Arduino a Robotica 2012

Wednesday, November 7th, 2012

 

Anche quest’anno Arduino partecipa a Robotica – mentre non partecipa Makersitaly! – e ha scelto il mezzo della stampante termica in controtendenza con i mille volantini, flyer, cataloghi, allegati, biglietti da visita e tutta la montagna di carta che avrete nelle tasche alla fine dei tre giorni – giovedì venerdì e sabato – della manifestazione.

Siamo ad Impatto Zero, quindi non esageriamo neppure con la carta!

Journalism #2 Typewriter: generative stories about killed journalists

Wednesday, May 30th, 2012

“On Journalism #2 Typewriter” is a typewriter installation of Julian Koschwitz, which purpouse is to remember journalists who got killed in the past 20 years. The installation writes generative stories about all journalist who have been killed worldwide between 1992 and today based on the existing data on their life as well as their published work. The individual stories are connected through common fields of coverage, places, professions and the story is written endlessly on one endless piece of paper.Besides the text the typewriter creates flags which are distorted the more journalists got killed in that particular country.
The installation makes use of Arduino Nano, Arduino and Processing software, 32 solenoids and shift-registers.

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.

Block Diagram

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

TicTocTrac: track your perception of time

Monday, May 14th, 2012

TicTocTrac Wristwatch

Brian Schiffer and Sima Mitra, from Cornell University, propose a very nice wristwatch that allows you to keep track of your time perception, using a method known as duration production: TicTocTrac.

Human perception of time is typically distorted, due to the different amount of information and experiences acquired everyday. TicTocTrac lets you to estimate your own perception, first by signaling the perceived duration of a given event and, then, by comparing it with the actual event duration. Finally, all the information can easily be saved to a micro SD card.

The hardware is based on a Atmega32u4, a DS3234S real-time clock and several leds to display time, while the software part is mostly based on Arduino’s DS3234S RTC library.

Gardening + Arduino = Garduino!

Monday, May 7th, 2012

There are many available projects for the automated irrigation and lighting of plants using the Arduino board.

 

For those who were not already aware, here is the link to a tutorial by Instructables published a few days ago.

And here an old but useful article written by Luke Iseman on Make Volume 18.

The Botanicalls crew had created a leaf-shaped electronic board that allows transmission via Twitter of your plant conditions.

 

It ‘s time to seed!

 

Android app to control arduino

Monday, February 20th, 2012

This new android app in the the market enables you to communicate to your arduino using an WYSIWYG kind of interface using a bluetooth shield.

Features:

– discover and connect to Arduino board with Bluetooth shield
– display board firmware version, name and Firmata protocol version
– set pin mode (analog/digital input/output, pwm)
– get/set pin values
– LED and pin mode animation
– read messages from the board (Firmata String Sysex message)
– beautiful WYSIWYG interface with 320×480, 480×800, 480×854, 1024×600 and 1280×800(?) screens support
– no special sketches required (only slightly modified StandardFirmata sketch from Arduino IDE examples bundle)
– Free, no ads

The further details can be read here.

Christmas lights E-mail notifier

Tuesday, December 20th, 2011

So you are busy this Christmas day, and are one of those people who have been dragged away from their laptops.

Fear not, you’ll know the exact number of emails even while you are away from your laptop.

The guys over at Make have decided to guide you through the whole experience. In the example, they use an Arduino board hooked up to the internet using an ethernet connection, but there’s no reason it can’t work wirelessly – you just need the right board.

Its a simple-to-build exciting festive project!

Hooked up to the web, a bit of code on your mail server and the board itself allow the Ardunio to count your unread emails. If the number’s changed, it throws a signal to a power switch which controls the AC power connected to your lights.

Voila! When you get a new message, your Christmas lights let you know.

Blackberry Playbook and Arduino

Tuesday, December 6th, 2011

 

Adding just a few conditions in a small program, and using Arduino integrated with sensors, we get to add intelligence to a BlackBerry Playbook application.

The Arduino board uses an IR range sensor to find targets. The IR sensor is placed on a servo to scan the area of interest (e.g. kitchen). The data is sent to the BlackBerry PlayBook tablet, on which we’ve built an application to present a sonar map and look for movement. If movement is detected, the application will sound an alarm and take a picture.

Talk about hardware hacking!

Marcus with his hack

We all dream of a technology matching the Jetsons someday. And there came Siri, so close to a personal assistant to a gadget-lover. Here is Siri taken to the next level by Marcus Schappi, who dreams of using it to automate his home next.

An Australian man has become one of the first to hack the iPhone 4S voice recognition app Siri but his motives were not sinister – he wants to use the smartphone as a home automation tool.

He joins another Sydney developer and founder of Remember the Milk – a task manager app for the iPhone, iPad and Android platforms – in hacking Siri.

Mr Schappi says his hack could allow users to do simple tasks such as turn their air conditioning on or off, control their home entertainment or alarm system and unlock their front door or car.

But the hack may not last long, with Mr Schappi predicting Apple would want to close the hole he exploited.

To understand how the hack works one must know a bit about how Siri operates. It sends “voice packets” to Apple’s servers. The tech giant’s computer servers then provide voice recognition on these packets and returns a string of text.

To cap it all, it does not involve the jailbreaking of the iPhone!
Mr Schappi described the set-up as “relatively inexpensive”. It uses what is known as an Arduino board with an Ethernet port ($69.95), at least two Arduino compatible relay modules or electronic switches ($13.50 each) and one wireless mains remote ($24.95), bringing the total to $121.90.
Mr Schappi is the director of Little Bird Company, an electronics ’boutique’ as he puts it.
