In general, I don't see why not. Some may have fancy internal electronics that only let you use the battery if you speak the right magic words to it, but most of them are probably just plain batteries with a bit of protection circuit. > Perhaps by attaching some type > of wire or even a lead with a clamp to the battery and contact > points on the Nanonote, more 3.7V batteries can be used? Things in there are quite cramped, so I think it may be a bit of a challenge to fit an adapter plus the battery inside. The Ben's battery is slightly longer than some of the more-or-less compatible batteries, which will help, but we're still talking about maybe 0.2-0.3 mm of extra space. If you plan to permanently switch to some other battery and don't mind a bit of hardcore rework, you could try to unsolder the existing header, make a small PCB with a suitable contact (short pogo pins may work) and glue it to the opposite side of the plastic wall of the battery compartment, with holes at the appropriate locations. Objects you'd interfere with there include one of the screws in the battery compartment (probably not really necessary) and - if you need to go all the way to the opposite corner - the microphone. If you just want a way to attach a battery for some stationary use and are happy to use the Ben's original battery elsewhere, you could make a battery-sized block of some suitable material (e.g., wood), put contacts on one side, and run wires to your real battery. If you can make a PCB for the contacts, this should even look fairly neat. - Werner _______________________________________________ Qi Hardware Discussion List Mail to list (members only): [email protected] Subscribe or Unsubscribe: http://lists.en.qi-hardware.com/mailman/listinfo/discussion
