A weblog focused on interesting circuits, ideas, schematics and other information about microelectronics and microcontrollers.
Build your own laser display by two mirrors, two motors to move the mirrors, a laser pointer, and a PIC microcontroller with serial input.
VGA 640×480@60Hz output from PIC with 64×40 pixels and 256 colors
Low cost and easily implemented sensors for homebrew robotics projects.
Cheap AVR-based frequency counter by Ulrich Radig.

module by implements Microsoft's .NET Micro Framework. This allows users to run C# managed code right inside Embedded Master. Users will use Visual Studio to develop and debug programs.
Based on a simple basic Idea, this proximity sensor, is easy to build, easy to calibrate and still, it provides a detection range of 35 cm.
This article shows how to use an use an accelerometer as a mouse. The project uses a MEMS X/Y accelerometer, a PIC microcontroller and a old mouse. It also describes a trick for powering the new mouse with the unused RS232 serial control lines.
Very simple version of the DDS synth, using just the Atmel AT90S2313 and a resistor network.
Freq meter with 7segment LED display based on the Atmel's AVR90S2313 and three 74HC chips by
