A Proof of Concept Project for the ESP8266

via Hackaday » » hardware

weather

It’s hardly been a month since we first heard of the impossibly cheap WiFi adapter for micros, the ESP8266. Since then orders have slowly been flowing out of ports in China and onto the workbenches of tinkerers around the world. Finally, we have a working project using this module. It might only be a display to show the current weather conditions, but it’s a start, and only a hint of what this module can do.

Since the ESP8266 found its way into the storefronts of the usual distributors, a lot of effort has gone into translating the datasheets both on hackaday.io and the nurdspace wiki. The module does respond to simple AT commands, and with the right bit of code it’s possible to pull a few bits of data off of the Internet.

The code requests data from openweathermap.org and displays the current temperature, pressure, and humidity on a small TFT display. The entire thing is powered by just an Arduino, so for anyone wanting a cheap way to put an Arduino project on the Internet, there ‘ya go.

ARglove

Arduino user Jubeso submitted to our blog an instructable explaining the 10 steps to build an input device for gaming.

The  Gravity Touch bluetooth glove  is specifically designed to interact with augmented reality glasses like the Google Glass, Meta, Moverio BT or with the VR headsets like Oculus Rift, Samsung Gear VR, vrAse, Durovis Dive:

Those new products are amazing and they need new types of input devices. This instructable will describe how to build your own “Gravity Touch bluetooth glove” and I will also give you some tips to build your own Durovis Dive VR headset so that you will be able to enjoy full mobile VR. Because this glove will be of most use for VR game, I have created a Unity3D plugin for Android that handle the communication between your app and the glove. It means that you will be able to use your Gravity Touch glove to interact with your Unity3D VR game.

The Arduino code and the Java class I wrote to handle the communication between the glove and the Android device will also be available so that you will be able to adapt them for your need.

 

The bill of materials, among other things, contains an Arduino Micro , FreeIMU – an Open Hardware Framework for Orientation and Motion Sensing and 3m of flexible soft electric wire.

The internet of trees makes smart birdhouses using Arduino Yùn

via Arduino Blog

tumblr_inline_nbjvwkqaDW1rxqn91

The connected birdhouse is a project prototyped during a workshop ran by Massimo Banzi at Boisbuchet, last August in France. It was developed using Arduino Yùn, by Valentina Chinnici, who shared with us the project, and two other students taking part to  the week of learning-by-doing around the theme of  the Internet of Trees.

They redesigned a traditional object, a wooden birdhouse to be placed outdoor, and connected it to a lamp shaped like a nest, to be placed indoor:

The connected birdhouse was in fact an interactive object able to communicate to the nest/lamp the presence of a bird inside the house, and accordingly to a color coded signal was giving also some informations about the size of the bird itself. In the event of a bird entering into the house, the nest/lamp remotely controlled via WiFi by an Arduino Yùn, was turned on. The nest/lamp received the notification from the birdhouse translating it firstly with a rainbow effect. After few seconds the light changed according to the weight of the bird (green, yellow or red).

The LED strip used for the nest lamp was an Adafruit Neopixel strip controlled by an Arduino Yún.

On this blog you can find the sketch to make it work and create one yourself.

Put out a candle with the power of your mind

via Arduino Blog

Trataka

Trataka” by Alessio Chierico is an interactive installation controlled by Arduino and based on a brain-computer interface. It was exhibited at Ars Electronica last week. When a visitor totally relaxes and focuses, the candle magically extinguishes:

Trataka is a Sanskrit term which means “to look” or “to gaze” and it refers to a meditation technique. This practice consists in concentrate the attention in a small object, or more commonly in a flame. In meditation, this technique is used to stimulate the ajna chakra: a point located in correspondence of the brain. According to the Hindu tradition, this chakra is one of the six main centers of vital energy, and it is considered as the eye of the intuition and the intellect.

This installation is composed by a brain-computer interface that detect the brain waves and defines parameters like the level of attention. Wearing this device, the user is invited to concentrate his attention on a flame placed in front of him. The level of attention detected by this system, controls an air flow located under the flame: higher level corresponds with a more intense air flow. The interaction process aims to the user engagement for increase his attention in order to put the flame out. This will happen when the highest level of attention is reached: the air flow become strong enough to extinguish the flame.

via Arduino Blog

legoband

We’d like to share the performance, by Opificio Sonico,  recorded live in July 2014 of  Toa Mata Band, best known as the “World’s first LEGO robotic band” and controlled by Arduino Uno which is hooked up to a MIDI sequencer:

In this video, the third episode, the robots are playing some unconventional drum-percussions made by some food packaging are captured by a contact microphone (piezo) and processed in real time in the D.A.W. Ableton Live. A brand new device appears for the first time, it’s a moving platform on x-axis, made of Lego bricks, gears and servo motors that permits to move with semitones-steps the tiny synth. The song is a cover of the famous synth-pop band Depeche Mode, it’s a personal tribute to the band who made my days in the 80′s.

