I carry a doorbell receiver with me around the house in
order that the Aged P can contact me in case he suffers a
mishap. Unfortunately it's not terribly reliable because the
terminals of the AA batteries inside it are linked by a
springy bit of wire which is not anchored to anything and it
can easily slip out of place, so I have to keep fiddling with
it and testing it.
The stablest shape is supposed to be triangular. If
batteries were arranged in this shape, they could form a
more straightforward circuit without needing to be either
placed opposite each other or have an extra bit of wiring
to loop the current round. It would mean they were less
likely to become dislodged, make a simpler circuit,
meaning less wiring, and easier to remove and insert
without disturbing the other batteries one has just
inserted.
This is a triangular battery compartment with the AA
batteries forming the sides and conductive terminals at the
corners.
It would also overcome the tendency to base everything on
right angles, which would please the Skloodzi and the
trups.

I had a tiny bright led toy thing that was likely less than $1,
it had a tiny lithium rechargeable battery and a USB port,
That is so cheap I think AA batteries are not long for this
earth. They just need to make a version of your device that
makes sense. |

They can make those foil wrapped cheese wrappers pretty
cheaply though, so I think your idea has potential. |

Thanks [beanangel]. I don't think they can be around for
that long either although there's still the question of legacy
stuff, such as doorbells come to think of it. |

Could you not just wifi-enable your Aged P? |

You have to take flexibility, or the lack thereof, into
consideration there. |
