Arduino, GPS and Display i2C…

Friday, May 25th, 2012

 

En este nuevo tutorial Arduino by ARDUTEKA, estudiamos a fondo los módulos GPS, en concreto los módulos diseñados por LIBELIUM, para aprender a extraer y comprender todas las tramadas de datos que recibimos de los GPS y posteriormente, tratar esa información para mostrar en un display con bus i2C datos como la latitud, longitud, altura y hora UTC…

Alarma DIY con Módulo 3G, Cámara, Ultrasonidos, Teclado Matricial & Led RGB

Tuesday, May 15th, 2012

Arduteka lanza su último tutorial!

En él nos descubre el nuevo módulo 3G para Arduino de Cooking Hacks con el que podremos construir una divertida alarma que nos enviará la foto de nuestro intruso directamente a nuestro correo, además de avisarnos por un mensaje sms a nuestro teléfono móvil sin necesidad de tener conectado nuestro Arduino a internet constantemente, pues lo hace todo a través de la red móvil.

Vamos a construirnos una alarma totalmente casera, a través del sensor de ultrasonidos, escanearemos continuamente el espacio situado enfrente suyo con un radio aproximado de 30º, cuando algún objeto o persona se sitúe en su campo de actuación a una distancia inferior a la que establezcamos, haremos sonar una alarma, tomaremos una fotografía, el Led RGB que antes estaba verde, pasará a color azul y daremos 10 segundos para poder desactivar la alarma a través de nuestro teclado matricial, si la desactivamos, volverá de nuevo a escanear el campo, pero si no!! Reproducirá un sonido contundente y se dispondrá a mandarnos un sms a nuestro teléfono móvil y la fotografía a nuestro correo electrónico.

The famed @MBTweetFleet tweets using Arduino

Thursday, April 5th, 2012

In case you have been following MBTweetFleet and availing awesome parking spaces, you would be happy to know that the service was made using an Arduino and GPS/GPRS shield.

The cars automatically generated a tweet with GPS data out of every empty parking space they passed. Via Arduino the onboard electronics were connected to a GPS/GPRS-Shield. Tweets were generated with a PHP Relay which sent the GPS-Data. This is how people could find empty parking spaces near them on twitter and even be navigated there by a linked Google map

Retro Pinball Clock Hack

Wednesday, October 5th, 2011

[Alan Amon] posted a cool vintage hack on Instructables, adding GPS-based clock funcionalities to a Bally Wizard pinball.

Pinball machine will automatically power up at the preset time each day and then resets to display the current time, the year, the time the alarm is set for and the date month/day. Then as long as the GPS has a signal the time will update once a minute for the rest of the day.  At the time you would like to go to bed the Arduino will cut power to the game and it will remain off until the alarm time. Should you have a power failure in the night the machine will not lose it’s settings. If power is restored prior to the alarm time the machine will wake up as normal, otherwise the machine will wake up once power is restored.

If the game is powered on because it is not yet bed time and it is after the alarm time then at 12am, 1am or 1pm the game will do a full reset. This makes sure the clock hasn’t gotten off due to a stuck score reel, keeps the time in a 12 hour format and keeps the date display up to date.

Have a look at the “cool features” and “coolest features” in the instructables article

Listening To The Walls’ Whispers

Wednesday, September 7th, 2011

[Pierre] shares an interesting geo-localization project of sound, narration and  culture,  made in  ”plan d’Aou”, a district of Marseilles – France. The project dates back in September 2010, within the framework of the Smala project in order to trace a sound cartography of Islam in the city of Marseilles: the guys at [Echelle Inconnue] took their time to fully document the all project with schematics, codes, fritzing diagrams and so on.

Several mobile systems were distributed to the people to accompany their walk across the district with, by hand, a kind of speaker to be press on the walls which makes it possible to listen to the sound by vibrating the material of the wall.

The materials of urban furniture or buildings become the speakers required for sound diffusion. Each resonant body had its acoustic specificities, the words take shape in metal, wood or glass… Textures of the sound fluctuate from a surface to another and the listener must juggle with these characteristics to obtain a quality of optimal listening, between documentary in the walls and poetic sound creation.

Extreme Electric Racing With MIT eSuperbike, Arduino Controlled

Monday, June 13th, 2011

MIT PhD student Lennon Rodgers and his team of colleagues was among the 32 teams who entered this year’s all-electric race, bringing their custom-designed eSuperbike to the famous competition on the small island located between Ireland and Great Britain.

The brains of the bike are housed in an Arduino circuit board, which monitors data including the amount of energy used and the temperatures of each motor and battery. A screen on the dashboard continuously displays readings, allowing the rider to adjust the speed to conserve energy if needed. As a backup, the team made the system wireless, streaming data from the bike to their laptops — a modification the team’s rider, veteran Isle of Man racer and resident Allan Brew, appreciated.

Arduino balloon tracking

Wednesday, March 17th, 2010

Check out this GPS tracked baloon flying around Churchill College, Cambridge, on 07/03/10. No Code provided (yet) but still you can read a lot about the project on [Ferret] site and, offcourse, on [hackaday].
