Car Radio at Home




About: A man who does not like to get bored.


English is not my native language and this is my first post here so please for your understanding.

Have you ever wondered what you can do with your old car radio, laminate flooring, a handful of electronic scrap and a few trinkets?

- Maybe ... home stereo? Why not.

I needed:

car radio
old computer speakers,
mains transformer (12V)
power supply,
any idea on casing
and some electronic scrap.

Putting it all together I received the effect of the images shown.

(Internet address shown on the pictures is outdated - I moved the blog after another one.)

    I once had an old boombox with a working power supply and good speakers but the cassette player died. Since I also a car FM/cassette deck laying around I decided to put them together. I cut holes in the top to fit the shafts and the dial, installed the deck and hooked it up to the speakers, antenna and power supply. Worked very well.

    Cool idea. I have done the same and have built car stereos into many locations including my garage workbench. The power supply is crucial and must be capable of supplying 12 filtered DC volts and up to 10 amps. If lucky you can find a plug in power supply with these attributes from scrap computer parts. If so, you have good cheap stereo alternative!

    Thanks :)

    My power supply provides 13.8 V - that I set by potentiometer.
    From the observations I know that 10 amps is not always required. This current yield is indicated when the radio has some engines (tape, CD).
    My radio gets about 0.5 A with connected computer speakers (and without them too), and the power supply has a capacity of 3 A.

    Neat idea. When I lived in Italy, we had a club house and used a car stereo, powered by a 12V battery. We made due with what we had.

    I do not have pictures step by step. But I build another device for a friend and there will be a complete description with photographs. Then I will present.

    I can only add that the power supply is made on the integrated circuit LM350. (

    electrical scheme: )
