Was thinking about ordering/assembling a few of these. http://www.paulswan.me/arcade/ArduinoMegaICT.htm Only thing stopping me is that it's not clear if I need a Fluke Probe cable or what.
Doesn't look like it - there is a second fixed version (V1.01) of the probe head board further down the page, so you would just need both the PCBs and some twisted pair ribbon cable.
