Introduction and motivation
• Standardisation trends address high-end solutions
• Embedded internet modules offer low-cost alternatives with increasing performance
• Previous workbenches based on low-cost modules proved to be feasible

Conclusion
• Client and server code for the two workbenches is available as open source modules from Google code
• Performance is far superior to our previous solution based on Maxim-Dallas TINI® network microcontrollers at ≈ same cost
• The same AP7000 Base board can run multiple experiments simultaneously
