⚡ Soldering Included
What You'll Build
- A playable synthesizer with oscillator, filter & amp
- Arduino-powered waveform generator (sine, square, saw)
- Analog RC low-pass filter with variable cutoff knob
- LM386 audio amplifier driving a real speaker
- 8-button keyboard for playing melodies
- Step sequencer with LED position display
- Soldered onto a custom PCB in a laser-cut case
Week by Week
1
Sound, Waves & First Tone
Waveform lab, Arduino tone generator, 555-timer oscillator. Hear electronics sing.
2
Filters & Amplifiers
Build an RC filter, wire an LM386 amp. Shape your sound with three knobs.
3
Keyboard & Sequencer
8-button keyboard, step sequencer with LEDs, tempo control. Compose a pattern.
4
Solder, Enclose & Perform
Permanent PCB build. Mount in enclosure. Perform your composition live.
Take Home a Real Instrument
A soldered, enclosed synthesizer you designed and built — with three control knobs, an 8-key keyboard, a step sequencer, and a speaker.
