It took two and a half years, 60 prototypes, and even some of his children's craft foam, but former designer and sensor pro Curtis Ray found a way to stop his snoring. He built a "smart" sleep mask equipped with an accelerometer, a microprocessor, a Bluetooth connection, a valve, and a vibration motor.

"I grabbed my kids' art boxes and threw together a little mask made out of craft foam and had a one-way valve on it and put it on my face and slept with it," said Curtis Ray about the earliest iteration of his Hupnos sleep mask.

Curtis had an idea that night and completed a prototype with the materials he had on-hand. We want to know about your early invention ideas: What's the most interesting or spontaneous prototype you've ever made?
