Every once in awhile I’ll post a design that strikes me as a no-brainer, like this or this. I’m very surprised there hasn’t been any K.I.T.T. car stereo decks made commercially or as fanmade/homebrew projects even.
This design would be encapsulating the K.I.T.T. dashboard into a stereo deck which would feature its namesake as a music visualizer – pretty straightforward. Originally I had a normal volume dial, but for fun I used the steering wheel instead, something that wouldn’t be too practical for an actual stereo deck.
Just like the last stereo deck I designed, this design discards the CD slot on the front, so if you want to load a disc the face will have to flip down (if CD capability were included to begin with).
One touch I’d like to include are voice greetings from K.I.T.T. when powering on and off the stereo (“Hello, Michael.”), and the Knight Rider theme on command.

That blue bar that shows how much time is remaining on the track….it would be HOT if you could change that to be like the red scanner on the hood of the car.
Unfortunately the timer is really static, so KITT’s iconic red light would be kneecapped here.
The red light should be used as a security light when the faceplate is gone.
