Waterproof bike alarm out of ABS

  1. Nov 28, 2004 #1
    :grumpy: I have made a case for my bike alarm out of ABS. I have drilled holes to allow sound from the buzzer to come out. Now, the problem is, if it rains, my alarm will get damaged because the water would flow through the holes into the circuit. The ABS is waterproof already, but how can I prevent the water going into the circuit without blocking the sound from the buzzer? :confused: :grumpy:

    that would not be good idea because the tape would come off
