Hi All I have been following a couple of threads on this forum and I am wondering if here is a place for basic electronic tutorials. Taking things back to the very basics but in a particle way as attached to model railways. I am thinking of simple circuits and the way I would approach how to translate these to a circuit board and a working model or the railway modeller. I would be willing to take on this role if it was thought that it could be of help. I would try to break down the circuits to the basics that I understand. I have to say now that I am not an electronics engineer but have picked up bits and pieces along the modelling way. I have built several layouts some with a greater degree of electronics than others. I have also built 3D printers a 3D scanner, a CNC router, I have converted a vertical mill to CNC, and I am just converting a lathe to CNC. Now that I am retired and a widower and I have more time to devote to this great hobby and would like to pass on some of what I have learnt. I will wait to see how this post gets received before going head. I will be on holiday for the next fortnight and I was thinking if you want me to go ahead then the first circuit to explore would be coach lighting circuit that Keith M has been talking about.
