You Can Build and Hack This Open-Source Synthesizer

Build and Hack Your Own Open-Source Synthesizer: The Scout Monosynth

The Scout, a build-it-yourself monosynth from Oskitone based in San Francisco, offers a unique opportunity for synth enthusiasts. This easy-to-assemble instrument is available for purchase now, and the best part? It’s free and open-source, encouraging users to modify and improve its functionality.

Easy Assembly and Customization

Designed with beginners in mind, Scout utilizes through-hole components, simplifying assembly and soldering. Powered by AAA batteries, it features a built-in speaker for standalone use. Furthermore, if you own a 3D printer, you can print the case for this compact synth (160mm wide) on mini-sized print beds. Oskitone describes Scout as an excellent introductory DIY instrument for aspiring electronics hobbyists.

Features and Limitations

Scout boasts a one-and-a-half-octave keyboard, volume knob, on/off switch, speaker, and a headphone mini-jack line out. However, it intentionally lacks sound parameter controls; it produces a square wave with fixed glide and octave. This design choice reflects Oskitone’s focus on providing a simple, accessible introductory synth, rather than a feature-rich instrument. The omission of features like selectable waveforms, filters, envelopes, or MIDI/CV support is a conscious decision to prioritize ease of use for its target audience.

Modifying the Sound: Open-Source Hacking

For those keen on customization, Scout’s open-source nature allows for significant modification. Connecting it to a computer using an FTDI Serial TTL-232 cable enables code updates through the freely available Arduino IDE software. The source code is readily available on Github, opening a world of possibilities for experienced programmers and those eager to learn.

Pricing and Availability

DIY enthusiasts can purchase a Scout kit for $42. Alternatively, pre-assembled Scouts are available for £125. The device comes in Atomic Pink and yellow.
