smARtDUINO Open System Provides a Low Cost Modular Arduino Platform

smARtDUINO is a new platform design by the former ARDUINO’s manufacturer (Update: This claim appears to be incorrect and a lie) composed of several compact modules and is a fully funded project on Kickstarter (Less than 3 days remain to become a sponsor). The platform is not based on a single processor, architecture or language but, makes use of an universal platform that can be used to connect components originally developed from different companies, technologies and form factors. For example, it is possible to integrate modules, accessories or shields from Arduino, Netduino, ChipKit and even interact with smartphone using an ADK module, without having to use a breadboard and/or soldering. Interoperability is made possible thanks to what they call “smARtBUS Open I/O“, which is a standard for connectors designed after looking at existing (Arduino) platforms on the market. The company opted for 2 solutions composed of 2 connectors: smARtBUS BASIC […]

Arduino Due Cortex M3 Board is now Available

Announced a little over a year ago, the Arduino (over) Due based on Atmel SAM3U Cortex M3 MCU is finally available for purchase. The specifications of the new boards are as follows: Microcontroller – Atmel AT91SAM3X8E @ 84 Mhz Flash Memory – 512 KB SRAM – 96 KB (64 + 32 KB) Operating Voltage – 3.3V Input Voltage (recommended) – 7-12V Input Voltage (min/max) – 6-20V Digital I/O Pins – 54 including 6 supporting PWM Analog Input Pins – 12 Analog Output Pins – 2 (DAC) Total DC Output Current on all I/O lines – 130 mA DC Current for 3.3V Pin – 800 mA DC Current for 5V Pin – Theoretical 1A, recommended 800 mA Debug ports – JTAG/SWD connector The new board is mostly compatible with the AVR (8-bit) boards, but since the board runs at 3.3V some shields may not be compatible (Arduino Wi-Fi and Ethernet shields do […]

$25 Outbreak Galago – Cortex M3 Open Hardware Development Kit

Outbreak Galago is a tiny development kit based on a Cortex M3 processor that fits a debugger, and is destined for rapid electronics prototyping. The company promotes it as some sort of Arduino board on steroid (MCU wise) and sells for $25 on kickstarter, and less than $10 in 10k quantities. Here are the board specifications: 72 MHz 32-bit ARM CPU with 32KB of flash ROM and 8KB of RAM (NXP LPC1313 TBC) Integrated hardware debugger One high-speed SPI port, up to 36 Mbps One high-speed I2C port, up to 1.5 Mbps One UART/USART with hardware flow-control capability, up to 256 kbps 10 high-speed PWM pins, 6 driven by 32-bit (high-resolution) timers 6 ADC (analog) input pins with 10-bit resolution at over 400 KSa/sec 25 GPIO (digital) input/output pins The form factor and built-in debugger (via USB) are not really new, as those are already featured in devkit such as TI Piccolo controlSTICK, […]

How to Get Free Hotel Rooms with An Arduino Board and a Resistor

Earlier this week, Cody Brocious (Daeken) gave a presentation at the Black Hat conference in Las Vegas showing how it was possible to hack and open hotel door locks (Onity HT lock systems), using an Arduino Mega 128 board, a 5.6 kOhm resistor and a DC barrel plug to physically mate with the lock (Total price: around $20). He explains that 4 million hotel rooms are fitted with this type of lock, which means you could potentially stay for free anywhere in the world. Obviously, you could also end-up in another type of room (including free food) for a longer period of time. That looks like a win-win situation to me 🙂 Each locks contain a 32-bit unique value (sitecode) that identifies a property, and is used for encryption. Cody’s Arduino’s based solution can communicate with the lock over a 1-wire communication protocol read memory to get the sitecode (no […]

16 Euros Arduino Leonardo Board is Now Available

Arduino Leonardo is a new Arduino board with a 16 MHz Atmega32U4, 2.5KB RAM, 32 KB of Flash memory, 20 digital I/O, 12 analog inputs and 7 PWM outputs. In this version the MCU takes care of USB communication with the host, whereas for Arduino Uno, a separate chip is required to take care of this, which makes Arduino Leonardo cheaper than Uno. Here’s a summary of Arduino Leonardo specifications: Microcontroller – Atmel ATmega32u4 @ 16 MHz SRAM – 2.5 KB onchip (ATmega32u4) Flash Memory – 32 KB onchip (ATmega32u4) of which 4 KB used by bootloader EEPROM – 1 KB onchip (ATmega32u4) Operating Voltage – 5V Input Voltage – (recommended) 7-12V | (limits) 6-20V Digital I/O – 20 pins PWM – 7 channels Analog Input – 12 channels DC Current per I/O Pin – 40 mA DC Current for 3.3V Pin – 50 mA Watch the video to get […]

AnDevCon IV Classes and Workshops Schedule

AnDevCon is a technical conference for software developers building Android apps, and the fourth Android developer conference will take place in San Francisco on December 4-7, 2012. The organizers have already listed the schedule, including details about the workshops and classes which will take place at the conference. The 4th of December is reserved for workshops, and the other 3 days can be spent on shorter classes. All workshops will provide sample code, as well as most classes, excluding the overview session and business related sessions. There will be three full day Android workshops: Android Development Boot Camp – Hands-on introduction to Android application development and the tools essential to the process. Beyond an introduction to the basics, this workshop also covers some of the common hurdles met with development, and how to overcome them. You will also have the opportunity to build an Android app of your own where […]

WiFi Tank Based on EEE PC, Arduino, Ubuntu and Node.js

Eight computer and electrical engineers built a WiFi Tank (Node.js robot) as part of a senior design project at Northeastern University, in Boston, Massachusetts. The robot brain is an EEE PC running Ubuntu, together with an Arduino board and is programmed using node.js. Each tank is equipped with a camera and 2 customized Wi-Fi repeaters (which it can drop it extend range), and it’s targeted at military operations or disaster-affected areas where network infrastructure is not available. Here are the key characteristics of this robot Robot controlled over WiFi 102 cm long, 71 cm wide, 41 cm tall, about 68 kg. Custom-built (except for treads) out of aluminum Range: 1 km with one on-board router and two droppable long-range repeater modules Running time: ~12 hours On-board webcam with microphone, night vision, pan and tilt On-board GPS for location tracking Custom-made remote user interface, works on any device with a web […]
