Don’t want dogs pooping on the front lawn? You could put up a sign, your could chase them away like a crotchety old miser, or you could build a motion detecting sprinkler system. It’s pretty hard to line up for a doody when you’re getting sprayed in the face (or worse) with cold water.

The setup is pretty simple. The bump-in image above shows the view from a webcam. The server monitoring the video is running software that detects motion between one frame and the next. When it sees something in the right position it signals an Arduino to trigger the solenoid which has been holding back the water. Check out the movie after the break which shows [Phil Tucker] tramping across the grass to trigger the  trap.

Sprinkler hacks are always a lot of fun. This variable-range sprinkler is still one of our favorites.

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…

Not using an Arduino, yet a very useful must-have on every maker’s table. Of course not as awesome as a real safety glass, but then, it is a nice start.

Materials required: An empty, washed 2 liter soda bottle, an elastic band, a pair of scissors, a permanent marker.

All you have to do is cut off the top and bottom of the soda bottle, then cut through the remaining plastic to turn it into a single plastic sheet. Then hold the plastic sheet around your face and draw the goggles with a plastic marker. Cut them out, attach the elastic band to both sides, and you’re done!

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.

Ella Smith, age 10, is an interesting young lady. At an age when most girls are fussing over the new dresses for the dolls, Ella actually started tinkering. She made Zeverino – a timely cat feeding device alongwith her father. With a passion for animals and an ambition to become a veterinarian, this young techie is a combination to watch out for.

An interesting interview with her had her naming soldering iron as her favorite tool to work with.

Kudos to the young lady and her father!
