The whole project took 4 weeks due to waiting of parts and waiting for spare time to build it. The box took the longest to build. But if all the parts are available, it would be about 6 hours.
Here's the result
3 meter tall on a factory wall!!!

This is a more reasonable size at home for gaming and movies

This is the prototype using cardboard boxes, do i smell something burning???

This is the first image that we projected, a plastic bag, notice the $10 Australian note.

Comparision of my 82cm TV and the projection

Next post, i will show the step by step of the build of the box and all the parts.
