Description

If you want to make your own cassette case for FiiO M21, this project is for you.

You'll need to do soldering and play with magnets but it worth it !

Just follow my beautiful artworks !

  • 6 push-buttons 6 x 6 mm, 5 mm thickness
  • 2 blank PCB 2mm thickness (104.5 x 14.5 mm and 10.5 x 5 mm)
  • 6 resistors : 560 kΩ (volume +) ; 220 kΩ (volume -) ; 120 kΩ (next) ; 82 kΩ (prev) ; 47 kΩ (play/pause) and 1 kΩ (On)
  • 3 pogo pins 2 mm
  • 3 round magnets 8 mm diameter 2 mm thickness
  • 2 round magnets 6 mm diameter 3 mm thickness
  • 3 adhesive pads 9 x 4 mm , 1.5 mm thickness (you can print them in TPU)
  • 2 metal rods (I use nails) about 2 x 25 mm 

The magnet on the back is used to “unlock” the serial port at the back of the Fiio M21 so, if you slide it, it will act like a “Hold” button.
