Toy Inventor’s Notebook: Hack in a Hat

Often when pitching a company an idea for a new product, itโ€™s not what you have, itโ€™s what they think you have. That was the case when I presented this โ€œgame-in-a-hatโ€ toy idea. My idea: a preschooler-sized hat that uses a motion sensor and sound circuit to play a simple musical game. As the hat plays a song, the kid dances along (and the motion sensor monitors the childโ€™s actions). When the music stops, the dancer must freeze. If he moves โ€” RAZZZZZ! โ€” heโ€™s called out. Simple and fun!

But how to make a compelling presentation without having to build a working prototype? Instead, I made a hat with a speaker and pushbutton switch, both wired to an iPod through a wired control (such as the Apple earbuds with remote: makezine.com/go/earbuds). My switch was twinned to the circuit board traces for the โ€œnext trackโ€ button on the remote, and the speaker was connected to the audio out. Every time I pressed the button on the hat, the iPod would skip ahead to the next audio track!

I also recorded multiple audio tracks (including some silent โ€œspacerโ€ tracks) and made a cleverly sequenced playlist that simulated how the real toy would play the games. The voices and music played through the hatโ€™s speaker while Iโ€™d surreptitiously pressed the button to trigger the next audio track as needed to demonstrate the game. As long as I didnโ€™t deviate from my canned routine, the musical hat demoed exactly like the real thing. I wore the hat and danced or froze through my demo. The toy company loved it!
