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…
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.
“Quick question? How are you amplifying the EEG signals before feeding them into the arduino? I ask because all of the neuroscience researchers I’ve talked to say you need an amplifier roughly the size of a VCR to bring the signals up to levels at which they can be analyzed. If you’ve found a way to just plug wires from the electrode pads into the analog inputs on an arduino that would be quite the breakthrough. Also is there any chance you’d be willing to demo your code for separating the brain activity on the EEG from noise created by environmental effects and muscle movements since I’m sure you know that something as small as an eye blink creates an electrical impulse at the scalp which dwarfs the majority of the brain’s electrical signals when measured through the skull. “
Unlike the other post that we made about brain-controlled devices using an Emotiv headset, this one claims to recognize different words.
They outfitted volunteers with caps with EEG sensors, and asked them to steer a helicopter on a computer screen through a series of randomly generated rings that appeared on the screen ahead of it. There were no hand controls, no joysticks. They could only try to will the helicopter forward with their minds.
[Robotgrrl] shared a super-userful way to import Arduino Data to Mac applications, with tutorials and examples.
We created Matatino, a framework that lets you communicate between your Mac applications and your Arduino, You can follow our tutorials to get started with adding Matatino to your project. To see Matatino in action, check out Meters for Arduino. We will be adding more examples, libraries and tutorials for the Android ADK, iOS Redpark Serial Cable, Processing and OpenFrameworks in the future! You can stay informed about updates through RobotGrrl’s blog Apps4Arduino category feed.
There isn’t actually much new about this awesome DIY project, but it’s the way it brings the various parts together that has us impressed. Designed by Instructables user XenonJohn, with help from software developer David Findlay, the Magic Music Table RFID was designed to let a disable child (or other such handicapped user) select albums to play back from an iPod touch playlist. The iPod is connected to anArduino, which tells the device to start playing a particular track based on a selection made with RFIDcards. The whole setup is built into a coffee table and the RFID tags are sandwiched inside clear plastic blocks with the album art. You can see it in action in the video after the break and, if you’ve got the patience and skill, you can build your own using the directions at the source link.
Interesting Workshop at ISEA 2011 in Istanbul led by Anna Dumitriu and Tom Keene with Alex May. The aim of the workshop is building and calibrating iPhone compatible/connectable Galvanic Skin Response Sensors (GSR) to record subtle changes in emotion.
This very personal sensor data will then be shared online. Participants will also collaborate to develop a networked performance intervention to take place at ISEA 2011 that engages with the social benefits and ethical implications of disclosing such personal information as arousal levels within the public realm.
Participants will learn to solder and connect their own GSR sensors, connect them to their iPhones and share their sensor data online. There will be a discussion of the implications of this technology and the increasing issues of privacy as pervasive computing technology is increasingly able to record and reveal personal details. Finally participants will work with the workshop leaders to improvise, plan and rehearse an intervention performance work that will be performed at the end of the second day. This performance may be very subtle and not immediately obvious to any audience members that may be around, again playing with ideas of what we do and do not reveal to those around us.
Here is how it works. I have an Arduino Duemilanove with ATMega328 which has two photo-resistors connected (with a 10k pull down resistor). I set up two laser pointers to shine a laser directly onto the photo-resistor (which is enclosed within a dark box). The Arduino monitors the values returned from the light sensor, and watches for any changes that indicate that the laser bean has been broken. When both laser beams are broken, the Arduino calculates the amount of time between when each sensor was tripped. It then sends that value to the Adobe AIR based client, which is connected to the Arduino via USB / Serial port and a serial port proxy (in the case, TinkerProxy).
You can get the schematics and the codes from this project on Mike’s github.
Here is a compilation video I threw together showing my LED suit in action this past weekend at Dragon*Con 2010 in Atlanta. More build reports, photos, and video to come soon.
Some time ago I posted previous experiment in wearable leds cloth. In this case is more of a structure underneath a peculiar cloth. It’s controlled by iPhone with an app wrote from [uiproductions]. In this video everything is explained in a detailed way.
Yelp – which not long ago organized its first hackathon – replicated the event after six months. These are the winners:
Useful: Adam D., Evrhet M., Mark A., and Minh T. created a Q&A service that would let users ask and answer questions about a particular business.
Funny: Need to know when we’re launching our next product or how many users have signed up today? Then look no further than the Yelp Jumbo-Tron-O-Matic courtesy of Ben B., Jon M., Eskil O., Evan K., Daniel C., and James B.
Cool: At Yelp, we don’t mess around with our beer. To make sure we never run dry or get a bad pint, the geniuses on this team — John B., Gabe H., Alex D., Julien R., and Jeff M. — built the Kegbot. Controlled by an iPad app, you can tell how much beer is being emptied (and at what rate: cough, John), as well as leave a 5 star review for your brew.
The iPad-monitored brewing machine maybe not the cheapiest solution for your bar, but it’s definetly Cool. I wonder wether there are videos from the other two winners.
Many ipad sproofs in these days. This one Arduino based. The interesting thing is the merchandising of old typewriters. Vintage revenge.
The Typewriter Dock, seen in the video above, is an even better version. It holds an iPad in its carriage whilst simultaneously inputting typed letters. All it needs is a Bluetooth component to replace the cable, and a writing app that can use the accelerometer to detect a carriage return and move you to a new line. Ding!
Inside there is a sensor strip under the keyboard which detects the key-presses that hit it, and this pulse of electricity is then passed on to an Arduino circuit-board whereupon it is translated into a standard USB key-down event. All you need to do is plug it in and type.
