Ardupower

Friday, November 16th, 2012

It’s a power stip driven remotely through an Ethernet network using telnet protocol.
The password and tcp parameters are saved in eeprom.
The user can give names to the six power out, that are also stored in eeprom.

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.

APDuino Project – Custom Monitoring without Coding

Thursday, November 15th, 2012


 
[srejbi] shares a new, programming-free, API-based way to programming Arduino: the APDuino project (minimum hw requirements: Arduino Mega 2560 + W5100 EtherShield). The Apduino relates to a peculiar approach towards Arduino that I noticed in the last years: using Arduino and making things without coding. This is a good thing for people that can’t code, but has to be simpler than learning code itself.

The APDuino Project provides a turn-key software solution for building custom monitoring and automation systems with custom rulesets (featuring expression evaluator with access to sensor and control arrays), cron-like scheduler, remote access and management via HTTP, SD and online logging and more…

All *without* programming (if using supported hardware components) … allowing DIY’ers to build their own automation systems much quicker and easier.

— The image collage attached is showing parts of 1 realization I built (I have 4 completely different systems running, all using the same software :)) — This one pictures an aquaponics monitoring system with 16 physical sensors (lots of 1-wire DS18B20’s chained, DHT-11, photoresistors, HY-SRF05 with mechanically inverted reading surface providing tank level monitoring, radio-controlled sockets allow pump and fan controls).

Other systems feature components such as vibration detector, pH probe, BMP085,DS1307 RTC.

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.

More information can be found here.

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.
