Glass weather indicator1/9/2024 ![]() The weather indicator is really handy - let's build one! ![]() I'm really looking forward to seeing what else it can do. By the end of the day that I built this project, it could already also be used to track packages or tell time. My theory was that the geeks I work with would be unable to resist writing other applications for the shiny new toy, and it turned out I was right. It turns out to be a snap to build, and not expensive! This seemed as good a place as any to start, so I connected an Adafruit Neopixel Ring to the internet with Electric Imp, cooked up some animations, and set it up to grab the forecast from Weather Underground. ![]() I've had a theory for a little while that just a dozen (or two) pixels and an internet connection are all you need for a seriously vast number or applications. When it comes time to make the trek down the street to get some lunch, I'm never quite sure what I'm going to find in the great out-of-doors. In my case, my coworker at the desk across from mine has the window seat. Once the liquid turns clear, it is ready to go.We can't all have the desk next to the window. During this time, avoid picking it up and shaking it as this will disturb the acclimatization. Allow the device to acclimatize for a week to let the liquid settle to its current atmosphere. Keep it away from direct sunlight, heat sources and cooling vents. To get this beautiful instrument yield accurate results, place it on a level surface. ![]() Even when you’re doubtful about its predicting ability, its chic design will surely make an interesting conversation piece. This weather predictor comes in the form of a neat cloud-shaped glass on a wooden base. Large flakes floating on top indicates stormy weather. Crystals forming at the lower corner of the glass means windy weather. Small dots in the liquid indicates a high chance of rain. Cloudy liquid means cloudy weather with chances of precipitation. If you see clear liquid, it denotes clear weather. Inside the transparent cloud-shaped glass is the special liquid that crystallizes in different patterns in accordance to the changes in the surrounding barometric pressure. That’s exactly the concept behind this weather predictor. This special mixture has the property to respond to the changes in atmosphere through crystallization. The liquid inside the clear glass is a mixture of ethanol, distilled water, potassium nitrate, ammonium chloride and camphor. But how does this instrument foretell the weather? Is FitzRoy’s claim about this device true or not? Well, let science do the talking. However, they are now considered a decorative piece rather than a weather predicting device. Well, guess what? Storm glasses are recently resurging. This explains why many people do not even know that this instrument ever existed. Despite FitzRoy’s endorsement, storm glasses fell out of favor when cheaper mercury barometers were introduced in the 19th century. ![]() During his voyage with Charles Darwin aboard the HMS Beagle in 1831, FitzRoy claimed that the device helped him forecast the weather with accuracy. This instrument is actually based on a classic device called ‘storm glass’ which was popularized by Admiral Robert FitzRoy. With this decorative weather predictor, you’ll never get caught in the rain again because it will tell you right before it happens. And now you’re probably wondering why you haven’t already got this convenient and functional weather predicting instrument. So, should you cancel all your outing plans for today or should you take a leap in the dark and proceed anyway? If only you had this storm cloud weather predictor that can tell you if it’s going to rain or not. It’s looking dark and cloudy outside and it really looks like it’s going to rain. ![]()
