look aggressive doing it.

There’s also a multi-function key window that lets you toggle between the F-row and number row, with a visual indicator showing the active mode at a glance. It’s a small detail, but a genuinely useful one on a compact layout where function layers can get confusing fast. Hot-swap support, macro functionality, and web-based key mapping round out a package that covers more ground than you might expect.

Keyboards that try to balance aesthetics and performance this explicitly still feel relatively uncommon. Most still ask you to pick a lane, whether that means living with something that looks aggressive on a clean desk or one that feels clinical when you’d prefer more character. Hyzen is trying to sit in between, which is either the smartest place to be or the most difficult one, depending on who you ask.
