[Jay] sent us some details of a quick fix for a baby swing he owns, along with the unlikely place where he found replacement parts. We showed you a pair of his creations earlier this week, which you might recall. As luck would have it, the motor on the baby swing he modified burned out shortly after we featured his hack. Don’t worry – he didn’t break the swing when he hacked it, nor is there a Hack-a-Day curse. It’s purely coincidence, we swear!

The swing is about 7 years old so the burned out motor wasn’t that huge a surprise. After doing some research, it was looking like he would likely need to shell out $70-$100 for a replacement motor. He luckily stumbled upon a forum thread that said a motor from a cheap air freshener was a perfect match, so he gave it a shot.  Sure enough, it was the same motor, but with more torque. All it took was $5 to get the swing up and running good as new.

It just goes to show that you never know useful common items can be until you take them apart to see what’s inside.

Yes, you could argue this Nursery Room Temperature Monitor is simply an LED and an Arduino with a temperature sensor, but [Jay] really did put more thought into the process. For instance he stuck with AVR, built a wooden base and sanded globe, and even included schematics and source code. Plus, SIDS is no laughing matter and the more you know, the more it can be prevented. Back on point, one thing we would add is PWM for a more gradual change in color. What would you add?

We saw this home made beekeepers hood posted and actually mistook it for an art piece. We thought it was a Super Mario squid. You can see an example on this image, which is located on a site dedicated to cross stitching video game characters.

In an odd coincidence, not related to the 8 bit textiles above, we also found this Mario themed sweater. We wouldn’t wear it, but we’d love to see Wil Wheaton in it.

No. No no no. Bad Scientists. No treat for you.

There are 4 more links after the break, you’ll want to see them to get that baby out of your head.

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.

This surprisingly pleasant looking crib is actually a robot, designed to keep babies quiet and happy all night long. Once inside and locked up, the baby is under the robot’s care. When the robot senses crying, it rocks gently back and forth. This should allow parents the time to catch some sleep. As pointed out in the article, the $5000 price tag is a bit steep. Especially considering the fact that you can get a much less technologically advanced equivalent for relatively cheap. How many of you hackers have babies? What hacks did you do to get your babies to sleep?

[Corey Menscher] built the Kickbee while attending ITP this Fall. It monitors his pregnant wife’s belly and updates Twitter, a microblogging service, every time the baby kicks. The device makes everyone aware of the baby’s movement, not just the expectant mother. It can also log the baby’s activity to monitor development. The sensors are piezos held in place with an elastic band. They’re connected to an Arduino Mini which connects to a host computer using a BlueSMIRF bluetooth module. The host Mac does the logging and twittering.

This is one of the many projects on display at the ITP Winter Show.
