Aba, my head Hertz!

It’ll be a while before my daughter can talk, so I was excited when I saw this on BoingBoing. Then I read the page and calmed down. First, I’d need to have WAY more electrical engineer tendencies to put this together. Second, the receiver has to be hooked up to a PC parallel port; the nearest PC to our bedroom is in the guest room, PAST Hadarya’s room, making this pointless except for data-gathering purposes, and I don’t really need that. Still, it’s a cool idea (no pun intended, really), and instructive in its own way.
