Hey gents, I was just thinking about it, and I don't have any idea how a vibration sensor works? Anybody have some knowledge to share in this area? I was thinking about how airplane engine props can be balanced to reduce the vibration, and I was thinking of trying to build some sort of a vibration sensor, or hook one up anyway, to monitor electric motors, to indicate when they are approaching failure.... thanks -- http://www.piclist.com#nomail Going offline?
