Introduction: LED Bouncie

This is my entry into the Get the LED Out Challenge.

It is a combination of the amazing LED Throwie by Q-Branch and your average super bouncy ball. The result is a bouncable light up device that is excellent for satisfying your midnight super bouncy ball cravings.

Step 1: Gather Materials

Picture of Gather Materials
Gather the following materials:
  • 1 Small LED (any color will do but I had green on hand).
  • Enough small button cell batteries to power your LED.
  • 1 Super bouncy ball.
  • Electrical tape .

And also fetch the following tools:
  • Razor blade.
  • Exacto knife (the razor will be fine but the Exacto will help you as well).
  • Hot Glue gun (and glue). The hot glue worked OK but you may want to use super glue or epoxy instead.

Keep in mind that you want all your components to be small. You will notice that my LED and battery arrangement fit comfortably inside a 1-inch super bounce ball. You can use larger components but you may need a larger ball to house them all. That said, lets continue.

Step 2: Dissection (part One)

First, take your razor blade and simply cut the super bouncy ball down the middle. You will notice that there is already a line running around the equator of the ball and it is a handy cutting guide.
I suggest using the razor blade in this step because it makes one single cut going straight down rather that a longer cut running around the entire ball (like would be done with an Exacto knife.) The result will be two completely hemispherical segments of super ball.

Step 3: Battery and LED Core.

Now to prepare the insides.

First, take your two batteries and tape them together making sure that the terminals are in order like this +||-+||- (where || represents the battery.) Be sure that the tape is very tight around the batteries and that the batteries touch each other, (pics 2-3).
Then, using an Exacto knife or razor blade cut the excess tape off the batteries and discard, (pic 4-5).
Now, test your LED on the batteries to find the positive and negative terminals so the LED will light.
Bend the leads of the LED so they conform to the shape of the batteries and then tape the LED on the batteries so it lights. Be very sure that the leads are taped in place securely because this throwie will be bounced around a lot.

Step 4: Dissection (part Two)

Now you must carve a cavity into both segments of super ball.
This can be most effectively done with an Exacto knife, razor blade, or a drill with a large bit on it. In one half of the ball you want a round cavity that approximately half of your battery assembly can fit in to.
On the other you want to look the same as the first except for a notch in the side of the ball that the LED can fit in to. (Picture 2 best shows the notch for the LED.)

Note: This step makes tons of tiny rubber particles so you may want to do this over some newspaper or something similar, (not your mom's carpet).

Step 5: Final Assembly

Now to put the ball together.

Put a small dab of hot glue in the cavity of the half of your super ball
with the notch for the LED in it. Then secure the battery assembly into the cavity being sure that the
LED is positioned in the notch as shown in pic 2.
Now you want to dry fit the remaining part of the
super ball over the part that was just glued. If it does not fit easily then remove more
material from the cavity and try again.
Once the top fits on the bottom, begin gluing. Slowly work your
way around the equator of the ball making sure the glue bonds well. Super glue will work here if you
are having difficulties with hot glue.
Trim off any excess glue as necessary, but be careful not to cut the ball.

I made one, but I had no glue so I used tape.

Ploopy (author)2013-05-09

I think it would be good if the LED was pointing down and not where the ball was cut in half. it could be use full if the ball brakes.

avanbibber (author)2011-08-21

Would this method by ok for making eyes on a halloween costume? Am making a werewolf and would like LED red light eyes.

elkalpin (author)2010-05-18

I'm ganna make one where one end of the led is connected to the battery, so when you thow it down it blinks once!

codongolev (author)2008-12-01

so many throwie remixes... bouncies sinkies handie any other -ie things you can think of.

Floaties and Frosties.

bassclarinet23 (author)2009-10-12

So I'm assuming that the LED is tucked in far enough that it won't break when it bounces. Is that correct?

How long, typically, does the battery last?

ampeyro (author)2009-06-17

a good version of this could have a impact swich(i must add it to my list)

timanator (author)ampeyro2009-06-17

you could probably find one on a small kids toy

garrett10 (author)timanator2009-07-18

or old flashing shoes

ampeyro (author)timanator2009-06-21

yes but the idea is to do it myself, if i buy the finished product it's not DIY

timanator (author)2009-06-17

where can i get a good LED light

canno (author)2009-04-13

will this affect the bounciness of the ball?

