Are inputs up to 15V tolerant? Alot of battery chargers go up to 14.8V so if you want to be able to charge battery while connected it would be good to ensure whatever voltage regulator (not sure if onboard or a separate power board/deadbug) can handle. I use LM7805s which have input voltage up to 35V if you want to run on a 24v battery, not the most efficient but I have never had problems.

At tonight's meet/hacknight we'll be making prototypes of emergency power cables so people can power their mesh nodes in a disaster situation.

The idea is to make cheap, long, foolproof cables + instructions that make it simple to power mesh nodes from any 12 vdc source.

The thinking behind this is that the U.S. is full of cars and the most medium-term power supply in the days/weeks after a disaster will be car batteries.

A while back we ordered components for this from china and now that they've arrived we can make some cables and test how they work and whether we need better under-voltage/over-voltage protection.

See you at 7:30 pm!
