Thanks, Since the main focus of the project is power saving I would probably not want to use it to pull a pin to ground since that would require keeping the pin energized during sleep state. Since I have to order a shake switch I will try it this weekend with a piezo on the interrupt and see if that...

I am not familiar with a shake switch so I am imagining therefore that a shake switch would connect from the power supply to the interrupt pin and when it is shaken the switch closes taking the interrupt pin high. Am I envisioning a shake switch correctly?

I am trying to build a project that will have very low power utilization and be turned on with a knock detector. I was planning on using an attiny85 and a piezo disk sensor and have the attiny wake up once a second and check to see if there is a knock. Because the power output from the piezo is so m...

e-ink segment

It would be terrific to have (relatively) large e-ink segments. I'm thinking of something like 1" x 6" e-ink segment (all on or all off) that could be used to create large signs or large 7 or multi segment displays. I don't know enough about e-ink to know if a segment like that could be cut to size ...
