Journal With Power Bank and Wireless Charger

This project has been made for the Instructables contest on Books and Bookshelves.

A journal is a very useful tool for self-improvisation. Writing a journal can make you understand the mistakes that you did in the day. It can also set a plan for the next day, which makes it really useful. But, writing a journal every day is not an easy task. You need to have the consistency and will power.

Today, I will be making a power bank inside a journal, so that you can charge any device and it will also be a reminder to write a journal entry. As it is a power bank, you will most likely carry it wherever you go as a backup to your phone.

We will also adding a wireless charger to it, as I really like the simplicity of the wireless charging technology and I have a wireless charging module with me for a long time.

So, let's start

For this project, you will need: -

• 3.7v Lithium Ion Battery
• USB module
• Micro USB port
• USB ports (Salvage from an old USB Hub)
• Wireless charging module
• USB (Type A)
• Wires

You will also need some double-sided tape/ superglue to stick the electronics.

(If it is not clear, read the next few steps, where I will tell everything in detail)

Micro USB: -

Live: + Pin of USB Hub

Ground: - Pin of USB Hub

USB Hub: -

(To Micro USB as mentioned before)

USB Module: -

Live: + Pin of Battery

Ground: - Pin of Battery

Wireless Charging Module: -

Live: + Pin of USB

Ground: - Pin of USB

So, in the Micro USB port, there will be 4 (or 5) pins. We will only need the live and the ground.

The live wire will connect to the USB Hub's positive terminal.

The ground wire will connect to the USB Hub's negative terminal.

USB Module is not the same as USB Hub. USB module converts the 3.7v from the battery to 5v, whereas the USB Hub doesn't. The module also can recharge the battery when connected to another power source through it's input port.

Here, you get 2 pins, live and ground.

The live wire should be connected to the positive terminal of the 3.7v battery (make sure it is rechargeable).

The ground wire should be connected to the negative terminal of the battery.

Generally, wireless charging modules end with an input USB port. But the one I had did not have the port. Instead, it had a live and a ground wire, which is also fine.

• Wireless Charger Without Input Port

You will need a USB cable. Cut the outer covering of the cable, make sure not to cut the wires inside. You will see many wires and maybe, a metal braid. Cut everything except the red and black (it could also be blue) wire. The USB will look somewhat like in the picture given above.

• Wireless Charger with Input Port

For modules with the input Micro USB port, you can just connect a Micro USB - Type A cable and continue.

So, I will explain what I have made until now. It can be divided into 3 separate circuits: -

1. The Micro USB - USB Hub: For the wireless charger and three USB Type A output ports. When the Micro USB is connected to a power source, it gives power to the USB Hub and the wireless charging module.
2. The USB Module: It is for charging and converting the 3.7v from the lithium-ion battery to 5v. It can power two devices at once.
3. The Wireless Charging Module: It is connected to a Type A cable, which allows it to switch from the USB Hub to the USB module. So, that means you can take power directly from the USB Hub or from the power bank.

I made 3 different circuits because if we wanted to charge a phone wirelessly but through the power bank, then this will be easy as the wireless charging module is connected to a USB cable.

Use double sided tape, to attach the hardware onto the back cover of the book.

In the demo, the power bank was getting charged. After a considerable amount of time, you will be able to see 3 or 4 LEDs lit. This means that it has charged sufficiently.

Make sure that the phone, which is being used has wireless charging technology, otherwise it won't work. The phone which I used is Samsung s23, which has the wireless charging technology. (Old phones most likely won't have wireless charging capability).

Now, we have come to the last phase of the project, which is to start writing the journal. Daily, before going to sleep, plan your next day and write about the current one. It can be about how much calories you ate, how much water you drank, or even all the work you finished. It is boring, but it is crucial for success. Remember, if you have a plan and have a clear goal in your mind, then you are much likely to succeed than if you don't.

I hope, you found this project interesting. Please, comment if there is any mistake from my side. If there is any query regarding the project, please ask in the comments, I will try my best to clarify them.

Happy Building!
