Oskitone's Scout Synthesizer Sounds as Cute as It Looks

"Thanks again to Tommy for sending me this adorable synth. You can find the Scout—as well as his other musical creations—at https://www.oskitone.com/ or on Twitter at @oskitone"

New from the makers of the POLY555 Synth.

It's called the "Scout" because it's the first Oskitone synth to use a microcontroller, specifically the ATmega328 -- just like the Arduino Uno.

From the readme:

scout (/skout/):

One sent to obtain information
Jean Louise “Scout” Finch, of Atticus Finch
The first synth from Oskitone to venture into the big ol' world of microcontrollers
The Scout is:

Beginner-friendly: All components are through-hole (instead of surface mount) for easier soldering, and full assembly takes about 45min. Standalone, battery-powered, doesn't need a computer or external speakers to work. Fun! 3D-Printable: Besides the electronics and nuts and bolts, all parts are 3D-printed. And with a total width of ~160mm (about 6.3"), the Scout can fit on smaller, "Mini" (18x18x18cm) size print beds.

Hackable: Arduino-compatible and fully open source! Hook up an FTDI Serial TTL-232 cable (sold separately) to update its code using the Arduino IDE.

Minimally featured: 1.5 octaves of keys, a volume knob, on/off switch, speaker, headphone jack. Monophonic square wave with fixed glide and octave.

In addition to it being the first microcontroller-controlled instrument from Oskitone, the Scout would also make a fine introductory DIY instrument for the budding electronics hobbyist. (Some experience soldering and a general familiarity with how electricity works are recommended though!)

Like my previous work, I designed the Scout's PCB in Kicad and everything else in OpenSCAD, specifically for 3D-printing. The Scout is available assembled or as a DIY kit, with and without the 3D-printed parts; and it's fully Open Source!"

Satisfying "clicky" tactile switches
Built-in amplifier and speaker
Soldered, assembled, tuned, and ready to go!
Also available as a DIY Kit.

Version: A

External controls: 20 keys, volume wheel, on/off switch
Internal controls: 20 trim potentiometers for tuning notes
Dimensions: 7.6"x 6.25" x 1.5"
IC Chips: LM555, LM386
Input/output: none"

The Oskitone OKAY Analog Squarewave Synth

Oskitone OKAY 2 from oskitone on Vimeo.

http://www.oskitone.com/product/okay-2-synth

This one is in via @deejayiwan. Originally $180 on Oskitone's website, it is now available for $60 on Tindie.

Monophonic, analog, square-wave synthesizer with 2 octaves of keys and octave divider

Monophonic:
Only one note at a time can be played. This is opposed to “polyphonic,” where multiple simultaneous notes can be played.

Analog:
There are no computers, microcontrollers, sound samplers, or anything digital involved. The sound you hear is the sound of a speaker being abused by discrete electronic components like capacitors and resistors and logic chips.

Square-wave:
When its output is viewed on an oscilloscope, its wave resembles a square. It’s a “hard” sounding wave type, great for bass lines, and commonly associated with chiptune music and old video games.

This is the OKAY 2 Synth DIY Kit, and it's just like the original OKAY Synth but now features two octaves of keys and a 1/4" audio out jack. Assembly required. Includes the PCBs, electronics components, and assembly guide.

If you have your own 3D printer, you can print the enclosure, keys, and all the other non-electronic parts yourself. 3D model STL files are available on Thingiverse.

If you want 3D-printed parts included, please note that they will be printed on demand. These orders typically ship within one business week.

Under the hood, it’s powered by an LM555 timer (astable mutlivabratory), CD4040 ripple-carry binary counter/divider (frequency divider), and an LM386 power amplifier. All are the standard circuits you'll see diagrammed in their datasheets.

Monophonic with high note priority
Six selectable octaves and one octave of keys
Satisfying "clicky" tactile switches
Built-in amplifier and speaker
9v battery required, not included"
