This repository contains all relevant design information for the SJS-ONE. The SJS-ONE is a digital software synthersizer with a dual analog filter designed as a shield for the Arduino Uno. The name comes from the fact that it was designed during the SyltJam 2011 event at STPLN. SyltJam is an annual LAN-party like weekend event for synth-geeks in Malmö, Sweden. The original DIY version is described at http://wiki.forskningsavd.se/SyltJamSynth Source code for the DIY version can be found in the ./diy/ folder. All other files relate to the commercial version, and these include: ./pcb/ Schematic and PCB (DipTrace format) + production files ./doc/ Documentation and manual ./case/ Corel Draw 12 case design (for laser cutting) ./arduino-library/ API for the Arduino IDE ./arduino-sketches/ Firmware source (SyltCode/SyltWare) ./arduino-experiments/ Experimental firmware source
