I’m continuing working with Juan Brito and Danny Macancela from the blog Desafio Ecuador, developing new boards to bring near the technology and programming languages. Our last work is a board to use with the Raspberry Pi and focused to learn Python. The board has the basic elements to start with this language. Also, with the develop of the PCB we remove the wiring, avoiding troubles with connections, inversion polarity…So with this board you only focused in the software develop, because the hardware side will work!
Baoshi of DigitalMe wrote an article detailing his minimalism ATTiny2313 development board build:
The AVR chip I’m talking about is Atmel ATTiny2313, in SOIC-20 package. To make the development board, I bought some 28 pin SOIC/SSOP to DIP adapters. These adaptors usually come in double sided design. Corresponding pins on both sides are connected via the plated through holes at edges.
I made a 2×3 AVR programming header by pulling off pins (longer ones) from a double-row right angle pin header and reinsert them into the plastic base. A needle nose pliers is very handy for this purpose.

MCUs offer a very wide range of Ethernet connectivity choices. With most applications demanding Internet connectivity, it’s more likely than not that your next MCU-based design will need some type of network connection. Whether your next design is a sensor that needs to consolidate and communicate data over an Ethernet link, a network-connected security camera that needs to have periodic code updates sent via the network connection, or an industrial controller that needs to use a robust industrial Ethernet connection, your choice of Ethernet-enabled MCU will be critical in delivering the capabilities required for a successful design.

TI’s MSP430 family of MCUs are low-power and RISC-based powerful mixed-signal processors that require a Flash Emulator Tool (FET) for in-system programming. The official MSP430 FET from TI costs about $100. Vincete describes a way to construct a MSP430 FET using TI’s popular and in-expensive Launchpad board.

Atmel have announced the introduction of the SAMA5D4 to their SAMA5 family of microcontrollers. These use an ARM Cortex A5 core and the new D4 adds H264, VP8 and MPEG4 720p video playback capability at 30fps.
According to Jacko Wilbrink, sr. director of MPUs at Atmel “With the large market acceptance of the Atmel SAMA5D3 Cortex®-A5-based MPUs, we are continuing to shape experiences surrounding the user interface for industrial and consumer applications. The SAMA5D4 enables the addition of video playback to control panels and displays at an unrivalled cost point, security and counterfeiting are becoming growing concerns within the rapidly growing IoT market. These applications require MPUs with advanced encryption while maintaining the same level of high performance. Atmel® | SMART™ SAMA5D4 is positioned to deliver the security and performance many Internet-connected systems require.”

An inexpensive single board computer which connects to a composite video monitor, keyboard, and SD card by Jack Eisenmann:
I created the DUO Light as a low cost platform for hobbyists to create fun and useful software. The DUO Light is ideal for anyone who wants a low power computer with video output and keyboard input.
The DUO Light is a hybrid of the Arduino UNO and the Raspberry Pi, but costs less than each. At the heart of the DUO Light is the ATMega328, the same microcontroller as in the Arduino UNO. This chip connects to a variety of peripheral devices, including a composite video monitor and SD card (in a similar fashion to the Raspberry Pi), PS/2 keyboard, and general purpose I/O ports. The second chip onboard is a 64 KB serial SRAM, which also connects to the ATMega328.

DS18B20 is a programmable resolution 1-wire digital thermometer.
It has an operating temperature range of -55°C to +125°C and is accurate to ±0.5°C over the range of -10°C to +85°C.
This library is an AVR implementation to retrive temperature from DS18B20.

At the Intel Developer Forum held in San Francisco Intel’s Corporation CEO Brian Krzanich announced how a broad set of computing initiatives and projects would allow the company to move quickly into new market segments where everything is smart and connected. He showcased the Edison development board which the company first announced back in January. It was planned to be the size of a full size SD card but the finished article is slightly bigger. The board measures 25 x 35.5 mm, about half the size of an Arduino UNO

Back when I was only starting to dabble in electronics, I needed a project that would meet the following requirements:
simple to make;
original (i.e. done entirely by myself from scratch);
containing a microcontroller;
and maybe the most important of all, useful. I’ve had enough devices I assembled just to dismantle the whole thing a month later.
The thing I came up with at the time was a light swich for my room controlled over an IR remote from TV. Remote that I had used RC-5 protocol, hence the firmware is suited for any RC-5 compatible remote.
Everyone is familiar to the everliving problem with switching the lights off in your room before going to bed and stumbling back across the room. The IR switch I describe here solves that problem, and I can definitely tell that this project was a success – I am still using it with no regret.
