The fix? Make your remote rechargeable.
You’ll need:
- 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.
