Hello! Since I am a big rlectronics hobbyist or wtv how you spell that lol.I was wondering if there was anyway of making something small and loght weight to be able to find your drone when it was stuck in a tree or bushes or even a swamp if you know the general location and not 5km away.So i made this.Very cheap and very easy. 1x arduino nano 1x 4 channel rf 2x cellphone battery (cheap on ebay) 1x charger cellphone battery. And i think i will just glue gun it to the battery for now. Basicly the way it work is that when you press the button on the rf remote.The buzzer start chirping very loud in a weird patter that can be modified easy with arduino! Since the band use is 433hz it not suppose to interfere with the drone and anyway it use to find it so no intention of using it while flying hahah.Anyway that was just a little something for a wednesday after noon. Matt sent from note 3.
