A voltage detector

A simple voltage detector using a 1nF Capacitor as an antena - that way you won't need to touch the component to identify the electrical field. It will make the LED light up when it detects the current. I'm a beginner at this so feel free to point out mistakes and make improvements!

@giomix every transistor should do the work like 2n2222 or 2n3904 and all the others
