Weird way of testing multiple things with Arduino

If you are nerdy enough, then such devices would look great in your collection. Ctopconsult have build so called Arduino monitor/tester. It has a monster load of LED indicators and other things that enables to test and control multiple things from a single board. There is a long list of supported sensors and devices. Each input and output has a LED indicator. It is Arduino compatible as a shield and can be powered from either 5V or 3.3V. As separate attachable module there also comes LEMO I/O, shake sensor, TMP36, microphone, piezo speaker. Built in options include button, toggle switch, two pots, seven segment display, small coil voltmeter, piezo speaker, 4 digital outputs to open-drain MOSFETs, couple opto-isolated I/Os, couple I/Os through LEMO coax-connector, reed relay, mercury shake to digital input, LDR, NTC, etc. Once front panel is one, everything seems pretty well organized and obvious with its text labels and numbers.
