DIY Tape Drive:

• Keep the core-rings remaining from sticky tapes that you use.
• When you are about to finish your fourth, save some tape
• Peel the remaining tape and encircle 2 of the core-rings
  • Do the same with the other 2 core-rings and remaining tape
  • You might want the amount of tape used to be same for both the pairs
• Connect core-rings to the axle of your choice
