Household appliances become less mysterious when you take them apart. In older consumer electronics gadgets, you can often find a treasure trove of wiring harnesses that make the component connections easier to decipher. The Disco Age was also the Golden Age of Wires. A 1970s Trinitron or VCR harbors an inner beauty. Modern multi-layer PCBs and highly integrated circuits are a black box of their own. The common VCR or an old hard drive is a wonderful starting point as they are full of electro-mechanical devices and actuators.