 

A bike tachometer measuring more than just speed

via Arduino Blog

diytachometer

Nikodem is a young maker  based in Poland and shared with us his latest project based on Arduino Leonardo. It’s a DIY bike tachometer providing you with a set of additional information:

It shows your speed, the average speed, the temperature, the trip time and the total distance. You can change it using the button. Additionally, the speed is shown on a tachometer. I built it because I like building new things, I have not found anything like this on the internet so I want to show you how to build a good speedometer as the one on my bike is not as cool as I want :) .

You can find all the steps to make one yourself on  his Instructable account, and in the meanwhile take a look at the two videos below.

The Maker Gene: Arduino at the Venice Biennale of Architecture

via Arduino Blog

makergene

Arduino has been chosen as an example of how the open-source, collaborative approach is reshaping the world of technology and design and, on September 5th and 6th, we’ll be on of the contributor of the Weekend Specials section of the 14th International Architecture Exhibition of la Biennale di Venezia curated by Rem Koolhaas.

The Arduino space at the Biennale Architettura 2014 has been conceived to inspire visitors to rediscover their ‘maker gene’: the impulse to learn and make things by yourself. Curated by Enrico Bassi, the exhibition includes responsive installations and hands-on demos to encourage visitors to interact and better understand the creative, transformative potential of Arduino and other open-source digital tools.

The first section focuses on the history, development and applications of Arduino. It features a glance at the evolution of the board, alongside an illustration of how it can enable an easy, direct approach to electronics and programming. In a dedicated area, the Treviso Arduino User Group, a local community of makers, engages visitors in a two-day hackathon on biometric and environmental sensors. The mezzanine level offers a playful and immersive take on what Arduino can bring to light installations.

A second section explores the impact of Arduino on a variety of innovative projects and businesses. It features a selection of items from Arduino AtHeart, a program designed to support and promote independently developed Arduino-based products: Primo, Smart Citizen Kit, Bare Conductive Touch Board, littleBits Arduino Module, and Cromatica.
In the Italian Innovators area, a special focus is granted to outstanding examples of how Arduino fosters creativity and technological development in its country of origin: WASProject, a research initiative on architectural 3d-printing; MEG, an innovative open-source home greenhouse; Light Cryptalk, an Arduino-powered recreation of the WW2 Enigma cypher machine.

Ironically extending the maker approach to other, broader parts of society, a set of videos in the final section of the exhibition compares the effects of the closed- and open-source philosophy in sectors ranging from the auto industry to architecture, suggesting the possibility of a radical, pervasive transformation.

 

The Maker Gene was produced in collaboration with: Fablab Torino, Officine Arduino, Treviso AUG, Torino AUG, MEG, WASProject, Michele Lizzit, Primo, Smart Citizen Kit, Bare Conductive Touch Board, littleBits Arduino Module, and Cromatica.

Supported by: Arduino

Arduino Tour goes to London: 21st of September – Workshop on #Iot

via Arduino Blog

arduinoPlant

Next 21st of September Arduino Tour is finally landing in London for a one-day workshop, starting at 10am at The Maker Works London, UK. (max. 18 people).

This edition of the official Arduino workshop is focused on the world of the Internet of Things and will allow participants to experiment with a botanical kit including an Arduino YÚN, plants and sensors. The workshop teaches you how to turn your plants and virtually any object into connected, responsive elements using Arduino YÚN.

Arduino YÚN is the combination of a classic Arduino Leonardo and a small Linux computer, able to connect to a network or Internet via Ethernet or WiFi. Arduino boards are able to read inputs – light on a sensor, a finger on a button, or even a Twitter message – and turn it into an output – activating a motor, turning on an LED, publishing something online.

Music and language skills get a boost with Toot

via Arduino Blog

toot02

Toot is an interactive and sound-active toy designed for children aged between 3 and 6 years old that wants to enhance their auditory, music and language skills. It was developed by Federico Lameri as his thesis project of Master of Interaction Design at Supsi and prototyped using Arduino Leonardo.

