What's interesting, my idea worked - it was tested, as I was told, on a subway tourniquet. Well, I am not guilty that such ideas come to my mind... but maybe my scheme would work with digicams, too? Just take something like old Metz 60 with lead-acid power pack
One of these and a cell phone jammer would qualify as nirvana for me....
