A traditional weather house gets a smart upgrade

Friday, August 7th, 2015

wetterhaus

The “Enchanted Cottage” is a project by Andy Clark with the aim of upgrading a traditional  german “wetter haus”  with a new mechanism and electronics running on Arduino Yún:

The mechanics were replaced with a servo and 3D printed parts designed to make the movement linear rather than arcing as in the traditional approach. The figures were fitted with magnets so that they could move without any obvious form of propulsion.
The electronics were based on an Arduino Yún, custom prototyping shield and an Infineon RGB LED driver shield. The whole thing is powered by a rechargable LiPo battery and a module from AdaFruit. Because the Arduino was deep in the middle of the house, I used fibre optics to bring the light to the top panel. A sensor was added into the roof so you could simply tap it to get it to update the forecast for you.

The project was build over a period of 16 weeks, the mechanical aspects were completed first and the 3D printing took several goes to get it right. The electronics build was fairly straightforward but fitting everything onto the proto shield was challenging and the high clearance for the Yún was also a challenge. The software was written as I went along with demo programs created to test each part. Getting the Yún to work on low power was fairly straightforward but getting a secure and validated HTTPS connection took a few attempts. tried to put as much of the processing into the Python script so that the C++ code was just handling the control. All in all a challenging project that pushed the Yún to it’s limits.

Build an IoT Gauge with Arduino Yún and IFTTT

Wednesday, August 5th, 2015

gauge

Tomas Amberg shared with us the link to an Instructable he published on how to build a Web-enabled, Arduino-based IoT Gauge with a REST API, and connect it to the IFTTT mash-up platform, via the Yaler.net relay service he founded.

The cool thing about this project is the connection with the Maker Channel  of IFTTT which supports custom Webhooks, to integrate DIY IoT projects:  (more…)

If you feel like experimenting with connected objects, a good idea could be to start from a funny project explained step-by-step in a tutorial. In the video below you can follow the instructions given by Dana, Documentation Hero at relayr, using an Arduino Yún, a gas sensor and relayr cloud to make a little Batman-shaped toy dance according to data: (more…)

Smile! This plant wants to take a selfie with you

plant_post

The Selfie Plant is an interactive installation taking pictures of itself using Arduino Yún, Facebook Graph APIs and then uploads them to Facebook. It was developed by a group of students at the Copenhagen Institute of Interaction Design during “The secret life of objects” course held also by Arduino.cc team by Joshua Noble and Simone Rebaudengo. The final prototype was on display at the class exhibition, to observe the interaction of the audience with it, and the results are on Facebook.

Building a quadcopter running on Arduino Yún

Monday, June 8th, 2015

Comelicottero

Comelicottero is a quadcopter based on Arduino Yún created during the Master in Computer Science at the Universita’ degli Studi of Milan (Italy) by Simone Castellani, Giovanni Intorre and Andrea Toscano:

The idea was to build a drone able to be controlled through WiFi from any PC, tablet or smartphone . Comelicottero is equipped with an accelerometer and a gyroscope for the stability obtained by a PID-based control system. Since Servo library is too slow for the quadcopter dynamics, an hardware PWM was implemented to obtain a 400Hz PWM signal.

The communication between the ground station on a PC and the quadcopter relies on WiFi and, in order to get better results, Bridge library was replaced with an efficient python script on OpenWRT-Yun. On top of that all the code was written to maximise Arduino Yún capabilities. The Navigation System has been designed, simulated on PC, implemented and tested. The autonomous navigation is going through an additional testing due to magnetometer interferences with motors’ magnetic field. (more…)

Wire Your Arduino Sensors to the Cloud with Temboo Streaming

Our friends at Temboo just introduced a new way to log data from an Arduino Yún to the cloud. Called Streaming, it lets you visually select the sensors attached to your Arduino that you have gathering data, and then stream that data to the cloud IoT platform of your choice. (more…)

Build Arduino-based IoT apps with Temboo Conditions features

conditions-temboo

Last week Temboo just added new Conditions features to its IoT Mode interface, making it even easier to connect your Arduino to the Internet of Things! Now, the functionality of Temboo’s Device Coder has been extended to all 2000+ Choreos in the Temboo Library, meaning that data collected from sensors attached to an Arduino Yún can be used to trigger any cloud process, and responses from the cloud can be used to trigger all sorts of hardware actions on your board.
