I've a new JVC GR-DVP9 MiniDV camera that I need to be able to charge from the bike battery. The JVC website is quoting £50 for a JVC item! :} :} :} (The Japanese, they've such a sense of humour!).
If you think you might be able to help me rig up a cheaper alternative I'd much appreciate it. :bow:

The specs published in the manual are:

Power Reqmnt: AC110v to 240 v~, 50Hz/60Hz
Power Consumption: 23W
Output:
Charge - DC 7.2V (one long upper line, with 3 parallel broken lines underneath :dunno: :dunce: ) 1.2A.
VTR - DC 6.3V (one long upper line, with 3 parallel broken lines underneath :dunno: :dunce:) 1.8A.

The tricky bit will be connecting to the battery, as it has to be removed from the camera to charge.

Converting the bike's voltage to 7.2V is not difficult but coming up with a method of holding the battery securely while it charges on the bike may be a bit more of a challenge. It depends on how much of a bodge you're prepared for it to be I suppose. I have some of this (http://www.maplin.co.uk/Products/Module.asp?CartID=040508105704546&ModuleNo=35511&MR=N) stuff from Maplins which is quite neat. You may be able to use the battery as a former to create a battery holder from something like that and then add the contacts for charging :dunno: Unfortunately you're a bit too far away for me to offer to pop round and have a look at it for you (otherwise I would, honest ;) ).

The battery came with a plastic cover that clicks into place quite securely and neatly. I'd thought that a little modification with a sharp knife might allow for some suitable contacts to be fashioned, with a little Araldite or similar holding them in place. The leccy bit is the bit that I know nothing about.

Thanks for the offer of popping round, I'll put the kettle on.... :} :} :} :club:

Or alternatively you could go for a third party charger like this (http://www.smallbattery.company.org.uk/index.htm?http://www.smallbattery.company.org.uk/sbc_vc102216.htm) that works on mains or 12V for nearly £20 less. Depends on just how tight fisted you are ;) :}
