I want to make an audio-to-vibration bracelet for my deaf partner. I need help! Answered
I have a new baby and my deaf wife can't hear the baby at night.
I want to make a bracelet that vibrates with sound over a minimum volume.
I thought about using a Raspberry Pi Zero, but it seems like overkill (and large!). Is there a simple circuit I can make that could house a microphone, vibrator, battery and some chip to make it work? I'm pretty green to circuitry in general so need some handholding if possible.
