IoTT's video: Amp Meter for DCC EX - It works Video 104

In the last video I discussed some of the difficulties that come with measuring the current of a DCC signal and why an occasional readout of the DCC EX current values does not do the trick. Today I show you how I implemented current gauges for main and prog track of DCC EX that work surprisingly well.
