I come to you with hat in hand after doing something rather foolish. While trying to install an FPV transmitter inside the iris housing, I seem to have knocked loose the ground wire leading from the pixhawk autopilot to the buzzer. The soldered connection inside the buzzer itself has come off. As I never put any pressure on that particular connection it looks like it was pretty poorly made.
I have several questions regarding this:
For now, can I simply fly without a buzzer attached to the pixhawk until I can order a new one? (I’ve tried to remove the buzzer plug from the pixhawk itself but can’t seem to get it out and don’t want to risk damaging anything further).
Can I order a replacement buzzer from 3DR or will any buzzer I can pick up from radioshack do? The only suppliers I can find for this particular brand of buzzer seem to be outside the US.
Lastly I would prefer to try and repair the current buzzer, as the problem is very simple. As I have little experience with circuit design, I assume the ground wire leading into the buzzer was soldered to a specific place inside the buzzer to begin with. Could I simply solder the ground back onto the buzzer and then test it while not connect to the Iris?
Thank you for any insight.
