light weight Buzzer for micro quads |
Found these buzzers on ebay, weights only 0.8g each, should be good for micro quads either lost model or voltage alarm (brushed or brushless) http://www.ebay.co.uk/itm/152078153535 02-Sep-2016, 09:17 PM I bought a swag of them a while back and are ideal for micro sized quads, They are not quite as loud as a full sized buzzer, but still better than no buzzer at all. You can however boost it's sound by using a 12 volt rail on the power as on most FC's the negative buzzer pad is the signal/trigger for the alarm. (of course make sure your buzzer supports up to 12 volt (which these do) 02-Sep-2016, 09:32 PM (02-Sep-2016, 09:17 PM)BigglesFPV Wrote: I bought a swag of them a while back and are ideal for micro sized quads, They are not quite as loud as a full sized buzzer, but still better than no buzzer at all. Good tip, I didn't think of that! Often it would be useful if it was a bit louder |
