Needing to chip a locomotive, I stuck a note on a forum asking for recommendations. Since I know little of the world of in-chuffer electronics, it seemed the sensible thing to do.
A suitable device was suggested and I place an order. £13 still hurts when you are a skinflint, but this is the future I am told so I better get used to it.
Which makes it super anoying that the thing won't plug in. Wrong pins it seems. So I'll have to go and buy another. I'm sure many of you will be smugly laughing at me. I'll learn to check more closely in future but at the moment I'm much more a gods own DC fan!
