A hovering object that explores and manipulates transitional public spaces with particular acoustic properties. By constantly recording and replaying these ambient sounds, the levitating sphere produces a delayed echo of human activity.
The bike bag is made from umbrella material to make it waterproof, and I made it with safety features using the Lilypad light sensor and LEDs. My husband always forgets his reflectors but with the bikebag always being on the bike, he’ll have no excuse not to be a safe cyclist!

I use a micro, but just about anything will do. There’s some Sugru on there to keep the sharp bits from catching on clothing/pockets. Usb battery powers the whole thing. It’s pretty bright, definitely not subtle.
Spacebrew is “an open, dynamically re-routable software toolkit for choreographing interactive spaces”, basically a way to connect smart objects of any kind using the WebSocket protocol.
Basically, they modified the Arduino WebsocketClient library to use it with Intel Galileo and specifically with Spacebrew:
The received situation was of a version of the Arduino WebsocketClient library: https://github.com/labatrockwell/ArduinoWebsocketClient (oriented to Spacebrew) adapted from: https://github.com/krohling/ArduinoWebsocketClient (implementing the online websocket protocol) neither of them supporting Galileo, an Intel SoC Pentium-based board. It has been revised, modified, and integrated, so that this version runs on Galileo and works for both the connection to a server such as echo.websocket.org and Spacebrew. This version includes extended tracing facilities for debugging (see WebSocketClient.h). The main changes with respect to the previous versions are marked by slash-slash-star-slash-slash.
You can explore the library on Github.
Holger from Fablab Düsseldorf writes in about a small robot they prototyped with Arduino Uno, helping them raise some funds for their local space:
We created the idea in our non-commerical FabLab in Düsseldorf, Germany to create a small robot, who makes our vistors and guests aware of placing a small money donation. This robot was required to be transportable, robust and to draw as much attention as possible.
Thus, we included LED-Stripes, servos, sensors and sound to the project. Packed in a very old german vacuum cleaner. The work took about 1 year to construct, print and integrate all 3D-printed parts, wiring and software development with the Arduino Uno. But software development was the minor part, although parallel processing on the Arduino in order to run every component simultaneously required a small trick.
These are the components in action:
- Controller: Arduino Uno R3
- Software: Standard Processing and standard libraries
- Audio: VLSI VS1000 Audio Module incl. our own firmware that lets the Arduino control the board
- Distancesensor: HC-SR04 embedded in a modelled nose of FIMO
- 4 LED stripes (2 RGB on the backside)
- 6 power-LEDs for the top
- 1 servo for moving the top
- 1 Servo for moving the bill-mouth
- 3 distance sensors for bill and coin detection
- 1 switch for muting the audio module and 1 reset button
A few years ago Sven and Juho started working on the same type of project without knowing about each other and only by a coincidence their paths crossed. They wrote me about their cool story and the successful experiment of upgrading a diesel engine using Arduino Mega:
There’s a prettty large community out there in the car/motorsports hobbyist world that loves their vehicle but the engine is getting old, worn out and maybe even too bad to renovate. What people do is to take the engine from a newer car with a modern direct injected diesel engine, with all the cables, sensors and motor controller (the ECU) and adapt it to their beloved old car. This is exactly what is going on with the VW buses (called vanagons in the US) where the diesel engines from the beginning is a bit on the small side and 20 years later their performance is not much better than a garden tractor. A “new” electronically controlled engine is used to replace the old worn out engine, and with that follows better power, less pollution and way better fuel economy.
BUT, this takes time and is a complex project. You have to adapt the cablage, install the ECU (the motor controller) and must be sure that all the peripheral sensors sitting all around the engine is brought over to the new car and is working. You might also have to adapt the instrument cluster behind the steering wheel to make all the warning lights and gauges to work again.
The idea with the Arduino controller is to take the ENGINE ONLY and then let the Arduino manage the engine with the sensors that is on the engine itself. By doing this, the motor swap is reduced to a weekend project and everything in the bus is working as it was before. No instruments modification, no need for external valves and sensors, no adapted cablage. Just the Arduino.
You can find the whole documentations and the details of the project on Juho’s website.
John Thomson managed to build a pressure sensor to behave like a switch, when it’s in an idle state the LED is off, if you apply some pressure, light goes on:
The pressure pad doesn’t just work straight out the box – it requires a little bit of craft. What I’ve done is sandwich a pressure sensitive conductive sheet – known as Velostat – between two pieces of felt. I then stitched some conductive thread through each piece of felt – this applies a current to the pad and when the sandwich is put together, the circuit is complete. The Velostat acts like a resistor – the value changes when pressure is applied. It’s then just a case of writing out code that tells the LED to come on when the pressure reading goes over a certain threshold.
“You can’t touch this” is the project submitted by Stefano Guglielmetti for the Connected Home Project Contest by Make Magazine. It’s composed by a movement sensor (PIR) plus a camera and an Arduino Yún. When the sensor perceive a movement, Arduino plays a sound, takes a picture and sends you an email:
The purpose is clear. You don’t want your kids to steal your food from the cupboard, or from the fridge, or someone to open your locket, or you want to take pictures to your pet stealing food, or you are Dwight Schrute and you want to finally unmask the coworker that puts your stuff into jelly… so you hide the device into the cupboard/fridge/locket, and when the device detects some movement, it will take a picture and post it right to your email! And if you use IFTTT, then you can automatically post the picture of the thief to Facebook, Twitter and show the thief’s face to the entire world!
