A Mouse+A Power Bank =Rechargeable Wireless Mouse




You can combine a wireless mouse and a cellphone power bank to make a rechargeable mouse!

Step 1: Why I Do This

Those are dead batteries I used for my wireless mouse last year. If I could build a rechargeable mouse I could save the environment and some of my money .

Step 2: Material I Have

What I have is a used wireless mouse and a portable USB power bank ( tooth paste shaped, weird but small enough ).I used to try a cellphone battery but it is too big to fit in the mouse.

Step 3: Tools We Need

1. Iron

2. multimeter

3.scotch type and 502 cyanoacrylate adhesive (better to use hot melt adhesive if you have )

4.cutting-pliers is good to handle the plastic structures.

5. the cool stuff - a tiny multifunction screwdriver kit , I bought from a vendor for 3 USD.

Step 4: Detach the Power Bank

The 5v output USB terminal (it should be removed ) and there is a micro USB terminal on the other side for input .

Step 5: Get the PCB Board, Get Rid of Anything Else

Remove the USB terminal and other unnecessary parts but be careful to keep the recharging protection circuit well ( when the battery voltage is higher than 4.2V, stop charging). Use the multimeter to figure out the right soldering pads.

Step 6: Clean Room for Battery and PCB

This step should be very careful . Give enough space to your new battery and PCB but do not hurt the key structures of mouse or you have to throw everything in the garbage .

Step 7: Tough Battle for Space

At the beginning, I tried to fit the 18650 lithium battery from the power bank to the mouse. After 2 hours fighting for room , I gave up. It takes no more 1mm^3 to contain the battery.

Step 8: AA Size Lithium Battery

I ordered a red AA size lithium battery (3.7V output , 850 mAh) from taobao (I bet you could buy it from ebay). It is much slimmer the 18650(about 3 usd/pc).

Step 9: Place New Components

The AA battery makes the mouse like a ship suddenly and the PCB is well placed in the rear of the mouse.

Step 10: Connect Everything and Test

7.Wire and soldering the circuits.

DON'T OVERHEAT the lithium battery or IT MAY EXPLODE !

The means you should do it as quick as possible.

8. Testing the charging function, OK.

Step 11: Come Back to Life

Settle down everything and turn on the mouse , it comes back to life.

Aha!(forget to mention , I tested in advance , 3.7V is ok for the mouse.)

Step 12: Like a Real Mouse

Now it looks more like a real mouse than any other mouse in the world.

Step 13: Get to Use It!

1. Connect to computer by a micro USB wire to charge.

2. You can use the mouse when it's charging .

3. Definitely, without cable is better, actually, I used it to upload this Instructable .

Step 14: Finally, Name It

I call it Jude ;D because it's about "make it better". If you like it pls vote for it , thank you.

    Nice idea!

    Also can you say hello to Jude the mouse on my behalf?

    For your next mouse you should incorporate the internal components of a couple solar garden lights! Then with a couple solar panels it could charge itself for free using any light!

    Thanks for the 'ible. Well made! :)

    I use a Logitech M705 (also called the "Marathon-mouse") which runs on 2 AA-Batteries for a LONG time... And with long i mean WELL over 3 Years! They claim to have "up to 3 Years" but i use it at work day in and day out for 2.75 Years and i am still at 65% charge left. I expect a big part of the discharge comes from self-discharge of the batteries :)

    I love this mouse http://www.logitech.com/en-us/product/marathon-mo...

    Unsure if it runs well on rechargeable batteries thou... But to be honest i think my enviromental impact is much worse than 2 Batteries every 4 or so years for my mouse... ;)

    Thank you for reply!

    The mouse in this instructables is Logitech M215. It uses 1 AA batteries for about 2-4 months to run out. I think if I could bought M705 before I will not have chance to do this project';D.BTW , how many hours on average do you use M705 per-day ? I expect if we could remake M705 it could be charged every 2 years

    I work 8h 4days a week. So thats around 1536 hours a year...
    Remember that rechargeabe batteries have a MUCH bigger selfdischarge than a alkaline-battery.
    If i remember correctly, a NiMH will selfdischarge all on its own in maybe 0.5-1 year...
