Frequency Counter - 6 - slightly faster than older versions

The frequency being measured is the AC voltage source in the bottom left corner. This is counted against the reference frequency adjacent to it.
Only 10 Hz resolution & 0 - 990 Hz.
Have to wait a while for the pulse to complete from the reference frequency :(
On this version, used two op amps to double the input  frequency. These are set up to with a narrow pulse width to give separation between the pulses. Reference frequency also doubled. This gives a slightly faster time to measure the frequency.

How did the connections without the wires?

When a circuit gets too crowded, there is not enough space to show the routing of the wires, so Every Circuit just puts a coloured dot on the connections. If you see three blue dots, then all three are connected. Every Circuit does this automatically.
