Simple capacitance meter

[Mike] sent in a project he’s been working on lately. This little circuit can measure the capacitance of a capacitor by generating a frequency that’s inversely related to the capacitance. He originally got it working with his o-scope, and followed up by building a stand alone version that uses an ATTiny2313 and a text LCD.
