The wins:

• Indicators under each knob are working. I added a length of wire to each one, and put heat shrink over the joint. They went to the screw terminals, and it was pretty fast and easy. The indicators are a pretty tight fit, so I don't think I'm going to need to add in a 3D printed clamp for them.
• The Bound/Rolled switch is wired and working. I had already coded this so it was just a matter of making sure that the direction was correct.
• I swapped in the IN-15A symbol tube for the number tube.
• Backpanel is cut and installed. I made a panel for the 5v/12v power supply, the high voltage nixie supply and the Geiger counter. I attached it tot he back of the case with Velcro strips. I had considered drilling holes and mounting it to floor, but this seemed simplest.
• I revised the software run the indicators, and fixed the symbols so they correctly display now. I also worked on the negative number glitches. If you send a negative number to the nixie driver it will shut it off.

Setbacks:

• The Engage switch came faulty, I had to get a replacement.
• Geiger Counter is dead. I mis-wired the pulse output and fried something. I misremembered the wiring and didn't look it up before testing. I'm working through that problem now.

Next Steps:

• Wire the GX16 Connector for I2C to go to the OLED
• Mount UV LEDs and Marble
• Replace Engage Switch
• Take a lot of pictures
