As a bit of a computer nerd, I've combined my hobby with some IT

I run a SPROG 3, connected to a Raspberry Pi. The Pi has a Petrockblog PowerBlock to manage on/off switching, and a small 7" touch screen) although most of the time the Pi lives sight unseen under the board. The layout is powered by pushing a simple on/off (SPST) latching switch, which powers up the Pi. After a couple of minutes the Pi is booted, and JMRI is running, auto-booting its web server. Running Digitrains app on my Android phone, I can then make the trains go.

At the end of the session, turn the switch off, and the PowerBlock sends a graceful shutdown command to the Pi, which powers off.

A pair of Cobalt Digital motors drive the crossover pair of points, coded to the same address - also controllable from Digitrains.
