7 brushless pumps for a fountain controlled by Arduino Micro

via Arduino Blog

fountain
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.

Experiencing the solar flux with an interactive installation

via Arduino Blog

IMG_67962

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.

Control your Christmas lights with sms and Arduino Yún

via Arduino Blog

arduinoLightsxmas

December is finally here and we can start thinking about indoor or outdoor decorations for the holiday. Christmas lights are an excellent way to light up any event and a user on instructables wanted to be able to control the lights remotely with text messages.

Check his 12-step tutorial  and take a look at the bill of materials:

  • An Arduino Yún – You could use another Arduino with a Wifi Shield though.
  • A Protoshield with (or without) a tiny breadboard
  • A regular breadboard will work as well, but will be less compact.
    If you want to solder more, you can just use a small circuit board instead.
  • A 5V relay
  • A piezo buzzer
  • Wires
  • A battery operated Christmas decoration (It’s not even Thanksgiving, so I’m using a Halloween decoration)
  • A Temboo account
  • A Twilio account

Earthquakes reinterpreted by the human body become art

via Arduino Blog

simograph0

“Earth Partitions” installation by artist Melik Ohanian was exhibited at the Centre d’Art Contemporain à Sète in France and it’s composed by two synchronized videos with a dancer and a seismogram, the second being “written” by the first.

The dancer with two controllers in the hands was asked to “translate” into corporal expression and movements what he saw in a seismogram of an earthquake . His movements were consequently “translated back” to a seismogram using a device. Both the mime and the seismograph were filmed at the same time and both were then broadcasted simultaneously on two different screens during the exhibition.

sismograph

The project was made thanks to the work of Out of Pluto, a multidisciplinary startup working on the research and development of new technologies to materialize various projects and ideas and decided to share with us some more info about this installation.

sismmicro

Arthur and Mathias, founders of the startup, submitted the project to this blog describing me how they used two Arduino boards:

The Arduino Micro reads the accelerometer values, computes a global value and sends it via bluetooth to the computer. The computer reads this value, computes an angle according to a configurable ratio (sensitivity) and sends a new value to the Arduino Uno. The Arduino Uno sends the angle to the servo motor that rotates to this angle and then come back to 0 (if no other value is sent). Coming back to 0 simulates the end of the “earthquake”. The mechanical part of the arm is flexible so there is some inertia involved, creating the typical outline of seismograms. There is a simple motor to pull the paper at a constant speed.

Take a look at the video:

Global emotional light with Arduino

via Arduino Blog

luz

Based on open source technology and programming, LUZ is a lighting project that product designer Marina Mellado designed and targeted to those people who are physically and psychologically affected by the lack of sun or daylight.

Luz is a one meter diameter ring of light. It connects two LED stripes RGB SMD5050 to an Adafruit TCS34725 sensor ( which I use to get the temperature of colour (K) and the light intensity (Lux) Values ) and an Arduino Uno.

The electronic system is programmed to modify gradually the light-color sensibility of the lamp depending on the weather conditions when the sensor is positioned by the window.

Check the video below to see the lamp in action:

The perfect teal, new Arduino silk color and graphics

via Arduino Blog

ArduinoUnoNew

Last year Massimo Banzi wrote a long post on this blog to explain the genealogy of Arduino.  He described how an open-hardware project, designed to lower the barriers to prototyping interactive projects, was able to find its way into economical sustainability and still keep innovating.

He clearly explained what an original Arduino is, and why its cost is a matter of maintaining an open-source ecosystem, and not only of manufacturing and distributing the boards.

He detailed out what ‘counterfeit Arduinos’ are, and why they are harmful to the whole open-source hardware movement. We release Arduino’s hardware design files so that people could make their own versions, but this doesn’t mean manufacturing boards only for profit and pretending to be Arduino.

 We don’t release any element of the Arduino brand identity (logo and graphics of the boards), so whoever uses the trademarked Arduino graphics makes a deliberate act of Trademark infringement and prevent us in our effort to guarantee the quality of our products, always replaceable if defective.

We also created a page on our website showing how to spot a counterfeit Arduino.

As you can see at the link, we recently upgraded the page with new pictures as we are entering a new phase: we are redesigning the PCB silkscreens of all Arduino boards, in production in the next few months. As you might imagine, this is going to be a long process as it cannot happen in one night. The new silk will be better counterfeit-proof, and will allow you to recognise an original Arduino just by a quick look.

ArduinoUno-TOPsmall3 ArduinoUno-BOTTOMsmall2

As you can see in the images above (click on the images for hi-res), we changed some graphic elements of the board and also switched to a different shade of teal.

In the next months we will upgrade the pictures of the boards in the product pages of the Arduino website as they roll out and are distributed around the world. It’s a transitioning phase so stay tuned for more news on the blog!

Make your cat behave when you are away using Arduino

via Arduino Blog

catprotector

The goal of this project was to create a small device, which detects movement in protected areas (e.g. tables) and allows you to speak usual phrases in your voice to the cat to control its behaviour when you are away. It’s called Cat Protector and prototyped on Arduino Uno  by Lucky Resistor, a creative guy who enjoys software development and electrical engineering:

I started with a prototype, using an Arduino Uno and a large breadboard. The first step was to realize an acceptable sound output. To realize this I added a shield with SD card adapter and wrote some optimized code to stream sound from the SD card in 22.1kHz using a 12bit DAC. The amplification to a speaker completed this part of the project where I have two solutions. Next I experimented with different motion sensors to detect the motion of the cat and finished the hardware part using a dual color LED for a simple status display.

Creating a compact device from the prototype was the next challenge, I could place the whole circuit I used on a small prototyping area and squeezed everything in a small casing. From outside, the device looks simple and tidy.

catprotec

He documented everything in details on his website, especially the software part:

I read so many Arduino related articles and tutorials, but most of them stop when the prototype is running. I hope this documentation helps people to see how to structure Arduino software to make it extensible and keep it readable. This is especially necessary to write more complex logic than just to blink some LEDs. Also I hope to give some inspiration how to develop the prototype to a final device.
