Hi Guys, I wondered if I could pick your collective brains please?
My brother has four fishing bite alarms (in which the line runs through a roller, and when the rollers turn, the PCB makes a speaker squeak). He's looking at fitting them with a remote speaker (there's a headphone jack at the bottom of each one), and was wondering if there's a way of running them wirelessly.
My initial thought was to have a 3.5mm to Bluetooth transmitter for each speaker and a separate BT speaker. However, with each unit needing charging, it will mean charging eight batteries at a time.
My second thought was to use four audio leads and connect them to the D-Pad +ive and -ive terminals on a broken USB gamepad controller, which would then interpret them as completed inputs, and would then be picked up by a Raspberry Pi then play the specific rod number from an MP3 file to one Bluetooth speaker. The Pi could get its power supply from a USB powerbank.
Now, I'm sure this could be done, but I haven't got the faintest how to do it because I don't know the Pi's programming language. Can anyone help with the nuts and bolts of this, and also how to make the programme load on booting of the Pi please?
