I have a gamecube monitor and I need to know the cheapest, most effective, and easiest ways to attach it, power it, and attach the battery/what battery to use.
First of all it does not look practical. Secondly, attaching would be a problem but the only solution would be to use gaffer tape and bind it to whatever object you're gonna use it for. Thirdly, the power source would have to be a seperate one, thus it's own 12v battery. You would have to find and adapter that has the same power feed as this gamecube.
Have you removed the LCD from the bottom cube? For this to work you will have to run a video cable down the center of your post in your Glidecam. I'm not familiar with the Glidecam post, so you may have to see if this is possible. Also you will have to have some way of counter balancing the weight of the LCD and the extra battery so you can achieve static and dynamic balance.
Quite a bit of engineering to accomplish what you want, but it is possible.
