This is rated at 100 db but with the same voltage requirements. It's a little larger, but waterproof and might give you the volume you need. Universal 10-24V 100dB Waterproof Back-Up Alarm - $11.49 It's made to serve as a backup alarm for trucks. The bracket might have to be modified to fit correctly, but it definitely looks heavy duty. The size is listed as: 2.4 x 1.7 x 2.7 inches, so I'm not sure if it will fit... It won't fit, unless you drill a hole in the side and stick it out wich could not be a bad idea.

Planemo Posted February 10, 2020 Share Posted February 10, 2020 (edited) Whats the volume like on that big one? I would be unsure whether the stock output would be enough to drive it. I moved the stock buzzer through the case. Much louder and I havent yet failed to hear it at top speed. And thats wearing a full face lid too. I do still need to try it in a strong headwind though.

The oryginal one HYT-3015A is rated 90dB at 10cm, and the YUESONIC is 100DB at 120cm so in teory it should be more then 10x louder but in practice it seemed 2-3x max. I guess it's normal hearing works in logarithmic scale too YUESONIC is waterproof but it's not continuus sound. I think I'll install it on the front of the msx using velcro, guiding the cables through the ventilation hole, and driving it using a relay, a buck converter and a mosfet.

I wouldn't connect this buzzer directly to the board either way. Fast circuit from paint just to show the idea: That way the on and off sound would be beeped only on the internal buzzer, all other beeps would activate both buzzers. Having a nice DC converter would also allow to install custom high power lights controllable together with the internal ones. (I didn't measure anything yet so this circuit my need some modifications) Edited February 11, 2020 by fdmalchemist 2 Quote Link to comment Share on other sites More sharing options...
