It has never happened to you that you have ten thousand controllers due to the amount of devices you have in your living room. Many times, because of that, we are forced to share the batteries between them, being a pain in the ass to have to remove them from one to put them in the other, that's why I bring you this hack, to be able to using a remote control with a single battery. Inside video:
Very useful also for when we only have one battery and we are desperate to watch our favourite programme (here again it comes into play if we are terminally lazy...).

digoooo ke if it is fake for a thousand reasons and apart aveis not seen in video when you put the control of the air conditioning is not encinde the screen ke has and apart the control need 3v to work and not half and above I just probrar with 6 different controls and nothing and is porke work with 3volts.
Mmm, that's one way of looking at it, are you sure they work at 3v, if so you might be right, but bear in mind that not all remotes are the same....
the spring is a fake. the aaa batteries in an aa remote control if the spring is stretched is real. PROVEN
hehe, very good, I'll try it.
Very logical, and very useful for many situations.
At first it seems silly, but when you think about it, it is more useful than it seems.
