The Randall Museum in San Francisco hosts a large HO-scale model railroad. Created by the Golden Gate Model Railroad Club starting in 1961, the layout was donated to the Museum in 2015. Since then I have started automatizing trains running on the layout. I am also the model railroad maintainer. This blog describes various updates on the Randall Museum Model Railroad and I maintain a separate tech blog for all my electronics & software not directly related to Randall.
2025-12-13 - Live Camera Car at Randall
Category RandallToday was the very active Winter Holiday Craft Day at the Randall Museum. This is a large event that always has a lot of crowds attending. In the train exhibit, we had a good variety of trains running, and I brought along my latest project, a live camera car:
This is composed of a Raspberry Pi Zero 2W and a Raspberry Pi camera. It broadcasts a video stream over wifi, which I then display on a tablet using my TCM Android software:
Here’s a closer look at the camera car:
More details on the build can be found here on the project page on the electronics blog.
