With a new baby, we are acquiring an astonishing number of battery-powered devices -- bouncy seats, swings, activity jumpers, mobiles, ... -- and burning through an even more astonishing number of batteries. Now I know why Costco sells those immense packages of AAs.
My wife asked me whether I could attach an AC adapter to our baby's mobile. I'd seen an article in MAKE
about modifying noisy toys, so I knew it was possible. It turns out to be surprisingly easy, provided you (okay, I
) don't make some dumb choices along the way.NOTE
The project I describe will
void the warranty for whatever toy you modify. The manufacturer (rightly) will not support you or provide you with assistance in doing this. If it works, be happy: If You Can't Open It, You Don't Own It. If it doesn't work, take it as a lesson not to meddle in the affairs of Corporations, for they are Subtle and Quick to Anger.
