No more batteries for the Fisher Price aquarium


Brad “fixes” the Fisher Price aquarium [Helen’s public gallery at Picasa]

Elena loves her Fisher Price aquarium. In fact, she loves it so much, she turns it on several times a night. As a result, the aquarium, which takes four D batteries, goes through batteries like I go through grapes. (I like grapes. Note the nearly empty bowl of grapes in the pictures.)

We’ve got rechargeable D batteries, and they work fine, except for a couple of issues. First, they only last a couple of weeks on a charge. Second, when the batteries are run down, the aquarium goes from “works fine” to “sounds scary” pretty quickly.

Enter Brad, the guy with the electrical engineering degree. I found a power adapter, formerly used for an old Palm, and rigged it up to the aquarium. I checked voltages to ensure everything was okay, and voilà! Now she can turn them on as often as she wants.
