Atmel

Monster Memory - 512kB DRAM with AVR

Jesper Hansen's method to connecting DRAM with an AVR microcontroller.

BitESC - motor controller

The BitESC is a small electronic speed controller for those little RC cars like the MicroSizer / BitChar-G. It can be used in a small RC plane to have some control over the speed of the motor.

AVR Accelerometer

Jesper Hansen's accelerometer named AccelR8 based on Analog Devices' MEMS chip

Positional Sensor Interface

Low cost and easily implemented sensors for homebrew robotics projects.

Simple functions generator

Very simple version of the DDS synth, using just the Atmel AT90S2313 and a resistor network.

Frequency meter

Freq meter with 7segment LED display based on the Atmel's AVR90S2313 and three 74HC chips by Jesper Hansen

Password generator

Convert an AVR development board into suitable password maker.

ATmega8-based video overlay

Simple video overlay circuit, built on breadboard? Yes!

Electronic lock with iButton

Today I've found this interesting circuit, which In use Dallas/Maxim's iButton as a key to an electronic lock.

AVR XMEGA

The new Atmel's microcontrollers has been introduced - AVR XMEGA.
