APRS tracker & automated camera with an Android phone
KF5JSJ has created a new app for the Android. This is a project for an Android phone that takes pictures and broadcasts the phone GPS coordinates using the amateur radioAPRS infrastructure. He is using it as a backup tracker for a high altitude balloon project but it can be used for a couple things such as setting in one place and storing time lapse photos, or keeping track of where the phone is graphically on a map.
