Glorious launches GMMK Eternal, a $99 compact mechanical keyboard

Glorious has released the GMMK Eternal, a wired mechanical gaming keyboard with a 96-percent layout that squeezes a numberpad and full function row into a compact frame. It ships in black with hot-swappable Fox MX linear switches, ABS double-shot keycaps, RGB backlighting, and three layers of internal sound dampening, priced at $99.99.

Fable 5 AI autonomously designs a working RPi Pico 2350 e-ink PCB from a text prompt

A hobbyist asked the Fable 5 AI tool to design a printed circuit board pairing a Raspberry Pi Pico 2350 with a GDEY0154D67-FL04 e-ink display, four buttons, and exposed I2C and GPIO pins, using only a single plain-English prompt. Unlike an earlier attempt with Claude Opus 4.8 that botched component orientation and routing, Fable 5 worked unsupervised for a few hours and produced a completed 31.8 x 37.32mm four-layer schematic and layout via KiCad's MCP integration, with no manual edits or checks from the designer before manufacturing.

Engineer builds NFC business card with phone-powered LED, no battery

A developer designed a credit-card-sized PCB business card featuring an NFC chip that opens his website when tapped and a red LED that lights up on a printed Charizard's tail, powered entirely by the phone's own NFC radio field rather than any onboard battery. He had to write a custom Core NFC app for iPhone because standard NFC apps couldn't write to the blank NTAG I2C Plus chip he used, so his app sends the chip's native write commands directly.

Brazilian YouTubers solder power cables directly onto RTX 5090 PCB as protest fix

TecLab modified a Galax RTX 5090 D HOF OC LAB XOC by bypassing its 16-pin power connectors entirely, soldering wires straight to the PCB's power traces and replacing the stock cooling with an industrial water cooler. Power meter readings suggested the card was drawing roughly 600W, well within the card's 2,000W custom BIOS limit, though final temperatures were not disclosed. The team clarified the stunt was a sarcastic jab at Nvidia rather than a genuine repair method for regular users.

Taiwan prosecutors probe Unimicron over alleged mislabeling of China-made PCBs

Taoyuan prosecutors raided Unimicron Technology's headquarters and a plant, questioning 14 staff over allegations the company relabeled China-manufactured circuit boards as Taiwan-origin products. Several executives were released on bail ranging from NT$300,000 to NT$15 million, and the investigation into possible forgery and false origin-marking continues.

Engineer builds battery-free NFC business card with animated LEDs and onboard MCU

A hobbyist designed a PCB business card that uses an NFC chip's energy-harvesting capability to power 21 LEDs and an ATtiny412 microcontroller, all without a battery. Tapping the card against a phone triggers an LED animation, drawing power solely from the phone's NFC field via chips like the NXP NTAG I2C Plus or STMicro ST25DV-KC that can route excess harvested voltage to external components. The creator built the project in about three months as a way to learn KiCad, and has published the full design files publicly.
