UDOO as one of the most powerful embedded PC (SOM) of this date breaks borders in the price/ performance ratio.
There are several microcomputers on the market, which usually support OS Linux, Android or Windows. Their usage is so to say unlimited – from simpler devices, where we´ll use mainly a ready-made connectivity (USB, Ethernet, bluetooth, WiFi, …) to more sophisticated applications in combination with TFT LCD and a powerful graphics, video, etc. Each type has its advantages (Voipac, Embedded artists, Beagle board, Friendly ARM, Raspberry Pi, …) and one of the most surprising modules is surely the microcomputer UDOO. UDOO is a powerful single board embedded PC based on a powerful Freescale i.MX6 chip and it´s available in Dual or Quad core version.
In our offer can be found the more powerful Quad version (S975-G000-2100-C2, 1GHz), which is roughly 4x more powerful than for example Raspberry Pi. Power of this microcomputer is already really respectable and it manages various 3D visualizations, videos and (real time) communication through various interfaces. Interfaces – it´s the field where the UDOO excels, because it provides on one board interfaces like Gbit Ethernet, 4x USB, HDMI, WiFi, Touch, 76 GPIO, SATA, camera, microSD,… A big advantage is a full compatibility with an Arduino Mega 2560 platform (hardware and software)..
Functionality of the UDOO microcomputer is very wide and a detailed description can´t be summarized into a short article. The best overview of features and possibilities of this module will give you the attached video as well as basic UDOO user manual.

The Ciseco SRF shield instantly transforms any Arduino style board into a fully wireless device. There are no jumpers to worry about, no configuration to be done, simply plug in and begin coding. The shield utilises the world’s best value, secure wireless module, the SRF.
You can securely exchange data with all other Ciseco radio devices, including the ultra-long range ARF. Designed for ease of use, the shield uses normal ASCII when transferring data, requiring no library or complex software. This means all your memory space is for code, not to drive the radio. All settings can be accessed or changed via standard text based AT commands.
The shield has extra pads to allow for configurations such as; Over the Air Programming of your micro, low power sleep states and adding an external antenna to extend the range.
The SRF has flexible frequency and power settings, to cater for all global radio regulations; these are easily set in software.

Ultrasonic range finder using 8051 microcontroller has been already published by me in this website. This time it is an ultrasonic range finder using arduino. HC-SR04 ultrasonic range finder module is used as the sensor here. The display consists of a three digit multiplexed seven segment display. This range finder can measure up to 200 cm and has an accuracy of 1cm. There is an option for displaying the distance in inch also. Typical applications of this range finder are parking sensors, obstacle warning system, level controllers, terrain monitoring devices etc. Lets have a look at the HC-SR04 ultrasonic module first.

anool @ wyolum.com builds a pulse lamp controller for the parking light of his KTM bike. He writes:
My brother is a Mechanical Engineer who loves his KTM Duke 200 bike. He asked me to build this circuit : http://sunbizhosting.co.uk/~spiral/blog/?p=227 for a ‘heartbeat’ lamp controller for the parking light. A Neutral Detect (ND) signal controls the lamp pulsing. When ND is HIGH, the Lamp is fully lit. When ND goes LOW, the lamp starts pulsing.
I’m not familiar with PIC microcontrollers, and didn’t want to dabble in “C” code. I’d be comfortable with an Arduino, but even the smallest ATMega seemed too big (and overkill) for this simple requirement. How about an ATTiny ? A bit of Googling, and I found this excellent resource for running the Arduino environment on the ATTiny : http://hlt.media.mit.edu/?p=1695

By coupling a standard NMEA GPS receiver and an Arduino board we created a super simple and effective Arduino GPS logger. This device allows you to trace the route taken by a person or vehicle (or any other moving object) by simply doing a periodic caching of location points coming from the GPS unit. As the logger saves the list of records (containing data on recorded positions) on a microSD memory card, you can then move the data onto your computer and keep track of your trip. You can use tracked data to help project such as OpenStreetMap to grow and include new areas (www.openstreetmap.org).

This week FTDI Chip have announced a range of Arduino-compatible development platforms to support the company’s Embedded Video Engine (EVE) technology. The VM800P series provides engineers with everything necessary to implement Human Machine Interfaces (HMIs) featuring display, audio, touch elements and data processing aspects too.
The units can be programmed using the standard Arduino IDE (using a pre-programmed Arduino-compatible bootloader). In addition to support for various Arduino libraries, every VM800P incorporates an FTDI Chip FT800 EVE graphic controller IC and its FT232R USB interface IC as well as an ATMega328P 8-bit microcontroller running at 16 MHz. Also featured are a touch-enabled display LCD panel, a backlight LED driver, an audio power amplifier and a micro speaker. A choice of 3.5, 4.3 and 5.0-inch display formats is available which have precision fitted bezels to enable operation in industrial environments. The VM800P units also have a USB serial port for firmware upload and application communication, a battery-backed real time clock (RTC) for carrying out system timing and a micro SD socket loaded with a 4GByte SD card containing sample applications.

WatchDuino is an open hardware project that combines inexpensive electronic components and a complex Arduino (C++) code to build a useful and reprogrammable smart watch.
The code and the components have been optimized after a lot of prototypes to provide a rich set of features with a small and cheap battery that can last more than a week without recharging. A lot of electronic and software engineering was required to make this project possible.

Possibly the smallestest ATtiny85 based ‘duino derivative.
Recently, Olimex anncounced the Olimexino 85s, claimed to be the “World’s smallest Arduino ever“. Now, that looks like a challenge. I guess it is about time to show off what has been on my desk since some time last year: The Nanite, pictured below.
I designed this board for fun after the Digispark and, subsequentally, the Adafruit Trinket were announced. The motivation was to have my own ATtiny85 based development board based on a USB bootloader and optimized for the ubiquitous 170 point mini-breadboards. In contrast to the Digispark it even sports a reset button. However, it lacks an integrated voltage converter as it is supposed to be powered by USB.
