Charging station for wireless computer mouse

Charging station for wireless computer mouse  Charging station for wireless computer mouse Charging station for wireless computer mouse  Charging station for wireless computer mouse Charging station for wireless computer mouse A wireless mouse is more convenient than a classic wired one. Unfortunately, it has one big drawback, at the most inopportune moment the battery is discharged and the mouse stops working.
Some manufacturers have solved this issue by installing a battery instead of a battery and adding a charging station to the kit. Unfortunately, the prices for such mice are not the smallest.
The master decided to make a docking station for his mouse on his own, and as a design he considered a wireless mouse with a Razer Viper Ultimate charging station.
 Charging station for wireless computer mouse Tools and materials: -Black acrylic sheet 2 mm thick;
-CNC machine;
-Soldering iron;
-Super-glue;
-B7000 glue;
-Emery paper;
-Mini drill;
-Wires;
-NiMH rechargeable battery 1.2 V 1400 mAh; -Charging module TC4056A; -Resistor 5kOhm; -Resistor 1.2 kOhm; -Switch; -Two neodymium magnets in the form of an arc ; -Spring connector;
-Springs;
-Pins;
-Terminals;
Step one: diagram
For this project, the master used an Energizer NH15 1.2 V – HR6 1400 mAh NiMH battery. He has tried several chargers for this type of rechargeable battery. They generally continue to charge the battery even after being fully charged.
This type of battery has some peculiarities in charging mode, it can be charged in fast mode and slow mode. If it charges at a low rate, such as 200mAh, you can leave it for a long time without risking damaging the battery.
The device will use the TC4056A board for charging. It is designed for 3.7V Li-ion battery, but it changed the output current by replacing the charge current limiting resistor (R3). Also used a slide switch to switch between slow and fast modes.
Battery charging time and resistors are as follows (true for 1400mAh battery):
Slow mode: 5kΩ, output current 250mAh, ~ 6.5 hours
Fast mode: 1.2 kOhm, output current 1000 mAh, ~ 1.5 hours
Warning: This circuit is dependent on battery capacity because it has no cutoff. If you charge the battery at a low rate, for example 200 mAh, you can leave it on for a long time. This option is for NiMH battery only.
Wires are soldered to the board according to the diagram and photo. Additionally, in parallel with the power connector (USB), solder another connector and LEDs.

The docking station is made for the A4TECH wireless mouse Model : G10-810FL.
There is a place inside the mouse where the receiver was stored. You can use the empty space to modify the mouse.
The mouse must be disassembled first.

Solder wires to them and solder the other ends to the contact pads of the board at the battery power input (BAT + and BAT -). Installs the battery. Assembles a mouse.

The case is made of 2 mm thick black acrylic. First, he designed the body parts in a graphics program. Then I cut it out on a CNC machine.

Now you need to mount and install the electrical parts in the case.
On double-sided tape stick the charging board inside the case. Attaches a remote connector and a switch to the housing bore. Two LEDs, red and green, are brought to the front panel to signal charging.
