Well.... you could be a BIT more steady with the camera! Moving and shaking all over the place makes it very hard to watch.

And when you're filming something make sure people actually get to see what you are talking about/filming. Talking about the inside of a pc while i (as a viewer) can only see some molex connectors hanging is not entertaining at all. Same goes for the monitor, you simply can not read what it says on there. It's basicly a blurry mess.

Sorry...

*cries*

My camera reacts terribly to light... The only way i've been able to keep it steady is putting it under my chin and balancing, which is annoying but works sometimes.

Perhaps do multiple recordings of each part of the machine, that you want to talk about, and then put it all together in a video editor.
Voice was a bit low at some point. Well.... This happens.

I'm more or less making the same kind of video using my cellphone. I don't have anything to hold it unfortunately ... I've got a tripod, but I don't have anything that could screw in the tripod to hold the phone on it ... However, now when I need to show many things that displays on the screen, I just take a VGA to composite adapter as well as a composite capture card and that way I can capture the video coming from the computer. It looks terrible in comparison to the screen, but that's still much better than a shaky/blurry camera that shows the flicker of the screen.

I guess that everything has been said here : get something better to film (or at least something to stabilize it) just like I need
