This project resulted with a simple distance measurement tool which uses an AVR at the core along with and LCD and ultrasonic sensor.
The developer wanted a bar-graph and plain text to visualise the distance to an object, and include a "tare" function so that predefined distances could be added/subtracted to the result based on the tare distance. The source code, construction and interesting highlights are discussed in his article. [via]
