IN-9 build 5 + case

Posted on 16 Jan 2012 05:38

ADC input now biased with simple voltage divider and blocking cap. Case doesn't quite close properly, but I have some new, shorter, more closely spec'ed capacitors coming that should fix that. Or, you know, I could put it on a circuit board.

IN-9 neon bargraph experiment #4: ADC abuse

Posted on 03 Jan 2012 03:32

Add one resistor, one capacitor, one RCA jack, and 200 bytes of firmware to previous blinkenlight demonstration and voilà! The thing I really like about these tubes is that they are so obviously a plasma. You look at them and your mind just registers "electric flame."

Next up: properly connecting the audio input to the ADC
