Hi everyone, I'm working on this project for a science fair project: http://www.makezine.com/01/123/ or http://www.scitoys.com/scitoys/scitoys/magnets/gauss.html and I was wondering if anyone new of a good way to measure the acceleration of the magnets? Thanks for the help! ;D

I recently started a project of converting a Powerbook to a media center that would stay attached to my entertainment center (will use CenterStage as interface). So my question is, what are the bare bones essential parts of the Powerbook that I would need to have a rumming system? I'm scrounging parts and buying from Ebay. Currently I have from a 12" Powerbook: * 1.33ghz logic board DVI * DC to DC board * Inner Frame (with fan) * Heat Sink Now the obvious parts needed would be ram, hard drive, and DC In Board. Don't need the battery and the modem nore the speakers. Don't need a display but a touch screen would be nice. ;) Probably should put in a superdrive. A case like this would be nice! But what can I exclude and still have a working system? Any and all help/info is appreciated! Jim
