Bizarre weather clouds!

I just came across this article  that I had to share.  I thought it was interesting.  We are supposed to have severe weather conditions here.  We had a thunder storm in December last night.  Weird. . Sunshiine

Weather balloon photography

I have been thinking about launching a balloon for a while now, but was concerned with a few problems. I just found this: Which is good, because most of the other tutorials I've seen require one or the other. Other than this, does anyone have any tips about what kind of balloon/chute/tracking system I should use? What about the payload, what is it usually made out of?

Arduino wireless weather station

I built the Arduino wireless weather station that I found on a "Instructables" video. Everything works great and I love the project. On the 3.2" display I have one problem, the "outdoor temperature" gets all scrambled up almost like it doesn't clear the previous displayed temperature reading. The humidity and barometric pressure readings look fine. I can clear up the display if I press the reset button but within a few seconds it gets all scrambled up again. Any ideas what to do? Thanks again for a great project!

Under Attack!? Answered

I was watching the news and all over, the weather is going overboard.  Just saw China has some extreme snow. Even us down here are having more pronounced weather than before.  Hotter here now in summer and the rains are going absolutely crazy further up country.  Also went through extreme winds and rain awhile ago, much stronger than I can ever remember. Is this the climate change showing itself?

Cold Weather Bike Wind Deflector

So I've taken an indirect pledge not to commute to school VIA car - by not buying a parking decal... Since school started, I've commuted, by bike, nearly 400 miles. But now it's starting to get cooler. I really don't like riding in cold weather. I typically wake up cold, get ready (still feeling cold) and getting on a bike when it's cold out is pretty uncomfortable.... So, for my next ugly bike abomination accessory.... My first wind deflector fairing prototype. I made a model in SketchUp (this was my "learn to use SketchUp" project), then from that make a development drawing (3D shape to 2D cutout) and cut that out of some scrap cardboard (I've got quite a bit that I rescued). Yes, there are flaws in this design - it's my first attempt :p As of now, I need to figure out how to mount this thing. I currently have some surplus 1/4" threaded rod at my disposal, I'm going to grab some and see where it takes me :p Comments?

Ideas for winter cycling needed. Is it possible to have a removable "convertible" attachment on a bike?

My husband and I are thinking about selling our VW bus and living without a vehicle.  We take public transportation regularly for longer distances and bike a lot.  But selling our VW bus would mean that we would not be able to rely on it in times of foul weather.  I picture making a "convertible" cover for my bicycle, where I could cover myself during poor weather -- something sort of like the typical child trailer: But an attachment that would only be attached when the weather was bad.  I thought it would have to attach onto the rear wheel hub and the head tube and be primarily made of heavy clear plastic.  Can anyone here envision something like this?  Is it feasible?

Whistling blade on wind direction weather vane

I have a propeller with four blades that acts as a wind direction weather vane. What I would like is for the propeller to make a whistling noise when it is rotated by the wind. Someone told me if I put a small hole or a slit in each of the blades it will make a whistling noisy which should change with wind speed. Can anyone tell me what size hole/slit I would need? Also at what angle would the slit have to be? Or can you tell me any other way to get a whistle from the blades when the wind is blowing? The blades are metal and about 200mm long (400mm overall diameter). Thanks for any help. Lou

Observing "weather" (stratospheric temp.) with cosmic rays

An article in New Scientist reports on an analysis of cosmic ray muon data from the MINOS underground detector, which correlates with "sudden" (24-hour timescale) temperature changes in the stratosphere. The original article in Geophysical Research Letters gives you a good flavor for how this kind of analysis is actually done, and written up for publication. The figure below (Figure 3 of the article) shows the beautiful correlation between the temperature (5-day running average in blue) as measured by sounding balloons, and the muon rate in MINOS (also 5-day running average, red band with uncertainties). The alignment of the two curves is obviously not known a priori. The exact numerical calibration between muon counts (red, right scale) and temperature (blue, left scale) is a fitted output of the analysis, not an input.To me, it's just kind of neat that particle physics can relate so sharply to some "real world" large-scale properties.

Belarus Tractors-cold weather starting information?

