Punch Through’s new Arduino board can stay wireless forever

lightblue-cortadoYou’ll have to plug in a typical Arduino-compatible board at some point in its life, whether it’s to add code or just to supply power. Not Punch Through Design’s upcoming Cortado, however. The tiny device centers on a custom Bluetooth 4.0 LE module that both enables wireless programming (including through mobile apps) and helps the board last for more than a year on a replaceable watch battery.

In fact, the Cortado will already be powered up when you get it — you can start coding before you’ve opened the shipping box. It should also be relatively flexible for its size with a built-in accelerometer and the ability to serve as an Apple iBeacon transmitter. Punch Through is crowdfunding the board with hopes of shipping its first units in May. If you’re interested, you can pledge $18 to pre-order a Cortado.

Flutter: A $20 wireless Arduino with a long reach

flutterwirelessarduinojtFrom Postscapes:

Flutter is a new long range development platform based on Arduino that is looking to provide Makers with an inexpensive and reliable wireless technology to get their projects going just a little bit further than they have been with typical Bluetooth, Zigbee and WiFi solutions.

Developers Taylor Alexander and Katelynn Cusanelli created Flutter to be used without a router and achieve a range of up to 1000 meters (transmitted in the 915 Mhz range) for use in projects as diverse as monitoring remote temperature sensors, to controlling quadcopters and RC cars.

Do you need to receive data from even longer distances? Using mesh networking the platform can be scaled to use thousands of Flutter devices to extend the operating range and open up new types of project options. Getting connected to each board is as simple as configuring the device using a USB from your computer or by using the projects add-on shields (Wifi & Ethernet or Bluetooth) and a mobile app for authentication using your phone.

Security is also a focal point for Flutter’s creators. Every Flutter device will have a unique 72-bit serial number and has Atmel’s ATSHA204 cryptographic chip on-board to hold up to sixteen 256-bit encryption keys while adding an additional layer of data and device protection.

Welcome Arduino Yún

Arduino_Y_n_isoMassimo Banzi announced it some minutes ago during his annual “The state of Arduino” presentation at Maker Faire Bay Area:  Arduino Yún  is the first of a revolutionary family of wifi products combining Arduino with Linux.

Yún means “cloud” in chinese language,  as the purpose of this board to make it simple to connect to complex web services directly from Arduino.

Designed in collaboration with Dog Hunter, a company with extensive experience with Linux, the board adopts the Linino distribution which provides signed packages to ensure the authenticity of the software installed on the device.

Historically, interfacing Arduino with complex web services has been quite a challenge due to the limited memory available and they tend to use verbose text based formats like XML that require quite a lot or ram to parse. On the Arduino Yún we have created the Bridge library which delegates all network connections and processing of HTTP transactions to the Linux machine.

Arduino Yún is the combination of a classic Arduino Leonardo (based on the Atmega32U4 processor) with a Wifi system-on-a-chip running Linino (a MIPS GNU/Linux based on OpenWRT). It’s based on the ATMega32u4 microcontroller and on the Atheros AR9331, a system on a chip running Linino, a customized version of OpenWRT, the most used Linux distribution for embedded devices.

Like a Leonardo, it has 14 digital input/output pins (of which 7 can be used as PWM outputs and 12 as analog inputs), a 16 MHz crystal oscillator and a micro USB connector.

tonguesensorplacementWe know the human tongue is extremely sensitive. Go ahead: touch something with your tongue. There isn’t a naked surface on your body that’s better equipped for sheer sensation. There’s nothing more plastic, built to adapt and optimize itself for new experiences. Not only is your tongue fully equipped with a sense-optimized surface, but anything you experience on your tongue gets mainlined directly into your brain. So if we’re serious about hacking the body to provide new kinds of sense experiences, forget about the fingertips. Forget anything on the outside of the skull. The answer is obvious: trick out your tongue.

