After 4 decades of IT work, I’ve retired and now focus on hobbies and generally taking it easy. My interests (and the focus of this blog) include 3D printing, CAD, Raspberry Pi, and Python with a little machine learning thrown in for fun. Most of my projects are model train related.

My modeling attention is focused on the Gilpin Tramway – a unique 2 foot gauge mining railroad that was built in 1887 to serve the gold mines in Gilpin County CO.
I have several goals for my blog. In general, my hope is to provide some bits of knowledge that might help other makers. More specifically, I want to encourage other modelers to look at the Gilpin as a worthy prototype for modeling.
