This $119 Ultrasonic Cutter Sense Materials And Auto-Adjusts To Cut EVA Foam, Resin, PLA 3D Prints

Posted on by

There are power tools, and then there are smart tools. A power tool gives you brute force; a smart tool gives you controlled, consistent results. Think of a simple drill that just spins versus one that manages its own torque to avoid stripping a screw. For delicate work like trimming EVA foam for a cosplay project or cleaning up support structures on a 3D print, you definitely want the smart one. The problem is, most handheld cutters are pretty basic, giving you one speed and just hoping for the best.

The SonicMax Slice 10 is aiming for that higher IQ. It’s a cordless ultrasonic cutter that senses the material you’re cutting and adjusts its own power output in real time. Slice through dense plastic and it pushes harder; trim the thin walls of a resin print and it eases back. This adaptive system, combined with cooling that prevents heat-related power drops, makes it feel like proper workshop equipment in the palm of your hand. It runs at 40kHz, delivers up to 50 watts of dynamic peak power, and does all of this without a single cable getting in your way.

Most ultrasonic cutters on the market use transducers with a mechanical quality factor, or Qm, somewhere between 150 and 250. A higher Qm means the transducer converts electrical energy into vibration more efficiently, which directly translates to less heat generated during use. SonicMax claims a Qm of over 500 for the Slice 10, and lab data backs that up with a verified measurement of 541.1. That’s roughly two to three times higher than a typical competing tool, and it’s the foundational reason the Slice 10 can sustain longer sessions without thermal drama. That single transducer decision cascades into everything else, from runtime and cut quality to how comfortable the tool actually stays in your hand.

As the blade meets resistance, the Slice 10’s Smart Material Auto-Detection reads that feedback and adjusts power output and vibration frequency without you touching anything. Cutting through a stiff chunk of EVA foam feels different from trimming the thin walls of a resin print, and the tool responds to each material accordingly. You’re not locked into a fixed setting that works okay for most things but perfectly for nothing. The system also preserves cut quality across a long session, where material resistance can shift as the blade warms. The result is consistent cuts from the first pass to the last, regardless of what you’re running the blade through.

Heat is the reason most cordless ultrasonic cutters force you to stop every five to ten minutes, and the Slice 10 attacks that problem from two directions. Corded bench tools sidestep this issue by drawing steady power and dissipating heat more easily, but you give all of that up the moment you cut the cord. The high-efficiency transducer generates less heat from the start, and the built-in active cooling fan manages whatever thermal load does build up during a session. Overheat protection kicks in automatically at 80 degrees Celsius at the motherboard level, so the tool protects itself without you having to babysit it. You only appreciate how good this is after you’ve spent a session on a cutter that kept shutting itself off on you mid-cut.

A 5000mAh 21700 lithium-ion battery powers the Slice 10, and SonicMax made it user-replaceable, which you’ll end up appreciating far more than any spec sheet number. The 21700 is a high-performance cell format found in premium flashlights and power tools, so sourcing replacements from SonicMax or compatible third-party brands should never be a problem. SonicMax’s own branded replacement cell is rated for 500 charge cycles at 80% capacity retention, a reasonable lifespan for a tool you’re actually putting to work regularly. An 18W USB-C pass-through charging system brings it from zero to full in about 70 minutes, and the tool keeps running while plugged in. Claimed runtime sits at up to four hours, and when you run low mid-project, swapping in a spare takes seconds.

Blade choice gives the Slice 10 a lot of its bench-tool personality. SonicMax offers five blade styles that let the same handheld body take on very different jobs: a Standard Utility Blade for everyday trimming, a Precision Long Blade for tighter access and more delicate reach, a Fine Chisel Blade for careful cleanup work, a Heavy Duty Chisel Blade for more aggressive material removal, and a Wide Flat Scraper Blade for broader surface work. That range matters because it turns the Slice 10 into something closer to a compact cutting system than a one-trick knife. If you’re the kind of maker who bounces between foam, plastic, supports, edges, and surface cleanup in the same afternoon, this is where the tool starts looking properly versatile.

