This wall hanging would look great even if it did no more than light up. But thanks to a unique controller it’s meant to work as an interactive display for your living area.
The rectangles and votive candle cups are a set of three store-bought hangings. But lighting the candles and remembering to blow them out was a pain, so [Adiel Fernandez] decided to add the LEDs to make the job easier. But why stop at that, in addition to an RGB light for each cup he made them fully addressable. It’s all the better for a light show, but this also opens up the arena for all manner of different uses.
Accompanying the wall installation is a palm-sized cube meant to sit on the coffee table. Whichever side of the cube us up sets the function for the display, with a rotation tweaking the function, and a fast spin used as a select. If the power icon is on the side facing up, a fast spin will turn the display on or off. There are also functions for weather, temperature, transportation (we were thinking something like a bus schedule notifier but it’s actually a bit different) and animation patterns. After the break you can watch a demo of the cube functionality.

This project takes an umbrella stand and gives it the ability to let you know if you need to take an umbrella when you leave the house. The image above is a concept drawing, but a first prototype was built and seems to work quite well. See for yourself in the video after the break.
The project was put together by openPicus. They sell a prototyping module called the Flyport which provides a WiFi connection to your projects. This board connects to a set of LEDs which are used to illuminate the translucent plastic umbrella stand. But you might not notice the color change if the LEDs were always on. Also designed into the system is a PIR motion sensor. When you walk toward the door to leave for the day it switches on the appropriate color — green for clear, blue for raining, and red for storming — catching your attention in time to grab an umbrella as you pass by.
You don’t need to spend a bundle to pull off a hack like this. You can scavenge for a PIR sensor, use one color of LEDs just to tell you when rain or storms are forecast, and an ENC28J60 is a cheap and easy Ethernet alternative to using WiFi.

Most home weather displays use an LED screen or other moderately interesting methods of showing you what’s going on outside. The [Tempescope], however, takes an entirely different route, actually recreating a tiny weather environment on your bookshelf!
This active weather device is controlled via an Arduino as well as a pump, ultrasound diffuser, and other assorted components connected to a computer. It was originally meant to display, or more accurately recreate (precreate?) tomorrow’s weather. What is even more interesting is that using [World Weather] software, it’s able to simulate the weather on any place on earth.
Early in this article [Ken] lists the art of [bonsai] as one of his inspirations. He’s open to suggestions as to how to expand this device, which can be seen after the break. We (I at least) would think it was awesome if there was actually a bonsai tree in the environment in keeping with its influences. Certainly our readers can give him some feedback as well!

The apartment [Angus] lives in must be sealed up pretty tight. It was so humid during the winter that there was a mold issue. We usually have the opposite problem, needing to add humidity to the air in the colder months. To combat the issue he bought a small dehumidifier, but wanted to automate the system a bit more than what was built into its meager controls. He combined a set of wireless sensors and remote control outlets to switch the dehumidifier automatically.
The sensors are from a weather station he bought on eBay. It came with a base station and three remote units, all of which monitor both temperature and humidity. He wanted a system that could compare temperature with dew point and make decisions based on a simple look-up table. An Arduino with a custom milled shield reads these measurements from the sensors and feeds them to a router which is running a cron job script every minute. When that script judges the time and weather conditions warrant a change it tells the Arduino to switch the wireless outlet to which the dehumidifier is connected.
This is [Pierre Cauchois’] digital weather display. Since weather displays are ubiquitous in this day of smart phones in every pocket he went out of his way to give it a unique look. He started with a wooden voltmeter case, swapping the ancient display for a modern LCD screen.
He used Gadgeteer components for the retrofit. The images for the LCD are stored on an SD card and displayed on demand. Since the digital bezel will be the same no matter what the time or environmental conditions [Pierre] used the power of the .NET framework that drives the system. He made up an image using magenta for all of the dial openings. This way a sprite can be used just for the changing numbers, weather icon, and graphing area.
Looking at all that went into coding the project we think the Gadgeteer components are perfect for those that are well-versed in upper-level languages and don’t really want to deal with low-level microcontroller issues.
If you’re a big Minecraft fan, the folks at [radikaldesign] have something that might be of interest to you. (Translation) Inspired by some of their Minecraft-loving friends, they have developed Minestation – a weather station for your Minecraft game.
The concept is simple. Here in the real world we have the ability to look out the window and see what it is like outside, but many of us turn to digital weather stations, the Weather Channel, or the local news to get the real scoop. They decided that the world of Minecraft should be no different, so they constructed an Arduino shield that allows players to see weather conditions as they play.
The shield contains a Nokia 6100 LCD screen which displays all sorts of useful information. It features a clock and calendar that reflect in-game time, making it easy to know when night is going to fall. It also continually displays the player’s coordinates as well as what the weather looks like in that region. Having this information at hand when you’ve been slogging away in the mines (losing track of time and weather) seems like it could be pretty useful at times.
You can buy one of the devices at Minestation.me, but the design is completely open, so you can easily construct one of your own without too much hassle.

Can you believe that [hpux735] pulled this satellite weather image down from one of the National Oceanic and Atmospheric Administration’s weather satellites using home equipment? It turns out that they’ve got three weather satellites in low earth orbit that pass overhead a few times a day. If you’ve got some homebrew hardware and post processing chops you can grab your own images from these weather satellites.
The first step is data acquisition. [hpux735] used a software defined radio receiver that he built from a kit. This makes us think back to the software-radio project that [Jeri Ellsworth] built using an FPGA–could that be adapted for this purpose? But we digress. To record the incoming data a Mac program called DSP Radio was used. Once you do capture an audio sample, you’ll need something to turn it into an image. It just so happens there’s a program specifically for weather image decoding called WXtoImg, and another which runs under Linux called WXAPT. Throw in a little post processing, Robert’s your mother’s brother, and you’ve got the image seen above.
[Hpux735] mentioned that he’s working on a post about the antenna he built for the project and has future plans for an automated system where he’ll have a webpage that always shows the most current image. We’re looking forward hearing about that.
