This is a great story for late night or a rainy day.... Anyone who grew up tinkering with gadgets has got to listen to this story by Steve Gibson. He telling a great story about making a device to keep a barking dog from pestering him on his walks home from school. Reminds me of a Tom Sawyer or Our Gang type story.
