Since no boards from Bluerailtrains are available anymore, I am working on a development of my own WIFI based controller. The power supply of 10x 10F capasitors (in seria for getting 1F @30volts) and the L298N motor amplfier are already installed. The NODEMCU (development board containing a ESP8266-12) is also programmed as webserver including a websocket service to control the locomotive.
So I’m on the way to implement my first webserver on rails…. 😉