LEEROYJenkins (author)canno2009-04-20

i almost feel that using the word "bounciness" isnt quite professianal. but on the other hand it is a fun word.

marc92 (author)2009-04-06

It's only to improve their usability in the dark.

Letharius (author)2008-09-17

Nice Instructable. I think I'm going to try this one. In the end, how much is the uh, "bouncability" of the ball effected by the cutting in half, and gluing? Does it still bounce well, and fairly straight?

marc92 (author)Letharius2008-09-17

It does not bounce as well as if it was not cut in half, but it does still bounce.

bassclarinet23 (author)2008-08-11

Can you shut it off or do you just have to keep it on until the battery dies?

marc92 (author)bassclarinet232008-08-11

It stays on only because I did not have a small enough switch.

geeklord (author)2008-08-08

why didn't you use one of those super thin batteries, The 3volt lithium ones?

marc92 (author)geeklord2008-08-08

They are wider than the super ball itself.

geeklord (author)marc922008-08-08

O, i thought you were usin one of those bigger bouncy balls. The ones that are somewhere around an inch or more in diameter. Theres an idea...........

Artificial Intelligence (author)2008-05-28

Very cool. You could also try this Instructable by to make a super bouncy ball.

yeah that way u can make it without cutting the call in half then gluing back..

And you can make it in different shapes and sizes.

Great idea!

Thanks. This Instructable is a great idea.

cooldog (author)2008-02-11

you could use the switch inside those shopes that light up when your walking

marc92 (author)cooldog2008-02-11

Great idea, I wonder how big those switches are.

Pyrowuzzup (author)marc922008-02-11

you could probably even make one of those switches yourself. you would just need two thin pieces of metal that would be kept apart until and impact caused them to temporarily bend into each other.

cooldog (author)Pyrowuzzup2008-02-12

some guy that made the all-terrain wallet used one

check it out

marc92 (author)cooldog2008-02-13

Thats pretty cool but I don't think that would to fit into one of the super balls that I am using.

Shinji (author)marc922008-02-18

A thin spring with a pin in the middle. You can make it as small as you want.

Sandisk1duo (author)Shinji2008-04-21

they already have this, the lighted bouncy ball

Shinji (author)Sandisk1duo2008-04-22

Yeah thats where I got the idea lol, I figured we were doing the same thing in all other aspects anyways...

Sandisk1duo (author)Shinji2008-04-22

cool project though

Sunbanks (author)2008-04-21

To cut it in half you could also run it over with a car :P It splits it in half perfectly. I like this, and I have the righe size LEDs! Yay! Anyway, good job.

marc92 (author)Sunbanks2008-04-21

Hahaha. Did you find that out on purpose?

Sunbanks (author)marc922008-04-21

Haha nope!

fancypenguin845 (author)2008-03-20

if u bounced this @ night someone would think its a ufo how high does it bounce?

marc92 (author)fancypenguin8452008-03-20

I think if you were able to bounce it high enough to be visible to many people the glue would not hold the ball together... Shooting out of an air cannon may work though :)

Naeem Iftikhar (author)2008-02-16

Yes its usefull at many places good job

dkfa (author)2008-02-11

Cool!! But when I saw this I was like...oh does it turn on and off? And affter I read this...I was like....awww...but still a good instructable.

marc92 (author)dkfa2008-02-12

You can use the instructions found here to make the LED only light when bounced, but you may need to use a bigger super ball.

Kaiven (author)2008-02-08

wow looks cool. does it turn on when squeezed, bounced, or always on?

marc92 (author)Kaiven2008-02-08

It is always on.

Kaiven (author)marc922008-02-08

ahh, poopy

marc92 (author)Kaiven2008-02-11

You can use the instructions found here to make the LED only light when bounced, but you may need to use a bigger super ball.

WattSekunde (author)2008-02-10

I have to build one or better two with my kids! Great idea, great fun!
