The Network Time Protocol (NTP) has revolutionized the world. Suddenly one could have anywhere in the world accurate time and date. NTP is a simple UDP based protocol and can be implemented in a Microcontroller. Using the tuxgraphics ethernet board and a LCD display we can build a nice clock which gets time and date via NTP. Just attach it to you DSL router.[more]

A touch sensor developed for use in a range of projects for fabrica interactive. The sensor is designed to take a reading and then communicate that reading digitally so that the sensor can be placed at a distance away from whatever is reading it (A microcontroller / other physical computing interface) [more]

An Atmel AT89C51AC2 microcontroller development board with Optrex DMC 16207 16×2 LCD display, 4×4 keyboard, speaker and 64MB Compact Flash storage. Low level C hardware interface functions are implemented so the keyboard, beeper and display are accessed with high level printf() and scanf() routines. Short filename DOS files may be read from, and written to the root of the FAT16 formatted Compact Flash media.[more]

The clock is synchronised via the German time signal DCF77. It has a display with automatic brightness control and a RS232 computer interface.
Arvin writes:
The clock is built around a PIC16F84 microcontroller from Microchip. I chose this microcontroller since its FLASH memory is easy to program and assembler and programmer software is freely available for GNU/Linux. It has 13 general input/output pins which is just enough to implement all the feature I wanted.

This is a rather simple project. Cypress Semiconductors manufacture a microcontroller called CY7C68013. It is based on a 8051 processor, and has a lot of special functions and built-in peripherals, the most interesting one being its USB interface.This project is supposed to result in a CCD camera for astronomical purposes. developing software for the controller is VERY easy. The code is written on a PC, then downloaded to the CY7C68013’s internal 8 kB SRAM through the USB interface. No hassle with EEPROM burners or slow Flash memory.[more]
