Tangential post:
I've recently installed oldschoolbob 's drop target sensors and have them working nicely. They drop, reset, score and make the sounds they should. However, I noted something that I thought was anomalous to my machine.
When a non-lit drop target drops, it scores what it should (2000) and make the score sound. However, when a lit drop target drops, it scores correctly (5000), but makes a 'red noise'-like sound before making the scoring sound. It does this for the red and orange sets.
Now, I thought there was something peculiar about my machine that I thought I'd have to trace, but watching some Blackout videos on youtube, they do the exact same thing. I'll attach a video below - skip to 9:00 (I've tried to link to that time) and listen for the sound when the right-hand lit orange drop target drops. That low-frequency 'hiss'.
Does everyone else's make the same sound? If not, how should it sound? (In which case, how would I go about fixing it?)
Thanks!!
