Hello folks.
Actually, polarity sensing is a trivial problem from a hardware standpoint,
requiring only minimal components to prevent damage from wrongly-positioned
batteries. In fact, in most battery-operated equipment sold these days, it
is difficult to damage anything by placing batteries in the wrong direction.
For all I know, the Springer design people may already have this common
diode-based protection built in to the device. While I don't suggest that
anyone test this hypothesis, it would be useful to know if the BookPort can
be damanged by incorrectly positioned batteries. I would be quite surprised
if any damage at all would result.
Someone asked why so many manufacturers have gone to uniquely clips. Easy!
Fewer components, less expensive.
Cheers,
Jerry
