conversion of wet air into dry air?

There is a really very intresting topic about the conversion of wet air into dry air and vice versa with very less circuit design. the moto behind doing so is that i want to convert the wet air of any closed room into dry air and feed that dry air into my project on which i'm working.

Ionized air principles? Answered

I've looked throughout the internet, but I still haven't been able to figure out this one When air conducts electricity, say when lightning strikes, the electrical field breaks down air molecules... So, it breaks the intramolecular bonds between gas atoms in nitrogen molecules, oxygen molecules, etc. The atoms are then ionised. But then somewhere, I got the information that ionised air contains BOTH positive AND negative ions. How is this possible if the gases are non-metal elements and only form negative ions?? When an electrical current does flow, what carries the charge? The negative air ions? or electrons?  I've found sites that say one, and sites that say another. Thanks in advance

Air tank testing

I have recently acquired a 25 litre compressor on which the motor was seized so my plan is to replace the motor and pump with a couple of fridge compressors however the tank is more than 10 years old and although I cannot see any damage is their anyway to check it is safe to pressurize to 8 bar? it has 175PSI stamped on it so I assume its designed with that as the maximum working pressure but I want to know if I can get it checked as I don't want to blow myself and my garage apart if it bursts I'm in the UK

Forced Air Respirator?

I have a a AOS Safety respirator with P100 cartrideges and i think it is time to replace the cartridges, i have used it for hobbies when airbrushing, lathe working, fiberglass sanding, and enamel spray painting.  How do i tell when the cartridges need to be replaced?  Also i was wondering, would it be possible to convert it to a forced air respirator, by taking an old pair of cartridges and cutting out all the filters and stuff and attaching to air hoses, one to each cartridge and using dryer duct alluminum tape to make it air tight.  Then attaching some type of fan to it, or attach it to the houses a/c vent? Would this work?

Hacking and Air Rights

Wondering how wifi data, hacking and air rights work in terms of law and wireless security. If data packets are entering my "air space" why are or aren't I allowed to do with them as I want? So long as packets aren't injected or intended to alter private APs, I assume my air rights on my property trump other laws. I'm proposing no laws are broken; using legal, open software and or writing your own code. I honestly don't care one way or the other, I'm just curious as to what others know, or their opinions on the matter. A Google search with hacking, air, rights, etc..... turns up more than what I care to sort through.

Air Compressor RPM? Answered

I found an old cast iron 50 + year old 2 stage air compressor and I was wondering what RPM's I should run it at.  My dad says it is running much slower than he remembered and it is going 323 RPM's compared to the original gear ratio that would have run at 269 RPM's.  That should be dramatically faster, so could going too fast decrease performance, or something, or is there a reason the original motor may have slowed down? The RPM's are a complete guess based upon the 1725 RPM motor average.  The only reason I had to change pullies was because the original had FLAT BELTS (awesome) from back when people cared and build stuff right.  Now I have a v-belt on it and the compressor pulley wobbles by like 2 inches and the thing is out of line, but these shouldn't be slowing it down. Basically I need to know what RPM's I should be running the compressor at. P.S.  It can double as a vacuum  pump and it uses old fashion check valves!

Hi, Thanks for stopping by. I need to install some air ducting, but appreciate that my knowledge is seriously lacking. I have explored wiki, google, etc, but to no avail. However, if you know, please advise me! Essentially I need to understand the rules of ducting; where fan intakes/outtakes can be placed, how much ducting can preceed the fans etc. Also what do I need to consider when using Y flanges to combine/separate air-flows. Anybody know, please? Many thanks ;-)

Underground Tube Air Conditioning

I have long heard about using buried tubes/pipes to use as a heat exchanger to take the hottter air from your house, blow it through a system of closed loop underground pipes in order to use the earth mass as a heat exchanger. The earth mass removes/absorbes heat from the house air in the pipes and delivers cooled air back into the house. Can anyone direct me to web sites about this subject. Or, certainly, if you have knowledge about this, reply to me with it? Thank you, John333

Carbonate drinks with compressed air? Answered

So there are a lot of carbonators out there, and they all cost in the range of $50-$100, which is a lot, but the real cost comes form the co2 cartridges. So I was wondering.... why not just use compressed air? sure, it would take longer for all the co2 in the compressed air to reach equilibrium between the water and the air, but i do believe that if you let it sit for long enough, it would work. other gasses would also diffuse into the water, like oxygen, but since gasses are hard to taste, it shouldn't make a big difference. (co2 actually forms carboxylic acid, which tastes sour, but i can live with it not being exactly the right taste) all i have to test this theory is 115 psi from an air compressor... would this be enough?

