Retro video games sounds…for your toilet

After reading about a Super Mario Brothers themed bathroom, [Jonathan] decided that it would be pretty cool to have his toilet play the “warp pipe” sound whenever anyone flushed.

He grabbed a small sound drop key chain on eBay and disassembled it to see how things worked. Once he figured out which solder pads corresponded to the warp pipe sound he added a few wires that, when shorted, trigger the sound effect.

He debated as to how the sound generator should be wired to the toilet, and was pretty reluctant to place the key chain inside the tank due to concerns about sound volume and water damage. He ultimately decided to trigger the sound effects using triboelectric charge, much like those touch lamps from the ’80s. He rigged up a simple circuit that is connected to both the toilet handle as well as the water intake valve on the wall. When someone touches the handle, the small charge that is present in their hand triggers the sound effect as you can see in the video below.

Instead of using a standard project box, he opted to build a small warp tube replica from cardboard and paper, which really brings everything together nicely.

While he says that the circuit is pretty sensitive, triggering at odd times or not at all, we still think it’s awesome.
