    Make Your Own Hi-Def Speakers

    This past weekend I stumbled upon a very interesting DIY video on making your own HD speakers for under a dollar a piece.  The full speaker consist of only a paper plate, foil, shiny penny and a mini-jack cable (and a piece of small tape). 


    The four simple steps are listed below:


  • Wrap foil around a paper plate.

  • Place a penny on the center of the plate. ("It is important to note that you use a shiny penny for this, as a corroded penny will increase electrical resistance which will result in poor sound.")

  • Tape the exposed wiring on one end of a mini jack to the penny on the plate. )

  • Plug the cable into an audio source.

  • (Granted you cannot make these speakers for under a $1 if you go out and buy the mini jack adapter, instead of buying the mini jack connector,  find your old Walkman (some old head phones) and use that)


    You can go here to watch the video yourself.






    Edit: What I thought was odd was, I found this video on YouTube just playing around this weekend and then today was searching for news ideas and came across the same video.

    Did you see this on mythbusters, or check out the whole video on youtube, reason I ask is because this idea was busted on the program and also acknowledged at the end of the video. But I guess you're really not out anything when it doesn't work, you can put the penny back in your pocket and still use the paper plate, and put the mini jack back on whatever you took it from. Just please do not buy the mini jack as I believe you will be dissapointed when nothing happens, if you actually put money into it.

        Looks creative. Thanks jmet.

        Wasn't you that had an idea about extending a router or something like that?

        It's great to see you back on, at least so we can see you.

          Just on mythbusters they proved it not possible to work. IMHO no way possible for it to work, except to blow up your audio card. Since there is no positive or negative terminals there is no way for this to work. A speaker needs a coil and a magnet to make the cone of the speaker to move.

            you can extend the wireless range by using third party firmware for selected routers... or can make wirekless repeater out of ur own crappy old router.
            Seems like as soon you buy somehing, v. 2 comes out 1.5 times as fast!..!

                No I didn't actually try it, but the key components of a speaker are missing, the voice coil and a magnet to react to the electrical impulses on the coil.

                One I have tried is with a styrofoam plate, magnet, and coil wire. This one works, but only as an experiment, it will not actually produce the sound quality to replace your speakers, but will give the basis of a working speaker.

                    Sounds like if you cut down the foil and used a toilet paper roll instead of the plate you might be able to make a kazoo anyway.

                      Yep...I used an old router as a wireless repeater and/or bridge using third party firmware (DD_WRT) and a Linksys WRT54G or WRT54GL (can't remember exact model) router.

                            (just the word itself looks illegal don't it?)
