KOSMOS Function Generator
About the KOSMOS Function Generator PCB
KOSMOS Function Generator is an open source PCB design by DavesKosmoModules, published on GitHub under the CC0-1.0 license. It is a 2-layer board measuring 96 × 125.6 mm, with 96 components from 29 distinct parts.
Other key parts include the TL074, AS3310 and TL072. By type, the board carries 48 resistors, 13 diodes, 13 capacitors, 5 ICs, 3 switches and 2 transistors.
From the project
- Envelope generator switchable between ADSR & AD - Loopable - End Of Cycle output - Output can be inverted for ducking
- Envelope generator switchable between ADSR & AD - Loopable - End Of Cycle output - Output can be inverted for ducking
- When in AD mode use the trigger input - When in ADSR mode, use the gate input to start envelope, the trigger input will retigger the attach phase - When in cycle mode use no inputs
Contained are schematics & gerber files for pcb fabrication of both electrical and front panel. This is sutiable for entry level however a basic level of electronics, soldering, fault finding, and some basic tools are required.
