So for anyone out there wondering what these would look like mounted in the project boxes mentioned above, here is a pic and a video of the first test hooked up to all 4 ports of my bench TIU; just showing the watchdog signal. Next step; putting it on the layout. These project boxes are nice and small and nicely accomodate two test boards. The setup below has the two variable ports at the top of the box, and the two fixed ports at about the mid-point. They fit really well.
Sorry the darn pic got rotated 90 deg CW. The wires come out the top. I wish there was some way in OGR to rotate a pic to the correct orientation for when this sort of thing happens!
