    I think the better option would be a stage fogger LOL. I bet this would look badass, fogging up a pond with LEDs! Makes me want to get a koi pond!

    I could see myself sitting on the porch with a bong and a fishing pole, catching my fish and throwing them back LOL :bigjoint:

    Thanks for posting this, motivated me to hack my cheapo humidifier to bypass the power switch. 20180125_131540.jpg
    This way I can control it with my arduino easily. And if it breaks I'll just get one of the nebulizers you linked to.

    Thanks again.
    :hump:

    It works really well! They love the cool fog blowing through the leaves, and I think the plants may be foliar feeding from the mist! I've got my exhaust fan running now, and the rh dropped to around 40%. However, I've got the fog flowing right through the leaves, and I think it's still providing beneficial moisture. If I turn of off my exhaust fan, the rh in the closet will jump to 75% within a minute or two.

    I wasted my money on an Evaporative Humidifier with a 1 gallon tank. It barely helps, added 2 - 1 gallon bubble buckets and I'm getting up to 20%. It's winter, dry, and I'm running open hood. If this thing will kick some fog, I could plug it in my humidistat control and be done with it. The evap humidifier is a little sketchy in a grow box, that Evaporative wick filter is bound to grow something nasty at some point. We shall see what happens. I'm in it for $26.

    Looks more like the bongs I used to make in college .

    The automatic dog bowl works great, I think it probably would work better if the mister was a little lower profile. It works with the metal one I got, but the plastic one required a little more depth. I got the taller profile plastic one not the low profile one. That's why I built what is in the pic, so I could fine tune the depth.

    I've decided to rebuild my fogger setup. I know I can get more for with a deeper tub, and it's not something I can dial in with the dog water bowl. I wasn't going to build anything exotic, or anything, so I started looking at all the plastic food containers I had. Besides, my dog wanted her bowl back LOL!

    As a side note, the power supply, for the fogger I was using, got a bubble on the surface, so I returned it. AFAIK, this isn't a common issue. I've had the same foggers run for months without any issues. I did end up getting a different one, around the same size. I think it puts out a little more for. It comes tomorrow, so I'll post some pics of the results.

    Basically, all I did was take a gallon water jug, and mount a barbed adapter in the cap. I carefully drilled the hole, and used my Dremel to shave the hole, until the fitting would tightly screw in. I've got a whole bunch of o-rings, so I put one on both the outside, and inside of the cap. This almost sealed it perfectly, but I started to see a very slow seep. So I used aquarium silicon in the o-rings, inside of the cap.

    Here are the parts I used. The clear Tupperware container is a base for the water jug, since the jug will be upside down.

    I used scrap wood for the wood base. They didn't have the most perfect edges, so to be able to level it, and fix any rocking, I used screws.

    Finished, and in action...
    PSX_20180219_144556-1401x2783.jpg

    The water jug has to be completely air-tight, so that the vacuum is created, keeping all the water from pouring out. It was much easier to mount the adapter in the lid, rather than the body of the water jug. Different lengths of black tubing can be used to dial in the right water level. If I put a little longer tube on the lid, it'll lower the level in the fogger reservoir. I can even put the jug on a shelf, and use a longer length of tube, to go into the fogger reservoir.

    Also, I spray painted the wood several times, to seal it. Having porous wood would cause problems.

    I didn't think it was possible to spend even less on building this LOL!

    BTW, when turning the water jug upside down, the water doesn't just pour out and make a huge mess. It actually glugs out really slow, and makes no mess.

    I gave up on using the water jug. It wasn't strong enough to handle the vacuum. It was collapsing as the water was pouring out. So, I went to a container that I know is strong enough. I'm sure I can find a strong 2-gallon jug that would work, but this will work for now.

    I drilled a 1" hole in the lid of an air-tight Ball Mason jar

    I used an o-ring on both sides, and screwed them together tightly.

    This is the new nebulizer I got. It puts out a little more than the other one, but I'm not sure I can take it apart to clean it, or replace the disc when it wears out. I've got another one of the original nebulizers that work with this power supply.

    So far, it's working really well! The larger pump and nebulizer put out a decent amount of fog.

    Nice. Looks like the one that is my pvc rig. I found with my pvc one the resivoir holding the mister gets warm under continuious operation, probably should have used another 4in diameter piece for more water volume instead of the 2in. but then I also dont have an airpump pushing the fog out.

    Have you though about just using the country crock lid with a hole for water feed and hole for airhose instead of the cup?

    They do get warm, regardless of the amount of water they sit in, so I wouldn't worry too much about that.

    I tried out a few ideas with the Country Crock lid. The problem I was running into was that I couldn't easily turn the bottle upside down, and get it into the container, without making a water mess. The water pours out really slow, but it was still spilling water. With the lid off, I can turn the bottle upside down, above the open container, and have enough time to get it in place. I also tried a few different containers for the nebulizer, but went back to the blue cup, because it's narrow, leaving room in the CC container. Besides, all the holes were already cut. :)
