There have been some misconceptions of the component markings on my circuits. Here are few examples of component markings with short description:

2K2         2.2 kilo-ohm resistor
2.2K        2.2 kilo-ohm resistor
22R         22 ohm resistor
1M          1 megaohm resistor
1 uF        1 microfarad capacitor
1 nF        1 nanofarad capacitor
1n5         1.5 nanofarad capacitor
.1 uF       0.1 microfarad capacitor (=100 nF)
