No blog post or pictures but I have taped an ADXL345(accelerometer) on the back of my washing + dryer and I'm using a pi to notify me when a load is done.

Didn't have the time to put a fancy algorithm to detect movement so it's rough, but it has been working perfectly for the past 4 years with no false positive/negative.

Why not detect current in the power cable? Or tap into an indicator light or relay? Way easier.
Absolutely, however I already had the accelerometer in hand for another project.
