Well, maybe not that far off for T gauge (as standard gauge). Have a look at my thread Wireless Control for T Gauge:- viewtopic.php?f=10&t=410 and get in league with Kupzinger. Infrared (IR) receivers are smaller than radio receivers. If I succede with getting my use of T gauge radio controlled I think I will have a look at IR because even in O gauge the use of such micro electronics will be of use to me.
The guy at DT (or Deltang) supplies these products in his spare time and does not have much time to answer the intricate questions I have. Another guy sells his products:- http://www.micronradiocontrol.co.uk/index.html and he is more ameanable to questions. When I know exactly what I want and what to ask I will ask him. You may get on fine with Mr DT himself if you are much more understanding of the products then me.
I think I understand what you saying about the oscilliscope reading. If it wasn't for the back EMF the reading would go down to zero between pulses. Finding a Lithium battery to fit T gauge might be difficult. The smallest LiPos I think are produced in China but still don't know if they would fit. It might be possble to get about 2 hours running with two button hearing aid batteries.
