If you have problems with waking up in the morning- this alarm should help. This alarm clock isn’t so easy to turn off as it requires some brain action. Alarm clock is equipped with LCD screen where a math problem is displayed when alarm is triggered. So you have to solve a problem like 23×17+6 in order to turn off and alarm.

Project is based on PIC16 microcontroller. Project is presented as open source. Download source code and project files including schematic and PCB, if you want to build one for yourself. Author also provides suggestions for improvements like adding backup battery, or single chip radio. Really cool project that can be made from parts available around.

This is small blinking LED demo application for LPC2103 Olimex board. Project compilation was made under Linux by using GCC tools and debugged openOCD debugging software.

Benedikt Sauter describes the process of building project with arm-elf-gcc and debugging with openOCD via JTAG interface. Follow these steps and you will make your first ARM7 project under Linux. Necessary project files can be downloaded here.

Sensor Hub board so called SAK2 (Swiss-Army-Knife 2) board was developed to be flexible data acquisition board which may serve as single dev board or as part of distributed system like wearable platforms. Board can be interfaced with various sensors, serve as chain for data stream applications. It can work as stand alone board if needed.

The board is equipped with 16 bit with 32kB Flash program memory PIC18F452 microcontroller clocked at 40MHz (10MIPS). Other parts on board include: 2.4GHz wireless RF transceiver with 125 channels, Compact Flash card connector, DS1302Z real-time clock with battery backup, a bunch of connectors for I2C, RS232, board to board, programming. All project files including, schematics, firmware, and layout are available for download.

This is cool project to pay attention to. It can be used for PC modding or elsewhere where scrolling text effects are needed. Display is built of 50×7 LEDs that is controlled by AVR AT90S2313 microcontroller (may be substituted by ATtiny2313).

Text can be sent from computer via RS232 port or displayed from external EEPROM 2k memory where 768 characters can be stored. Fonts set of 256 different characters can also be programmed and mast be written to EEPROM before sending text to display. Hardware project with 3mm LEDs can be downloaded here. And latest firmware here. There might be minor changes are needed to adapt to newer WinAVR and ATtiny2313 microcontroller.
