This is pretty cool. He combines a handful of cheap, off-the-shelf components with some simple mechanical pieces and creates a neat machine. 

How dark the room would need to be in order to have a bright image could be an issue, and I don't know how you could determine that without actually trying it. If the room has to be absolutely pitch black, that could be a problem. You could bump up the LED to 200 Watts, but then you are going to need more cooling and if you want it to be quiet you might need to resort to water cooling, which adds another complication.

Some technical skill is needed. You need to understand simple electrical wiring, be able solder hookup wire, and take apart a smart phone. You also need to understand the specifications well enough to order the correct components.

The biggest problem is cutting the holes in some 1/8" aluminum plates. It could be done with a drill, a saber saw or an angle grinder and a file, but it would be messy, noisy, tedious and if you weren't very careful the holes would be ugly. However, since they are all on the inside of the machine and invisible on the outside, no one but you would know.

Or you could have SendCutSend cut all the aluminum parts for you. Takes a few days, and you would have to produce electronic drawings of the parts you want. There are probably other places that can do this as well, but SendCutSend is the only one I know of.

I was surprised that he used vinyl instead of paint. I like painting, but I don't do much of it. Preparation and cleanup are more work than the actual painting and not nearly as much fun. Plus there's the drying time. Vinyl with a pebbled surface is not going to show surface imperfections as readily as paint. Anodizing would be best, but that's another process that is best sent out and is going to take at least a couple of days if not weeks.

If I were to tackle this project, I estimate it would take me about a week of time and $500 to complete. I'm slow and $500 might be low.
