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!!

<p>Can i use this method to Qi charge a Xbox One controller?</p>
<p>I love this idea :) I will do this mouse pad and I got new ideas from here: </p><p>http://cuddle-cuddle.com/</p>
<p>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. </p>
thats right, but there should be ways to improve our decrease the output.
<p>I'll try</p>
<p>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.</p>
<p>Hey guys,i know this is dumb but what volt is the LiPo battery capacity or something like that?</p>
<p>Put that under the mouse mat and the mouses battery never dies </p>
<p>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 :)))</p>
<p>or could you use a capacitor and do a battery delete with a mousepad with magnetic induction?</p>
would it be possible to make the transmitting coil around the entire mouse pad so that the entire pad would be the charging station for it? <br><br>i would still leave the battery as a back up, just an idea.
<p>why the battery ??</p>
<p>Great idea - I can see how this would be a great adaptation to my Mac desktop's Magic Trackpad (non-integrated - large, external trackpad) The best part is the Both loops could fit right under the incline it is designed to sit at.</p>
<p>I'm expecting your work. Please share the result when you have done it.</p>
Will likely be awhile - major projects on the table right now need finished.
<p>Nice one! I have an old Microsoft wireless mouse that uses two AA batteries, has no switch and is not smart enough to turn itself off so it runs out of juice about every two months. To save money I use two sets of NIMH batteries and a separate charger so one set is always ready to go when I need it. I also have a much cheaper Gear Head wireless mouse that uses two AAA batteries, has a switch and does turn itself off, but lasts almost a year before it needs new batteries. This wireless charger circuit would be a great addition to the MS mouse, not so much for the Gear Head as the added electronics would double its cost, but the freedom from ever changing batteries might make it worthwhile. </p><p>By the way, if you're tired of cleaning mouse pads and mouse feet I've found a great solution for that problem. Use a small white nylon cutting board instead. A set of three in varying sizes costs something like $10. The smallest one is too small for a cutting board but the perfect size for a mouse pad. It's very slippery and dirt and skin cells don't stick to it. It's also thick enough for you to hollow out the underside to fit the wireless charger coil. I also put some feet on the bottom in the form of small stick-on Velcro pads (the loop part) to keep dirt from getting caught under it and scratching my desktop. </p>
<p>Thank you for the advice. I think it'll be better if I can make parking pad transparent. Easily I can find where to park for charging.</p>
<p>brilliant and simple idea. why isn't it commercial?? </p>
<p>This is perfect. Creating a mousepad with the coil inside or even embedding it in your desk would be awesome too!</p>
<p>came to say that +1</p>
<p>good wireless project!</p>
Excellent project! I haven't used a wireless mouse because of the usual charging/battery issues but I like this idea.
<p>This is a wonderful idea! Your mouse is going to be sitting around the same spot all day so it's not an issue of it wont charge or not. </p>
