Working
hardware.

Six working devices across four case studies, spanning embedded DSP, USB MIDI, analog audio electronics, interface design, soldering, and enclosure fabrication.

01

Flagship / Embedded audio

BonesFX

A dual-channel, touchscreen guitar effects processor built around the Daisy Seed. Ten effect blocks can run in combination, with compact physical control and two update paths.

Analog audio / Three-device series

Analog Guitar Pedals

Three complete analog effects builds: a high-gain preamp, four-stage OTA phaser/vibrato, and transistor-based sawtooth tremolo.

The device is not finished when the circuit works. It is finished when the whole instrument works.

This portfolio documents complete systems: electronics, code, control logic, mechanical constraints, visual design, assembly, and practical use.
