This little box is designed to add a noise source to your synthesizer setup. You only need an external audio input and a 5V source at the ring of a 1/4 stereo jack cable!
Initially this circuit has been developed as an expansion for products Little Phatty and Minitaur but it works also with other synths. The Hirlostek V2 needs to be provided with a 5V voltage, for instance at the tip of a cable. A circuit inside the box generates a bright digital noise you can use as an audio or modulation source. A 3.5mm jack version is also available HERE
