Cardiologist Retirement Clock
What else could I use when I was asked to make a leaving present for a retiring Cardiologist, other than a vintage ECG machine?
The orignal machine was cut down in depth considerably so it could be mounted on a wall, or stood on a shelf. A 4 tube Nixie Clock was installed where the original screen went - and the dial for the heartrate was then repurposed so it now shows seconds.
Really interesing project, and probably the only ECG Nixie clock on the planet!
