Aprilaire 700 Model humidifier loud noise when fan blows?

Aprilaire 700 humidifier operates properly; however, there is a horrendous noise being generated when the fan is only ( a vibration of sorts).  What could be causing this?

How would one create a mechanism to increase humidity in an aquarium for a reptile?

I have a large (55gal) tank with a tortoise & a large water bowl for the creature.  The substrate is soil which is kept very moist but yet the humidity in the cage is not as high as I need it to be.  I was looking at buying a contraption to help with this problem & read a review of one product.  The person who wrote the review seems to think this same product can be made with simple, every day items, however, the description regarding how to do this is not so enlightening for me.  I will post this below & am interested in someone 'filling in the blanks' so to speak & elaborating AND/OR presenting new ideas/contraptions.  Thank you!!!!!   This humid air exchanger is a simple design that consists of a plastic canister, a sponge that hangs vertically from the lid, a nipple on the underside of the lid, and two nipples on top of the lid to connect the air hoses (one connects to the air pump and the other obviously would be the humid air output). Had I done some research into the design beforehand, I would have just made one of these myself out of a two liter bottle, old plastic peanut butter jar, etc... A person who has the requisite knowledge and common sense needed to properly take care of a reptile has all of the ability needed to construct one of these according to one's own ingenium. In about 15 minutes or less you could make your own device and save yourself $12 plus shipping in the meantime. Might even be a quick and fun little project to involve the kids with. In the end, yes, this an effective device which could easily be built out of readily available household items.

How do I make my sonic humidifier work like it did when I bought it?

I tried replacing the filter, cleaning the hard white stuff(calcium deposits?), and the metal plate. I even bought a water conditioner shaped like a baby rattle that stows in the water tank, but no luck.

Can Sugru prevent an old, eroded rubber gasket from failing?

I have a great old Corona ultrasonic humidifier that is 21 or 22 years old. The humidifier works like a dream, but the old rubber gasket around the vibrating plate is going to fail soon. I am thinking that Sugru would be a fix to model around and on top of the existing gasket. Anyone think it would have trouble under water? It's one of the best old humidifiers  but has gone out of production. Have kept this sucker clean and in good order. The gasket has eroded considerably, and if it goes it will be a dead machine. I have repaired the broken water tank twice. I used a piece of Sugru to hold an old toilet flapper in place inside the reservoir tank and it hasn't moved in months. Anyone work with Sugru for things underwater? It is my only hope to keep this great old machine working. Sooner or later, it will go, but it is a grand old remnant of the days when we built things to last. My old metal blade fans are still going even after a switch had to be replaced. Good maintenance will keep things running  long after they are supposed to fail from use. Appreciate anyone and everyone's help. Thanks! Tess Elliott

Trying to figure out how ultrasonic humidifier detects low water level

Hello all, I'm currently working on a home automation system and have decided I want to throw my fragrance diffuser into the mix. What I'm trying to accomplish is I'd like the diffuser to come on whenever the unit has power so I can simply control it with a Sonoff SV. I was originally planning on just replacing the guts with an Arduino Nano or something until I tore into it and realized I have absolutely no clue how this thing detects when the water level is low! There's no sort of float switch or resistive fluid detection. In fact, the only part that has contact with the fluid is the ultrasonic transducer. I'm curious if anyone can look at the PCB and give me some more insight as to what's going on. On the far left the five pins coming into the board is the cable connector for the buttons and LEDs, the two large pins beneath that are the buzzer for making beeping noises when buttons are pressed, The SMD IC towards the middle is from what I can tell the brains of the operation. The three large pins (two with solder) near the top center are where 24vdc comes in. The two large pins on the upper right are for the fan and the two large pins on the bottom right are for the transducer. If anyone has any insight as to how this thing reads a low water level it'd be very much appreciated. Thank you!

How to make or salvage a humidistat and have it control a device?

I'm using a portable plug-in electric kettle as a humidifier. This is it: I have a separate little handheld hygrometer, so when I see that my room has reached a good humidity level I have to manually turn off the kettle. My question is, what is the cheapest way to make a humidistat, even from parts salvaged from other things, and have it control this? I have experience in electronics, circuitry, soldering etc. but I don't know where to begin on this one. I can provide any info such as specs on the kettle if needed. Appreciate any ideas and thoughts!

