I only used 470 microfarad for the last cap. Then with 11 volt the motor has problem starting. Adding 1000 mF and raising the voltage will make it start immediately. Maybe it needs more '' energy '' to start up.
The LM317 is famous for creating high frequency noise so dont wanna use it.
I know about colour codes but this is just for a little test. When i send it to my friend he will use another transformer.
