CNX Software ☛ HackLED Pro LED controller – An Adafruit Sparkle Motion alternative with WS2812 and RGBCW LED support
HACK Lab HackLED Pro is an Adafruit Sparkle Motion-like LED controller that runs a custom version of WLED and supports both WS2812 and RGBCW LEDs, making it ideal for DIY lighting projects, smart home setups, and audio-reactive light displays. Built around an ESP32 MCU, this board includes 2-way WS2812 LED outputs, 5 PWM channels (RGBCW), and an onboard silicon microphone for music reactive LED setup. Like the Sparkle Motion, the outputs of this board are level-shifted, and there’s also a power switch that toggles the output power between 5V and 12V. The board features a USB-C port with a PD controller, with which you can power and program the board. The controller is housed in a thermally protected 3D printed case and is also compatible with the generic version of the WLED firmware.

Hackaday ☛ Fission Simulator Melts Down RP2040
We’ve seen a lot of projects based on the Pi Pico, but a nuclear reactor simulation is a new one. This project was created by [Andrew Shim], [Tyler Wisniewski] and another group member for Cornell’s ECE 4760 class on embedded design (which should silence naysayers who think the Pi Pico can’t be a “serious” microcontroller), and simulates the infamous soviet RMBK reactor of Chernobyl fame.

Hackaday ☛ Game Boy? NES? Why Not Both!
If you’re a retro Nintendo fan you can of course carry a NES and a Game Boy around with you, but the former isn’t very portable. Never fear though, because here’s [Chad Burrow], who’s created a neat handheld console that emulates both.
