Building TILT detectors for Visual Pinball?

<< < (4/5) > >>

patrickl:
I once built a tilt dongle for my Palm Vx. This uses a 2 axeis accelerometer. See Tills Palm Pages
for schematics. These have two axis so you can detect both a front bump and left right bumps. One nice thing would be that you could configure how sensitive you want the "nudge" to be. You wouldn't have to tilt the cab a whole lot for the tilt sensor to still register your nudge (as with mechanical switches).

You would need some translation electronics and as I recall these sensors are not cheap either.

Sorry but a tilt "bob" with 3 seperate detections is NOT going to work! It will often swing, make contact with one side, then swing back and make contact with the other side! I'd even bet it could sometimes make contact with all three sides before it slows down enough.

And I agree that rocking a video cab is a bit... uh not a good idea, nor is it as easy to do as a pinball machine.

so make 3 seperate bobs - that are only limited to one direction each.

 imagine this...  

 a steel marble sits in a plastic tube.  the tube is slightly angled upwords... and at the end, has contact points - or a switch.

 when shaking the machine... it will roll the ball up to the contact or switch... the roll back down.  

 believe it or not - shaking a machine isnt that hard.  ive witnessed it a lot when i worked at the arcade.  
 
 however... one could make a seperate lower mini pinball panel that was mounted in such a way that it pivoted a bit - using rubber surround to return it to center... and the above switches for nudges.

patrickl:
The point is that that ball will bounce around and "click" both left and right switches (perhaps even several times) if you nudge the machine sideways (hard enough).

Oh wow.  Sorry for hijacking this thread for a second, but with that tilt dongle, does that mean you could set it up to make noises a-la Ziggy on Quantum Leap?  ;D

Oops. Sorry. I"ll take off the geek-hat now. :)
