I seem to always have three or four hardware projects going at once; every now and then I actually finish one. I just put up pictures and a description of the module here.
It’s a utility module that can add, subtract and scale signals. It also generates the minimum and maximum values of a pair of signals. While describing it to Chris I called it a “CV processor module thingy” which he thought was a perfect name, but that didn’t quite fit on the 1U panel.
