Raspberry Pi

Things we done

We took it apart and got the speaker to work. played show me the body, was good.

11 (Neg), 12(Pos) speaker output

Then we tried the microphone but its carbon and it didnt work. so u atttached a batery and hoped. didnt work

We took apart wired headphones that had mic in them to see if we could use the mic from it rather than the carbon mic in the telephone.

didnt work, headphone calble is trrs not trs:

spent a day trying to wire up trrs to an audio cable, turns out the audio jack was the wrong kind.

then wired it directly to a trs jack, worked!!!!!!!!

then cable managed, looks beautiful now. now we have working speakers and working mic.

This is how you could make it work too:

From the headphones you need to...

Connect th Blue (Ground) to the Sleeve of the TRS jack

Connect the Red (mic) to Pin (Ring) 1 or 2 of the TRS


next steps:

work out how to read the keypad input on the raspberrypi.
