Re: Rule against Sirens?

As David has pointed out there is no rule against a noise source in the DS, however, do you really want to risk distracting your alliance partners?

Rumble paks are easy to reverse engineer to work with a digital out (heck if convicts can figure out how to make tattoo guns with them, then it shouldn't be too difficult for a young engineer).

Team 78 uses something very similar, we've used modified logitech dualshock 2 controllers for the last two years. The logitech dualshock two controller is the same model as the standard controller provded with the FTC kit of parts....only with a rumble feature. Last year we simply rewired the motors that controlled the vibrate inside the controller directly to the digital output of the DS and controlled it accordingly, but this year it required the cypress board to achieve the same effect.

By using the can bus on our jaguars we can monitor the current our vaccum is drawing and trigger the vibration motors when the current drops (when we have a ball in our possession). As a driver its particularly helpful when going for the balls that are against the bump nearest to me, which I can barely see.

Driver should be looking at the robot, so we put a light on the robot, activated by a vacuum switch on our ball sucker.

Vacuum switch is fairly inexpensive, and commonly used on high efficiency home furnaces.

With a 102db buzzer, I should think that your biggest problem would be your alliance partners beating you with their control stations.
