This ATmega644-based project implements a touchpad input system which takes user handwriting input and converts it to a printed character. Currently, the device only recognizes the 26 letters of the alphabet, but it could be easily generalized to include any figure of completely arbitrary shape, including alphanumeric, punctuation, and other symbols using available training system.

The aim of this project is to build a wireless 2×16 character display that fit to Altoids tin. It can be used to display data which is sent from the PC using a terminal program such as the Arduino ‘Serial Monitor’.
The project consists of two main parts, first, the ‘remote’ Altoids tin containing Arduino, LCD [...]

The purpose of this project is to build a device that can keeps track of the score and which team is serving. Mounted on the edge of the ping-pong table, the device speaks to you – scores and service are announced verbally. They are also displayed on the LCD.

The ping-pong score keeper is built using [...]

Aurora 9×18 is a beautiful firing sequence of 162 RGB-LEDs in a circular configuration. The color of each circle is controlled by a microcontroller (PIC24F08KA101) using a twisted form of PWM. The MCU only has one PWM module, yet Aurora is capable of 27 (9xR,G,B) independent brightness control.
