Week 2 Progress

Disassembling competitive product

Taking apart Casio DH100 to understand and analyze design:

• Electronic saxophone, midi controlled
• Uses microphone element as wind sensor
• Necessary spit valve

Work on internal hardware setup

• 9V battery to power Arduino
• Sliding pitch sensor: combination of a spring, reel, and potentiometer
• Degree of pull -> winds spring, potentiometer -> reading of pitch
• Plan on approx. 1 - 1.5 octave (range of 13-20 semitones)

Image is early sketch of spring-reel potentiometer prototype, featuring 3D printed spring.

Necessary research into competitive products
