This is the third instalment in my attempt to make a home-made DCC locomotive decoder - in this one I shrink what I've done so far into something that will actually fit into my Voyagers, and take a detailed look at how to control power to the Voyager's lights through the printed circuit board that's part of the model.
I haven't duplicated much of what I said in the previous videos, so if you don't know how DCC train control or ATtiny85 microcontrollers work, it might be worth watching the earlier ones first:

In this video I mentioned it was difficult to find connector pins of the right pitch and diameter - here are links to the ones that I bought - both fit the Voyager's 6-pin socket.
