Hello guys, please be gentle as i don't understand electronics. I have a problem that needs solving.
I would like to be able to build a rig to capture kingfishers diving underwater and film them. I will be using LED lighting to boast the light levels.
I will be filming with a Canon EOS 550D/T2i Digital SLR camera.
My issue is power, the waiting could be for many many hours and I am not planning to change batteries once the rig is set in the water.
My plan is to utilise the fake battery at the end of a power lead designed so that you are able to power the camera from the mains. I will chop off the transformer and just use the dummy battery, insert into the camera and now i have a couple of wires hanging out of the camera..
running the lead back to the river bank where i will have some sort of rechargeable battery pack, this in turn will be connected to a solar panel so I can run the camera in the field all day long with it being underwater in the river. (i plan to control the camera via a powered USB and laptop back on the bank)
The problem i do not know how to solve is what battery to buy and how to regulate the output, it must be 7.2V the battery it is replacing is a canon LP-E8, however the camera is just as happy running from 6 AA Ni-MH batts also so i dont amps sorry.
So please remember i need this to be very portable as i have lots of equipment to carry maybe a couple of miles across rough ground so a smaller battery ans panel would be better.
Can anyone suggest a solar panel and battery plus explain how i connect it together please, or at least point me in the direction...
I am UK based so Maplins is close by for me..water proof stuff would be good but not really essential...
Many thanks Phil - Bristol UK
