An attempt to build a digital version of John Alexander's cheap STM design!

Apologies for the lack of work over the last few months. I have been starting my PhD on microwave metrology and it has taken a lot of my time. However, I have now acquired an enclosure for the microwscope (an old 3U eurocard chassis from a vacuum controller). My plan is to have half the chassis taken up by signal conditioning and perhaps an embedded computer and display, with the rest of the chassis containing a slide-out tray with the sample stage and probe.

I am going to order the parts to make the analog version linked to on this page, get that working and then start the modifications.
