SUF posted a cheap frequency counter based on MSP430 in the project log forum.

Here is the properties of the project:
– Cheap: The component total should be below $5
– Using TI’s MSP430 line of MCUs what I’m learning now
– Able to measure till 10MHz
– Using LED display
– Able to calibrate – achieve maximum +-10Hz error at 10MHz
