Hi Annika,
We have used this USB controller in some experiments, interfaced with eprime (by way of keyboard emulation)

Hi Emiliano,
Thank you very much for your response to my question. The device you suggested sounds exactly like what I've been looking for and it's quite affordable, too. Just two more quick questions if you don't mind:
+ Does the button turn "endlessly" in one direction or does it stop at some point?
+ How are your experiences regarding timing accuracy?
Thank you and best wishes,
Annika
I've had nothing but good experiences with the Phidgets corporation: http://www.phidgets.com/
This rotary potentiometer is continuous and fairly cheap: http://www.phidgets.com/products.php?category=37&product_id=3583_0
One other great thing about Phidgets is that the control board you'll need for the potentiometer can be used with almost all their input/output devices. In essence, one control board purchase is all you'll need to able to collect multiple types of data is the need arises.
Hi Jakob,
Excellent ideas, thank you too. That sounds like something worth looking into. The price is very reasonable, too.
Best wishes, Annika
Sorry Annika, I did not see your reply...
It turns "endlessly" and I guess that timing accuracy is the same as what you can expect from a usb keyboard.
Good luck