The Tongueduino is the brainchild of MIT Media Lab’s Gershon Dublon. It’s a three by three electrode pad that rests on your tongue, runs through an Arduino controller, and connects to one of several environmental sensors. Each sensor might register electromagnetic fields, visual data, sound, ambient movement — anything that can be converted into an electronic signal. In principle, this could allow blind or deaf users to “see” or “hear” with their tongues, or augment the body with extrahuman senses.

Dublon, an electric engineer by training, studies how “sensor networks might become extensions of our nervous systems — networks of remote, distributed sensing prosthetics.” He has been experimenting with his Tongueduino himself for the past year and is now beginning training with a group of twelve volunteers. “Through Tongueduino, we hope to bring electro-tactile sensory substitution beyond the discourse of vision replacement, towards open-ended sensory augmentation that anyone can access,” he writes.

Raspberry Pi to Arduino shields connection bridge

The idea behind the Raspberry Pi to Arduino shields connection bridge is to allow to use any of the shields, boards and modules designed for Arduino in Raspberry Pi. It includes also the possibility of connecting digital and analog sensors, using the same pinout of Arduino but with the power and capabilities of Raspberry.

In order to make complete the compatibility we have created the arduPi library which allows to use Raspberry with the same code used in Arduino. To do so, we have implemented conversion functions so that you can control in the same way as in Arduino all the I/O interfaces: i2C, SPI, UART, analog, digital, in Raspberry Pi.

Let’s summarize what we can do using this shield along with the arduPi library:

  • Connect any Arduino Wireless module in Raspberry. Some examples: XBee 802.15.4/XBee ZigBee, RFID, NFC, Bluetooth, Bluetooth Pro, Wifi, GPRS, 3G
  • Connect any sensor (analog 0-5V, digital) to Raspberry Pi with a precession of 16b using the ADC integrated. Connect also complex sensors through i2C and UART buses
  • Connect any Arduino specific shield such as: Radiation sensor shield, CanBus, Relay shield,…
  • Connect any electronic module or actuator which works over i2C, SPI, UART

TinyDuino Microcontroller Is Smaller Than a Quarter

Arduino is probably the world’s most popular open source physical computing platform. The little microcontrollers show up in everything from wild art projects to serious home automation efforts. It’s great and all, but couldn’t it be … smaller? Electrical engineer Ken Burns thought so, and got to work on the TinyDuino.

TinyDuino is a fully Arduino-compatible hardware platform, complete with expansion shields (add-on boards that have specific sensors or lights, for you non-robot designers). But where an Arduino Uno is around the size of a credit card, the TinyDuino is smaller than a quarter, and its sibling the TinyLily is the size of a dime. The TinyDuino line is designed around three core elements: size, affordability, and expandability. The idea, says Burns, is to open up Arduino to a whole host of applications that simply aren’t possible with the larger board.

The seeds of TinyDuino were planted when Burns was working on creating smart sensors. The goal was sensors that would be plug and play, with on-board intelligence that allowed them to handle all the hard stuff, like reading data, calibration, and formatting the output. “For a typical hobbyist, this would mean you could just plug in any sensor, whether it’s temperature, pressure, light–whatever, and your system would read it out and know what it was and the units it was in.”

Burns says that Arduino was a natural fit as a basis for the work. When he shared his progress with friends and members of the SYN/HAK hackerspace, “it became pretty apparent that there were others that were very interested in having very tiny Arduino compatible processor modules,” Burns says. Focus switched over to designing a family around this core concept.

The TinyDuino is an exercise in design extremes. When you start cutting a hardware board down to the size of pocket change, it forces you to make a lot of serious decisions about what features are needed. In order to cut the TinyDuino down to size, Burns says, they moved a lot of the default affordances of the Arduino hardware, like the USB connector, on to TinyShields. (A similarly-shrunken Arduino project, the Digispark, has the USB plug built in, similar to a small thumbdrive ). TinyShields are an intensification of the shield paradigm that is already an important part of Arduino hardware.

“If you look at the board itself,” says Burns, “it’s really just a core processor that brings out signals to pins.” Ordinarily, those pins need to be attached (often through soldering) to electronics that can process the signals and turn them into motion, light, sound, WiFi, etc.
