Most original NES controllers haven’t seen active duty in decades. They survive in storage bins and attic boxes, physically intact and perfectly functional as controllers, but with nothing left to plug them into. The consoles they were paired with have long since been replaced or decommissioned. The hardware was always well built, but the form factor has been sitting idle for years.

This mod changes the job description of that controller shell entirely. The electronics inside a standard NES-style gamepad were stripped out and replaced with a Wemos ESP32-S2 Mini development board, a 1.54-inch 240×240 TFT display, a MicroSD card module, a 500 mAh lithium-polymer battery, a charging board, a speaker, and a slide power switch. From the outside, it still looks exactly like an NES controller.

Choosing the right processor was essentially a geometry problem. A larger ESP32-S3 would have offered dual-core performance and enough PSRAM to keep entire game ROMs in memory, but it was too big to fit inside the housing. Smaller ESP32 variants without PSRAM lacked the memory for smooth emulation. The ESP32-S2 Mini landed in the narrow window between board size and processing capability that the build required.

Getting everything to fit required real surgery on the shell. Internal plastic supports had to be trimmed back to make room for the display, and new openings were drilled for the screen, USB charging port, MicroSD slot, speaker, and power switch. A bare copper wire serves as a central ground distribution rail, cutting the number of individual ground wires needed and making it possible to actually close the controller afterward.

On the software side, the device runs the Retro-Go emulator framework, compiled using ESP-IDF and CMake since the ESP32-S2 isn’t a standard Retro-Go target. The result handles a range of classic 8-bit systems comfortably. As a bonus, Doom runs via PrBoom-Go from a Freedoom WAD file loaded on the MicroSD card, managing somewhere between five and 15 frames per second depending on the scene.

The total build cost runs about $17 using common suppliers, or closer to $8 when sourcing directly from overseas markets. That puts the project well under the price of a single modern game release. Flip the power switch, select a ROM from the MicroSD card, and the screen loads games that once required a dedicated console and television setup. No additional hardware is needed.

What makes this more than a novelty is how it reconsiders a form factor most people already have muscle memory for. The D-pad clicks the same way it always did, and the A and B buttons carry the same spring. What changed is where the signal goes after the press. Instead of traveling to a console that no longer exists, the controller now processes it directly inside its own shell.

The Retro-Go framework is open source, the parts are widely available, and the NES controller shell is one of the most common pieces of vintage hardware still circulating through the secondhand market. Nothing about this build required specialized equipment or proprietary components. The total part list costs less than a single new game on any current platform and fits inside hardware that most people already own.

Camera batteries are one of those accessories that photographers never think about until something goes wrong. They’re small enough to vanish into the bottom of a bag or a jacket pocket, common enough to own several of and regularly mix up, and important enough that losing one mid-trip can force an early stop to a shoot. The solution most people reach for is buying more of them, which only increases the number of things to keep track of.

The FALCAM TagBatt addresses the problem from inside the battery itself. Compatible with Sony’s NP-FZ100 form factor, it integrates Apple’s Find My tracking technology directly into the cell, so the battery carries its own location data wherever it goes. If it ends up left behind at a studio, a venue, or the seat pocket of a flight, the Find My app will flag it and show its last known position.

Because the tracker lives inside the battery rather than clipped to a camera strap or screwed into a cage mount, it’s considerably harder to spot. An opportunistic thief who grabs a camera bag and removes any obvious Bluetooth puck from the outside can’t strip out what’s already built into the power source. It’s the kind of discreet integration that external trackers can’t quite replicate, no matter how small they get.

The tracking isn’t the only thing the TagBatt changes about how a camera battery behaves. A built-in USB-C port lets it charge directly from any standard USB-C source, including a power bank or a travel adapter, without needing the dedicated Sony battery charger that typically takes up its own space in a kit bag. Pop it out of the camera, plug it in overnight, and it’s ready in the morning without routing around a charger at all.

Capacity comes in at 2,600mAh against the OEM Sony NP-FZ100’s 2,280mAh, which translates to a modest but real advantage per charge. An advanced decoding chip handles the communication with the camera’s internal systems so the body treats it as it would any genuine battery, with accurate charge-level reporting and none of the “non-genuine battery” warning messages that typically accompany third-party cells.

Compatibility covers a wide sweep of Sony’s current lineup, including the Alpha 7 series through the Alpha 7 V, the Alpha 9 series, the Alpha 6700, the FX3 and FX30, and the ZV-E1, among others. A Canon LP-E6 version is also available now, with Nikon EN-EL15 and Fujifilm NP-W235 versions confirmed to be in development.

At $69.99, the TagBatt costs more than a standard third-party replacement but considerably less than the Sony original, and it comes with two capabilities that the original simply doesn’t offer. For photographers who travel frequently, work in locations where gear occasionally goes astray, or are just tired of carrying a charger they’d rather leave at home, the trade-off makes a fairly straightforward case.

Cables are the dirty secret of PC building. No matter how carefully chosen the components are, or how expensive the case gets, the tangle of power, data, and fan connectors that crisscross the interior of most gaming desktops eventually undermines every effort at a clean aesthetic. The glass side panel that was supposed to show off the build ends up framing a web of wires that even the most diligent cable manager struggles to fully tame.

