I'm starting this thread to discuss the possibilites of creating a poor-mans spectrometer from a webcam and a home-made spectragraph consisting of an old CD and cardboard tubing. This is probably going to be my first order of business.

I am also proposing growing with lasers, that's right, I said it, lasers. Just because I think I'm the first one to try something so ludacris. And with 6.5 billion people on the planet it's getting harder to find things to do someone else hasn't already done. Before you say I'll just burn and kill plants I'll say you might be right, but that's not going to stop it from being attempted. They would of course have to be diffused and the beam would have to be spread, but hey let's see what happens... ...pending I don't get too many irons in the proverbial fire at once.

it was pointed out to me that a blueray laser while not cheap, may be a common source for a blue laser as I'm planning on collecting most of them from used optical drives. Now.. in my research I found out two things, 1. a blueray laser has 5 leads and 3 different laser diodes in it, so it can put out ~400nm light ~650nm light and ~800nm light (don't quote me on the exact values I'm not looking at the specs right now) all in one neat little package... and 2. the laser in a blueray is the same laser emitter that was used in the now-defunct HD-dvd technology, and you can pick up an xbox360 hd-dvd from ebay for around the $30 mark.. *cough* generous donations are always accepted
