My way of installing oust fans in my humidor

[Shaun Raney]

I cut apart a box that I had lying around, used a 1 and 3/4" hole saw to pop two holes. You can also see the space that was made to allow me to fit the screens over it. I have since rewired it so that one fan moves opposite the other.

And the obligatory shot of the humi.

Nicely done.


Damn I wish I was handy!

I'm not familiar with this oust fan option, the one I have is the one with the D battery, a circuit board, and bulky as heck. Is the board built into those motor housings?

Very nice looking, btw. I will keep that design in mind when I move to a Fridge type arrangement. Just thought that it might be an interesting option to be able to out bead sacks in the box as well, keeping humidification right next to the air current, and neat and tidy.

You reversed one fans leads to allow it to operate in the opposite direction, but did you reverse the fan blade itself?

very cool setup!

what did that look like before you took it apart? I've never seen the model and it would surely save space to do it that way.

that setup looks like it would run constantly until the batteries are drained. I don't see any circuitry that would trigger the cycling.

ah....

damn nifty!

[Dgar]

Very cool... one of a kind, I like it

[dunng]

Very cool idea! Where's the beads?

Great idea. You've inspired me to try something similar. I'll post pics when I'm done.

You are gonna be glad I got a digital camera for X-mas.


Thats what the ugly little SOB looks like when you buy them for seven dollars in the store. It's massive, if I layed it on its back it would not fit in a "standard" size box. (The Montecristo Afrique Jambo box.) So what does any person who grew up playing with Lego's do? Take it apart and put it together in a new and exciting way.


I started by removing the battery cover and the battery. Then there are two small philips-head screws on the back that had to come out. Then to remove the front of the case from the back of the case you have to kind of pinch the fan housing and have it come apart as they use a snap type casing. And thats when you get.....


Thats what the "guts" look like. You can see the fan with the motor attached to it, the circuit board, and the battery holder (I installed the battery for the pic.) All of these guts slide out. You can re-arrange them in a myriad of ways, I'm sure...but one thing to keep in mind. IT'S VERY VERY VERY FRAGILE. I found out the hard way, and it's how I have pix of each individual component.

One thing that I didn't like about the the way that its set up is the the D-cell battery is attached to the board, not leaving me many options. So thats when i tried to attach the battery pack that you saw in the first picture. It was at that time that the fan moved about a 1/4 inch and then stopped. So I tried the second board. Same thing. Reattached the D-cell...low and behold... Destroyed the board. Probably just a resistor or a diode on it, but I don't feel like unsoldering all that tiny stuff.

Here are a few more pix, one of the back of the oust fan housing that has the switch cut-out:



One of the board front:




One of the board back with the switch off to the side:



Now you'll notice on the above picture, the metal "patches" that are right by the G and H keys on my keyboard. those are where the little clamps on the switch slide on. When the board is off...the one clamp touches only the large metal patch, and the other clamp just touches the board. When its on, the clamp again touches the big metal patch and the other then touches the smaller patch, finishing the circuit and applying power to the timer circuit and the fan.

Now as I said, I blew up my boards. They don't work anymore because I applied WAY too much voltage, 4x what is needed to run the fan. On top of that I tried running both fans off one board (this probably did more damage) and the draw through the board was HUGE. You'll see in the pic on the first post that I am using a 4 AA battery holder with a snap connector on it. Don't even think of using that if you want your boards to live. And only use ONE FAN PER BOARD. (Or if you feel like blowing stuff up in the name of finding a way to run two fans off one board, please do and show me how ). The only thing I can think to do right now that would still allow you to make the battery movable is to get one of these.

and then use wire so that you can mount the battery wherever, instead of having to use it in the fixed position on the board. And this will apply the 1.5 volts and plenty of amperage to the board that will allow it to use the timers. REMEMBER ONLY 1.5 VOLTS! NOT 6! (like I tried to do)

Yeah...i blew that up, I'm going to go to radio shack later in the week to figure out what to do.

hmmm wow that is cool...now if I can get computer fans integrated to the oust circuit board/battery setup...man now we would have something unique too!

Nice work
