Instrumentation and control upgrades! 2 new digital counters, a more sensitive He3 tube/trigger, and power supply remote control (enabling holding a set grid current). Also whipped up a JavaFX app with a corresponding Arduino program.
Side bar, Arduino’s Wire (I2C) library is a mess. I started work on a replacement wire lib that operates on a user-provided buffer. I haven’t gotten around to tackling a replacement for AVR which turned out to be even more of a mess, so SAM support only for the time being.
