Hi everyone I am an engineering student and an athletic training intern. I work with a lot of college and highschool athletes and often run sprinting drills with them so I tried to contstruct my own fully automatic timer system using photogates. The Relay I used is shorting out the lap timer connection right now jamming the stop watch I was wondering if any of you can tell looking at this circuit if I have too much power going to the relay and need to thin it out with some resistors before I put a new one in or did I just get a lemon relay. The Voltage source is two 9v in series, R1 is a 100k ohm resistor, R2 is a cadmium sulfide photo resistor, transistor Q1 is an 2N4401. Thank you for your time. http://youtu.be/7XxLl8ZZyDY
