Chad Herbert’s son Daniel was diagnosed with Benign Rolandic Epilepsy in 2014. It’s a type of epilepsy the Epilepsy Foundation says accounts for about 15 percent of all Epilepsies in children and the good news is that most children grow out of it.
The bad news is that Daniel’s most affected by his condition at night or early morning while he sleeps. That’s why Chad invested in a sleep monitor/alarm for his bed that detects when he’s having a full tonic-clonic seizure. (more…)
Every year the students of the Copenhagen Institute of Interaction Design (CIID) attend the Physical Computing class as part of their curriculum.
Having a small delegation of the Arduino team teaching this class has become quite a ritual. This past March Ubi De Feo, Alice Pintus, and Lorenzo Romagnoli runned the two-weeks-long intensive class.
Teaching at CIID is great experience, since you are surrounded by incredibly motivated and curious students, that are doing everything possible to design amazing projects and prototypes.
The topic of this year was prototyping interactive installations for a Science Center that would explain in a playful and engaging way how a technology works. For most of the students this was the first experience with physical computing, but even in such short time they were able to build eight different prototypes. The projects explain in an interactive way the science behind computer viruses, allergies, video compression, machine learning, laser printing, digital music synthesis, binary numbers and neuroprosthetic.

After 13 years, Classe Virtuale project is once again an interesting opportunity for students to experiment a bridge between school and work. “Classe Virtuale” is a partnership between Loccioni and technical educational institutions started in 2001 when the group started offering to young students training periods and internships in the company giving the chance to work on a real project together with very skilled people and technicians. In 2012 they worked on a flow meter and this year the project focused on a similar project called People Meter, using Arduino Uno, wi-fi and rfid modules, and a 3d printer.
Below you can find more information (in italian) about the team, the project and the results!
Patrick Griffin is a maintenance technician working in the plastics industry for the last 20+ years with primary focus being the repair, upkeep, & design of electrical, electronic, automation, and both relay & PLC control logic. He submitted his project to Arduino blog about using Teensy Arduino on a Maac vacuum former:
This story revolves around one of the workhorse machines in the company where I work: a Maac vacuum former. It is a solid, well-designed machine with a solid, well-designed control system that Maac contracted out to the Electro Cam systems group. As with any industrial equipment, as time goes by the OEM develops new products that replace their old stuff, technologies advance, and eventually they start the formal process of obsoleting their older inventory.

The Mood Lamp project by Vittorio Cuculo, is a system using interactions to communicate an emotional state to a physical object and receive back a coherent response. In particular, through your facial expression you communicate your emotional state to an RGB color lamp . The lamp, at this point, will respond to the interaction by changing the color of the light emitted in accordance with the emotional state inferred.
The aim of the systems is to remove the mediation between human and machine typical of classic interfaces. Among the modes of natural interaction we usually have gestures, gaze tracking and facial expressions. The latter are particularly relevant because they play a fundamental role in nonverbal communication between human beings.
Regarding the man-machine interaction, the ability to recognize and synthesize facial expressions allows the machine to gain more communication skills, on the one hand by interpreting the emotions on the face of a subject, and on the other by translating their communicative intent through an output, such as movement, sound response or color change.
An IKEA lamp becomes a Natural Interaction system which senses human emotional states through facial expression. It uses OpenCV for image processing and analysis to identify emotional state through the movements of face’s fiducial points. The lamp, made with an Arduino Duemilanove, changes its color to represent the user’s current emotion.
In particular, it receives via serial communication, the values of pleasure, arousal and dominance, following the PAD emotional state model, as inferred from the facial expression and changes accordingly the color of the RGB LEDs.
Ever wondered about the extent of diversity in electronics? Been to a theatre and wondered at the sophistication of the live stage set? Welcome to the world of theatrical electronics. An exclusive inteview with this engineer in Arts – Ben Peoples
Priya: What is theatrical electronics? I always thought that theatres bought standard stuff off the shelves.
Ben: Theatrical electonics is a field of science where we try to rapid prototype electronic items on the stage to make things appear more real. Of course, it is a huge field. With 25 different theatres around the place where I live, my plates are generally full!
P: Interesting! How long have you been associated with electronics to capture such prototyping skills? What are the general tools that you use?
B: I have been prototyping electronics for over 20 years. I have been an ardent user of Arduino for the past 6. I loved the community so much that I even teach it to other people.
P: Oh teach too? Like classes for theatre prototyping? I would like more details on that.
B: (Smiles) Well not much, they are just getting started on how to rapidly put things together and program it using an Arduino to give it an “appearence” of more complex stuff like Time machine on stage.
P: Sounds fun. What are the theatre-specific whacky things that you teach them to build in the workshop? What are the general tools needed to attend your class?
B: I teach them to build Reed-candles, an elevator, wireless fireplace, wireless-dimmer, using Xbee radios for the lighting console and more things like that. I typically teach them inside a theatre wherein they need to bring their own laptops and software. They are seated inside a rehersal space so that they get the exact feel of designing things for a theatre. Other than that, its the usual arduino boards, gear motors, LEDs and of course, loads and loads of scotch tape! (Laughs)
P: Woah! How long does it take for you to teach them these?
B: 2-3 hours to teach math and the basics, 5 hours to explain the basic expriments and seeing them prototype their first objects. So yes, in total, 8 hours.
P: What according to you, is the advantage to pick electronic skill in the field of theatre?
B: There is theatre in colleges, the person could rise up to be a technical director, there is huge demand for lighting design, scenery design and of course in this age of television and movies, every drama theatre wants to stand out and do something extra. I see a huge future for it!
P: Okay one question that intrigues me after all this conversation is how different is theatre electronics from electronic arts?
B: Interesting question! For starters, Electronic Arts is very finished and polished. Theatrical electronics is well.. more raw and duct-taped at the back. They are two entirely different industries.
P: What are the things that interest you other than prototyping and what would be your ideal birthday present?
B: I love Ariel photography. Ideal birthday present is anything photography related. For work, I have to shoot digital, but for art I shoot 100% film, and just love it.
P: Any advice for youngsters?
B: Don’t be afraid to try anything new. Ship early, ship often.
One of the best capabilities provided by Arduino regards its very high modularity, which helps users to quickly translate ideas into physical artifact, as practically demonstrated by Mauro, which shows on his blog how to build a simple data-logger by properly combining different shields. By using few additional components (mainly resistors and buttons) a fully-functional data logger can be easily implemented.

Ecco un piccolo video report della puntata dell’Arduinotour a Matera (c’é anche un set su Flickr). Questa edizione del tour é stata caratterizzata dalla partecipazione di un ragazzo francese (partito dalla Bretagna e volato per un week-end a Matera – Grande Baptiste!) che ha condiviso con noi la sua esprienza di sviluppatore di open energy monitor, un framework open source per la visualizzazione di consumi online, di cui parleremo presto in una intervista ad hoc. (il blog di Arduino ha trattato precedentemente questa storia, vai al post).
Causa maltempo il workshop é stato ospitato presso le Monacelle, un bed & breakfast poco l’ontano dall’Incubatore, all’interno dei Sassi. Un grazie a Sviluppo Basilicata per il supporto e l’aiuto nell’organizzazione dell’evento.
Per chi si stesse chiedendo quando e dove si farà il prossimo workshop #arduinotour, eccovi serviti: Reggio Emilia a fine gennaio (26-27), presso il neonato Fablab ospitato all’interno dello Spazio Gerra.
