Fidget Spinner Synthesizer – Limited Edition

Description

This is a functional prototype built from 8 rescued fidget spinners. Quirky, imperfect, but absolutely one of a kind.

👉 You can see it in action in the video (demo starts at 13:10 for MIDI and 15:38 for features).

The main mode is an arpeggiator, with adjustable:

• Tempo (60–180 BPM)

• Division (1/4, 1/8, 1/16, 1/32)

• Pitch & Scale (Ionian, Dorian, Phrygian, Lydian, Mixolydian, Aeolian, Locrian)

Sound sources: SINE, TRIANGLE, SAW, SQUARE, BAMBOO sample
Built-in effects: Filter, Warp, Tremolo, Glitch
Includes full source code so you can modify it yourself.

Connectivity: headphone output, built-in speaker with amplifier, works with a power bank.

Important to know

• Limited edition: only 5 units ever built, each one signed by me.

• This is not a polished product, but an experimental art piece.

• The IR sensors are disrupted by infrared and sunlight. Normal daylight usually works fine, but on sunny days (even indoors) the instrument will not function properly.

• The amplifier crackles and the volume knob can only be opened partway – otherwise the synth restarts.
