how to make tiny batteries to power led lights! - high drain battery
LED lights, the LEDs, were invented in 1962 by consulting scientist Nick hollyak Jr at the GE lab in Syracuse, New York.
At that time, he predicted that they would replace Edison's standard incandescent lamp.
Now, they are really slowly replacing light bulbs with low efficiency, high energy consumption, and high emissions.
A few years ago, at the school science fair, it was difficult for students to light one of the exploding lights with five or even six lemon batteries.
Even so, they will only send a faint light, and will not impress millions of people.
Well, maybe not millions, but, you see.
Now, at science fairs around the world, these mini heaters are mostly replaced by LEDs, but still need 3 or 4 lemons to light up one.
As a student, I also started to change this myself and start to change the world!
I forgot how I thought about it, but oh, okay!
Anyway, here I will teach you how to make small batteries to power LEDs. The Stuff!
Great!
This is a list of what you need! Tool Stuff:-Lighter (
I used a cheap laser lighter I made with Kipkay's instructions)-
Something about ScissorsProject :-LEDs! -Iron Nails (
Make sure they are not galvanized)-
Alcohol preparation pad (
You can use wet paper towels, but I prefer these)-Copper Wire (
I use the enamel magnet line)-Salt-Water-
CupI believes this is all you need!
In this step, we will make an electrolyte for the battery ,(
Actually, we just need to put salt on paper).
Anyway, start with the cup and pour 2 ounces of water (
I just made it up)
Or just a little bit.
Then, pour a pile of salt and mix.
The point is to prepare saturated salt solutions for our electrolyte (
Because this is what plants desire! ).
Let's talk about it later.
So, basically, this step is interesting (
If you choose to use the alcohol preparation pad, if not then no).
Anyway, first wrap the nails on the mat.
Once you do that, put it in a non
Flammable surface, make sure it is tight and ignite it!
Once the flame turns yellow (if), blow it out.
If you use something like paper towels or paper, wet the paper first, which will be easier.
It's time to power it up!
So simple, but so easy.
Dip the nail/paper stuff into salt water and wait for it to dry.
Repeat 2 or 3 times.
Another simple step, cut off your wire for about 2 or 3 feet.
Wrap this tightly on paper and don't let it touch the iron.
According to my calculation, each unit issues a half volt voltage, which means that you need about 6 units in series to power the standard 3 volt led.
This system is not very good for one LED power supply, but it is better for 2 or 3 LED power supply in parallel.
Unfortunately, my phone died before I took this step, so there were no photos. Sorry.
However, the flexible camera of the phone is the reason why the photos are not good, and I am sorry about this.
Edit: I just realized that for a cell or two, it is possible to get away with the penalty by using the Joules thief.
