I have two cheap chinese so called bite alarms. They are only good for shark fishing because normal size fish can't trigger the alarm. Even cat fish couldn't.
So, I'm think of creating a simple carp bite alarm. I stuck on the sensor part. What would you recommend? PC mice rotary encoder is not good for this. To use a reed sensor the cercuit needs to be modified, which I don't want to mess with. Any other ideas? Thanks.
