HarmoNeo Work Journal
HarmoNeo merges classic harmonium acoustics with microcontroller-driven bellow emulation for portable, cost-effective dynamic play.
MAY DIARY
HarmoNeo employs a microcontroller-driven digital potentiometer to electronically replicate the traditional harmonium’s bellows mechanism.
LEARN MOREJUNE DIARY
In June, the HarmoNeo team transitioned from concept to hands-on practice by learning Arduino fundamentals and running LED blink exercises to validate digital I/O control.
LEARN MOREJULY DIARY
In July, the HarmoNeo team progressed from LED demos to full X9C104 integration, validating digital potentiometer control via bench measurements and firmware-driven step sweeps.
LEARN MOREAUGUST DIARY
In August, the HarmoNeo team implemented closed-loop bellows control, mapping real-time analog sensor inputs to the X9C104 and adding MIDI-based dynamic expression.
