I've seen around the forum this subject pop up once in a while, but revisiting isn't always the *worst* of all ideas.
I'm just contemplating a 3 train coffee table layout, and for lazy automation reasons dcc seems the easiest of programming things to use.
I've seen someone glue a picaxe to the roof of a t motorised chassis but I gather from their descriptions that they generated their own signals to instruct the train and it's far from nmra compliant.
The key bit of info which leads me to try and retread the topic here is this: http://www.digitrains.co.uk/ecommerce/s ... coder.aspx
which I've not seen come up on any fora. It claims dimensions of 7.5 x 5 x 1.8mm. I don't yet posses any t-gauge rolling stock so I can't measure the insides of anything.
Does that sound like it would fit in any voids in either a motorised chassis or a trailing carriage?
I'm slightly in love with t-gauge and would be pretty sad to resort to clunky old z just to get dcc :/
Were this decoder physically able to fit into a chassis then I think the only thing to overcome is the voltage applied to the motor, I'm unsure if 10V on the rails and only using the first 64 bits of pwm speed control would protect the motor enough, or if some other voltage conversion would be needed to get it to 4.5V ish RMS.
Would anyone with experience of dcc at a larger scale have any advice for me?
