2N7000 R_DS on

For the 2N7000:

R_DS = 2.3 Ohm  V_GS=3.3V
R_DS = 1.6 Ohm  V_GS=5V

So at least at 3V3 it's more than an order of magnitude better than
the PIC output drivers.  RC time is (* 2.3 0.45) 1uS.  I guess that's
good enough.  Let's try a couple more to see the variability.

6.3
4.1
6.3
2.3

Looks like the first one was a good one.
