Here are some photos and notes from the assembly.
- Soldering the micro switches to the matrix board as well as the ground wires.
- Connecting the switches to the corresponding pins on the Lilypad (here: ground as well as fast-forward/backwards switches).
- Connecting the 5 playlist switches to the corresponding trigger pins on the Lilypad.
- Making sure the bottom of the Lilypad is protected when placing it above the matrix board.
- Connecting potentiometer, battery and speaker and running some tests.
- Bezel for the speaker grid.
- Front plate with holes for buttons and speaker. It was a bit tricky to get the holes right so that the keycaps fit neatly without getting caught. File to the rescue.
- Frame parts and handle. It's hardwood (beech), so it is recommended to pre-drill holes for battery holders and handle.
- Holes for power switch and potentiometer. On the inner side, the holes were broadened with a hole saw because switch and potentiometer need a lot of space.
- Putting all parts together using wood glue.
- Mounting power switch and battery holders. Power wiring. Using spacers to make sure the keycaps have the right height on the outer side.
- Inserting and fasting potentiomer, board and speaker.
- Again, power switch and volume potentiometer from both sides. The shaft of the potentiometer needs to be shortened so that the knob fits correctly.
- Completed.