Increase room humidity without a humidifier?

Its the middle of winter and it gets very cold and dry here.  In my dorm room, the humidity is usually around 18%.  We aren't allowed to have humidifiers, so how can I increase the room's humidity?  Also, there isn't an air duct heating system; we use radiators.

Am I using this guitar humidifier correctly? Answered

I recently acquired this Planet Waves Acoustic Guitar Humidifier, and on the package it says no leaks because the holes are on the side. I can only store my guitar (in its case) on its side, so one side is facing downwards. I am putting in the minimum recommended water amount, but i am still worried it will leak. Will it leak? Will I have to store the case laying flat? I really don't want my new acoustic to crack or warp, but i also don't want it to collect water, as this will mess up the wood. Please help!!!

Cool Misty Morning Simulation

Here's an idea: Yesterday I was out on my motorcycle and it started to drizzle or mist very lightly. Helmet starts fogging so I open all the vents. The cool, clean and misty air rushing through the helmet was like a sort of inner piece. Like those mountain mornings or early fall mornings by the lake. Just gave a great feeling and I instantly felt refreshed and energetic. Anybody have an idea for recreating this feeling in a small space, say 10 x 10 room. I do have a cool mist humidifier for when I am sick but it is not nearly the same feeling. I've tried searching for some sort of product but have come up mostly empty handed and imagine it would be rather pricey anyways. Examples of said feeling: If you have a thought or idea I thank you plenty!!

How to safely remove led from my humidifier?

Bought tiny humidifier, big enough for bedtime but not so big as to ruin my electronics. It comes with a blue led behind the button that comes on when it’s on. The problem is that it’s very bright and disrupts sleep. I tried putting electric tape over the button, which helped some, but it continues to light up the water behind it. I want to remove it, but it looked like it is attached to a tiny circuit board, of which I have little experience. It is only one blue led, how do I remove it without destroying the circuit board and thus my humidifier?Note: I do have a soldering iron, but I'm afraid I'm gonna get solder everywhere and mess it all up because the push button part and the led are so close.

It only needs a stable 75% humidity and 12CThe idea is Ill have a sparkey wire up plugs into the humidifier, light, fan and fridge.. they all plug into my super sexy grey box that has 4 plug holes on it ( ill send you pictures)..The inside of the box - a 4 switch relay... to power the toys a connection and lead in that gives power…. And I have access to the liitle LCD screen to adjust the parameters when needed.I assume I need to get more electrical/computer parts for this.. and the program written that controls all this info.any info will be rewarded with salami.!!!!!!!

Functional intra nasal prosthesis

A patient had a malignant cancerous tumor removed from the nasal anatomy and is now left with no nose and no internal nasal structures that normally would filter, warm and humidify the inspirated air. Can anyone design a mini air conditioner that is light weight, safe to use, easy to clean, and affordable? If you do, then you can patent your device, and will probably be the first to ever create such a device. While there is no monetary reward, you would probably become known in the international medical community, and your device could be developed and marketed through the usual channels. As for me, I have nothing to gain. Its just that I am trying to help some colleagues who are now faced with this challenge. Anyone?

Solar Powered Dehumidifier Help

Hey guys. My dad, my brother and I have been pondering the idea of a solar-powered de-humidifier. So, it would charge using the sun's rays, and then use its power in the dehumidifier. This is something that could be used in parts of Africa with 100% humidity, and not alot of water. It is the perfect tool for anyone to use to obtain fresh water, by harnessing the sun's rays. We have a dehumidifier, and we really want to make it Solar Powered. We just need help in the way to power it.Would we charge a rechargable battery using the Solar Rays, or would we run it on solar power alone. The solar panel that I have been looking at is the Sunforce 50022 5 Watt Solar Battery Trickle Charger. Do you think that that Solar Panel is good enough? It is 5 Watts, so how would we connect it to our dehumidifier? This was the solar panel in the most recent PopSci used in the How 2.0 section. It is used to charge personal electronics. Thanks in advance.