Lift-to-Activate sensing turns the tool on when you pick it up and off when you set it down, keeping your fingers away from controls mid-session and preventing accidental activation on the bench. A small OLED display shows real-time power output and battery level, so you’re never left guessing how much runtime remains. Built-in LED lighting illuminates the cut line, which sounds like a minor detail until you’re trying to trace a clean edge on a dark-colored print at your desk at some ungodly hour. Auto-shutdown kicks in after five minutes of idle, and low-battery protection activates before the cell drops to a damaging voltage. Together, these details make the Slice 10 feel like a tool that respects your workflow rather than constantly asking you to manage it.

The Slice 10 measures 260.5mm long and 28mm across, weighing 236 grams, keeping it firmly in single-hand, pen-grip territory across long sessions. Just the Slice 10 is available for a discounted $119, and ships with 10 replaceable Standard Utility blades. Upgrade to the Maker’s Bundle for $169 and you get the Slice 10 along with 50 blades spread across the five blade profiles (standard, precision long, fine chisel, heavy duty chisel, and flat scraper) as well as a 5000mAh replacement battery. If you’re looking for versatility and pushing your prints to the max, the $50 price bump does bring a fair share of value. You can also buy extra blades and batteries as add-ons. Shipping is expected to begin mid-October 2026 with worldwide delivery available, and SonicMax has not publicly confirmed warranty terms at the time of writing.

Unofficial Audi A8 Concept Keeps Classic Sedan Proportions and a Traditional Grille

Posted on by

The Audi A8 died in early 2026, quietly, the way flagships die now. Order books shut in Germany, production wound down, and the Q9 SUV inherited the crown after the A8 managed 1,406 US sales in a year the Q8 did 10,881. Audi swears a fifth generation arrives around 2030. Luca Serafini apparently decided four years is a long time to sit around, so he built one himself. His version borrows the Concept C’s monolithic surfacing and four-element light signature, then quietly refuses the vertical Singleframe, running a full-width horizontal bar with the four rings lit at center instead, plus twin exhausts in the diffuser.

Everything else on the car is doing less on purpose. Six-spoke wheels with cross-drilled discs behind them, blacked-out pillars, flush glass, a shoulder line so soft you have to hunt for it, and a titanium-silver finish borrowed straight from Concept C’s anodized aluminum look. Those illuminated rings front and rear go dark the second any regulator sees them, and the front overhang is shorter than crash structure would ever allow. Neither problem makes the renders less convincing. They just mark exactly where a designer stopped negotiating with reality.

Designer: Luca Serafini, LS Design

The vertical Singleframe remains the most argued-about thing Audi has done in a decade, and Serafini declines it outright. Massimo Frascella built that upright slab for the Concept C by reaching back to the 1936 Auto Union Type C and the 2004 A6, and when we spent forty minutes with the car in Munich it absolutely worked at roadster scale. Stretch the same face across five-plus meters of limousine, though, and authority starts sliding toward novelty toothpaste tube. What replaces it is a wide horizontal aperture with the rings glowing dead center, flanked by the four-element light graphic Audi now uses front and rear. Autoevolution called the result tame. I’d call it a designer knowing what a big car’s face has to do.

Audi built the slipperiest sedan on the planet in 1982 by bonding the side glass flush with the bodywork, hitting a drag coefficient of 0.30 and calling itself the aerodynamics world champion. Forty-four years later the same instinct gets rebranded as radical simplicity. Serafini’s A8 runs the C3 playbook almost literally, with flush glazing, no visible door handles, blacked-out pillars, and a body carrying zero character lines. The whole surface works on volume and reflection alone, which is the hardest thing to pull off in car design and the easiest to botch. Broad rear haunches and a near-vertical Kamm tail keep it from reading as a bar of soap.