The toy is composed by eight little cubical speaker boxes:

On each speaker children are able to record a sound. In order to listen back to the recorded sound the speaker must be shaken as if the sound was physically trapped into a box. After having recorded sounds on them, the speakers can be placed in a sequence after Mr.toot, and by tapping on his head it is possible to trigger the playback of the speakers in a sequence. toot is also matched with a mobile application that offers different kind of interactions and experiences. it allows to play some exercise that will teach children to listen, understand and catalog sound and melodies.

The app expands the possibilities of interaction, offering different exercises created with the help of musicians and educators from different areas of expertise,  some of them are also inspired by a Montessori sensorial activity.

Take a look at the video interview with Montessori educator Fanny Bissa:

 

Video mixing chess games on tv in Norway using Ethernet Shield

When The Norwegian Broadcasting (NRK) planned the television broadcast of the Chess Olympiad 2014 in Tromsø, Norway, they encountered a challenge: how to mix video, graphics and the results of many ongoing chess games simultaneously, requiring 16 cameras for the games going on at the same time?

montering_i_boks-638x294

On their blog you can find a long and nice post about how they found the solution using Arduino Uno, Arduino Ethernet Shield and the library for Arduino to control such Atem switchers written by Kasper Skårhøj:

At first, the idea was to use a computer with a webcam for each of the 16 games, then mix video images, background animation and results in software on each of them.

Afterwards the finished mix of images would be streamed to separate channels in our web player, so that the online audience would be able to choose which game they wanted to follow. This solution would also provide our outside broadcasting van (OB van) with 16 finished video sources composed of video, graphics and results. This would make the complex job of mixing all video signals much easier.

After thorough thinking we came to the conclusion that for our web-audience, it would be better to skip the stream of individual games, and spend our resources on building websites that could present all games in the championship via HTML in real time. This would also give the audience the opportunity to scroll back and forth in the moves and recall all the previous games in the championship. We started working on it immediately, and you can find the result on our website nrk.no/sjakk.

An ARM-based GPS/GLONASS Tracker Board joining Arduino At Heart

via Arduino Blog

OpenTrackerTOP

We are excited to announce that OpenTracker v2 by Tigal is our new partner in the Arduino At Heart Program and ready to be backed in an Indiegogo campaign.

OpenTracker is a  fully open source commercial grade GPS/GLONASS vehicle tracker that comes with a free web interface for tracking it on Googlemaps or OpenStreetMaps.

The interface allows the tracking of a single vehicle or larger fleets simultaneously: currently it is possible to track the location, speed, altitude, heading, and address of the vehicle as well as save logs of location data for later use. With additional sensors it is also possible to track humidity, temperature and other parameters when desired.

The OpenTracker v2 is the second version of the original OpenTracker with many improved features, and a significant reduction in price.

 

 

Let’s have a look at some tech specs. The OpenTracker v2 is ready to run out-of-the-box and includes the same powerful 32-bit ATMEL SAM3A8C ARM controller as the Arduino Due, a Quectel M95 GSM/GPRS modem for wireless connectivity, a Quectel L76 GPS/GLONASS module with Assisted GPS, CAN-BUS, plenty of I/O options and a wide operating temperature range of -35°C to +80°C. The included CAN-BUS, plentiful I/O and on-board GSM/GPRS modem can be used to create many interesting applications such as CAN-BUS logger, SMS Gateway, SMS Remote Controller, and Weather Station with SMS notifications to name a few.

The OpenTracker v2 is available as a complete bundle including the Board, High-Quality Aluminum Enclosure, Power and Programming Cable as well as a GSM/GPS Antenna, or as a stand-alone board for those interested in using the board as an enhanced Arduino Due. The free online tracking interface is available at opentracker.tigal.com.

Support them on Indiegogo! (only a couple of days left but it’s flexible funding and going ahead with the manufacturing in any case!)

This page is next level of Virtual Touch Screen project. 

Technically, there are two hardware parts were added, to fully demonstrate extra ordinary sensitivity of the VTS project. First one is the BlueTooth module. And second is a tablet, running android. Device that I have, doesn’t support USB host mode (OTG), otherwise I may be fine w/o BT, just transfer a data over USB cable, as it was done in two previous demo video clips.  Have to say, it was not easy to represent 3D perspective on a flat screen, and picture below shows what I designed to complete a task:

android

Don’t think it requires a comments, the tricky part was to create an elliptical grid to show a distance. The number of circles is not limited to 2, I’d think about how to film next demo video, that ‘d show a “volume”.

Enjoy the movie:
