Lego Duplo camera holder brick

This is a brick for holding an action camera on lego duplo train. I use Xiaomi YI, but you can choose another.

It can be used for remote control and monitoring. Imagine yourself in the place of the train driver!

Another application is a _video recording_. You can use it as a simply, cheap camera slider!
also you can mount rails in circle and get panorama or impressive 3d-view of some object!
