Above is a Rube Goldberg device constructed by ulysses and cinus. The device is fairly simple as there are only 5 events involved in switching on the coffee maker.
A weight slides from atop the string, triggers a mouse trap, which then tugs another string allowing a battery to fall downwards into another mouse trap, closing a circuit.
The coffee makers momentary switch was removed from the PCB and instead replaced with two wires connected to the mouse trap. Once the mouse trap is triggered, the switch closes and turns on the coffee maker.
