   Means we need multiple header pins carrying pyro voltage to get enough
   current, since the header spec is 3A per pin.  2-4 pins each for v_pyro
   on the pin 1 end, and gnd on the other end should do.

+- for strand burner daughter, use CUI TB003-500-P06BE 6-position 5mm pitch
+  screw terminal strip, supports 14-26 AWG wire, 10A per pin continuous,

+- thinking about connectoring again.  for the base TeleStatic, we need to
+  have DC power in for battery charging, pyro output, pressure sensor, and 
+  load cell.
+
+  For battery charging, use the same powerpole and 3d-printed part we use on
+  TeleFireEight.
+
+  For pyro output, let's try a panel-mount single 3-wire AC socket:
+
+        Schurter 4300.0701, DK 486-1082-ND, $1.48 q1, needs a complex routed
+        opening, has lugs for soldering wires.  Sides squeeze to remove if
+        if needs to be replaced.  Should be easy enough to CNC mill opening.
+
+  For the pressure sensor, a 3-conductor 1/4" audio plug seems like a great
+  plan, use metal-shell Switchcraft parts.  Couple that with shielded twisted
+  pair cable.
+
+  For the load cell, we need 4 conductors plus ground, so a 5-pin XLR is an
+  economical possibility.

+
+  Gary's load cells use Amphenol PC04E-10-6P, which is $64/ea from Newark!
+  Could offer to deliver him a cable with one of those on one end and what
+  we want on our end?
+
+  Cable that's 2 twisted pairs, shielded with drain wire, would suffice for
+  the load cell and could be used ignoring one pair for the pressure sensor
+  if desired.  Here's one with grey PVC jacket and foil shield:
