“This week I want to build an audio and light beacon for my final project. My high elevation baloon tracker sends its GPS position by radio and by SMS, but for example if you land in a forest, the GPS can be innacurate and have an error of 100m or more, so it can be difficult to find the device if stuck on a tree or a rooftop, etc. So I want to build a device that when the tracker lands, outputs some sound and light to help finding the tracker.”
