This is custom version of DIY MFOS project called "Echo Rockit". It's a portable synthesizer / effect. For more info about MFOS projects please visit: http://www.musicfromouterspace.com/
In relation to original project I made few changes:
- 6F22 battery replaced with 6x AA - longer battery life,
- added 1,5W amplifier with 45 mm Visaton speaker,
- redesigned PCB (80 x 55 mm),
- custom enclosure form pine wood and aluminum front panel,
- few changes in circuit (few linear pots replaced with audio, changed resistor values, better quality caps).
