HP5508A interferometer display replacement
Lets create a replacement for the HP5508A interferometer display.
Helium-Neon Laser based interferometers are fun to play with, and the appropriate lasers come up relatively cheaply on ebay from time to time. However, the necessary display is quite a rare find, and when you do find it, it is pricey.
So I wanted to make a microcontroller based replacement. And here you can find a list of the pages related to this effort:
