This pcb design project is based on Peter Knight's Arduino Nano Synth code and Notes and Volts Line Output upgrade. 

You can find all components needed in Schematic and .xls file. It has 2 option to power the device. 

All components are DIP type of component. Please use ceramik type 33 nF capasitor.

The circuit can be power up by directly arduino usb socket or power adaptor socket by using a 9v adaptor. 

Please pay attention if your adaptors pinout should be right this; TIP : (-), SLEVE: (+). 

And do not plug the adaptor and usb power at the say time. That might burn some components on arduino nano. 

Pay attention to solder all components even arduino exception potentiometers to bottom side. Only 5 potentiometers should be soldered to top side of pcb. If you solder other components to top side, that might make difficult to housing the circuit. Just see the rectengular borders for each component to see which side of pcb you should solder.

Thanks to Notes&Volts for easy tutorial videos about this project.
