IKEA Cloud Lamp Displays The Weather With An ESP8266

June 12, 2019 by 5 Comments

The IKEA DRÖMSYN is a wall mounted cloud night light that’s perfect for a kid’s room. For $10 USD, it’s just begging for somebody to cram some electronics in there and make it do something cool. Luckily for us, [Jodgson] decided to take on the challenge and turned this once simple lamp into a clever weather display. It even still works as an LED lamp, if you’re into that sort of thing.

After stripping out the original hardware, [Jodgson] installed a Wemos D1 Mini and a string of fourteen SK6812 RGB LEDs that run down the length of the cloud’s internal structure. Weather data is pulled down with the OpenWeatherMap API, and conditions are displayed through various lighting colors and effects.

Sunny days are represented with a nice yellow glow, and a cloudy forecast looks like…well it’s already a white cloud so that one’s pretty easy. If rain is expected the cloud turns blue and the bottom LEDs flicker a bit to represent raindrops. When there’s a thunderstorm, the cloud will intermittently flash random LEDs on the strip a bit brighter than their peers; a really slick effect that gets the point across immediately.

This isn’t the first time we’ve seen somebody take a cheap light from IKEA and turn it into something much more impressive with the ESP8266. Just like with that previous project, we wouldn’t be surprised to see this particular modification popping up more in the future.

A Contact Lens Launcher That Knows The Weather

April 7, 2019 by 10 Comments

They say that necessity is the “Mother of Invention”, but over the years we’ve started to suspect that her cousin might be an underutilized microcontroller. How else can you explain projects like the latest from [MNMakerMan], which takes the relatively simple concept of a contact lens holder and manages to turn it into an Internet-connected electronic appliance? Not that we’re complaining, of course.

He started out with a simple 3D printed holder for his wall that would let him pull out his daily lenses, which worked well enough and gained some popularity on Thingiverse. But he wondered if there wasn’t some way he could use a servo to automate the process. While he was at it, he might as well play with some of the components he’s been meaning to get some hands-on experience with, such as those little OLED displays all the cool kids are using.

Modifying his original design to incorporate servos in the bottom, he added a central compartment that would house an ESP8266 and a simple proximity sensor made from an IR LED and photodiode. The sensor tends to be a little twitchy, so he left a potentiometer inside the device so he can fine tune it as needed.

Strictly speaking the OLED display isn’t actually required for this project, but since he had a WiFi capable microcontroller sitting there doing basically nothing all day anyway, he added in a feature that shows the weather forecast. It’s not much of a stretch to say that the first thing you’d want to see in the morning after regaining the sense of sight is a readout of what the day’s weather will be, so we think it’s a fairly logical extension of the core functionality. Bonus points if he eventually adds in a notification to remind him it’s time to order more lenses when the dispenser starts getting low.

If you don’t have any contact lenses you need dispensed, never fear. A similar concept can be used to fire off your customized swag at hacker events. Don’t have any of that either? Well in that case you can always build a candy dispenser for Halloween.

Checking The Weather Without A Window

April 27, 2018 by 9 Comments

Making a weather display is great because it’s a simple project that shows off some skills and has an obvious daily use. So [ACROBOTIC Industries] decided to make an easy kit for the Hackaday Prize to make weather displays even more accessible.

Calling it the ESPecter, [ACROBOTIC Industries] wanted to make this a simple project for anyone, regardless of skill with a soldering iron or Arduino toolkit. So they decided to base the guts on common components that can be put together easily, specifically a Wemos Mini D1 with an OLED shield as a bright display. They also designed a cool tiltable 3D-printed enclosure for this small device so that you can orient it to your eye level.

ESPecter breadboarded prototype.

While they already have a breadboarded prototype, and a 3D printed case, some software work remains to make the project really shine. They plan to add nice features like a web interface to configure location and network information, alerts, additional locations, and historical weather data. They also want to create a weather library to display well on a low-resolution screen and add battery operation.

We look forward to seeing the final version later in the Hackaday Prize!

This isn’t the first weather project we’ve seen around here. Other variants include mirror weather displays, an ESP8266-based weather monitoring station, a very low-power weather station, and this roundup of weather displays which might give you some inspiration.

Magic Mirror On The Wall, “Is Pi Or ESP, Fairest Of All?”

December 30, 2015 by 23 Comments

“What’s the weather like, honey?” “I don’t know. Let me check the mirror.”  The mirror?

Both [Dylan Pierce] and [Dani Eichorn] have mirror projects that display the weather. They took two different approaches which makes for an interesting comparison. [Dylan] uses a Rapsberry Pi with an actual monitor behind the mirror. [Dani] puts an OLED behind the mirror driven by a ESP8266.  It appears there is more than one way to hack a mirror, or anything, which is what makes hacking fun.

Raspberry Pi Booting
Framing Mirror and Monitor

[Dani] started with a picture frame, adding tinting film to the glass so it would reflect. A small section of tint was removed to allow the OLED to be seen. The ESP8266 software connects to the Weather Underground to get the latest information.

The Raspberry Pi version by [Dylan] puts a 27″ monitor behind the mirror. That is either terribly impressive or way over the top but seeing Linux boot behind the mirror makes it worth the effort. The Pi generates a web page which makes this adaptable as a general purpose kiosk.

