Introduction: How to Make Mouse Charging Dock
The best thing that happened to the technology is a wireless mouse, but when I have been using wireless mouses, I realized something very terrible and annoying, that when the mouse empties suddenly and you are working or playing, so I decided to make a charging dock to my wireless mouse.
I made many designs but after searching online I found some mouses have a charging dock and the only one I like its design is Razer Viper Ultimate and I feel it's easy to make it at home.

This charging dock is easy for everyone to make at home with simple materials, you need:
- For cutting acrylic sheet (Router CNC, Laser CNC, or print the file on paper and cut it using a hand saw)
Step 1: Circuit
For this project, I used Energizer NH15 1.2v NiMH - HR6 1400mah battery, and tried many chargers for this type of rechargeable battery, but most of them may damage the battery because it still charging it until you take it.
This type of battery nickel-metal hydride battery (NiMH) has some features in charging mode, you can charge it in fast mode and slow mode, that if you charge it at a low rate like 200mAh you can leave it for a long time without damaging the battery you can leave it months but less than a year.
So I used the TC4056A charging board, that is for a 3.7V lithium-ion rechargeable battery, but I changed the output current by replacing the charging current controlling resistor (R3), I used a slide switch to switch between slow and fast mode.
Slow mode: 5K Ohm, 250 mAh output current, ~ 6.5 hours
Fast mode: 1.2K Ohm, 1000 mAh output current, ~ 1.5 hours
Warning: this circuit depends on time and the capacity of the battery because it doesn't have a cutoff, but if you charge the battery at a low rate like 200 mAh you can leave it for a long time without damaging the battery, this option only for NiMH battery
Step 2: Make Mouse Ready
My wireless mouse is A4TECH Model: G10-810FL, and I love it.
There is a place for the receiver inside the mouse, but now it's empty and it has no use, so I used this gap to add the connectors.
I connected the connectors and the battery with wires inside the mouse and added two magnets to secure the mouse and the connection with the charging dock.
Step 3: Charging Dock
I used an acrylic sheet, black 2mm thickness in making the dock, that cut by my router CNC.
I sanded the body to make it like one piece and to make it matt and have a nice finish.
It is a very strong body, don't worry about breaking it.
The cutting file uploaded in DXF if you want to make it like this charging dock.
Step 4: Connecting
Here we have the body and the circuit ready to combine together.
The connectors I used to have a spring to make the connection with the mouse smooth and still pushing the connectors in the mouse.
Also, I added two magnets inside the body facing the magnets in the mouse, so no need to center the mouse on the charging dock and no slide out from the charging dock.
There are two LED lights in the front, blue is standing by, and red is charging, so don't worry if the mouse not connected correctly.
Step 5: Final Test
Finally, I am very satisfied and surprised by the results, it is an amazing charging dock, I feel like it isn't made at home.
The connection is very accurate and no need to adjust the mouse, it is solid and stylish suitable on every table.
