 ===== To Do =====
-experiment with the Smooting CAP, i already implimented a Jumper which add a second  Capacitor to "double" the capacity... i took 220+220nF, but 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:** a Header is connected paralell to a integrated 100nF Cap, connect 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... \\
