Radiant Dice

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

I completed the front panel today. 

1. Laser cut 3mm white acrylic for the front and back layers of the panel
2. Attached the panels together (IPS Weld-On 3 Acrylic Plastic Cement)
3. Spray Painted them with a Matt Dark Green from  Rust-o-lium
4. Taped down and cut a piece of cardstock for alignment, and burned away the paint leaving the white behind
5. I then mounted everything.

Up next:

• Test/code the indicator lamps below the knobs
• Design and 3D print a frame to hold the lamps, marble and UVLEDs
• Cut the base piece which holds the power supplies and Geiger counter

Received and partially populated the circuit board. I wanted to test as I went since this is my first circuit board., and my first high voltage project. As I added components and test, everything seemed to be working without issue.

On the code side, I updated the code to incorporate the Nixie Tester drivers, and the external OLED.
