Spraying natural fibers to build cotton-candy surfaces

Monday, July 14th, 2014

candyproject06

During Fab10- Fab Festival in Barcelona I met Jin Shihui who introduced me to CandyProject, a research project exploring the process of spraying natural fiber to create a non-woven textile that can be used to produce anything from building components to ornamental artifacts.

By means of air pressure we separate the fibers from a roving allowing them to self-organize and reassemble due to the surface tension caused by a fine mist of adhesive. This creates a controlled fibrous aggregation producing an emergent morphospace encompassing the initial substructure.

The robot Jin is holding in her hands in the picture above uses air pressure to separate fibers into individual strands. While the fibers are still separated they are embedded with an adhesive spray and all parameters are controlled within the robot  with an Arduino Uno: (more…)

A breathing plant installation creating unusual sensations

uncanny - breathing plant

Arduino community on Gplus is pretty active and many people share their experiments, projects and prototypes to receive comments and tips. Yongho Jeong from Seul (South Korea) published a video called Uncanny, a breathing plant installation creating unusual sensations and made with Arduino Uno + air pump:

The uncanny (German: Das Unheimliche, “the opposite of what is familiar”) is a Freudian concept of an instance where something can be both familiar yet alien at the same time, resulting in a feeling of it being uncomfortably strange.  //
The subject of this project is interaction between human and plant. My First thought is that Do plants breathe like we human do? I was amazed after learning that plants breathe and that their breathing is very similar to ours. So I want to show that plants breaths llike human do and reacting to touch of human.

A DIY water-saving device for your house or makerspace

Wednesday, July 9th, 2014

augmentedWater.jpg

Last June Thomas Amberg participated to Water Hackathon – Open Source Technologies for Rivers, Oceans and Lakes taking place in Lausanne. He came up with a DIY solution made with Arduino Uno and a flow sensor to help monitor how much water a tub consumes.

The Augmented Water device helps you save water by turning red after one Liter and helping you not to waste it unnecessarily.
The ingredients you need to reach the results are the following: an Arduino Uno, Adafruit Neopixels, Flow sensor, LiPo battery, LiPo charger, jumper wires, tube fitting the sensor, plastic test tube and some zip ties. You can easily make one in 6 steps with his tutorial on Instructables.

The world knows what you did last summer

Tuesday, July 8th, 2014

i know what you did last summer
Jaap de Maat shared with us his final year project called I know what you did last summer, the finale to a two-year-long MA in Information Experience Design of the Royal College of Art. The ingredients are  simple (an old electric wheel chair, an Arduino Mega, 12v motor board, Bluetooth slave, wires, blood sweat and tears) and the concept is very actual:

It is physically impossible for the human brain to remember every event from our past in full detail. The default setting is to forget and our memories are constructed based on our current values. In the digital age it has become easier to look back with great accuracy. But this development contains hidden dangers, as those stored recollections can easily be misinterpreted and manipulated. That sobering thought should rule our online behaviour, because the traces we leave behind now will follow us around for ever.

Node.js on the Arduino Yún via the Bridge library

Monday, July 7th, 2014

ArduinoYun

Tom Igoe some days ago wrote an interesting post about Arduino Yún on his blog.  We post it here as it could be useful to the Arduino Community.

————————–

Recently, Federico Fissore added node.js to the package repository for the Arduino Yún. Here’s how you get node to communicate with the Arduino processor on the Yún via the Bridge library.

To do this, you’ll need an Arduino Yún, a microSD card, a microUSB cable and a wifi connection. You should be familiar with the basics of the Arduino Yún and node.js in order to get the most out of this post.

All of the code for this post can be found on my GitHub repository. (more…)

The Funky Chicken

Thursday, July 3rd, 2014

Funky Chicken
The Funky Chicken was created during a series of workshops that were given as part of the larger project “Interactive Sensory Objects Designed for and by People with Learning Disabilities”:

It was designed by Rumena, a student from the Reading College LLD/D course (people with learning disabilities) who attended the workshops on a regular basis. She made the papier mache chicken, painted it and added the frills and ornaments, and wanted it to sit inside a basket but flap it’s wings and cluck. We helped her to complete this artwork by adding the necessary electronics including an Arduino Uno, Adafruit Waveshield, speaker and a servo to make the wings flap.

The whole flapping/clucking of the chicken is triggered using a sonar attached to Arduino Uno. Moving within 1m of the chicken will trigger it:

 In the image below the sonar is hooked up to the Arduino Uno, and the Arduino is connected to the servo controller (not shown). The sonar is a very inexpensive off-the-shelf HC-SR04, which has a range of about 3m.

Here’s the video with the chicken at work:

Two new little tools for your tinkering time with Arduino

Monday, June 30th, 2014

Two new Arduino products are available starting today from the Arduino Store. Read below for details!

Arduino USB Host Shield

ArduinoHostShield

This shield allows you to connect devices to your Arduino using a USB port, for example game controllers, digital cameras, phones, keyboards, etc:

- it is based on the MAX3421E, which is a USB peripheral/host controller containing the digital logic and analog circuitry necessary to implement a full-speed USB peripheral or a full-/low-speed host compliant to USB specification rev 2.0.

- it can be used with the “USB Host Library for Arduino” hosted by Oleg Mazurov and Alexei Glushchenko from circuits@home, Kristian Lauszus and Andrew Kroll on GitHub (click to download zip).

If you want to see how to use it, take a look at this tutorial from Officine Arduino which used it to add wireless to an RC Car.

ArduinoISP

ArduinoISP

It’s a tiny AVR-ISP (in-system programmer) based on David Mellis’ project FabISP and useful to anyone needing more space on the Arduino board. Uploading a sketch with an external programmer can be used for three main reasons:

- remove the bootloader and use the extra space for your sketch

- burn the bootloader on your Arduino, so you can recover it if you accidentally corrupt the bootloader.

- when you use a new ATmega microcontroller in your Arduino, and you need the bootloader in order to upload a sketch in the usual way.

For more details about using the Arduino ISP please visit the Getting Started page

Learn how to program an ATtiny and to read your Arduino built-in EEPROM using ArduinoISP in the tutorials on Scuola.

Internet of things with Arduino Yún and Yaler

Saturday, June 28th, 2014

ArduinoYun and Yaler

Explore this tutorial  demonstrating how the Arduino Yún can be controlled from anywhere with any internet connected web browser. The solution is provided by Bo Peterson using the Yaler service which means that the Yún can be reached from any network without knowing the IP-address, and without any port forwarding on the router where the Yún is connected.

A common problem in home automation and internet of things applications is that it is difficult to reach devices connected behind wifi routers from the outside. There are different approaches to overcome this problem:

  • Port forwarding and static ip addresses. This solution requires the user of the connected device to know how to configure a router and have access to router administration which is not always possible. A Yun tutorial with port forwarding is found here.
  • Polling is a technique where the connected device at regular intervals checks with an external server if the device should take action. This solution requires no configuration of the router but it creates extra network traffic and response delays.
  • A third way is to use WebSockets which is a way of providing real time full-duplex communication over TCP. Spacebrew is a good open source toolkit for connected devices using WebSockets. Autobahn is another infrastructure that can be used.
  • Reverse HTTP is the solution that will be used in this tutorial. We will use Yaler which is an open source relay infrastructure that gives access to connected devices with very little configuration.
