Tbh I've been really busy, not had much time to fly anything and with conditions being crap, hopefully in the new year I'll have some new projects on the go, mostly to do with HAM radio, will certainly fly again soon. FTR I hate FB too   :D Merry Christmas

Rocket Locator Android app

Anyone tried this Android app system? www.rocketlocator.com
Seems to tick all the boxes, and the rocket guys should know because they loose their stuff every time they fly!
I loaded up the app and it looks well designed.
Unless I find a bad review I';ll start on the hardware.

not yet Yorrite... but i';m gunna.

Cheers for the post, It could be a fun test (or just an all out disaster!)

I';ve just found the parts and made a lash up of this locator and it';s the biz.

One GPS module from a defunct OSD
Pair of APC220 radio modules
HC-06 Bluetooth module
Couple of voltage regs

All parts bar the GPS from AliExpress for pence, and software for free.

Tha app is ultra cool - the pocket unit links to your phone using the bluetooth and homes you in on your lost item using a line drawn on Google Earth and sonar beeps! Also can log flight data (altitude etc) and stores the last recorded postion when/if the signal drops out.   

I';ve only made a lash up using breadboard etc so far, and not tested the range - but los the APCs are supposed to be good for about 1200m.

Concept is proven so next comes tidying up into air and pocket packages, then proper testing.

Gravity will prevail.


I just found a smaller GPS unit - so the air part will be slightly smaller than a PP3 battery and weigh perhaps 20gms (not sure how accurate the kitchen scales are).
Will run from the flight battery so no extra weight there.

I';ll be making one to go in all my toys now for sure.
Got the other stuff but just need to get some more GPS units.
Prices on Aliexpress:
Bluetooth HC-06 at £2 each
APC220 pair at £20
GPS at £8
Voltage regs less than £1
Gravity will prevail.


Air unit tidied up now for easy fit in a 250 size quad.
Gravity will prevail.


@Yorrite, That';s fantastic  :notworthy:

I haven';t even started to even think about checking it all out, but I really want to.
Do you have a ';blow by blow'; log of what you did to get to your final result?

I';ll just have to read your account and dream until I can find some free time.

Thanks mate


I could do with a build lof too after nearly loosing mine the other day was only luck i ended up within bluetooth range 1/4 mile away in thick woodland from where it started off
