Arduino crib rocker

Anyone with children will understand the value of this project immediately. This is an Arduino controlled sound activated crib rocker. [Lars] built a custom suspension system for his baby’s crib which allows a servo, mounted to the floor to rock it gently back and forth. Ok, maybe it’s a vigorous rocking, but that’s what some kids want. At least he’s safe and moderately immobile. He had to make a custom amplifier circuit to get his microphone working with the Arduino. It seems to all work perfectly now, triggering to begin rocking when it detects the baby’s cries. This should buy them a few extra minutes of sleep until the baby is truly hungry or annoyed. You can see a video of it in action and download the Arduino code on the project page.
