I designed this train as a simple and comparatively inexpensive version for the OS Railway System. The goal was to build a robust train with parts that are as easy to obtain as possible. The train uses an inexpensive geared motor and is controlled by an ESP 32 controller. You should have basic electronic knowledge and be able to solder for the construction. Additionally, you should be able to upload a program to the controller via Arduino IDE.

You need to config the ESP_32_ESPNOW_Sender program with your controller MAC adress. Use the ESP_32_ESPNOW_Adresse programm to get the adress. You can find a tutorial on

You can find an assembly video on YouTube:

 

!! If You have Problems with the direction or function, try to use out 1 and out 2 or switch + and -.

The following parts are required for the construction:

  • 2x ESP 32
  • 1x L298N Motor Controller
  • 1x Potentiometer
  • 2x Switch
  • 2x Push Button
  • 2x 9V Battery Cable
  • Wires
  • 2x M3x 40 Threaded Rod
  • 2x M3x 30 Cylinder Screw
  • 4x baering 3x6x2,5
  • Nuts, M3, M5
  • Rubber Bands

You can find the most parts at your local hardwarestore, also here are a few links to the parts on Amazon
