Sorry no, that was along time ago, think about 7 years, i unfortunately don't save all my projects... if i did i would have a barn full of speaker sets that i have made in my time...

But the basics of what you can do if you have a device/laptop/netbook to offer is to youtube some DIY projector to get the idea of how to build it.

The video you link to is a quick fun project to do, but you won't get much light, you won't be able to make a big picture, cause this needs more light.

But a conversion with some high powered LEDs can yield a very good "little" projector that can actually be used.
