Yeah, preferably something elastic or the contacts will be very unreliable. Ideally, you'd use spring-loaded pins to make the contact, so that you don't need to push the battery. You may be able to find connectors with suitable spring-loaded pins in old mobile phones or you could buy a new connector. Alternatively, you could also use pogo pins, but you won't find them at Radio Shack. Consider these product categories: http://search.digikey.com/us/en/cat/connectors-interconnects/rectangular-spring-loaded/1442900 http://search.digikey.com/us/en/cat/connectors-interconnects/contacts-spring-loaded-and-pressure/1442508 > so the pins touching the metal wall of the can is ok if it is just > on the outside?

Was thinking of something like this: http://downloads.qi-hardware.com/people/werner/tmp/batbox.png The only things crossing the wall would be the isolated parts of the plugs. The metal pins would be covered by the wood. You can allow a tiny gap on the can side as long as you can limit movement of the wood block such that the can can't touch the pins. (It all would be easier if the pins were fixed. Then you could simply isolate things with silicone.) - Werner _______________________________________________ Qi Hardware Discussion List Mail to list (members only): [email protected] Subscribe or Unsubscribe: http://lists.en.qi-hardware.com/mailman/listinfo/discussion
