Today, a large percentage of people have a personal computer at home. Today we bring you a very interesting article with which you can take advantage of the hours you spend in front of the screen to recharge your batteries..
First of all, it is important to note that this invention will only be used for the following purposes AA rechargeable batteries. Normal batteries cannot be recharged.
The electronic components we will need to assemble our circuit are as follows:
- A TIP32C integrated circuit.
- Six resistors:
o R1 = 56k
o R2 = 27k
o R3 = 22k
o R4 = 47k
o R5 = 750
o R6 = 220
- LED diode.
- 0.1 µF ceramic capacitor.
- An LM393 integrated circuit.
- A battery holder.
- Printed circuit board.
Well, after getting all the necessary elements to carry out the assembly, we will proceed to assemble them all. The first and most important thing is to make the circuit that will allow it to work. In this article you can see how to assemble a printed circuit board on a plate. The schematic diagrams for the implementation are as follows:
Location of components
Once we have the circuit ready, all that remains is to incorporate the battery holder and the USB cable. In the following image you can see where each cable will be placed:
After making these last changes, we will get a result like the following:
As you can see, the assembly is quite simple and we won't spend more than 5 euros to buy the components. If you have any doubts, you can go to the forum and we will solve them without any problem.
