Colder weather means more time indoors, and a compact heater that starts working quickly becomes useful for rooms that never quite warm up from the main system. DREO’s portable electric model, priced at $35.99 (was $40), uses a 1500-watt ceramic heating element paired with a funnel design that sends warm air farther than basic units, reaching comfortable levels in seconds rather than minutes. Users set a target between 41 and 95 degrees Fahrenheit in one-degree steps, and the unit cycles on and off to hold that level without constant adjustment.

Max Imagination set out to build a remote-controlled butterfly that could leave the ground under its own power, and ESP-FLUTTER manages exactly that. Weighing 70 grams complete with battery, the machine relies on two high-speed coreless digital servos to drive independent wings rather than a single motor and linkage. Those wings stretch thin plastic from supermarket produce bags across carbon-fiber rods, then carry roughly 50 tiny surface-mount LEDs per side wired with fine enameled copper. The result is an ornithopter that generates both lift and thrust through flapping motion while remaining light enough to stay airborne.

Apple Silicon Macs have sat outside Valve’s gaming plans for years, yet a single open-source effort on GitHub now places the company’s own ARM64 SteamOS image inside a lightweight virtual machine on those same machines. The project, called steamac and released as FX Steam Launcher, downloads Valve’s signed Steam Frame build, verifies the checksum, and boots it through Apple’s Hypervisor framework with libkrun. Once running, the familiar Steam gamepad interface appears in a Mac window, complete with controller support and CoreAudio sound, while Windows games arrive through Proton and the FEX emulator.

Stefan has watched other people talk about game feel without ever nailing the exact numbers that make a character land and jump the way Super Mario 64 does. He decided the only reliable path was to pull those numbers straight out of the original binary, check them twice, and then force a new game to match every one of them. The tool that made the extraction possible is called REA, short for Reverse Engineer Anything, an open project that lets coding agents inspect software on a local machine and return evidence instead of guesses

Most portable power stations ask you to leave them at home or in the car because their size turns every outing into a logistics problem. Jackery’s Explorer 100D measures about 4.6 by 3.4 by 3.4 inches and weighs roughly 1.87 pounds, small enough to rest in one hand or disappear into a backpack, purse, or carry-on without forcing a reshuffle of everything else you already packed.
