Nixie Bargraph Kit

Robin @ kickstarter.com launched his new campaign on a project using IN-9 Nixie tubes. Now you can easily control two IN-9 Nixie bargraph tubes with 2 PWM inputs from your Arduino, Raspberry or other control board. The tubes are controlled by PWM signals and adjusting the PWM duty cycle you can control the tubes height, thay easy!

I had the idea for this project after building myself a Nixie bargraph clock which looked fantastic and eye catching. Instead of using conventional nixie tubes, which use numbers to display the time, the time is indicated by the height of the neon glow. But, this isn’t just limited to displaying the time, anything can be indicated with these tubes,┬átemperature, humidity, atmospheric pressure, proximity… anything!
