Introduction: LED Sinkies

Picture of LED Sinkies

Just like throwies, only waterproof.
This is my first instructable so tell me what you think, or improvements.



First you will need...
1.Tape (Clear)
2.CR2032 3V Lithium Batteries (2 batteries per LED)
3.10mm Non-diffused LEDs.

Step 1: FIRST

First, you need to create a throwie, which can be found here,

The picture is diferent than my finish, cause i couln't get a picture of the one that i was making.

How to make a Throwie...

1.Stack two batteries on top of each other and sandwich them between the legs of the LEDs. Use a few inch long strip of the tape to hold them on completely.

Step 2: WATERPROOFING

Ok now you need Some clear tape(any kind will do, I used Scotch.)

Step 3: Tape It

Now take the throwie and cover it in the tape. Make sure there is no openings.

Step 4: FINISHED!!!

Now your Sinkie is complete. There is no real use for them(at least for me) they are just to light up stuff. Be imaginitave!
(NOTE: LEDs do not work very well under cold weather.)
This is my first instructable so tell me what you think.
(P.S. You might want to tape a rock or another weight to the bottom where the light is so it will sink better.)




Mine was kind of screwed up in the process but you get the idea.

Step 5: Wheeeeeeee!

I like to play with my fish with it, I tie a string on it and dangel it under the water, and they try to get it but it is to big.

Step 6: Extras

You can also not tie a rock to it and let it float on top of the water.


I also put magnets on each side and threw it at my door and it stuck. Tis a metal door.

wats the difference between diffused and non-diffused leds.i know that diffused lights up the color it is,but i mean performance wise.

Hoboman (author)pyro man2008-12-05

Diffusing makes the LED appear dimmer, but gives a wider viewing angle of the light. There really isn't a performance issue there, it only appears dimmer.

thank you!

I came up with somthing similar using a capsule toy machine capsule i called it a depth charge I only have one detail to work out wich is why it's not up yet (im trying to figure out an on off switch)

scienceguy (author)Ward_Nox2008-05-19

you could also use a reed switch. My uncle took a RC sub and put a camera in the front with a battery. He put a reed switch in it. To turn it on he just stuck a small magnet on the outside.

Ward_Nox (author)scienceguy2008-10-15

hmmm i had forgotten about this was looking at my coments list today im gunna have to chart this out and see if i can figure it out

Hoboman (author)scienceguy2008-05-20

That would make a cool I'ble

water proof switches, for boats, they are like $2 at west marine or your local boating store, maby even camper world and sometimes walmart

Hoboman (author)Ward_Nox2007-08-15

cool idea ward_nox.\

Ward_Nox (author)Hoboman2007-08-16

thx once i get the whole thing worked out i'll post it up. Iv'e already thought of a bunch of uses ie. being aable to drink a glowing bubbling potion in a haunted house how awesome would that be):->

Hoboman (author)Ward_Nox2007-08-16

freakin sweet

Radioactive_Legos (author)2008-07-07

Hey, you should coat it in silicone that comes in a tube or hot glue. That way you could be sure it is waterproof. Just make sure the LED itself is not covered so you can recover it after the battery dies.

Thats a pretty good idea, but im not exactly sure how i might recover the led, you would have to put silicone on the led's cathode and anode to attach it to the battery so it will stick. Right? Thus rendering the led unrecoverable. :)

Sort of...
But you can cut up the silicone and scrape it off the leads. Once I receive my LED throwie kit from the Let it Glow contest, I'll try it and maybe make an Instructable on it ;)

video tape the fish trying to eat it I want to see

Huntman00 (author)2008-02-17

tie the throwie to a fishing pole and put it in the tank (do not put a hook on it)

Hoboman (author)Huntman002008-02-17

lol

Huntman00 (author)Hoboman2008-02-18

i am seroise

Mocabai (author)2007-09-19

I've got and idea =). theres an instructable on a "ice jewel" or something named like that where you make a water balloon then half freeze it so the center is still water. you could add some of these as well as some floaties and would look awesome =). (sorry for the sucky grammar)

Hoboman (author)Mocabai2007-09-20

thad bee freakin awesom dude.

Hoboman (author)2007-08-10

firesnake, you beat me to the idea, :')

Hoboman (author)2007-08-06

thanks footballgirl004 glad press n' seal bags would work great!

footballgirl004 (author)2007-08-02

instead of tape why not try like a ziplock bag or glad press and seal
