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. (more…)
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.
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…)
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.
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.
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.
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.
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:
