Here is a parts list that covers the boxes used in the laser project. The most costly part of this is the packaging. Just bear in mind that I started out without the enclosures and jacks and plugs.  You can use what you have avaliable out of your Junk box. 

The receiver tube is no more than a peice of pvc pipe and a couple of connectors and a magnifier. I found glass with a short focal length works best for me.

The transmitter with motors is not needed but makes it easy to get alinged. I started with 2 cheap tripods they worked but was hard to get alinged.
