Replace the Knob on Your Car Radio for $.01





Introduction: Replace the Knob on Your Car Radio for $.01

About: Well, I am mostly a family man, which means I use "hanging out with the family" as an excuse to get less of my projects started, and a fraction of the started ones finished. I try to be passionate about wha...

Conceived and photographed at red lights on the way to work. The knob was missing on my car radio when I inherited this car, and it is really annoying. When I scrapped an old CD player, its knob popped off while I was carting it around in the car. I got this idea when the knob rolled under my feet.

You will need:
A radio missing a knob
A knob from another useless device
It is best if the knob has a slot in it
A penny


Step 1: Insert Penny Into Knob

If your knob does not have a slot in its post, you could possibly create one, or maybe use an epoxy.


Step 2: Insert Into Radio Post

Now you insert the penny & knob combo into the slot in the radio post.

That's it! You're done. Enjoy your much more comfortable radio.

    The bigger the knob, the bigger the boom. And, I bet it goes all the way to eleven! :)

    all blaupunkt radios have knobs that can be turned to infinity

    Mine turns to infinity +1. The tuning knob divides by zero and produces a rational number. Such is Blaupunkt. And yet, the damn thing still keeps killing lights in the faceplate!

    I've actually frequently used a penny alone in the past, never thought of using it as an intermediary for a different kind of knob. Well done!

    The MAC-Daddy of all radio knobs! I love it and the simple ingenuity of adding it on with a penny. The penny is probably less expensive than any other device used to "convert" the knob!

    they get cracks as the plastic ages,then it falls off and rolls under a seat when you hit a bump in the road

    What is the purpose of the penny? I would think it would be a cheap washer spacer, whatever), but I doubt you have a drill in your car.


    wow. this is pretty ghetto