The project is very simple, it doesn’t require any soldering/electronics skills and it can be assembled in minutes.
L‘Arduino Tour torna nel 2014 con due tappe ’on the beach‘: Rimini e Pula. Le due location ospiteranno nelle prossime settimane due workshop dedicati all’alfabeto di Arduino e alle wearable technologies.
- L’appuntamento di Rimini si terrà sabato 22 febbraio negli spazi del nuovissimo MakerRn Lab di Rimini, dove Zoe Romano e Riccardo Marchesi di Plug&Wear introdurranno in otto ore di workshop il mondo dei wearables. Nella prima parte della giornata ci si avvicinerà a livello teorico alle applicazioni wearable, mentre nella seconda i parteciperanno produrranno un piccolo progetto con un sensore tessile. Appassionati di moda, design e smanettoni sono benvenuti, non è infatti richiesta alcuna conoscenza di programmazione o di taglio e cucito. Qui trovi i dettagli per prenotare uno degli ultimi posti ancora disponibili!
- La tappa sarda dell’Arduino Tour toccherà mercoledì 26 febbraio la sede dello IED di Cagliari (Viale Trento 39, h. 17) con un’introduzione alla scheda Arduino curata da Mirco Piccin e aperta a tutti. Tra giovedì 27 e venerdì 28 febbraio, il team Arduino si sposterà invece con Davide Gomba a Pula negli spazi del Parco Tecnologico della Sardegna, dove il Fablab di Sardegna Ricerche ospiterà le 16 ore di workshop vero e proprio. Al termine del percorso, i partecipanti avranno per competenze per mettere a punto mini-progetti, da implementare poi in autonomia a casa. Prenota la tua partecipazione qui!
Kinisi by Katia Vega is a project combining FX makeup and electronic sensors. It’s prototyped using Arduino Uno and creates interactions with a smile, a wink, raising eyebrows and closing lips. As you can see in the video below, each movement of the muscles can trigger different light patterns.
Larca Meicap, a special effects makeup artist, combined her FX makeup materials with our sensors for precisely applying them on specific muscles. LEDs were also hidden on the skin and hair. Digital signals collected by the sensors are sent to a microcontroller that activates a light sequence on Kinisi’s face and hair.
I am glad the video was filmed at Aluzcine by the cinematographer Cesar Fajardo and his team, and under the direction of Juan Carlos Yanaura. Also a special music track was composed for this video by Maribel Tafur.
Steve Yoshida is a systems engineer and worked on a project involving Arduino Micro and Infrared remote adapter:
My new Arduino sat on the shelf for a few weeks before I came up with a quick project that I wanted to use it for. I use XBMC a lot on both PC and Raspberry Pi and wanted a quick way to get IR keyboard inputs from a remote. I had used the IR library for Arduino in the past so I was already pretty familiar with the hardware and code involved. What made the Arduino Micro ideal for this project was the keyboard emulation supported by the board and also its compact size…
Take a look at the complete post on his blog with more pics and the sketch.
RobotChallenge staff updated us with some numbers regarding the “Hack the Arduino Robot” competition launched at the end of January and sponsored by RS Components. They received 58 submissions from 20 different countries of the world! 10 projects were then selected by an international Jury composed by David Cuartielles (Arduino), David Tarrant (RS Components, Design Spark), Karim Jafarmadar (INNOC) and Pavel Petrovic (Robotika.sk).
Now it’s time for the second phase. They are going to receive an Arduino Robot each, implement the project they submitted and publish the results (including a short video) by the 23rd of February.
The 10 projects selected are the following:
- OFF RObot / John Rees
“I plan to design and 3D-print different legs for the robot, so that it can be placed in a dock and the rotation of the wheels can enable it to ‘walk’. The primary goal would be to design and print a spider-legs (octopod) or beetle-legs (hexapod) attachment, enabling the robot able to travel on uneven surfaces such as grass. After this has been tested and is functional I would like to add sensors to the legs to enable me to design optimal walking attachments with maximal efficiency, as well as explore the use sensors on the feet to measure things such as such as moisture/temperature/rigidity of the surface and potentially adjust the walk cycle to suit the conditions.”
- An under floor doctor / Naoki Fujihara
“My proposal is using an Arduino robot as an extermination of harmful insects machine for house. In Japan, there are white ants or rats under floor of houses . These under floor sometimes unsanitary but workers have to into there and exterminate them. I want to solve this real life problem. My idea is mounting on some items on an Arduino robot as follows: a camera for catching situation in real-time and a function to put pest poison or traps on a appropriate place. And some sensors that can measure humidity whether the under floor condition is a room for improvement. With an Arduino robot’s smallness and mobility, this idea can be a good solution.”
- EnergyBot / Alex Shaw
“The Energy saver robot will travel round its location detecting the number of lights that are on and windows that are open and rooms that are unused, temperature, drafts, cold spots, carbon monoxide, co2 or other hazardous substances. Energybot will tweets/message to the owner to remind them to be more energy efficient and of any impending dangers. It also records data to allow the user to find out how efficient and safe each area is over time. Energybot helps to keep running costs low and automates the experience of chasing my family to shut the window!. Energybot keeps an eye on heating efficiency, average temperature, energy consumption by room and helps me to maximise the usage of my energy.”
- RoboPet / Roberto Riggio
“Pets often feel alone at home when their guardians are out for work. RoboPet is a robot companion for pets. It is able to play sounds either pre-recorder or directly streamed from the guardian smartphone. The guardian can control the robot remotely using a simple web browser or a smartphone. RoboPet is also equipped with a camera and a laser pointer to interact with the pet.”
- AWBB – ArduWellBeingBot / Florent Brodziak
“This small autonomous robot, free to move itself in a place is able to measure surrounding environment quality. It can track humidity, temperature, ambient noise and light, Air quality in the way to map and classify this place as a pleasant or nasty for humans. All the data can be consulted via internet on a map indicating the place location and a note. This robot could be used for example in public places (Mall, Railway Station , Airport, Park…) where people needs or want to stay for a moment. It will allow people to find the best place for them, for their health and it will imply more place’s responsible to improve the environment quality.”
- Eyeduino / Eduard Petrenko
“Let your Arduino robot see the world! An idea is to capture low-resolution image (estimation is 32×32 black&white) from analog camera using some kind of video sync separator like Texas Instruments LM1881 and some comparator schema. We plan to use prototype regions on the robot’s control plate to mount the schema. Modern technical vision approach requires more powerful CPU and much more memory for image processing, but for some tasks low resolution seems to be enough. We plan to demonstrate this by exercises like dotted line following and “cockroach hunting” – following some little movement changing target. We expect this approach to be an effective introduction step into technical vision in robotics.”
- Nemo / Rajan Ayyappan
“I would build a Hide and Seek Robot: We create a set of hiding places, draw lines and feed the location data into the robot. At the start of the game, you close your eyes and count up to 20. The robot will go and hide somewhere. You will start a timer on the robot as you finish 20. You have to find the robot and stop the timer within a certain period to win that round. The game makes robots look more human. It will be a teaching aid and we could add sensory experience to influence the robot in selection of hiding place. This data could be analyzed for insight into decision making process.”
- PendelBot / Dieter Schön
“The PendelBot has oversized wheels (diameter ~30-40cm), so that the Robot in between them acts as a pendulum. A battery pack underneath the motor board ensures that the center of weight is extentric. When the motors accelerate the wheels, the torque turns the chassis in the opposite direction. An acceleration sensor will limit the angle of the chassis to 90°. The robot can be remotely controlled via bluetooth by an app on an android device. This app uses yaw and pitch angles of the device to control the robots speed and direction. This setup can work as pendulum or inverted pendulum (thus posing as a mini segway(c)).”
- Battery robot / Sebastian Groza
“Arduino robot will be used as a core for a used battery collector system (robot). Robot can be mount on top of a usual battery collector container and will have a receptacle for used batteries. Arduino robot is used to sort the batteries by size, AA, AAA and others. AA and AAA batteries will be harvested for remaining power with a step-up converter. Recovered energy is used for charging a backup accumulator, power a LED banner or even charging the robot. After complete depletion, batteries are dumped in collector container along with other battery types.”
- Garment Transporter / Jacob Glueck
“A couple of years ago, I built an Arduino-powered shirt-folding machine which folds clothes. Using the Arduino robot from the RobotChallenge, I will build a device to remove folded clothes from the machine and to stack them. My idea is special because it will involve two Arduinos (the Arduino Uno in the shirt folder, and the Arduino robot) which will have to communicate, and because it will be very useful. The robot will solve the real life problem of laundry folding by making the task easier and faster and by doing so nicely; the robot will use a custom-designed gripper to transport garments while keeping them perfectly folded.”
Two projects will receive an award donated by RS Components:
- Best project & documentation Award
- Community Award.

Today’s guest blogger Vaughn Shinall from Temboo‘s team updates us with a new feature to ease your way into smart homes.
Choose your sensor, choose what action you want it to trigger, and voila–your Arduino Yún is doing it. Sending texts when a light sensor detects night, logging temperature data to a Google spreadsheet while you’re away, calling you when it sees an intruder in your home.
With our new Sketch Builder you can program your Yún to do all these things and more in no time. After choosing from multiple sensor types and actions, you can set the conditions and pins for your set up and have the code generated in an instant right on Temboo’s website. Then it’s just a simple copy-paste-upload job, and you’re on your way.
Go give the Sketch Builder a try today. Support for more sensor types and actions are on the way, so let us know what you’d like us to add.
Watch the Sketch Builder in action:
PS – You should also check out this cool Arduino Yún project where the user managed to get Temboo running straight from the board’s Linux distribution by installing the Temboo Python SDK on the Yún.
