1-key 'keyboard' for controlling aux music playback in my car

[Plasmodium]

Ok, so it's not really a keyboard, but it's an input device and it uses a Cherry switch (fine, a Gateron).

Basically I just re-bodied the inline controls and mic from an Android aux cable into a chunky, easy to use format. My stimulus was the recent UK traffic safety laws which mean that newer drivers (like me! ) could lose their license if they are caught using their phones in the car. I like to play music on mine, but I also want to drive safely and within the law! So I made this gadget to easily control playback without picking up the phone. It was just a bit of a fun project for me last weekend and I figured some of you Deskthoritarians might find it interesting.

Here's a link to my more detailed (and perhaps rambling) write-up on my blog, and I'll post some WIP pictures below!

The insides of the inline aux cable controls. One pushbutton and one mic. Both wired to the 4th pole on the phone end of the cable.

The inside with the phone end wired up (but not the stereo end yet). Some slightly janky soldering was involved, but it all works!

Finished and in-situ!

The little beanie baby penguin is called 'Dippy' after the genus 'Eudyptes' of crested penguins. My mother gave him to me at Christmas to 'keep me company on long journeys'. But he is quite cute.

Cool little project. I've thought about hacking the preset buttons on my stereo and adding a panel with mechanical switches for better ease of use
