At today's West of Scotland Area Group meeting, we were treated to a presentation and demonstration by Chris Cosgrove from the East of Scotland Area Group. Their layout is a basic oval with two additional loop sidings. A further siding leads to a turntable off which is a track to an engine shed. To add interest, a working level crossing with flashing lights will be added. The layout is controlled using an EzyBus controller, one input board and two output boards all connected by I2C. The level crossing is triggered by two laser TOTI's (one each side). To create the necessary delays, Chris designed a circuit using the PIC 12F675, the outputs of which are fed to the EzyBus Input Board. Switches are also connected to the Input Board for point selection, Engine shed door operation and turntable position selection. The Output boards are used for Servo Control of the points, the automation of the Engine Shed doors and for the level crossing gates. Additional digital outputs control t...
