0053 Making a DCC decoder from scratch - part 3

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:    • 0047 Decoding DCC from scratch   - 0047 Decoding DCC from scratch    • 0052 Decoding DCC from scratch pt2 - ATtiny85   - 0052 Decoding DCC from scratch pt2 - ATtiny85 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. 1.27mm Pin Header, 1 Row, 6 Way: https://cpc.farnell.com/multicomp-pro... 1.27mm pin headers and sockets, various: https://www.amazon.co.uk/dp/B0DQ4CVMQF Other things I bought for this stage of the project: 8 Pins Flat IDC Rainbow Ribbon Cable 300cm 1.27mm Pitch https://www.amazon.co.uk/dp/B0CJYKMBJS DIP IC sockets, 8-pin: https://www.amazon.co.uk/dp/B0DSMZ7Q98
