I'm planning to start a new project soon, based on this display and use it with VEMS:

Or from another manufacter: http://www.hy-line.de/en/firmengruppe/hy-line-computer-components/hersteller/primeview/
Using one atmega128 prototype board serving as a graphic unit.
The hardest part will be writing the code, but a great opportunity to develop my programming skills!
Does someone want to join this project? :)
