1-2-3 Steps for building one from scratch

Hi all, I'm new to the forum and have read several threads about the DIY LCD projectors. Most of the them were discussions on the progress or what material to use.

Would like to find out the steps to build up one from scratch.
Can any kind souls provide the link to the thread if there is one?
For DIY Projector TV, DIY LCD projector and DIY Video projector.

Have found the general idea for DIY LCD projector at http://www6.tomshardware.com/howto/20041113/projector-01.html but not sure whether is there any newer designs.

However, I do not know the difference between the diy video projector and the lcd projector. Is it one uses lens and mirrors, the other uses the lcd?
