The device houses 144 amber-colored LEDs mounted on a 10-inch board, drawing power continuously through a dedicated USB-C port without an internal battery. Instead of relying on looped animations, an Espressif chip calculates real-time light patterns trained on video of genuine candle flames. Because the platform is fully open source, owners can rewrite the firmware to repurpose the amber display for utility functions or entirely different retro visual simulations.

After engineering a flexible version of Tetris that could be wrapped around a magazine, Kevin Bates’ latest creation is a digital candle that uses a custom AI model to accurately simulate the appearance of a flickering flame across a grid of LEDs. It’s a far cry from the types of devices Bates is typically known for, including the Arduboy, but paying $79 for a credit card-sized handheld that can play hundreds of games is an easier sell than a $149 digital candle that doesn’t quite provide the same ambiance as the real thing, even if it’s much safer.

At the top of the 10-inch tall Digital Candle, which is available now with a black or white circuitboard, you’ll find 144 amber-colored LEDs arranged in a 9 by 16 grid with adjustable brightness. On the…
Retailers Amazon and Walmart are offering an early purchase promotion on the physical cartridge edition for Nintendo Switch 2 ahead of its November 5 launch. Securing the game before next Thursday locks in standard pricing before the retail price increases by ten dollars. The release brings modernized controls and overhauled visual fidelity to the classic Nintendo 64 adventure.
Watchdog Ofcom found that roughly 150,000 older adolescents lack a passport or driving licence, which are expected to serve as vital backstops for verification systems. Because biometric tools like selfie facial scans remain imprecise by several years, young people without official documentation face digital exclusion. The looming restrictions aim to enforce an under-16 platform ban scheduled to take effect next spring.
The social platform intervened after a hacker extracted agency login records exposing names, official phone numbers, and work emails for personnel at ICE and CBP. Platform moderators chose to target the transparency collective's web address directly instead of deleting user posts that referenced the breach. Federal officials are simultaneously attempting to suppress the leak across the internet using outside contractors to neutralize host domains.
