Hello, I am currently working on a theremin project. This one exactly: http://interface.khm.de/index.php/lab/interfaces-advanced/theremin-as-a-capacitive-sensing-device/ There is a schematic and breadbaord diagram if you scrolld down. The author has also mentioned this: "Care must be taken in the choice of the parts L1 and C1. C1 must be a ceramic capacitor NP0 type (zero temperature coefficient) and L1 a high Q inductor suitable for high frequency such as a Neosid 00612299 but for the first test a standard 10uH Choke will do also the job." I ordered this item: http://www.mouser.com/ProductDetail/Kemet/SU16VD-40010/?qs=%2fha2pyFaduioQQvSwxPrBQYRxCMxaM8Q4eXENqjGH0g%3d Datasheet: http://www.mouser.com/ds/2/212/KEM_LF0021_SU16VD-417258.pdf So my first question is this, will this inductor be applicable for this circuit. Can it work. The datasheet doesn't help me much. My second question is, how the heck do i put this on a breadboard. It has 4 pins and im not completely sure how it works. Any help will be appreciated.
