A camera for my head

Hi all,

I'm still trying to find a helmet camera solution that I'm not too
chicken to use. All of the ones I've looked at so far have some snag
points that scare me a little, so I've not gone with anything yet.

I'm trying to put a solution together that means there is nothing
physically connecting me to the bike, so I've been looking for a decent,
but still affordable wireless solution. So far, the closest I've found
is at http://www.actioncameras.co.uk/acatalog/Wireless_Transmitter.html
and I was wondering what people thought of this.

I'm also not quite clear on how it would connect up, and I assume that
you still need the camera with the battery connected to it, so at a
minimum I'm looking at something like the image at
http://www.rfconcepts.co.uk/21CW-batt.JPG - is that right + the
connection to the transmitter and whatever power supply that requires.

The final thing I could use some advice on is the receiving end. My
current DV camera only does DV in, not AV in - can anyone recommend a
good, cheap videocamera to go on the end of this? Bonus points if anyone
knows of a Sony HC model with AV in that fits most skydiving helmets

I'd be quite happy to discuss this over one or more beers at my expense
with any London based people who've done this already and can give me
some pointers

Thanks,

Wayne
