Further integration for my npSynth, the raspberrypi is now talking to the arduino which sends out PWM signals smoothed (or smothered;) to DC to the analog modules. I also found out that the 7805 regulator i use to convert the 12v input to 5v to power the PI is VERY inefficient and gets very hot for even the 500mA needed. I already found a more efficient switching regulator which i will use: https://www.recom-power.com/pdf/Innoline/R-78xx-1.0.pdf. The synth is an entry in the hackaday contest: https://hackaday.io/project/160780-8-channel-surround-sound-synth-with-analog-filters As a shameless plug i had one of our IoT loggers equipped with a KType probe so i could monitor the regulator temperature: http://www.databuddylogger.com/
