Sorry, but Gryoscopic accuracy for gaming applications is Crap. If you want to play a game like crap, why even bother to build a specialty controller?
You will have lag, and inaccurate drunken response. Which is why I cant stand to play gyro games on a phone.
The Twisty Grip not only looks bad, but its nearly impossible to get it to calibrate in windows. The reason, is because it does not use enough pot travel to even register properly... because it has no gearing. Also, as a result, the resolution is very poor, resulting in poor control results.
I dont remember any springs in the handles either. And finally, the switch-buttons it used were horrible feeling.
I had a proto, which was pretty much the final design.
Making a Yoke isnt an easy task, but its possible to do.
The usual issue is that the end result isnt as good as the real deal.
One day I might give it a 2nd shot, improving the spring return mechanisms.
