The Curious Incident of the Dog in the Night

Sometimes you can't teach an old dog new tricks. Tired of trudging down the stairs to let his dog out of his cage in the middle of the night, Les designed a remote control door opener. The system consists of a clevis mounted to the shaft of a solenoid and the door latch of the cage. When Les activates his handheld remote control, 120V power energizes the solenoid and pulls the latch open, allowing his dog to open the cage and run free while he stays snuggled under the covers upstairs.
