[domiflichi] is human and fallible. So he can’t be blamed for occasionally forgetting the laundry in one of the machines and coming back to a less than stellar result. However, while fallible, he is not powerless.
What if his washer/dryer could email or text him about his laundry? It seemed simple enough. Add a vibration sensor to the side of the machine along with some brains. When the load is done it will bother him until he comes down to push the button or There Will Come Soft Rains.
He started off with an Arduino-and-ESP8226 combination and piezo sensors. The piezos had lots of shortcomings, so he switched to accelerometers and things worked much better. We really like the way he mounts them to the side of the washer dryer using the PCB’s mounting screws as angle brackets. The case is a standard project box with some snazzy orange acrylic on the front.
