Has anyone tried building a working theatre style route indicator using small LED dot matrix devices? If so what did you use and from where? I have found some that are 12 x 17mm but I feel they are a little large for 4mm scale. I know one company produces working ones custom built, but having difficulty in my wife letting me spend that amount!!!!
