I’m Popular!
Hi everyone from Makezine Blog! Very happy to see you and hear your comments.
Here’s an update on where I’m going:
- We went to University of Iowa’s surplus store and picked up several small computer microphones. The guy there suggested piezos (similar to several comments that have rolled in) as sensors, but cautioned that the different sized piezos are sensitive to different frequencies.
- I’m looking harder at doing a current clamp to detect current flow in to the washer and dryer. This would eliminate a lot of the electrical noise picked up by the microphone (but would probably pick up other kinds of noise).
- Other options for data include temperature and vibration (as suggested by comments).
