If you’re anything like us, your complete shoe collection consists of a pair of work boots and a pair of ratty sneakers that need to wait until the next household haz-mat day to be retired. But some people have a thing for shoes, and knowing which pair is suitable for the weather on any given day is such a bother. And that’s the rationale behind this Raspberry Pi-driven weather-enabled shoe rack.
The rack itself is [zealen]’s first woodworking project, and for a serious shoeaholic it’s probably too small by an order of magnitude. But for proof of principle it does just fine. The rack holds six pairs, each with an LED to light it up. A PIR sensor on the top triggers the Raspberry Pi to light up a particular pair based on the weather, which we assume is scraped off the web somehow. [zealen] admits that the fit and finish leave a bit to be desired, but for a first Rasp Pi project, it’s pretty accomplished. There’s plenty of room for improvement, of course – RFID tags in the shoes to allow them to be placed anywhere in the rack springs to mind.
From plain and utilitarian to the sleek and professional, there are a lot of ways to build a multifunction weather station. We’d thought we’d seen it all here, but building a weather station into an IKEA lantern is a pretty unique presentation.
There’s an active community over at ikeahackers.net, and the variety of IKEA hacks they’ve come up with is pretty astounding. For this weather hack, [Richard Stevens] chose the Borrby, a $15 candle lantern. While it doesn’t exactly scream “weather station”, the form factor makes sense – plenty of room for electronics, easily replaced windows, and a nice cupola for mounting extra displays. [Richard]’s build includes a barometer, a hygrometer, and a thermometer, along with graphing displays for trends and historical data. There’s also an alarm clock and a rear panel bristling with more connectors and switches than an 80s-era HP oscilloscope. The wiring is admittedly “rats-nest style”, but as you can see in the video after the break, it works pretty well and looks good too.

There was a time when getting weather conditions was only as timely or as local as the six o’clock news from the nearest big-city TV station. Monitoring the weather now is much more granular thanks to the proliferation of personal weather stations. For the ultimate in personalized weather, though, you might want to build your own solar powered weather station.
It looks like [Brian Masney] went all out in designing his weather station. It supports a full stack of sensors – wind speed and direction, rain, temperature, pressure, and dew point. About the only other parameters not supported (yet) are solar radiation, UV, and soil moisture and temperature. The design looks friendly enough that adding those sensors should be a snap – if fact, the 3D models in his GitHub repo suggest that he’s already working on soil sensors. The wind and rain sensor boom is an off-the-shelf unit from Sparkfun, and the temperature and pressure sensors are housed in a very professional 3D printed screen enclosure. All the sensors talk to a Raspberry Pi living in a (hopefully) waterproof enclosure topped with a solar panel for charging the stations batteries. All in all it’s a comprehensive build; you can check out the conditions at [Brian]’s place on Weather Underground.
Weather stations are popular around these parts, as witnessed by this reverse-engineered sensor suite or even this squirrel-logic based station.
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.
