Introduction: Make Wireless Charging Mouse

I prefer wired mouse to wireless mouse for one reason, which is about battery. It feels inconvenient for me to look for the charging machine to charge up a dead battery or purchase new battery when it is discharged. Sometimes it goes bad at inconvenient times.

I found wireless mouse not used for sometime in my room and decided to make an wireless charging mouse for myself.

First, you can purchase the inductive charging set online(follow this link). With this module, you can upgrade your wireless mouse into your own wireless charging mouse.

Step 1: The Methodology

When it comes to the wireless mouse with 3V (uses two 1.5V batteries), the inductive charging receiver makes 5V DC output and it flows into LiPo charger module. LiPo charger module charges LiPo battery and prevent over-charging (and over-discharging). Also we can draw power from LiPo charger module to activate the mouse.

Step 2: Gather the Components

the components and tools for this job:

  • wireless mouse
  • inductive charging set (input 5~12V, output 5V)
  • LiPo charging module
  • LiPo battery
  • power source(5~12V)
  • soldering iron and accessories
  • screw-driver
  • etc

In the photo above, you can also find major parts that you need to prepare.

Step 3: Open Mouse Cover

You can see the circuit like picture above when you open mouse cover. Remove the AAA battery space and we’re going to locate parts in it. The red and black line is for the power source.

Step 4: Connect Each Part

I used LiPo charger module below. It has connection holes for battery, power input and power output (for mouse in this project).

  • +, – holes in left side is for the external power source(5V). Connect both to inductive charging receiver.
  • B+, B- holes in right side is for the LiPo battery's +, -.
  • OUT+, OUT- holes in right side is for the mouse. The red and black lines in your mouse should be connected to each of these.

Step 5: Solder Parts and Test

I’ve soldered parts like picture below. To turn it on/off, I added a button at LiPo battery power line.

And I tested if wireless charging parts works well or not. Above picture is inductive charging transmitter. I connected this to power supply with 12V setting.

When transmitter and receiver’s coils are getting close, LiPo charger module turns red LED on. You can see the blue LED when battery is full.

At this time I found that this white mouse is out of order. So I changed the mouse with another one. At below steps you can see the black one.

Step 6: Locate the Parts in Mouse

I made space for the wireless charging parts by removing the AAA battery area. To be more effective in wireless charging, locate the receiver’s coil at bottom.

And check again if wireless charging is working. If there is no problem close the cover.

Step 7: Make Parking Pad

Hide inductive charging transmitter under the mouse pad or anything else.

Now you are free from battery!!

Hey guys,i know this is dumb but what volt is the LiPo battery capacity or something like that?

Volts: A lipo battery has 4.2 volts when fully charged and 3.7 volts when safely discharged. If it gets discharged under 3.7 volts, it gets damaged.

Capacity: This exact one is 240mAh, meaning the device can "eat" 240 miliamps for one hour. That being said, you can purchase any sized battery, as long as it fits.

Can i use this method to Qi charge a Xbox One controller?

I love this idea :) I will do this mouse pad and I got new ideas from here:

http://cuddle-cuddle.com/

I'm not sure if I would tamper with a $60 controller. You could try to make a wireless plug that could plug into your controller, but still: damage could be done without the proper voltage and amperage that the controller is acclimated to.

thats right, but there should be ways to improve our decrease the output.

would using a 12v wireless output be bad AKA destroy the battery or device, cause im thinking about doing this for a nighttime charging stand.

Put that under the mouse mat and the mouses battery never dies

could you do this with just nimh batteries? and use a resistor as a simple charging circuit? I would love to do this with my PS4 controllers (li ion i believe) and my rechargable batteries in my remotes :)))
