    Okay, not quite, but I figured that would get your attention. I've come across an interesting way to live a complete life without ever having to buy batteries. By some totally bizarre twist of marketing, a new Spinbrush electric toothbrush with batteries is cheaper than a pair of batteries by themselves. When they're drained to the point of it running too slowly, the bristles are about shot anyhow. Time for a new one. The batteries, meanwhile, are still more than adequate to operate my camera. The old camera batteries still have lots of juice for a flashlight, and when that gets too dim they go into one of my TV or VCR remotes. They all seem to reach their particular states of depletion at the same time, so the cycle continues. As a bonus, I get a new little motor and gear train from the old toothbrush to use for other stuff. :approve:

    How did you manage to get all that stuff to require the same size batteries? My frustration is that whatever thing has a dead battery in it usually takes the size battery I don't have in the house. Remotes take AAA, flashlights D, smoke detectors 9V, cameras AA. Nothing seems to use C batteries anymore, maybe those go in children's toys, and since I have no children, I have no children's toys lying around. :rolleyes:

    Now what can Danger be doing with all these?

    I get a new little motor and gear train from the old toothbrush to use for other stuff.

    Thanks, hon. I knew that you, amongst all of my friends, would truly appreciate the magnitude of this discovery.

    One of my lesser talents, but well noted.

    Well, basically, everything takes AA. As a side-note though, remember that all normal AAA through D batteries are 1.5 volts. The size has more to do with how much overall energy is available. I've had pretty good success using AA batteries in something made for C's, by shimming them with springs or tinfoil to make them fit the case. They won't last as long as the proper size, but they'll work.
    And your adult toys are all kick-start, right?

    Sorry to make an extra post for you, but the others probably wouldn't feel comfortable getting into a mix with the likes of us. Essentially, there's no reason for you to worry about what I'm doing with that stuff. If you happen to notice any of your sheep missing, it's purely coincidental.
