The ATtiny Punk Console (ATPC) is a programmable 8-bit mini synthesizer. From Noise Toy, over Drum Sound Generator, Atari Punk Console to Drone Generator - everything is possible! Short audio sequences can be used to upload new synth programs via smartphone or PC to remap the 4 potentiometers. Own codes can be programmed via the Arduino IDE.
Further features:
• Analog output and filter section
• parallel connected 6.35 and 3.5mm jacks
• body contacts
• 5V gate in- or output (programmable)
• fused against overvoltage/ negative input
• 7-15V power supply (center = ground)
• and an audio-bootloader! That means from now on the sound and the programming of the synthesizer can be changed within seconds by playing a short audio sequence into the machine. Various codes can be downloaded, which change the function of the whole kit.

2 octaves monophonic (5Volts CV) keyboard with 5 octaves selector knob. Powered by ATBase, or to use standalone with USB to stereo mini jack adapter. With the ATKeys CV module 5 octaves can be generated as CV signal (0-5V = 1V per octave). 2 octaves can be selected via the octave potentiometer and are available on 24 keypads. At the same time a gate signal goes to the output, which can be switched to a continuous signal by the latch switch. You can either connect it directly to the ATBase via the red jack or use it standalone with a USB to mini jack adapter for any CV capable device.

Expandable ATtiny85 synthesizer, which acts as a 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 3.5mm jacks now replace the body contacts. These can be used to manipulate parameters from the outside with control voltages of 0-5V. The trick with the red marked jacks is to lead out the supply voltage and simultaneously lead back the modulation signal via a stereo cable. This allows you to test your own CV circuits (e.g. super simple with 2 components: a resistor + light sensor) or connect noisio CV modules.

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 mode by pressing the button at startup. In LFO-mode 5 waveforms are available: Square, Sine, Triangle, Ramp-Up, Ramp-Down. Furthermore, speed, modulation depth and bias (average value) can be set. As an envelope generator, the module can process the classic parameters attack, decay, sustain and release. The signal can be triggered via the gate input or the button. The LFO/EG can either be connected directly to the ATBase via the red jack or can be used standalone with any CV capable device and a USB to mini jack adapter.

2 voice theremin-like instrument controlled by light with some special chaos & sound effects. A perfect kit for soldering beginners. Functions: Blend from sine to square wave generators, chaos arpeggiator mode, output via speaker and 3.5mm jack socket. Status: v2 kit
Continue reading...Levitation Oscillator
10-Voices drone oscillator /sinus or sawtooth 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, there are optional noisio-typical 8-bit register overflows for chaotic sound calculation and a one button random chime generator. A signal to the Trigger In or pressing the corresponding button fades out the sound (ducking gate).
