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]

This is a simple G meter project,it’s suitable for mounting into a car. It displayed the amount of acceleration in units of g whenever the car was accelerating or braking. This project is suitable for anyone experienced in developing for an analog enabled microcontroller. [more]

Alex writes:BlinkM is a smart LED, developed by Tod E. Kurt from ThingM. In a way it is a cousin of the Programmable LED. It is a microcontroller with an attached RGB LED. The idea is to implement PWM to control the color and brightness of the LED and put it in the controller. That means you have an abstraction level to make your programming easier. You can simply order “fade to red” or “fade to blue”.[more]

In this lab, you’ll control a servomotor’s position using the value returned from an analog sensor. Servos are the easiest way to start making motion with a microcontroller. Even though they don’t turn 360 degrees, you can use them to create all sorts of periodic or reciprocating motions. Check out some of the Flying Pig mechanisms for ideas on how to make levers, cams, and other simple machines for making motion.[more]
