-experiment with the Smooting CAP, i already implimented ​Jumper which add second ​ Capacitor to "​double"​ the capacity... i took 220+220nFbut maybe it is better ​to use 100+220nF?\\ +frontplate\\ 
-experiment with the Frequency Pot which is a lin10K + 2K Serial Resistor which gives a range of 2K-12K - really dont know what value spectrum we need here!\\ +Debugging First Version\\ 
-adding ​some Jumpers to break the circuit for debugging or measurement\\ +**experiment with the Smooting CAP:** Header is connected paralell to integrated 100nF Capconnect there a CAP to encrease the smoothing\\ 
-frontplate, Debugging First Version\\ +**experiment with the Frequency Pot:** a lin10K + 1K internal ​Serial Resistor which gives a range of 1K-12K - i also made a Header ​here, which you can bridge then you have 1-12K, or you put a resistor there for example a 5K, then you will get a range from 6-16K... ​\\
