Since regular DVD rewinders are so expensive I designed a simple cheap DVD rewinder you can make yourself.
Step 1: Parts
-A Small Cardboard Box
Step 2: Wire Up the Motor
Get your motor (I found mine in a thing) and attach wire to it.
Then, attach one of the wire to one end of the battery.
Step 3: Finish Him.
Attach the motor to the side of the box with some tape.
Step 4: How to Use It
1. Take the DVD you want to rewind and put tape over the center hole.
2. Stick the tape to the motor, make sure it's on the part that spins.
3. Attach the unattached wire to the free side of the battery.
4. When it's done rewinding remove the DVD for use.
WARNING! Make sure you spin it to the left, to rewind it.
Momsen Design made it!
