| - | That noise board is based on a design by [[http://www.gaudi.ch/GaudiLabs/?page_id=50|Urs Gaudenz]] from Gaudi Labs and from the [[https://www.mechatronicart.ch/|Schweizer Gesellschaft Für Mechatronische Kunst]] - thanks for that!\\ | ||
| - | I added the voltage control and some extra functions, like the noise on/off the boost and the mute function to the circuit. | ||
| - | The core of the board is the digital delay chip [[http://www.princeton.com.tw/Portals/0/Product/PT2399_1.pdf|PT2399]]. It has some OpAmps build in to filter the sound and do the echo. In this application everything that helps to get rid of the noise of the chip itself was avoided, that leads into a self sustainible noise source.\\ | + | The core of that noise board is the digital delay chip [[http://www.princeton.com.tw/Portals/0/Product/PT2399_1.pdf|PT2399]].

| The "echo" could be changed with a potentiometer, the "delay" with CV (0 to 5V) or with a potentiometer. An other Low Pass filter could be changed with the third potentiometer.\\ | The "echo" could be changed with a potentiometer, the "delay" with CV (0 to 5V) or with a potentiometer.
