I made something similar last year, but there were a few issues I discovered after using it. The new version provides a larger reservoir, makes it easier to change nutrients and uses a simpler spray bar with fewer nozzles, which don't require tapping to fit. The entire video is around 25 minutes long. I broke it up into three parts. I just posted part one, and will publish two and three over the next couple of days. The thread for the old version is here http://thehotpepper.com/topic/60206-inexpensive-low-pressure-aeroponics-system-design/
