Okay, here's the situation:
-I want to plug a boom microphone into my Canon HG20 camera, which has a non-powered 3.5mm audio input and a powered audio cradle.
-I have a fairly good quality Olympus ME31 3.5mm mic which produces excellent audio quality when I record stuff on my computer.
-Unfortunately the mic requires an external power source which my camera apparently isn't providing, so the mic does work on my computer for example but not when attached to the camera.
-The camera's powered mic cradle only works with Canon equipment, and the only Canon mic I can find for it isn't suitable for boom work as it attaches to the top of the camera.
What can I do?
I've tried looking on the web for a solution to this problem, but the only things I can find are scary complex-looking electronics projects involving circuit diagrams and soldering irons. I'm not really up to the job of building my own power supply, nor would I dare attach a self-built power supply to my camera.
Is there any kind of off-the-shelf power system that could let me power the microphone while it's plugged into the camera?
I've even got a pretty good improvised boom pole (a telescopic carbon-fibre fishing net handle) so everything else is in place, I just need to find some way to get the microphone powered.
