Embedded Lab’s new development board for PIC12F series microcontrollers:
The 12F series of PIC microcontrollers are handy little 8-pin devices designed for small embedded applications that do not require too many I/O resources, and where small size is advantageous. These applications include a wide range of everyday products such as hair dryers, electric toothbrushes, rice cookers, vacuum cleaners, coffee makers, and blenders. Despite their small size, the PIC12F series microcontrollers offer many advanced features including wide operating voltage, internal programmable oscillator, 4 channels of 10-bit ADC, on-board EEPROM memory, on-chip voltage reference, multiple communication peripherals (UART, SPI, and I2C), PWM, and more. Today we are introducing a new development board (rapidPIC-08 V1.0) for easy and rapid prototyping of standalone applications using PIC12F microcontrollers.

Jie Qi from the MIT Media Lab and Bunnie from Studio Kosagi are hoping to crowdfund their idea for a new method of circuit building called Circuit Stickers.
A crossover between high tech and arts and craft, Circuit Stickers are not a serious prototyping tool but aim to find new uses for easily configurable electronics circuits so that they can be incorporated into other media such as books (basic science or fiction) or even wearable electronics.
Interconnect and power tracks made from sticky copper tape (or other conducting material) are laid out on any non conducting surface such as paper, material or flexible fabric. The individual components come ready-mounted and connect to the copper tracks via pads with sticky anisotropic (Z) tape. These can be peeled off later for reuse. There are two kits available containing a sketchbook to take you through the basics, colored LEDs, sound, light and trigger sensors and a tiny microcontroller with an ISP programming connector. That old Tee shirt looking a bit tired? Spruce it up with a running light display. [via]

By Jim Harrison:
The human-machine interface, once simply known as an “operator panel” or “terminal”, is changing rapidly, due to the graphical, visual way operators now interact with an industrial machine or process. At one time, designers of these systems could get by with a three-line segmented LCD display. Today, LCD interfaces are quickly replacing traditional LED and segment LCD displays as designers take advantage of the aesthetic, flexibility, and cost benefits they provide.

This project is an Automatic School bell system. Such a system triggers a bell (or operates any other load) at predifined time. In this version some advanced features are introduced. I used PIC18f4520 microcontroller as the brain of the system. RTC1307 IC is used to maintain the clock,date and day with a 3V backup voltage battery. Bell timings are stored in the internal EEPROM of mcu.

We all might have fond (or maybe not so fond) memories of the first MCU we used, but where does that device and the many others that you may have also used and read about. So we asked MCU manufacturers to tell us which of their MCU lines has been the most popular ever and list their selections in this slideshow.
But are these the MCUs you’d choose as the most popular? Take a look at each participating MCU manufacturer’s top MCU – and then tell us which you’d call the most-popular. Or if another MCU not listed here deserves to be called the most popular, tell us!

Sleep modes and idle modes in general-purpose microcontrollers have allowed embedded processors to reduce real-time energy consumption and tackle many battery- and low-powered designs. However, as embedded systems become increasingly complex, it takes additional logic to implement a denser, more sophisticated micro core as well as the higher-end peripherals we expect to see today. As a result, even in standby modes, static power draw can be an issue when trying to reduce energy, especially if long sleep times are required.

IR Communications for Atmel Mega644/1284 microcontrollers.
Infrared (IR) can be used for line-of-sight communications over low to moderate range. IR is nice because of the lack of interference (except for sun and compact fluroscent lights) and freedom from FCC regulation. The web site http://tthheessiiss.wordpress.com/2009/08/05/dirt-cheap-wireless/ (Jacob Sikker Remin, 2009) shows how to use a IR remote control receiver and IR LED to send ASCII serial data in a simple, but unreliable, fashion with no error control, packetizing, or other overhead. The transmitter drive uses a clever method to modulate and invert the serial output from the USART transmitter. The circuit is shown below.

10 Tiny Development Boards That Are Up to the Task @ EE Times.
Not so long ago, the typical development board was big, bulky, and often handmade. Recently a flood of Lilliputian-size development boards has been released — one for just about any need.We’ve assembled a collection of 10 boards so small you might lose them in the cushions of your couch.

Programming microcontrollers isn’t hard. Building a programmer makes a great first electronics project. The goal of this instructable is to explain the simple ‘in circuit serial programming’ method used with Microchip PICs.
