In this semester project we tried to develop a multimedia kiosk system that is easy to configure, easy to maintain and easy to use. We used a central server and multiple diskless ("dumb") clients. These clients load all data from the central server using techniques like PXE and TFTP to bootstrap the system, NFS to transport data as well as programs, a HTTP interface and a browser to display the content to the user in front of the kiosk.

The content can be changed by a user friendly CMS and the kiosks are configured on the central server by no more than 4 configuration files. Maintenance of the clients and the server can be done on the central server. In order to reduce the risk of this single point of failure a backup strategy and tight security is enforced.

2004: Implementation of a Bluetooth Stack for BTnodes and Nut/OS Version 0.9

Mathias Payer: Implementation of a Bluetooth Stack for BTnodes and Nut/OS Version 0.9

Abstract:

The target of this semester thesis was to develop a modular Bluetooth stack for BTnodes. BTnodes are microcontrollers with very low computing power and memory and have a Bluetooth controller attached.

The main target of the stack is to ensure communication between diﬀerent BTnodes. This leads to the implementation of some speciﬁc layers of the Bluetooth speciﬁcation.

So the stack was implemented with BTnode constraints in mind, like speed and memory usage. The main diﬀerences to the old implementation are that this new stack uses threads, has a modular design and uses a sequential programming schema.
