Are you sick and weary of rushing to the store each time your batteries die? Yes, I agree. That is, until I came across a hack that revolutionised my use of remote controls. The best part, too? Doing something yourself is easy, inexpensive, and a lot of fun.
A small issue with a substantial budget is the battery dilemma.
You are anticipating the beginning of your favourite movie while lounging on the couch. and your remote doesn’t react. The batteries have died once more. We are unaware of the unforeseen cost of those tiny batteries, which mount up between the TV, the fan, and the children’s toys.
Why not change the batteries once and for all rather than purchasing more ones?
How to make a rechargeable remote control at home
It’s a surprisingly easy fix. In order to convert your standard remote control into a rechargeable device, you will require the following:
A little lithium-based 3.7V rechargeable battery, like a 14500 or similar
A USB charging module (TP4056 type, readily available in internet marketplaces)
To change the voltage as necessary, use a diode (such as a 1N4007).
Just a little perseverance will do!
The ordinary batteries are to be taken out and the battery wires soldered in their place. A tiny micro-USB or USB-C port on the casing, like on the rear, will allow your remote control to be recharged like a smartphone. Easy, huh?
In case you were wondering, here is the Bluetooth version.
Do you want to do something more? A remote control can even be made to function as a Bluetooth-enabled gadget. It takes a little more expertise to use this method because you have to completely reprogramme the circuit and integrate a microcontroller (such an ESP32).
This trip is also appropriate for people who like do-it-yourself projects and gadgets. But if you just want to do away with the need for batteries, the first solution is good enough.
A tiny gesture on your part, a significant stride for the earth
Hundreds of millions of batteries are thrown away annually in France. Their manufacturing is extremely energy intensive, even if they are partially recycled. A concrete step towards a more responsible lifestyle is selecting a rechargeable remote control, even for a basic everyday item.
Using something you’ve made yourself also gives you a real sense of accomplishment, let’s face it. It is giving a quiet roommate new life.
