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
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.
