When I started to make electronic things I knew almost nothing about how they work, but with simple solutions I managed to make usable instruments anyway. For instance I used a speaker as a relay, where a transistor should have been used. Because of knowing little I used my creativity in a none efficient way, I invented things that already existed. But I feel proud of these inventions, for instance the Relay, the Vactrol and the Phase Locked Loop. Nowadays I know much more about electronics, but I still want to work the same way as when I started.