Twin oval outlets sit in the black rear diffuser, which rules out any A8 e-tron reading immediately. That looks prophetic rather than backward-facing, given Audi scrapped its 2033 combustion cutoff and then dropped the 987-hp Nuvolari, a 4.0-liter twin-turbo V8 with three axial-flux motors and a 10,000 rpm redline, in the exact year it once promised to go electric-only. A green vertical accent in the lower intake muddles the story slightly, since it reads like a charge-status indicator on a car with tailpipes. Serafini has been running Concept C surfacing across an imaginary Audi lineup since last September, covering an SUV, a hot hatch, an A2 revival and an R8 Spyder. This flagship is his second run at the A8.

Frascella’s rule now is that Audi shows nothing it cannot build, which makes independent work like this the only place ambition still runs unsupervised. Serafini works in Blender, 3DS Max and Unreal with AI in the pipeline, so the images are staged rather than surfaced from production CAD, and a few details fall apart under close reading. His Ferrari single seater from yesterday had the same quality, gorgeous and structurally impossible in roughly equal measure. What this A8 proves is that the segment’s problem was never the shape. Audi walked away from the sedan because buyers did, and a car this composed makes that math feel like a shame.

This CD Player Doesn’t Hide Its Mechanism, It Puts It on Display

Posted on by

If you think compact discs are a thing of the past, you probably haven’t been around a K-pop fan or a hoarder who still has their CDs from decades ago. Then there are people like me who have a stack of CDs collected over the years but no actual CD player to enjoy them on, since options that are strong on both quality and design are hard to come by.

The ClearFrame Speaker CD Player is a solid choice for anyone looking for a visually stunning player that won’t let a CD’s album art go to waste. It lets you slot the jacket art onto the front of the player so it becomes a rotating piece of wall or shelf art. Or, if you’d rather show off the mechanics, you can leave the artwork out and display the transparent body itself, watching your CD spin with all its moving (and non-moving) parts in full view.

Whenever I come across beautiful album art, I can’t help but think it’s wasted if it only ever gets seen as a tiny digital thumbnail on a streaming app. A player like the ClearFrame Speaker CD Player lets you put that kind of artwork on full display while you’re enjoying the music in your room. Seeing something that the artist, and the album art designer, worked hard on come to life while it spins gives it the justice it deserves. And if you’d rather see the clear, polycarbonate-style body become a piece of art in its own right, just take out the album cover and let it shine in all its transparent glory.

This is also an upgraded version of the original, and already popular, ClearFrame CD Player, since it now comes with a built-in speaker. That means you no longer need to hook it up to an external Bluetooth speaker or wired setup, which makes it even more flexible to display anywhere in your home. You actually have three ways to listen to your favorite CDs: through the built-in 40mm speaker, with wired headphones through the 3.5mm jack, or over Bluetooth 5.3 to external speakers or headphones if you already have a better setup you’d like to use.

Beyond the listening options, the ClearFrame Speaker CD Player was clearly designed with portability in mind. At just 454 grams (about a pound) and roughly the size of a hardcover book, it’s light enough to carry from your bedroom to your living room without a second thought. Its 1,800mAh battery gives you around six to seven hours of playback through the built-in speaker, or seven to eight hours if you’re streaming over Bluetooth, so you can enjoy a few albums back-to-back before needing to recharge via USB-C. There’s even a retro-style LED Nixie tube display that adds a warm, nostalgic touch to the whole experience, plus a 2MB SDRAM anti-shock buffer so accidental bumps won’t make your music skip.

For collectors, this player also solves a real problem: what to do with all the CDs sitting untouched in a drawer somewhere. Instead of treating them like outdated clutter, the ClearFrame gives them a reason to come back out, whether that’s a K-pop photocard-era album, a mix your best friend burned for you in high school, or a boxed set you’ve been meaning to revisit. It turns “old technology” into a genuine decor piece you’d be proud to leave out on a shelf.

If you’re looking to gift this to someone (or, let’s be honest, treat yourself), the ClearFrame Speaker CD Player comes in a few configurations depending on how you plan to display it. You can pick it up on its own, or add a wall mount, book case, or display stand, so it fits neatly into whatever corner of your home you have in mind. It isn’t the cheapest CD player on the market, but if you have a stack of CDs with nowhere to go and album art too good to keep hidden, this one earns its price tag by turning something you already own into something worth looking at every single day.
