Has anyone connected the Phidget to a dead strip ?
The dead strip does`t seem to generate the required 4V-30V power pulse. It works find with a 9V battery.
How do you guys go around that ? - Amplifier ?
How much voltage does a car generate ?

hi
in my club we used phidget 16/16 with dead strip for detection and pit stop in and pit stop out, And for the start light (5 red 1 green)

at the beginning detection doesn't work and to solve the problem we have placed a relay between track and phidget.
like that the car is only used to switch.
just use power supply 5v to activate the phidget and that works perfectly.... never lost lap or pit.....

Thats a good idea, that would have worked also.
I ended up building 4 operation amplifiers, to host the signal, took about 2 hours to solder together and parts from radio shack. Works great.

Thanks.
