Sick of constantly replacing batteries? Here’s an easy DIY trick: turn your remote into a rechargeable device.
What You Need:
-
3.7V rechargeable battery (like a 14500)
-
TP4056 USB charging module
-
1N4007 diode
-
A bit of soldering and patience
How it works: Replace old batteries with the rechargeable one, wire in the charging module, and add a USB port to the back. Now you can just plug it in—no more battery runs.
Want More? Go Bluetooth
Feeling techy? Add an ESP32 microcontroller and turn your remote into a Bluetooth device. It’s more advanced but great for smart homes.
Why It Matters
You’ll save money, cut down on waste, and feel awesome using something you built. A small fix with a big impact.
