...i just have a kodak C190 12 mp camera (google it)...it has a video mode..
..i put a little foam rubber cushion between it and the front of my full-face helmet, and tape it to th helmet with electrical tape...along the right and left edges, staying off any buttons i need and th lens...
..can't see what i'm filming, but i'm usually watchin th road anyways...lol..
..takes some trial end error to get the orientation good, but it get's easier once you've done it a cpl times...
..it wrked well with my old cam, but i gotta get the sound right with this new one...
