Foam cutting help
One thing I forgot to mention... Don't make your line/hole layout without having the parts to compare them to. The original design layout didn't match the size between holes for a few of the components for me. The triac is one that I remember being off between where the connections are on the component and the instruction guide for the curcuit board. If you do a block diagram board like the instructions say, all you have to do is move your holes. But if you do a line diagram board then you need to place your holes first and connect the lines as required secondly.
