So after banging my head on the bench for a few days whilst waiting for some bits and pieces to arrive I was browsing the Web for a project to keep me busy and came across Dave Bodnar's video on You Tube for a 'Wireless controlled hand set' for DCC++. If you are interested in Model Railway Electronics his pages are always worth a visit. http://trainelectronics.com/articles.htm This is a DCC++ controller that will run up to 4 engines (so far) selectable and programable on a key pad with Function control (lights, sound etc...). the article is here: http://trainelectronics.com/DCC_Arduino/DCC++/Throttle/#Wireless_Option and the You Tube video is here: He has used an Arduino Pro Mini and I used an Arduino Nano. Here are a few pics of the build and I will put up a short video of it in operation if anyone is interested.
