I built this the other day, I added some necessary things that many other homemade jobs are missing,, I have a 0-10psi regulator so I can get 1/2 psi or around 13 inh20, I added a pressure gauge and a shut off valve so I can check the evap for pressure drop.
the oil I used is baby oil with AC UV dye added,, it really works great. I used a nichrome wire wrapped around a wick that's powered by a dimmer switch, the unit draws about 6amps turned on max.
here are some pictures and a video of it working