The Maingear Zero treats that problem as the actual design brief. Its patented MG-RC, or Rear Connection, system moves every motherboard connector to the back and underside of the board, clearing the visible interior of cables entirely. Paired with a single, seamless 4 mm tempered glass curve that wraps the front and side of the chassis without a single seam or pillar, the result is a desktop that looks like it has nothing to hide, because it genuinely doesn’t.

Seven fans work to keep the hardware running at full performance without drawing much attention to themselves. A mix of standard and reverse-blade units pushes cool air in through the front and exhausts it out through a 360mm AIO liquid cooler at the top, all following a single front-to-back airflow path. The reverse-blade intakes are specifically designed so the fan blades themselves don’t interrupt the view through the glass, which is a level of detail that most cases simply don’t think to address.

All RGB lighting inside the Zero is diffused rather than sourced from visible diodes, meaning the light saturates the interior without any glowing point of origin to break the illusion. The whole package measures 236mm wide, 421mm tall, and 460mm deep, which is more compact than a traditional mid-tower while still accommodating a full-sized GPU and the 360mm cooler overhead. It doesn’t look like a PC that compromised on size to achieve the aesthetic.

The hardware ceiling is genuinely high. Configurations top out at an NVIDIA GeForce RTX 5090 paired with an AMD Ryzen 7 9850X3D or Intel Core Ultra 7 270K Plus, 32GB of DDR5 memory, and a 2TB NVMe SSD. The chassis uses standardized mATX components throughout, with no proprietary parts, so future upgrades don’t require a trip back to the manufacturer.

Beyond the hardware, the Launch Edition adds a pair of tool-free snap-in display stands inside the chassis, one for figurines and one for brick builds. The stands sit inside the case floor where passive airflow keeps whatever’s displayed inside dust-free. It’s the kind of feature that turns the interior from a hardware showcase into something closer to a display cabinet, which only makes sense given how much effort went into eliminating everything else that wasn’t worth looking at.

Every system is hand-built in New Jersey and ships with no bloatware pre-installed. Pricing starts at $2,699 for the base configuration, with the top-end Launch Edition Champion reaching $6,799. Built around the premise that nothing inside should be hidden, the Zero demonstrates how the best-looking gaming PC doesn’t have to sacrifice anything to get there.

The multi-tool has been around long enough that most people have developed a frustrated relationship with it. You carry one because having a blade, a screwdriver, and a bottle opener in one place sounds practical, and then you grumble when you actually need something. Getting to the right tool means prying at a tightly packed frame with both hands, and that dynamic hasn’t changed much in decades.

GEO, designed by Invento Design, takes issue with that familiar frustration. Rather than folding tools out from a layered frame, it uses a patent-pending rotating disc mechanism that cycles through five tools, exposing each one through a single opening. It’s a deceptively simple reframing of an old idea, and one that makes you wonder why nobody had taken this approach before.

The way it works is fairly intuitive. Outer index levers let you rotate the internal mechanism until the tool you want lines up with the access window. A sliding lock then holds the selected tool in position before you start. The whole operation happens in one hand, without setting anything down first or needing a second hand to hold the frame steady.

The five tools cover a surprisingly practical range of everyday needs. You’d reach for the blade and scraper when a label refuses to peel cleanly, the box opener when a taped-up package isn’t cooperating, the bottle opener at the end of a long day, the flathead driver for a loose screw or a stubborn paint can lid, and the string cutter when scissors aren’t anywhere nearby.

Carrying something with a blade in your pocket raises the obvious question of what happens when it isn’t in use. GEO handles this with a dedicated safety mode, a neutral rotational position where no edges are exposed. The sliding lock serves a separate purpose, preventing the mechanism from turning mid-task. Together, they make it safe enough to pocket, clip to a belt, or drop into a bag.

The form factor makes carrying it a fairly easy decision. At 53.5mm in diameter and only 8.7mm deep, GEO lands somewhere between a large coin and a watch face. The integrated belt clip adds some depth but keeps the total thickness under 15mm. It fits in a jeans pocket, clips to a gear bag, or disappears into a drawer without demanding much space.

There’s something worth noting about how it actually feels to use, too. The rotation isn’t purely functional but also incredibly satisfying. Each position clicks into place with enough tactile feedback that you know exactly where you’ve landed, and the smooth lever action makes it oddly enjoyable to cycle through even when nothing needs doing. It tends to stay in your hand a bit longer than the task requires.

The construction does a good job of reinforcing the premise. GEO’s tool body is milled from 440C stainless steel hardened to 57–59 HRC, placing it in the same material territory as quality kitchen blades. Cover panels come CNC-machined from either 6061-T6 aluminum or Grade 5 titanium, with internal hardware in 304 stainless steel throughout, a quietly serious specification for something this compact.

GEO isn’t meant to replace the full-size tools sitting in workshop drawers or on a fully loaded belt. It’s better understood as something for the other moments: the stubborn tape, the loose screw, the cord that needs a clean cut. Its compact, circular form makes it easy enough to keep close that reaching for it becomes the natural first move rather than an afterthought.
