COMPONENT OVERLAY DIAGRAM ERRORS IN APRIL ISSUE Unfortunately, the component overlay diagrams for both the `38-LED Roulette Wheel' and `Digital Trigger Adaptor for Scopes' projects suffered from a printing error, where the actual component outlines did not appear. The diagrams are on page 50 and 38, respectively, and show a wash of blue over the PCB pattern instead of the component images. We apologise for any inconvenience that this has caused, and we will republish the diagrams in their correct format as soon as possible.
