MSP430 Nixie Clock

Recommended Posts


I requested the source code about 8-9 months ago. I finally found some time to add an option for cathode poisoning prevention to trigger every 5 minutes.

The updated list of options are:

Cathode Poisoning Prevention Effects [0-3]

0. No effects

1. Slot machine (Every 1 Minute)

2. Slot machine (Every 5 Minutes)

3. Display time for 2 seconds, off for 8 seconds


I plan on trying to create a case to enclose the sides. If I come up with something I'll share it in this thread.


Thanks for creating a fun kit to build with clean code to modify.

Hi All,

I just finished assembling and modifying this kit for my SO for Christmas. I put it in a vintage toaster from 1910. Works great and so cool! However, watch out for shorting anything while the clock is powered - I fried some transistors while playing around with it.

In any case, I made quite a few modifications and will post them here. I added the following components to the kit:

Arduino UNO I had lying around.

Random photodiode I had lying around.

Adafruit RTC module: https://www.adafruit.com/product/3013

Adafruit motion sensor: https://www.adafruit.com/product/189

I modified the code to use the photodiode and motion sensor to control the brightness of the display using PWM. I have attached that. It is not written with extreme discipline, but it works :)

Let me know what you guys think,