PiClock – Time And Weather Information Overload

June 10, 2015 by 48 Comments

[Kevin] wanted a display where he could take a quick glance and get all the current environmental information he uses throughout the day. That information includes, of course, the time and date as well as weather information. We’re not just talking the current weather information but the forecast for the upcoming week as well as a map showing current weather patterns. To do this, [Kevin] came up with a unique system he’s calling the PiClock.

[Kevin] did some serious programming to get this clock project off of the ground. The weather data comes via the Weather Underground API and the map data from the Google Maps API. The main program is written in Python and will run on any OS running Python 2.7+ and PyQt4. If you’re interested in doing something similar, check out the source at github.

From the project’s name, it is no surprise that a Raspberry Pi is the brains here. A USB WiFi adapter allows access to the internet but an Ethernet connection would do just fine. Having the RaspPi hanging out with wires everywhere would be a little lazy, so [Kevin] opened up his 19″ LCD monitor and mounted the RaspPi inside the case. He tapped 5vdc off of the monitors power supply and used that to power the RaspPi, no external wall wart necessary! And if the PiClock’s background isn’t cool enough, some RGB LED strips were mounted to the back of the monitor to give an Ambilight effect.

Hacklet 49 – Weather Display Projects

May 30, 2015 by 2 Comments

Everyone wants to know what the weather is, and what it is going to be. Today’s internet enabled forecasts give us continuous streams of current weather data and predictions from any of several computer models. Couple that with data from an on-site station, and you’ve got a lot of information to display! It makes sense that weather display projects would be popular with hackers, makers and engineers. What do you do after you build the worlds most awesome clock? Build the worlds most awesome weather display (and then incorporate a clock in there as well!).

Last week on The Hacklet I mentioned that there are two basic types  of weather projects on Hackaday.io: Sensing and Display projects. There was a bit of foreshadowing there, as this week’s Hacklet covers some of the best weather display projects on Hackaday.io!

geoWe start with [Ashley Hennefer] and G.E.O, a project which is out of this world – literally. Geological Environment Observer, or G.E.O was created for NASA’s Space Apps Challenge. G.E.O’s mission is to keep astronauts on long-distance space flight missions connected with their home city (and planet). An astronaut programs the device with their home city and G.E.O takes it from there. Inside a glass globe, G.E.O creates weather patterns mirroring the programmed city. It does this with Adafruit NeoPixel LEDs, a water pump, a mist generator, and a wave shield. An Intel Edison controls the system. For now, weather data and programming are completed using a web interface. Once G.E.O launches though, data will be streamed via NASA’s deep space network.

flaps[Sephen DeVos] keeps track of the weather with a glance at his Internet Split Flap Weather Clock. Lots of weather apps use simple icons to display the current conditions. [Sephen] placed those icons on a mechanical split flap display which lets him know the conditions outside. The project’s case came from a donor clock given to [Sephen] by his parents. He then 3D printed an entire split flap mechanism, including the gears! Each 50 mm x 100 mm flap forms half an image.  A small stepper drives the flaps, while an IR detector lets the system know when it has reached a home position. Control is handled by an Arduino Nano and companion Ethernet shield. The Arduino checks the weather every 30 minutes. If conditions have changed, it flips to the right icon. Genius!

usmap[Dan Fein] is keeping track of the temperature across the entire USA with Weather Map. [Dan] works for Weather Underground, so it’s no surprise that he uses their API (accessed via a node.js script) for weather data. The data is fed into a spark core which then drives a string of 100 WS2812 LEDs. Each LED is mapped to a specific point in the continental USA. Color indicates the current temperature at that location. [Dan] does caution that you’ll have to slow down access to Weather Underground  if you’re using a free API key. Even with slower updates, this is still an awesome project!

yaws[Jeff Thomas] went the traditional route with YAWS – (Yet Another Weather Station). YAWS uses a 5 inch TFT LCD to display weather data from a number of sensors. [Jeff] got his display and the driver board from buydisplay.com. The driver board uses the venerable RA8875 display driver chip. The RA8875 handles all the hard parts of driving an LCD, like video RAM, refresh, and clocks. This allows a relatively slow Arduino to drive all those pixels. [Jeff] created a very handsome interface to display all his data, but he has a small problem – a memory leak causes the system to freeze up every 18 hours! We’re hoping [Jeff] will share his source code so the Hackaday.io community can help him find that pesky bug!

If you want to see more projects like these, check the Weather Display Projects list on Hackaday.io. That’s it for this week’s Hacklet, As always, see you next week. Same hack time, same hack channel, bringing you the best of Hackaday.io!

Hacked Kobo Becomes A Weather Display

October 21, 2012 by 26 Comments

The Kobo e-reader has been hacked for a while now. It’s pretty easy to enable telnet access by modifying some files. Once [Kevin] was able to telnet into the device and draw to the display, he created the Kobo Wifi Weather Forecast. This hack was inspired by the Kindle weather display that we discussed in the past, but this version runs entirely on the Kobo.

The weather report software is written in Python using the pygame library. After loading the software package onto a Kobo, a few commands are run over telnet to set up Python and run the display. Since Python and pygame run on the Kobo, it allows for direct access to the e-ink display.

There’s a lot of possibilities for a internet connected e-ink device running custom graphics code. It’s asking to be turned into any kind of display you can imagine. What ideas do you have for a custom e-ink display? Let us know in the comments.
