Tom, I just noticed that you have added Voltage readings to gluonconfig (revison 81). Can you share some more light on this? is this done through the OSD?
Oh yes, before you start to hack your battery's connector: I simple use the connector of the balancing plug for this: very easy
With the extension board, a switched voltage convertor will use battery current to convert it to 5V to feed it to the gluon board. It can also be used to power the XBee/Camera/Video transmitter/...
