Basic clock designed around a IV-21 FL tube
- This project was largely mutated from sjm4306s project
- The max6921 control code was borrowed from DellaRaccoon
- the mcp3x21 code was pulled from "Andon", I do not recall where I found it.
- As always, many thanks to Adafruit for all of their contributions to circuit python
- A FL tube, a IV-21
- XIAO board. I am using a ESP32C3, but many micro controllers work
- mcp3x21 A2D converter for getting feedback of the drive voltage for the device
Find the board files Here
I made a simple case for this device in Fusion 360. All files are avaliable Here
The esp32 code can be found here
This code is still a WIP. It doesn't do more than display some numbers.
Most of the code development tims so far was just in getting the dc-2-dc circuit working correctly.
This is an image of the clock running:
