7 brushless pumps for a fountain controlled by Arduino Micro


Using Arduino Micro to control a fountain is the project shared by Michael Diesing on Twitter:

May I introduce my second ARDUINO-project with own pcb. With the pcb I am able to drive seven brushless pumps(with integrated electronics). The “problem” with such kind of pumps is that they don’t accept unfiltered pwm-signals as supply voltage. So I created a circuit where the pwm-signals of an ARDUINO-micro are level-shifted to 12V with a darlington array and afterwards filtered with a 1 uF ceramic capacitor and a 730 Ohm resistor (low pass filter). The signals are then led into the adjust-pins of seven “lm317″s. To work properly I needed to connect the adjust-pins also with 2500 Ohm resistors to gnd, but I found out that with two l293d instead of the used TDP62783 (darlington array) these resistors are not needed, but different resistor and capacitor values for adequate filtering!
The pums also have tacho signals which I connected via schottky-diodes to the ARDUINO (inputs with pullup). With the tacho-signals I am able to find out if pumps are stuck, are sucking air or are not connected.
Additionally I added one ACS712-05B current sensor (which measures the entire current of the circuit) that could be used to find out if pumps that don’t have tacho-signals are working properly. At the moment it is not used.
Besides that I integrated a lm386 audio-amp used to amplify the signal of an electret-mic to a level that is suitable for the ATEMGA’s ADC.

As the first project for the pcb I created a fountain consisting of a shortened wine barrel, seven brushless pumps, a pushbutton with led and pebbles (s. video).
There are seven animation-modes which can be selected via the pushbutton (the selected mode is stored in eeprom).
The speed of the pumps is checked permanently during operation.
The average power consumption is ~20W and max. consumption is 30W.

Handy Arduino makes it on french television

Last saturday, Arte tvl aired a short documentary in french language about Arduino. The video was created by FUTURE magazine and featuring Massimo Banzi, David Cuartielles and Arduino users: children and young electronics enthusiasts:

Tinkering in a garage on a drone, playing with a set of lights with LEDs or even build a robotic arm worthy of a science fiction movie … Today, even when one is a novice in electronics all this is possible through Arduino, a real flexible technology.

They also created two nice short info-animations to explain what is Arduino and the idea of open source:

Arduino TRE Developer Edition, 2nd round of beta-testing

30 Arduino TRE Developer Edition boards (the last ones!) are available online today on our store. Whoever purchases them will be added to our Beta-testing Program, joining the about hundred betatesters already contributing to the development of the hardware and software of the board. You can learn about the program and the board on this post.

These boards have the latest Web IDE pre-installed and ready to go, we are now at a stable IDE release with everything fully functional. We will write a specific post about the new Web IDE next week, so stay tuned!

The first round of the program focused mostly on hardware and software testing, and we have just rewarded the betatesters who contributed the most. We really would like this second round to revolve around contents creation. For all Arduino boards, examples and projects are really crucial to get beginners started with a new environment. This is even more relevant for the Arduino TRE, that thanks to the onboard Linux system, has so much more power and potential than classic Arduinos.

For instance you could use the Arduino TRE as a personal cloud, keeping all your data available to your connected devices without having to rely on third party services; you could create a system to stream music wirelessly to your speakers with a tangible user interface; build a DIGI software that allows ZigBee porting; make an interactive whiteboard for schools, and so on.

We have a reward system in place for completed projects: two coupons of the same value of the Arduino TRE Developer Edition purchased, a dedicated post on our blog, Arduino TRE limited edition T-shirts, 10% off coupons for the Arduino Store. We look forward to hear about your projects!

When is the Arduino TRE going to be finally on the market? The board is ready, but we don’t have a final release date yet because we are still figuring out some manufacturing matters. We’ll keep you posted!

Experiencing the solar flux with an interactive installation

Dmitry Morozov shared with us a new interactive installation called  Solarman at the Polytech Museum in Moscow. 2014 and It’s a work he created with Julia Borovaya and Edward Rakhmanov using 64 ultra bright LEDs, 12-channel sound system and 8 electrical nerve stimulation electrodes controlled by Arduino Mega :

Data on power of X-radiation flux from the Sun is received in real time from the satellite GOES15 which is tracking solar activity. It is being converted into streams of sound, light and electric discharges, thus allowing a spectator to experience in more intensive and evident way the influence of the main luminary of the solar system.

The data, which is measured in watts per square meter, come with a frequency of once per minute. A special computer algorithm transforms it in sound waves, distributed by 12 channels in the space. The radiation power directly controls the height of tones and spectral changes in the sound. The speed of sound displacement in the space is also dependent on these parameters. Light is generated by algorithmic transformation of X-ray emission into physical modeling of light particles, which also affect the muscle stimulators in the chair to produce weak electric discharges.

Casa Jasmina: a New Domestic Italian Landscape (NEW WEBSITE!)

 

Last October at Maker Faire Rome, Massimo Banzi, Bruce Sterling and Lorenzo Romagnoli announced a new exciting project.
The project, called Casa Jasmina, is a real Apartment in Turin, hosted by Toolbox Coworking in a old industrial building already shared by Officine Arduino (the Italian Arduino headquarter), and Fablab Torino.

The apartment will serve as test bed for the latest development from the open source community. We will explore the boundaries in the field of open source connected home showcasing the best of open source furnitures, connected objects, and white goods hacks.

Shortly anyone will have the opportunity to experience living in a open source connected home, Casa Jasmina will be available for rent on Airbnb.

Do you want to collaborate with us or propose your ideas? Please check the partnership opportunities and get in touch! hashtag #CasaJasmina

Today we are launching the official online presence of the project and to celebrate the kickoff of Casa Jasmina website, we are happy to share Bruce Sterling thoughts on the project.

A New Domestic Italian Landscape

A lot has already been said about the Internet of Things, so the time has come to attempt to live the dream.

As a science fiction writer and design critic, I’m all for speculation. However, the IoT is no longer a theory. It features genuine industrial consortia, proliferating standards, and exciting new capacities in sensors, data, and analytics. The Internet of Things is coming into the home, and that most definitely includes the Italian home.

So, how will that happen? It seems there are five basic approaches.

  1. THING CENTERED. In this model, every object has its own Internet connectivity and they all talk to each other independently. It’s like the old-school Internet, but with things instead of websites.
  2. GATEWAY CENTERED. There’s a home control box or a router which serves as a boss for all the anarchic things, enforces a standard on them, and protects them from security attacks.
  3. MOBILE CENTERED. The real action inside in the operating system of a powerful personal smartphone, which acts as the handheld remote-control for everything.
  4. CLOUD CENTERED. The household Internet of Things is run by offshored professionals who have advanced data analytics and can manage all domestic objects and services for a fee.
  5. INDUSTRIAL FOG. Everything is run locally, but with an urban, automated factory-style model that includes building management software and Smart City services.

What’s missing in these five models of the IoT? A user-centered model, a citizen-centered model, an open-source collaborative model. That’s the prospect that interests us at “Casa Jasmina,” the Torino Fab Lab / Toolbox Co-Working domestic lab in Torino, Italy.

This design approach is what we can contribute, from Torino, to this epic world struggle — and it is epic, and it is a world struggle of great consequence to us and everyone else.

The older, customer model, where twentieth-century consumers bought their dumb appliances from simple boxes and plugged them in, is becoming extinct. A new domestic landscape is becoming visible. We want to bring that to life with the values of “Make In Italy” — rapid invention, plenty of mistakes, and results that combine innovation with elegance.

My role in Casa Jasmina is that of curator. In the blizzard of new things that constitutes the Internet of Things, I have to figure out what belongs on the premises. Casa Jasmina an actual, functional apartment directly above the lasers, routers and 3DPrinters of the famous Torino Fab Lab. It will have guests in it; people will sit in the chairs, sleep in the beds. I will personally test every last “thing” that goes in there.

Our first piece of household furniture is already chosen: it’s “Pietro Micca,” our pet Roomba robotic vacuum cleaner. I chose this vacuum cleaner as our mascot, not because it’s “high tech,” but because the Roomba line is ten years old, well-established, a living reality of domestic home automation. “Pietro Micca” will be martyred, because we are going to hack him relentlessly, but he represents “normal life.” That’s what we want to see and display in Casa Jasmina — the “normal life” of about ten years from now.

 Soon, as Casa Jasmina’s curator, I will be “accessing” many other objects and services. We are looking for sponsors, advisors, experimenters, and developers. Let me be quite specific. These are among the things we need.

  • A terrace garden. This is an Italian home and we want living things to grow, flower, and thrive there.
  • A study area including a bookshelf, effective task lighting, and cultural materials reflecting our Make in Italy values.
  • Artworks including electronic art displays.
  • A guide to Torino for our many foreign friends. How does an Internet-of-Things home properly display the city that surrounds it?
  • A functional kitchen. Being Turinese, we naturally favor Slow Food that is good, clean and fair.
  • Children’s toys and furniture. How does an Internet-of-Things home respond to small, innocent people who are not its power-users and don’t interact with its controls? Children are participants in home life and any proper home design takes their needs into account.
  • Temperature control, water control, electricity monitors, building-management services.
  • Household appliances.
  • Party supplies. A congenial home of the future must stand ready to entertain!
