/* Connection Caution */
Aside from the components on the PCB, one does also need a transformator, which isn't shown on the photos. Despite of being a very important component, the DIY article contained only few side-notes on the transformator. The thing must provide a number of AC voltages, and it might be difficult to find a matching transformator (one could get one from the magazine via mail-order, but it wasn't cheap).
