Software apps and online services
I usually use smartphones frequently. But I was uncomfortable because I could not use my smartphone due to lack of battery. So I thought I'd make a portable charger myself and use it! This can be made without using Arduino. But you can also use Arduino to use a variety of functions!
Prepare the AA battery holder, AA battery, DC battery, DC state-up voltage conversion module, and the conversion module! And you need 3D design!Step-by-step instructions
We prefer AA rechargeable batteries to AA batteries, but we'll use the batteries here!
I'll explain it based on the 3D design that I created myself. First, insert the battery holder into the box on the left side and glue it with glue!
Then place the + and - line in the battery holder in a small hole on the left.
Then the wires should be brazed to the DC-DC module, so be careful not to get hurt!
When soldering is finished, insert the DC - DC module into a small hole and glue it with glue!Conclusion
So I built my own portable charger. It's easier said than done, but it's a little hard to make.
Of course, the batteries are low in voltage, but they charge faster if they use rechargeable batteries to charge them faster! It is not easy to introduce my first piece of work. Next time, I will visit something more interesting!
