We all know those soldering workshops, but what if it was possible to learn surface mounted PCBs in under an hour? In this workshop, experienced workshop lecturers will help participants make a wearable, pen sized EMF-detector using real PCB assembly techniques. We will use solder paste, stencils, a few components, and a hot plate to make all the parts weld together. The workshop is great for beginners and everybody that hasn't yet got to try soldering with SMT, and might be surprised to see how easy it can be done. As a finished gadget, the EMF detector is small enough to hang around the neck, and has a flashing, 5-led indicator for visuals. It can react to anything from a touch screen to hidden power cables, electricity poles, lamps, and everything else radiating alternating current.