my summer as AIR at instructables

My time as an Artist in Residence at Instructables went something like this:  I arrived in San Francisco and arrived at the Instructables office. I was (to be honest, though now I'm so embarrassed by this assumption) expecting cubicles. Instead, there was energy, vibrancy, and TONS OF COOL PROJECTS!!I There were electronics scattered about (which is, like, enough to lure me in for life :).  I  met Noah and a few others. After discussing some contract stuff, he told me to come by for some pizza and ice cream in the afternoon. Sounds pretty cool... So, I went to Tech shop, I was blown away by the amound ot 3d printers, laser cutters and other amazing fabrication tools all under one roof, all waiting for me to use :)  Then ... free pizza and ice cream, and a bunch of new people... sounds fun. I arrived at 4:30 and it wasn't  quite a party, just yet. it was a talk. And an extremely interesting one, with a big portion of the Autodesk community present. So I really started to get a sense of who was in the community, and where does Instructables fit in. Then, I got to see .. DRY ICE ICE CREAM!!! So cool. Actually  enough to entice me to order dry ice for a near future party! Anyway, I somewhat rapidly began to feel right at home. I ordered some parts for some projects and I began working straightaway. I started working on small electronics projects and other experiments related to water and boat robots.  The next day (Thursday) I got a call at 10 PM in the evening… It was Noah. I was working at Tech shop at the time (I tried to work at Instructables office in the morning then head to T.S. in the afternoon to do some bigger scale construction work in the woodshop.  Well, the Redbull challenge had been announced ("games") and they had begun brainstorming how to make… yes, remote control electric wheelchairs, that were controlled by a user who had a blindfold on, and would be listening through a wireless radio to commands from the person in the wheelchair with no control over themselves. Anyway, I headed straight over to Instructables, and the 72 hours began… The next morning, I head over with Randy to pick up our will-call items from Jameco, including arduinos, wireless arduino shields, xbees etc etc. Then we headed to Noah's shop in Emeryville… and the hacking began. An unfortunate thing was that I had to go to teach Arduino at Tech Shop Sunday evening, which is when the actual fun of riding the wheelchair occurred. Anyway, it was a super cool weekend of collaboration and intense work. Oh, and by the way, see here how to make your own: PSYCHO SCOOTER scramble, here.  The rest of the summer continued on, the biggest accomplishment for me was getting Sneel_003 built and tested in the water. A really cool next step would be to get some 123d catch of underwater objects, trying it out at the aquarium, then do some 3d printing of cool underwater stuff. I did various other projects involving wireless communication, using Arduino for various electronics projects, programming joysticks and remote controllers, etc. A really neat thing is that every day at 2 pm there is "show and tell" which is just a quick "go around the table and say briefly what you've done in the past day". So I really got to get a feel for the way that things were working, who was operating on what, what was happening in the office and out of the office. So I felt immediately a part of the family, in a sense. Instructables is a super cool place: the facilities were amazing, the people were vibrant and knowledgable and motivated and fun, and the experience was super. The facilities I used most were: laser cutter, vacuum forming machine, woodshop, tons of electronics, 3d printer… Everyone I met from Instructables and AutuDesk as a whole was super helpful and great to talk to. It is really a great community. Before I left, I gave a presentation of my work during my time at Instructables. Here are the slides:

Peltier Air Water Harvester

I was looking around at some of the air water harvesters tonight and of thinking about using a Peltier unit for one. Just started thinking and I know very little about either one of these. So my question is, could you use the cold side of a peltier to get an air current down to just below dew point causing humidity to condense on maybe a heat sink or something so it could be collected and use the hot side to create the air flow by a chimney effect? No moving parts.  Solar power it so it an be used anywhere in the world? Could be something that could supply clean water to people in need.

Air Traffic Control on PC

Air Traffic control broadcasts from 108 - 138 MHz. (https://www.instructables.com/id/Transistor-Radio-Hack/)A couple of months ago I bought a Realistic Jetstream radio. It was used. I saw it there before. I finally bought it. I thought it was just an FM/AM radio. It said AM/VHF. I thought that was odd. After I bought it I realized that it wasn't an FM radio, it was an Air Traffic Control scanner! That was even better. It comes apart just like the radio Kipkay used in the hack. It was already an ATC radio though. My question is there any way to get Air Traffic Control on your computer? I tried an old tv tuner card. I set the frequency to 122.8MHz. That is the frequency for the local airport in Microsoft Flight Simulator 2004: A Centruy of Flight. It is also what my radio picks up. The antenna won't pick it up on the tuner. FM radio works though. I hope all this makes sense.

Casing dimension to install Chilled Water Coil sizes for cooling

I need help on dimensions please. I need to build a box (casing) to install Chilled Water Coils and a squirrel fan to run well water thru for cooling a work shop. In short, I have very cold well water and want to take advantage of it. My shop is 50’ x 29’ x 10’ height. I’m figuring 14,500 cubic feet to cool. What I need to know is if a casing of 24” square that is about 5’ long would be enough to have one coil in front, fan in the middle and a 2nd coil on the other end? I will have a return vent and include at least 4 vents for air out flow. What I’m not sure of is how to calculate if I need to use bigger coils other than 24”? Do I need to give more information to get an answer? Thanks

Ceramic capacitor in air conditioner DPAC12010H

Hi there,  I received a not-working air conditioner model DPAC12010H from someone who didn't need it anymore, and I took it to a friend who works with refrigerators to see if we could find the problem. We took it apart, and we found that a fuse mounted on the main PCB was shot. The fuse is 120V and 3.75A so I suppose it's only for the control circuit as the whole air conditioner runs at more than 9A on max capacity. Anyway, we temporarily bypassed the fuse with a copper wire to continue testing. We plugged it in, and immediately a component on the PCB (which I now believe is a ceramic capacitor) spew sparks and melted it's insulation. However after this incident the air conditioner works perfectly, and it blows very cool air (its a 12000 BTU machine after all). However I'm still concerned about that capacitor. I can not post a picture right now, maybe when I get back from work. It was brownish yellow, about 3/4" in diameter roughly same shape as a nickel. Does anyone have any idea what that capacitor might be for? Since the air conditioner is working now I'm guessing the sparks made it conductive, or maybe it's used for the dehumidifier which I have not tested.  I will buy a new fuse today and see what happens. The air conditioner draws about 9 A at full operation. Any help would be greatly appreciated.
