When you're a kid, there's nothing like a good bedtime story from someone you love. This custom recorder can attach to any children's book and let your little one listen to you read it to them even when you're not there.
Using a small development board called Foxonix, Instructables user newdigitalboy built the perfect way to read to kids while away. All you need to make your own is a little soldering know-how and a way to do some audio recording.
There are pre-made books that do the same thing out there, but they can be expensive and have limited options to choose from. With this you can record yourself reading any of your kid's favourite books, and they can pretty much be as long as you like.
Check out a video of it in action here and see the complete instructions at the link below.
