Introduction: Tennis Ball Stereo (TBS)

A mono stereo made out of an old mini radio, a tennis ball and some 99 cent headphones , bye the way this is my first instructable so sorry if it sucks. Sorry for the fuzzy pics.

Step 1: Materials

Materials

Head phones
A tennis ball
a speaker about the size of a tennisball

Tools

Hot glue gun
a very sharp knife
soldering iron
solder

Step 2: 1. Cut the Tennisball in Half

this is pretty obvious, just take the knife and cut the ball in half

Step 3: Stereo Part

take the 99 cent head phones and cut off the speaker part. then strip the two ends about a centimeter from the top. Solder one end to the plus side an one to the negative side.

Step 4: Glue the Speaker Into Case.

simple as that, now you have a mono stereo out of a tennis ball good job!

huh? What have you used in the end prodict for the black bit? How is it all attached? There is a mental blank for me as to how you go from step 3 to 4. Where is this plus side or even the negative side. What object are you talking about?

i think he means take the radio and solder the radio t o the  headphones

Really cool! How does the sound work? Is it listenable?

when I try to hook up the speakers, the speakers don't emit a sound, can anyone help me?

what speaker is that ? watts ? ohm ?

does it matter?

yeah i just cut a slit into a full tennis ball and stuck two speakers in it then seal it back up...so its just a tennis ball with a headphone cord comming out of it...kinda quiet but pretty sweet...ill make an instructable on it some time

i was ganna say that when i saw the picture!

can you explain step 3 a little more clear? i don't really understand.

hmmm i may try this with a set of old cd player speakers i have sitting around
