Here’s the latest Gadget Freak from Design News that shows you how to build your own lighting control unit for model train sets – “Looking to light up the town, model railroad enthusiast William Grill developed this unique and flexible control board for driving lighting for water towers, running and crossing lights, and storefront dress-up lights. The microcontroller-based application enables the selection of four display formats using five outputs, including combinations of sequenced, bouncing, and dual beacon displays. Since the architecture is table-based, the design allows the possibility of simple redefining and customizing with longer display sequences. And powered from 7 to 18V ac/dc, the circuit uses only a few milli-amps of power.” – Link.
