Some folks on this list might get it from a Yahoo account.

CentOS Linux 7 (1611) released for Raspberry Pi 3
and Raspberry Pi 2, Banana Pi, CubieTruck, and Cubieboard SBCs.
Unfortunately, it seems to have only a 32-bit kernel,
so it take not take full advantage of the 64-bit CPU in the RPi3.

Re lm139a.pdf from ti for LM339N

    compare following from section 8.3 on page 10:

        The output NPN sinks current when the positive input
        voltage is higher than the negative input voltage and the
        offset voltage.

    with following from section 9.2.2.1 on page 12:

        If IN– is lower than IN+ and the offset voltage, the
        output is high impedance and the output transistor is not
        conducting

So a pebble watch will become about as useful as a pebble.

The notes and code for the 2016-12-20 meeting and debouncing presentation
will be posted eventually.

In the mean time, peruse the following non-linear real-world behavior.
