Introduction: Rechargeable Wireless Mouse

About: DOING ROBOT PROJECT

Hi guys recently I buy wireless mouse ,for switch on the mouse we want AAA size battery. I used continuously for PC within 3 weeks battery discharged .so I decided to do rechargeable wireless mouse.

Step 1: Material

@ IN 4007 diode -1
@ LED ( red colour for charging
indication)-1
@ charging connectors -1
@ lithium-ion battery (800-1500mah)
@ 470 ohm resistor-1
@ hot glue
@ PCB board

Step 2: CIRCIUIT

make it circuit on pcb board with components, make it small to fix inside the mouse.

Step 3: Cut Out

make a cut out to fix the connector .using hot glue.

Step 4: Assemble

fix inside the battery as per circuit image.

Step 5: Finish

I did not image the PCB board fixing in mouse because that I cannot have camera .u can try it as per circuit if any doubt ask to me..

    Be careful! A Diode is not a proper Li-Ion charger. A Li-Ion battery needs a special charging circuit (Constant Current, then Constant Voltage) The cell could explode if its charged too long.

    we want to maintain the charging time 1-2hours

    Cool! The design it quite clever, and you explained it very well. Thanks for sharing!

    Does the rechargeable battery that you used has an internal circuit to manage charging? Otherwise, the circuit that you designed I do not see how it can properly charge a lithium battery, since the charging process is quite complex. The circuit you posted I guess is to charge a lead acid battery. Am I wrong?

    no it only to charge lithium battery
