We can make a rechargeable mouse by re-assembling an old wireless mouse with a mobile charger. You don’t have to buy and throw away any batteries but simply recharge this mouse by connecting it to your computer using a cellphone’s USB cable.
Step 1: Why did I choose to do this?
These are the depleted batteries used by the mouse last year, which not only damages the environment but also costs lots of money.
Step 2: Materials: an old wireless mouse and a cellphone’s mobile charger
I intended to use an old cellphone at first, but I gave up this idea because the cellphone’s lithium battery was too big. I happened to have a toothpaste-shaped mobile charger in the tooth-paste shape on hand, so I chose that instead.
Step 3: Tools required
1. Soldering iron
3. Tape (the hot-melt adhesive is better, but I didn’t have it on hand.)
4. 502 glue
5. Beak strippers (easy to cut the plastic)
6. Small multi-purpose screwdriver
