  1. Mechanics This is not the best mechanical system and I am always open to new ideas and suggestions. Originally I started out with a plastic worm gear and plastic 50 tooth gear, always in contact with each other. Then one day I forgot the gears were ...

  8. This rain detector will give you a heads-up the instant it starts to rain, hopefully giving you time to close windows and bring in possessions. The battery-powered circuit draws virtually no current when the sensor is dry and the current ...
