Visualizing air quality with interactive origami flowers

Monday, September 28th, 2015


“Under the Dome – PMgami” is an installation created by designer Jiayu  Lui using Arduino Nano. Inspired by paper origami techniques, the digitally fabricated flowers move and change color according to the quality of air measured locally. The main aim of the installation is to obtain a more intuitive way to communicate pollution data and  the relationship between technology and nature.

In the gallery you can explore some other pictures and the schematic. Check the video below to see the installation in action! (more…)

Smile! This plant wants to take a selfie with you

Monday, June 22nd, 2015


The Selfie Plant is an interactive installation taking pictures of itself using Arduino Yún, Facebook Graph APIs and then uploads them to Facebook. It was developed by a group of students at the Copenhagen Institute of Interaction Design during “The secret life of objects” course held also by team by Joshua Noble and Simone Rebaudengo. The final prototype was on display at the class exhibition, to observe the interaction of the audience with it, and the results are on Facebook.

Build a Touchscreen Controlled Marionette with Intel Galileo

Saturday, February 14th, 2015


Making gets really interesting and fun especially when mixing laser cut shapes, servo motor, tft screen, MDF, plexiglass and Intel Galileo Gen 2. After you assemble the parts and follow the steps of this tutorial, you’ll be able to control the puppet through an interface on the screen. Enjoy the tutorial!

We are going to have a little fun with the Intel® Galileo development board. This time around, we’ll make a simple puppet control system. We’ve put together a “running robot” marionette with a simple mechanism that uses a continuous servo. We’ll be use a touchscreen interface to control various outputs using sliders and switches.

As always, you can modify the designs to suit your needs. We will teach you how to incorporate touchscreens, and make the interface necessary for controlling the Intel® Galileo Gen 2 board.

Just so you know, the instructions this time around are quite long. That’s due to the assembly of the marionette. I would review the assembly instructions fully before attempting to put it together. While it looks long and complicated, if you group the parts, it much simpler.

So, let’s start the puppet show!

Arduino powered Lucky Cat as physical webcounter

Thursday, November 15th, 2012

Rebuilt my lucky cat: whenever a page of my website is loaded, the cat will be waving its arm. There’s a light sensor so when its dark, the cats RGB-LED is changing the color instead of waving the arm. Changing the color of the LED is also possible with one of the buttons on the cats ears. The other one is the reset button. Used an arduino ethernet, a servo, two buttons, an RGB LED and two small yellow LEDs. The seven segment display is one that I harvested from an old stereo. It’s driven by the arduino and two shift registers. unfortunately I’ve soldered that one together for an older project, so that it doesn’t fit into the cat too. It shows the number of pageviews of the website.

An open robot shield for Arduino

Monday, August 6th, 2012

Open Electronics‘ staff were looking for a common and standard hardware platform usable on different robots they were working on. Their goal was to find a single platform that had to provide power supply to the microcontroller, it had to provide stabilized voltage for the servos, and, finally, it had to be equipped with an obstacle detector and with an IR receiver.

Having chosen Arduino as the target core board, they developed an ad-hoc shield meeting all these requirements, whose detailed description can be found here, together with the BOM and a lot of source code.

Vertical Plotter Prototype

Monday, July 30th, 2012

Nice Grasshopper-to-Arduino plotter hack from FablabTorino maker Pietro Leoni, a collabotator at Carlo Ratti Associati studio in Turin. We’d love to see code & sketches online soon, as much as a second edition of the plotter.


Some advances in aerial vehicles: bat-inspired smart wings

Wednesday, June 6th, 2012

Researchers from Centro de Automática y Robótica (Universidad Politécnica de Madrid) and from Brown University carried out a very deep research about the specific behavior of bat flight, whose ultimate goal is to replicate the capabilities of bat’s wings by means of an ad-hoc designed micro aerial vehicle (MAV).

From the home page of the project:

[...] this research is oriented towards the development of a biological inspired bat robot platform, that allows to reproduce the amazing maneuverability of these flying mammals. The highly maneuverability is achieved by reproducing the flapping and morphing capabilities of their wing-skeleton structure. This structure is composed by several joints and a membrane that generates the required lift forces to fly.

To mimmic the muscular system that moves the joints of the wing-bones, Shape Memory Alloys (SMA) NiTi wires are used as artificial-muscles. Several challenges in controlling this SMA-based actuation system are regarded in this research.


DIY Radio Control

Monday, May 14th, 2012

Going to buy a new Wireless Controller for your next Robotics project. Why buy a new one when you can Do-It-Yourself? All you need is an Arduino, an old Joystick with a Gameport (15-pin connector) and a pair of Series 1 xBee Modules.

The explanation of the xBee Configuration and the xBee Packet Description is very well done at the blog.

Transmitter: Joystick + xBee [No additional hardware needed]
Receiver: xBee + Arduino + [your amazing Robot, Car or a Plane!]



Directional shoes for the blind

Le-chal from Anirudh's presentation

Sometimes, it is amazing to see how technology is used to make the world a better place to live for the less fortunate. One such problem has been thought out and tackled by Anirudh Sharma aka touchaddict on IRC. His invention is called ‘Le-chal’ which translates to ‘Take me there’ in Hindi.

Sharma conceptualized and demonstrated the system at MIT (Massachusetts Institute of Technology) Media Lab Design and Innovation Workshop 2011.

The Le Chal system comprises of a pair of shoes, one of which is fitted with Vibrators, proximity sensors and a Bluetooth pad which is connected to an Android phone that calculates directions and real time location using Google Maps and the phone’s built-in GPS and compass module.

For all the people calling Arduino a ‘toy’ and ‘too simple’ here is a fact: it’s simplicity gave the inventors the power to rapidly prototype, and the invention was ready in 6 days.

As per his presentation, the system costs barely a few hundred rupees to assemble with 8 mini vibrational motors costing Rs 90, a sole of specified dimensions, an Arduino Lilypad GSM+GPS shield custom made for Rs 400 or a wired version costing Rs 150 for all the components.

The shoes have also been tested at a blind school in Bangalore, India, and have received positive reviews.

Build Your Own Undersea Robot

Thursday, September 1st, 2011

David Schneider from [IEEEspectrum] tells and shares his DIY Remotely Operated Vehicle undersea, based on two Arduinos

Last year at about this time, crews in the Gulf of Mexico were working feverishly to bring BP’s blown-out oil well under control. Some of the more spectacular parts of that effort, as you may recall, involved the use of remotely operated vehicles, or ROVs. Perhaps you had the same thought as I did—that it would be cool to build one.

And shares all the instructions to build your own [.zip].
