Probably NiMH, maybe Li-Ion. Is there a difference in complexity for the circuit depending on the type used?

Hi all,

this is isn't exclusively Arduino-related, but I can't find any entry-level info on Google...

I'd like to be able to charge the battery in my Arduino device a) without removing the battery pack and b) while the device is switched on and operating. Same behavior as a cell phone or ipod.

I guess this requires a charging circuit in the device, a circuit decoupling it from the arduino while powering it at the same time, and a regular DC adapter. But don't really know how these would be implemented.

Can somebody point me in the right direction to learn more about this?

Thanks a lot!

Does this (300mA) only apply to the output pins, or to the main 5V output pin as well? I guess it goes directly from the dc regulator to the pin, so what is the max current there?

Thanks! I'm goign to wait for the series 2 pro, probably.

Hi everybody,

this is more a Libelium question, but I couldn't find any info on their wiki or product pages, so I'm trying here.

I'd like to use an XBee Pro instead of a regular XBee with an Arduino Diecimila to get a longer range. Is it possible to just swap the Xbee part for the Pro part on the regular Arduino XBee shield? There seems to be not shield with the Pro preinstalled. Do I have any other options?

... you need to use kalman filters, magnetic compass, and accelerometers. But arduino cant handle it.

I was thinking about IMUs and was wondering exactly that. Do you have any experience how many (Kalman-filtered) sensor channels you can handle in one arduino? Will the problems be timing related or memory related?

Oh, and... great project!  smiley
