Redditor [mulishadan] — a fan of the movie WarGames — has created a singular thermostat in the form of a Defcon alert meter.
Looking to learn some new skills while building, [mulishadan] tried their hand at MIG welding the 16g cold-rolled plate steel into the distinctive shape. A second attempt produced the desired result, adding a 1/4-inch foam core and painting the exterior. Individual LEDs were used at first for lighting, but were replaced with flexible LED strips which provided a more even glow behind the coloured acrylic. A Particle Photon board queries the Weather Underground API via Wi-Fi in five-minute intervals.
Each escalation in the Defcon alert signals an increase of 10 F, starting at Defcon 5 for 69 F and below, up to Defcon 1 for 100+ F. The final build looks like a true-to-life prop with some useful functionality that can be adapted to many different purposes — proof that a relatively simple project can still produce fantastic results for entry-level makers. So why not try making this thermostat scarf as well?
Physicist and squirrel gastronomer [Carsten Dannat] is trying to correlate two critical social economical factors: how many summer days do we have left, and when will we run out of nuts. His research project, the Squirrel Café, invites squirrels to grab some free nuts and collects interesting bits of customer data in return.

What would you do if you suddenly went blind and could never again see the sun set? How would you again experience this often breathtaking phenomenon? One answer is music, orchestrated by the sun and the Weather Warlock.
Built by the musician [Quintron] (builder and inventor of insane electronic instruments), the Weather Warlock is an analog synthesizer controlled by — you guessed it — the weather. It translates temperature, moisture, wind and sunlight into tones and harmonics with an E major root chord. UV, light, moisture, and temperature sensors combined with an anemometer set up outside feed the weather data to a synthesizer that has [Quintron] dialing knobs and toggling switches. The Weather Warlock steams 24/7 to the website weatherfortheblind.org so that the visually impaired are able to tune in and experience the joy of sunrise and sunset through music.

Hollywood would have you believe that tornadoes are prevalent in the Midwest. We’re much more likely to see hail in the springtime—balls of slushy ice that pelt our roofs and dimple our cars. [Dr. Ian Giammanco] and his wife and fellow scientist [Tanya Brown-Giammanco] have been studying hail at the Insurance Institute for Business and Home Safety’s research lab since 2012. In 2013, their team created over 9,000 artificial hailstones and fired them at a mock-up of a house in the first indoor full-scale hailstorm.
As fun as it sounds to shoot balls of ice at different things, they did it to better understand the humble hailstone and the damage it can do to insurable goods. Those hailstones from a few years ago were created manually by injecting molds and freezing them. Recently, [the Giammancos] and have taken a more advanced approach to creating artificial hail so they can study the physical characteristics. They scan actual hailstones in order to create models of them. Then they make a 3D-printed mold and use it in a hail-making machine that uses diffused carbon dioxide to mimic the layering that occurs when natural hailstones are formed.
While it would be nice to be able to control hail, the next best thing is mitigating the damage it causes. The better that scientists understand hail, the better materials will become that can withstand its impact. Perhaps someone can perfect a shape-shifting building material and make it resistant to hail.
The magic glowing orb that tells the future has been a popular thing to make ever since we realized we had the technology to bring it out of the fortune teller’s tent. We really like [jarek319]’s interpretation of the concept.
Sitting mystically above his umbrella stand, with a single black cord providing the needed pixies for fortune telling, a white cube plays an animation simulating the weather outside for the next six hours. If he sees falling drops, he knows to grab an umbrella before leaving the house. If he sees a thunderstorm, he knows to get the umbrella with the fiberglass core in order to prevent an intimate repeat of Mr. Franklin’s early work.

Word clocks are a neat twist on traditional timepiece user interfaces. Spelling out the time with words and phrases rather than numerals fancies up a clock nicely. And if you add the current weather and forecast to the display, you get this attractive and handy word-based time and weather display.
For this clock, one of the many custom builds on [GMG]’s site that betray a certain passion for unusual timepieces, an 8×32 array of Neopixels lives behind a laser-cut sheet of steam-bent birch plywood. Each pixel is masked by either an alphanumeric character or an icon representing weather conditions. An ESP8266 fetches time and weather data and drives the display serially, controlling the color of each cell and building up the display. The video below shows the clock doing its thing.
Sure, we’ve featured plenty of word clocks before, even some with weather display, but we like the slim and understated design of this build. We’re particularly impressed by the lengths [GMG] took in packing as much capability into the 256-pixel display as possible, like the way “today” and “tomorrow” overlap. And if you’ve got an eye for detail, you might spot what gets displayed when it’s over 80° and 80% relative humidity.

Bob Dylan may not have needed a weatherman to tell him when the wind blows, but the rest of us rely on weather forecasts. These, in turn, rely on data from weather stations, and [Vlad] decided that his old weather station was in need of an upgrade.
His station, which uploads live data to the Weather Underground, needed to be solar-powered, weather-proof and easy to install. He seems to have succeed admirably with this upgrade, which is built around an ATmega328 and the 433 MHz link from the old station. As part of the upgrade, he built a 3D-printed enclosure and installed all-new sensors on a home-made PCB that are more accurate than the old ones.
He looked into upgrading the wireless leg to WiFi, but found that the school’s WiFi had a login page that he couldn’t get around. So he re-used the old 433 MHz radio and connected the other end of the link to an old laptop on the wired network. Good enough, we say. Now how about a snazzy display to go along with it?
