This is a challenge for creating a mechanism that toggles an LED every time an NO push button is pressed and released. The circuit must contain one DC voltage source, one LED that will be the output, one NO push button that will be the input, any number of BJTs (NPN and PNP), and any number of resistors (any value). Nothing else, like capacitors or relays. The number of points a circuit scores is the number of BJTs it contains. The circuit with the fewest points wins (like in golf, the person who scores the fewest points is the winner because they had to hit the ball the fewest times). This circuit scored 17 points. Can anyone get a better score than me?
Current winner: @hurz at 5 points. Link: http://everycircuit.com/circuit/5709202692767744
