Here is a very nice build of a LED heart that creates incredible animations. Check it out.
Today we present the perfect Valentine gadget: just shake it and it will turn on and crate incredible light animations. That will be cool for sure!
We know that, as it’s Valentine’s Day, looking at the device described in this post you’ll be inclined to think that this is the usual heart-shaped Valentine gadget: in reality this is something much cooler as it’s capable to create beautiful and complex light games. Is based on the smallest microcontroller manufactured by Atmel: the ATtiny85.

It consists of a power supply, the basic components for running the microcontroller (i.e. crystal, reset pin, …) and ICSP connector for In-Circuit programming. All pins are available on a header strip, so it is ideal for rapid prototyping.

DigiPot is a digital potentiometer using a rotary encoder as input along with a 7 segment display that show the current pot value.
The “potentiometer” is actually a rotary encoder (TW-700198) connected to a microcontroller that reads the signal from it and convert it to a value that is displayed on 7-segment displays. The value also is sent via i2c/spi/serial/usb to the host. Also 3 LED and included for status indication.

The solution is an embedded module. Swedish company Embedded Artists will help you in tit by their top-class modules with NXP processors.
Embedded modules are still more used in many products, where so far a classic microcontroller was sufficient. As requirements for functionality of devices are increasing, including audio/video output, network- and USB connectivity, as well as a possibility to be programmed by a user, to change firmware, etc, the development is more and more demanding. For small and middle-sized companies it can easily happen, that in respect to a supposed sale, the expenses will never return. In the most cases, it´s better and at the end of the day even cheaper to rely on some of so called embedded modules. An embedded module (depending on a type) usually provides all necessary for controlling of our device and it is usually easily programmable thanks to a standard OS implemented (Linux, Android, Windows,…).
Embedded Artists products are based on top-class NXP processors LPC with Cortex M0, Cortex M3 and Cortex M4 cores, but also on older ARM7. As Embedded Artists have a closed cooperation with NXP (they are an NXP certified partner), they have an excellent knowledge of these perspective chips. Among
Embedded Artists can be found:
- development kits
- OEM boards suitable for direct usage in products
- “quick-start” boards
- education boards
- display boards
- various accessories for development support
From a final product and production point of view, the most interesting are the OEM modules. Embedded Artists provides a wide support to their products and for example notes for usage of OEM modules in praxis can be found in the OEM Integration guide. An example of a price calculation – decision “own development or an embedded module” is illustrated in the attached picture. Many Embedded Artists products are in our stock ready for immediate shipment. We´re able to deliver you any other Embedded Artists product with a short leadtime.

Raj @ embedded-lab.com build a mini LED Christmas tree for his son. He writes:
My two and a half year old son loves toys with flashing lights. For this Christmas I thought of making a mini LED Christmas tree for him. This project uses 22 multi-color LEDs which are driven by a PIC12F683 microcontroller using the Charlieplexing technique. The details of the build procedure is described in the following sections.

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.

Brian posted an article describing how he designed and built his business card:
A business card should represent a person’s expertise. My expertise is in creating unique circuit boards, so to celebrate this I wanted to create a USB thumb drive circuit that contains my resume and contact information. This was also a great way to experience coding for USB applications using the Cortex M series of microcontrollers. As a side note, I have done other projects with Cortex M including a simple serial relay and a USB keyboard emulator, but this is the first one that is exciting enough to write about.

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]

Intel® Galileo – Intel® Galileo is the first in a line of Arduino-compatible development boards based on Intel architecture.
Galileo is a microcontroller board based on the Intel® Quark SoC X1000 Application Processor, a 32-bit Intel Pentium-class system on a chip. It is the first board based on Intel® architecture designed to behardware and software pin-compatible with Arduino shields designed for the Uno R3. Digital pins 0 to 13 (and the adjacent AREF and GND pins), Analog inputs 0 to 5, the power header, ICSP header, and the UART port pins (0 and 1), are all in the same locations as on the Arduino Uno R3.
Now there is an Intel based Arduino – Intel Galileo - [Link]