Thank you for taking my question.  I purchased a Belarus tractor model 525 (65 hp. 4wd) new in 1990.  Although the tractor came equipped with glow plugs, they burned out shortly after I purchased the tractor.  I replaced the glow plugs again and they also didn't last long.  I then installed a block heater which heats the water and also a small heater from Wolverine company which actually glues on externally to the bottom of the oil pan.  Now although these products help somewhat, I was wondering if any of my good Instructable friends have had similar problems with these types of tractors and how they eliminated the problem.  The two heater items while they help, require several hours if not overnight to work.  Other than the cold weather starting problem this has been a good solid tractor.  In closing, I know these tractors are made in Belarus/Russia where the temps are far more severe than here in Southeast Missouri so I know there must be a solution.  One last thought, cold weather for these tractors is defined as any temp. below 60 degrees F.  Thanks, Debra Kay

"dry box" for drying clothes in humid weather

Hi all,I'm thinking of building something helping me to dry my laundry in the amazingly wet weather that I'm getting in the place I live now.I searched instructables for a while, but did not find anything that really applies. This might be due to the fact that I'm both new to instructables, and not a native English speaker. I might be using the wrong keywords.So I live in a very humid and foggy place, and it's winter now. When I hang my clothes out to dry, the process takes ages. Sometimes I think it might be working backwards: the clothes become wetter. Also, an unpleasant byproduct is that my clothes become smelly, despite they are clean. Sometimes, as a last resort, I hang my clothes inside the house. But my house is very small, and I do not really have a place for the clothes hanger. Plus, the house gets very humid and I am afraid I'm going to get mold. On the other hand, I have a rather large balcony, with a lot of place for the clothes hanger.Of course I could buy a clothes dryer. I actually use a coin-operated one for large items, such as bed sheets and large towels. But I'd rather not use a tumble dryer for my clothes.However I recently learned about heat recovery ventilation for houses, and I started wondering whether the same concept could be used to build a small-ish enclosure (a box) where air is kept warmer and dyer than outside, possibily in a controlled manner. Also, it would be very nice to get energy from the sun. Surely the walls of this box could be transparent, or black, to create some kind of greenhouse effect. Then I need a fan, to have the air circulating. The air could go through a heat recovery unit. This could probably solar-powered. On the other hand, I am not sure that solar panels would be helpful for heating the inside of the box by night (energy should be of course stored, but I do not think that would be enough).I see that something similar to what I'm thinking about is already on sale e.g. on amazon. These are called "portable clothes dryers", but they do not seem really optimized. They look like a combination of a hair dryer, a clothes rack and a tent. I do not think there is a real heat exchanger, or humidity control...Plus, they do not seem really safe, especially if operated outdoors.Can someone give me some advice, e.g. pointing me to projects that use similar ideas possibly for different purposes?Thanks a lotFrancesco

What crazy weather! (Might not see me for a while.)

So I might not be around for a while. Turns out Hurricane Ike still had enough steam to send massive wind damage through Kentucky and Indiana as well as multiple other places. My neighborhood is completely out - we have trees down on cars and into houses, and power lines down all over the place.Most of Louisville is without electricity and it's not sounding so good - they're saying 3 days to 2-3 weeks before everyone gets power back because we sent so many emergency personal to Texas to help them out. But now I have to go to class and then try to find a place that still has food, candles and batteries left. And a place to charge my phone. Even the power where I work is out and has been for two days. :P Wish me luck! It's a madhouse here right now. I can't imagine what an actual hurricane could do after this.There are lots of crazy pictures here:

Without paint - Protect Steel from Weather + Rust

Sometimes I'd like to protect steel from moisture without paint.  Partly this is a practical matter. Figure I'll weld somethin else on sooner or later, and would rather not deal with burning paint. Partly it's an aesthetic. Not long ago, saw a 50s pickup that someone was in process of restorin.  Just gorgeous while it was stripped of all paint. So... Linseed oil?  Wax? Or option C thru Z?

Any ideas for near space (weather) balloon telemetry? Answered

Hey guys, I'm considering a project like the recently popular near space balloon project. The only twist is that it could float for several days/weeks at a time. The major problem I have is that I need some way to reliably communicate with the system. The balloon would have to send climate data, gps data, and maybe photos. A video feed would be good too. I'd have to be able to control its descent and control its cameras. The issue I see is that many common systems are only good to about 40 miles which would still be way too short of a distance. Cellphones are obviously out of the question (way too unreliable up there). Satellite phones would break the bank. Power consumption is also a concern I have. I would consider getting an amateur radio license if you guys think it would help.  Note: I plan to use arduinos. JP Aerospace does some of the stuff I want to do with this potential project. The photo is their Away 46 mission.

Does anyone know how I could control the temperature of the air and the humidity in a plexiglass box ( 3 x 2 x 2 feet)?

Hi there! I am working on a project and I want to create adjustable weather conditions in a clear box. Being able to adjust the humidity and the temperature in the box would be ideal. I want to place an object in the box that transforms based on the conditions of the climate inside. I know my way around the shop, so fabricating a box is not an issue. I don't know where to start though with the devices. Thanks! ~Karla

Has anyone ever experimented with distressing vinyl to the point that it's all cracked and gnarly?  See the image.  Thanks.
