Trying to find the problem I opened the whole collar,
and finnaly realized it was a matter of battery :P
tinkering
Electronic – attaching electronic to the collar
The collar
Handeling the size and weight
Using “heat sheath” to protect circuits
Sound wasn’t good enough therefore I rebuilt a speakerbox
Electronic, fail – bluetooth burnt
Electronic – Noise reduction
I had to use a coaxial cable between my bluetooth handset and the audio amplifier to reduce the noise made by the mobile phone waves.
Problem:

Solved:
Electronic – first tinkering
Bought a bluetooth handset,
Opened it,
Wired a very first version of my circuit,
Power supply + sound amplification + big speaker,
Testing the bluetooth connection to the phone.
Thanks to Théo Reichel, technology superviser.
