Virtual Knobby

Happy new year! We have plenty of exciting Scanbox developments happening this year, so stay tuned to the blog.  You don’t want to miss anything!

We recently introduced a wireless version of knobby that runs on Android tablets. The same software is now available to run on Windows, side-by-side your Scanbox application.


The controls and behavior are identical to the tablet version.  To use virtual knobby simply set the tri_knob configuration variable to “”.

After launching Scanbox from Matlab go to the yeti/knoby_virtual/ directory and launch the knobby_virtual.exe application.  That’s all…  Go ahead, give it a try!

So you now have three options for position control: classic knobby, knobby tablet and virtual knobby.

Note also that if you are a user of classic knobby and run into some issues (like a rotary encoder going bad) you can always use virtual knobby as an emergency replacement while the hardware version gets fixed.  So no more downtime for a broken knobby.
