I'm just using the ADC that's built into the Nucleo F401RE. It has 12-bit resolution, and is fast enough for my purposes.



As below, so above.

The ADC is fine.

Just make sure the signals are free of external/internal noise by using earthed screening tin (soup can), filtering capacitors and maybe even ferrite beads in the signal path for hi-freq noise.

Is it ready yet ? C'mon !

This part holds the laser, the 40x objective lens (cannibalized from a microscope), and the beamsplitter (which hasn't arrived yet).
