LOL! Yeah, Ken your probably right....
We all whinge about everything regardless of its merit. Take the *ist D for example...(I love mine incidentally). Has there been some bitching about this thing since it hit the shelves....
Cheers

Then we would have another PDML thread about those darn expensive Pentax Li-ion rechargeable batteries & why didn't Pentax do something else battery wise.

I disagree. The CR-V3 rechargeables are not the 'optimal' solution at all. An optimal solution would have been for Pentax too release the *ist D with a proprietry Li-ion rechargeable battery simalar to those used in other Pentax digital cameras. Then again, a fuel cell might be nice...

*Rechargeable* CR-V3's are the optimal solution. Yes they're pricey to get, at about 25 bucks EACH. Thats 150+ once you factor in the chargers, but, they have nearly the lifespan of a CR-V3, and more importantly, they provide FULL POWER even when only half charged... This is not the case with NiMH batteries whose voltage will slowly tail off until they run completely out.

BTW, I posted this once before, but I'm not sure if anyone noticed. I
"discovered" that the AC Adapter for the MUVO works perfectly with the
*istD! I haven't found anywhere that I can buy the AC Adapter that is
supposedly available to suit the camera, so one night, I got brave and
risked blowing up my camera by plugging the MUVO adapter in. I used it
solidly for 4 hours and it worked like a dream! I have used it many
times
since, with no bad side effects (well, none to my knowledge)...
LOL. Dare-devil.
I just checked the Muvo PSU, it's rated to provide 5VDC @ 280mA, the camera
specification are 6.5VDC therefore you probably won't cause damage but I'm
surprised it worked.
I'm not. Using the ist-D with 4 NiMH batteries (1.25 Volts each) provides 5 Volts total so we know the camera can operate from that Voltage. Computer-driven portable devices like the ist-D typically use many individual switching power supply chips (they're really tiny now) and don't rely on the raw power supply input for any of their subsystems. As long as the outboard supply can provide sufficient current it should be fine through a wide range of voltages. What's more, since the MUVO power pack is probably itself a switching supply, its failure mode is almost certainly going to be zero volts, rather than full unregulated voltage, like a linear power supply. In all likelihood, if there ever *is* a problem with the MUVO supply, it'll just go into over-temperature or over-current shutdown. No drama (but no power, either!)
