Extendable ATtiny85 synthesizer as the basis for a mini-modular setup.
The ATBase is the "next level" ATtiny Punk Console with an extended frequency spectrum into the bass range. Three red 3.5 mm jack sockets replace the body contacts. These can now be used to manipulate the parameters of the firs...

Midi to CV (control voltage) and clock signal converter. Receive 5 octaves over 5 volts in 0.83V steps, with MIDI note input from #24 (C0) to #84 (C5). A 5V signal corresponding to Note On / Note Off is output at the gate output.
The clock signals can be divided with the potentiometer and reset by...
10-Voices drone oscillator with optional noise mode will make you float.
With its 10 oscillators, the Levitation OSC produces spherical sounds and beats down to the very deepest sub-basses. Sine and sawtooth are available as waveforms in a wide frequency range. In addition to additive synthesis,...

Monophonic 5V Control Voltage Keyboard. The ATKeys module generates 5 octaves as a CV signal with 0-5V = 1V per octave. Two octaves can be selected via the octave potentiometer and are available over 24 keys. When a button is pressed, a gate signal is sent to the output. This can be switched to a co...

My design for the lovely Motörbörd bird call generator. Generate the required energy with the rotation of the motor.
The Motörbörd is an idea of Christoph Haberer aka ChrisMicro. The 4069 circuit version is a development of Uwe Schüler. GitHub documentation: https://github.com/ChrisMicro/Motoerboe...
Maybe the smallest LFO (Low Frequency Generator) and envelope generator module (ADSR) in one. 68mm x 45mm, 5V-level. Powered by ATBase or to use standalone with USB to stereo mini jack adapter.
The LFO/EG can be operated as a 5 volt low frequency oscillator or envelope generator. You can set the mo...
Theremin-like instrument controlled by light with 2 voices and some special chaos & sound effects. A perfect kit for soldering beginners. Functions: Blend from sine to square wave generator or switch to chaos arpeggiator mode. Output via speaker and 3.5mm jack socket.
Sound example (external Yo...
