Description

I wanted to use my BF-F8 for a fox hunt, so I needed to attach an Arduino and power it. The backpack slides onto the grooves in the back of the battery meant to align the battery with the charger. There are 3 contacts on the back of the battery used for charging. They expose the full battery voltage (2 cell lithium) so I'm using that to power the Arduino.

As a future improvement, I'm mounting a GPS (ublox neo 6m) it the backpack as well. Initially the fox is going to be able to it's callsign and GPS position out with morse code. Later, I want my radio to transmit APRS info. I've always wanted to have APRS in my car.

I'll be filling out more details including build instructions soon. For now, I just added a GitHub link for the initial code. https://github.com/timogiles/ArduFoxGPS. Stay tuned for more details!

Hi, do you have the circuit diagram? Thanks

Are you sure? yes | no

Hey Tim,

Have you been able to get this working? How well does the ublox neo 6m work? Any other updates on this project?

Thanks, Ken

sorry, but I am not getting why have you put an Arduino on it, can you please explain..

recently got these Baofeng radios, was looking here at Hackaday what others are doing with them... other than using as they are intended to be.

Are you sure? yes | no

Good question. I'm connecting the arduino to the the radio so that it can cause the radio to transmit and send audio. And by audio I mean square waves. I have linked to my code that will cause the Arduino to transmit morse code messages which is useful for fox hunting. I need to come back and put more information here because it works very well.

Are you sure? yes | no
