Title: Portable tethered power pack for Hasselblad
Post by: Zerui on September 09, 2012, 07:11:38 am

One of the weaknesses of my otherwise excellent H3DII- 50 is its inability to use the GPS accessory because it (the GPS) draws too much power, causing erratic behaviour in the camera. The Hasselblad UK service centre failed to cure the problem.  It goes away if I tether the camera to my PowerMac Pro.  But that is not alway sensible on photos hoots in the field, especially on small boats when photographing swimmers. See for example my book "The Joy of swimming".

What I need is a pocket sized power pack that I can connect to the camera via FireWire 800.

Can you suggest a suitable device?  It must be available in UK or Europe.

John

Phase One makes an ezpensive battery powered Firewire Hub. Alternatively I have used a 12 volt battery to provide power to an inexpensive Unibrain Brand Firewire Hub. Powered Hubs are made by several manufactures. The battery - hub combination should provide power without the need for a laptop.

You can ask to Silvestri in italy, look at their home page. They have a firewire battery pack for the H hasselblad on view cameras, maybe it work with the GPS.

John, I am sorry you did not appear to get what you wanted from Hasselblad UK. But I am a bit confused, the GPS power consumption (as far as I know) draws very little power, it is a very small solid state device, and I don't recall this being an issue with anyone else, also I think you are based in Italy so how did UK get involved?
Please supply more info here or call direct.

One thing I suggest to all my customers is a simple powered firewire buffer, remember that Macs (used to ) provide 10 Watts so aim for that.
