HO Scale Track Scales / Weigh Station

This is a collection of parts to make an HO scale weigh station / train scale. I used an Arduino Nano and and Arduino Mega due to the scales library being a large memory hog. You may be able to use other Arduinos but that's what I went with. See my video on YouTube: https://youtu.be/d24vZDi6BWU -Updated 9/4/22 The Arduino Sketches and Wiring Diagrams are here: https://drive.google.com/drive/folders/1cYAL-k_ukXBNTkJ5bv23ysgVihX0h9pj?usp=share_link (Updated 2/11/2023)

These parts are what I did but I imaging others may want to do something different. You can easily scale the Z axis in your slicer for some file to get the right heights for your layout. The load cell mount is designed to allow you to level the track in all 3 dimensions.
