dont forget the algopic: https://algo.mur.at/data/projekte/algopic/ for Autoklavierspieler ;-) used serial-interface for better timing, this was the reason for (comport - external).

PS: just designing a new one with ethernet, since timing is criticalm, open hardware of course.

Don't forget one of the cheapest interface, the USB Bit Whacker DIY, http://wiki.dataflow.ws/Interaction/Interfaces/UBW official web http://greta.dhs.org/UBW/index.html and sold 19 $ at sparkfun = 12 euros....

and the GNUSB http://gnusb.sourceforge.net/hardware/

the USBDUX http://www.linux-usb-daq.co.uk/

the CV to midi http://www.fredrikolofsson.com/pages/hardware.html

the interface-z http://www.interface-z.com

and many others... I have collected about a hundred different low cost interfaces links for interactive creation for the CRASlab activities, and I would really like to have the power to compare and document all this interfaces in terms of cost per input/ouput, open hardware, latency, protocols, DIY possibility and time, components availibility in the world, recycling, power cunsumption, etc, to complete http://www.sensorwiki.org/index.php/Sensor_interfaces

but we have just money for making one USB Bit Whacker, wich is one of the best !
