Triumph!

Rather unbelievable, but with the pressure solenoid dialed in properly, the suit is now holding appropriate pressure, indefinitely. That is, the solenoid has knocked out the leak rate, with only a very small use of pressurization gas. It's a bit of a cheat--I still need to seal a leak in the boots--but the principle is well-established, now. In case of leak at altitude, the solenoid kicks in and maintains exactly the pressure I establish with one control knob. The tangle of hoses and wires, of course, is just here during development, and will be completely squared away in the final build. Hoo-ah! Triumph!
