Following Chris' post about the dronecell, here is a first use i've made with it.
I combined a GPS, which is being read by a PIC controller, every X seconds, then every 5 readouts it will send the last 5 readings over SMS text message to my cellphone.
The idea is to create a small and compact device, with autonomous battery (that can be optionally charged off the main vehicle's battery) that will help you find your drone in case it gets lost or crashes.
i've not yet tested the battery life, but it should be holding for a good few hours.
i call it the Black box, though it's not the same as the traditional one...
super thin design - only 16mm
I've took apart the stock connector and antenna, both SMA connectors are very heavy !
here they are connected together and heatshrinked:
for a total of 63 grams !
I will be really liking this one, next time it will find my copter when getting lost,
after i lost a full quad arducopter in a forest, couldn't find it till today....
What i like about it, that it has the autonomous battery, and the quite-infinite range of a cellular network.
it will tell me where it is even when it crashes and the big battery get disconnected and thrown away,
even when it is out of range of my radio, my telemetry etc...
and even if, let's say, it gets stolen !
I just get an SMS on my cellphone with the 5 last points, including exact time longitude and latitude of each point.
