• A small rechargeable battery (like a 3.7V 14500)
• A USB charging module (TP4056)
• A diode (e.g., 1N4007)
• A bit of patience

Just solder the battery wires where the originals were, install a USB port on the back, and voilà—no more swapping batteries.

Feeling advanced? Add Bluetooth with an ESP32 and reprogram the board.

Bonus: It’s better for the planet. Fewer disposable batteries, more sustainable living—and a remote that works when you need it.
