I’ve taken an old airplane radio and hacked it down to train size. Channel 1 is now a pot for speed and the two push buttons alternate a servo ‘position’ on channel 2. Not enough I know but this is just a quick prototype.

The tray has my Android tablet where I’m running an html5 page talking to a tornado instance on the server. The page takes finger presses and sends them via tornado back to the server. It turns them into servo movements out ‘in the field’ via Wixel wireless and Python to change the turnouts. Whew. Long path there but it works quite well.
