PlasmoBaro Steampunk Barometer

This is PlasmoBaro a simple barometer with a NI-9 plasma tube from Russia. The PlasmoBaro is driven with an Arduino Nano and a step up converter to produce the 120V for the neon plasma. A high voltage single transistor driver is connected to the Arduino. The Arduino is converting the I²C Bus signal from the pressure sensor to the PWM output. The lamps indicate better forecast with the big and bad forecast with the small rivet. The scale: the big rivet is 1000mBar. Every small rivet indicates 10mBar. The range is from 1040 to 950 mBar.
