Are you interested in DIYing a USB charger? [Copy link]

 

Some time ago, I DIYed a transparent multi-port charger . Although it is convenient to use, I cannot directly see the charging status, so I want to add a display screen and sensor to display the charging voltage, current, and temperature, and to count the charging time and charging capacity, making it more practical. Are you interested in DIYing one together?

If there are many interested netizens, they can discuss the DIY process together, improve methods, reduce costs, add different functions, and share ideas.

So, you write a paragraph, use some software, draw pictures, and what are the basic requirements? We build a github library to synchronize, and then everyone can play together.

Why not go a step further and get an outdoor power supply, similar to the one from DJI?

This is an Ac-Dc, it is better to change it to a battery mode, which supports up to 120W output, and can charge mobile phones and computers

This is fine, we just need to communicate together.

The outdoor power supply requirements are relatively high and the cost is also high, so you can come back later, starting with the easy ones and then moving on to the difficult ones.

Fast-charging power banks are also available now, but they are less playable and are all semi-finished kits that are not easy to DIY.

Gitee, I can't access github on my computer, so I can't play

Yes, I am not good at software, but I can help you draw PCB

Add me, I can design software and interface

Prepare to use OLED, the screen is relatively small, and the interface may not have too many features, but it can be viewed through the Internet.

Want to create a WebServer service?

Come on, let's come up with a catchy name.

What should I call it?

Ok, gitee is also good.

Prepare to use esp32 so that you can run a simple webserver and view the status with a browser.

We also plan to add RTC to record charging time and status, so it would be nice to have a dedicated software. Of course, other methods are also possible.

It’s difficult to name something, you should think of one first.

Does the ESP32 RTC need a crystal oscillator? That would increase the cost. Is the microPython RTC not yet implemented?

Make a special software, like Hezhou's CC, it's really good~

If you have software, you can count me in.
