Why the NSA Can’t Listen to His Mixtape – Interview with David Huerta

Wednesday, July 30th, 2014

mixtape1

David Huerta is a technologist who recently published a provocative work to make everyone think a little bit more about privacy and what governments should be allowed to do or not:

I work outside the Pokemon business model of catching every user’s data or abusing it for state surveillance. I work instead surrounded by priceless art and in giving it a voice inside and outside the thick, Faraday cage walls of the museum it lives in.

He created an encrypted mixtape and sent it to NSA. The device runs on Arduino and other open hardware and for David is a:

machinery that can be trusted not to spy on you because of the disclosure of its design, schematics and bill of materials to anyone who wishes to inspect, build, or build upon the device. The device contains a soundtrack for the modern surveillance state. It’s designed to be enjoyed only by people I have consented it to be listened to. A second copy of this device will also be sent to the NSA’s headquarters in Maryland, but without the private key needed to decrypt it; a reminder that the rules of mathematics are more powerful than the rules of even the most powerful states.

We got in touch with him and was happy to answer a couple of questions for the blog: (more…)

Two steampunk espresso machines running on Arduino Mega

vidastech on taste.kr

There’s a team of designers based in Korea who are passionate about coffee machines. Their name is Vidastech and recently shared with us two new hand-assembled machines prototyped  with Arduino Mega called Hexagon and Revolucion.

roboticHand

Marco Pucci shared on our Facebook Page a link to the tutorial he made for a low-cost Robotic Hand able to mirror the movement of our own hand. He created it  in the laboratory of new technology of Accademia di Belle Arti di Brera (“Academy of fine arts of Brera”), a state-run public academy in Milan, Italy.

The Sensing Umbrella is the second project I’m featuring on this blog (see the first), coming out of the class at  the Copenhagen Institute of Interaction Design called Connected Objects, with Massimo Banzi and Giorgio Olivero.  (more…)

DIY Pulsoximeter developed with two Arduino

Tuesday, July 15th, 2014

pulseoximeter

Pulse oximetry is a non-invasive method for monitoring if a patient’s oxygenation is unstable and Arduino user die_Diode sent us his version of a DIY Pulsoximter developed with two Arduino:

Arduino Mega for the oximetry electronics and Arduino Uno for the graph.
The electronics includes LED Driver, Photo current transformation, patient-dependent calibration LED, Active filters, Nellcor SpO2 sensor. Adafruit OLED displays Vitalparamter. Noritake VFD display GUU-100 shows the PPG. The boards are connected to the electronics with a Protoshield.

Spraying natural fibers to build cotton-candy surfaces

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.

candyproject-jin

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

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…)
