Check out these tubes, pretty bad ass, don’t you think? With the help of Daniel Naito’s amazing project and the TI TLC5628CN 8-bit serial DAC I’ve managed to get my Arduino controlling an IN-13 tube. I’ve got simple 3 wire serial communication working with the TLC5628 (thanks Ogi Lumen), and but I’m only utilizing one DAC right now. The nixie tubes on the left are facing up and therefore are hard to see, but they are cycling 0-9-0.
