Introduction: Easy LED Flashlight

Hello,
Welcome to my Easy LED Flashlight

What do I need?
(1) LED Light--White or Blue. Make sure that on the box it says 3 Volts or more.
(1) AA Battery Holder
(1) 9 Volt Battery Clip
(2) AA Batteries
(1) Altoids Case, Chewing Gum
(1) Push button switch with two leads on the bottom.

Purpose- The purpose of this project is to make an easy, affordable, AA battery LED Flashlight. The light is good for little nooks and crannys, and also for finding your wa around the house at night.

Step 1: Drilling Hole for Pushbutton and LED

Ok, so this is an easy step.

First, with a Sharpie marker, draw a dot where you want to put your Push button and your LED. On my Altoids Flashlight, I put my light on the front, and the PB (Pushbutton) switch on the top.

Take a drill, and drill the holes to size. Make one hole, check it, and then make it bigger if it is needed.

I used a Dremel tool to drill the hole, but you can also easily use a drill.

It cannot be that hard.

Step 2: Lets Get Ready Solder!!!!

Ok, so if you do not have a soldering iron right now, I would suggest you purchase one because many DIY projects that use LED's use the help of solder.

The LED from Radioshack that I used has a max voltage of 3 Volts, and I am using 2 1.5v batteries to that works out very well. So no need for a resistor.

Lets Get Started!

In the schematic/cartoon below, there are several things you must identify.

The smaller lead of the LED is the NEGATIVE lead.
The black wire from the battery snap is also NEGATIVE.
The red wire from the battery snap is POSITIVE.
The wire going from the second lead of the PB switch is hookup wire.

So,
1) The negative lead of the battery snap gets connected to one of the leads of the pushbutton switch.
2)Get a piece of hookup wire it to the SMALLER lead of the LED and the ohter lead of the pushbutton switch.

MAKE SURE THERE IS NO SOLDER BETWEEN THE TWO PUSHBUTTON SWITCHES!

3)After you do this get the RED, or positive lead of the battery snap. This will connect to the LONGER lead of the LED.

I do not need to show you what to solder together because the picture below is all you need. Whereever a wire is touching a lead of a component, you have to solder it.


Next Step: Fitting it into a tin.

Step 3: Fitting It Into a Tin.

So right now you should have tested the light to see if it works. It should work. Make sure you test it before you put it in a tin.

1) Drill a hole for the LED. I did mine in the front and I attached the switch to the top.
2) Once you have the hole drilled, place the LED into the hole so the light sticks out

You don't have a resistor so the 4.5v LED just blew from giving it 9v.

I want to make this project so badly, but i don't have a soldering iron...

radioshack sells a soldering kit for about $10

You don't necessarily need a soldering iron, you can try twisting the wire around the leads.

why a 9V battery when you can use a 3 v battery with a protective resistor?

to find the proper resistor the formula is this one :
9V - (voltage of your led) / (led intensity in A)

thanks!

One suggestion is add a Resistor so you don't blow the LED just place one between the positive on the battery and LED.

Here's a proper schematic with protective resistor, feel free to add it to your instructable.

You should add a resistor.

i dont get it

pyro man (author)2008-12-11

ok,you lost me. the nine volt clip is suppossed to clip onto the AA battery holder?!?!!?!?!?!

author
fallenspirit123 (author)pyro man2008-12-11

yes

author
pyro man (author)fallenspirit1232008-12-11

well ''excuse'' me but iv never seen a battery holder like that

author
fallenspirit123 (author)pyro man2008-12-12

all I did was answer your question! man its true! You get jealous way to easy

author
pyro man (author)fallenspirit1232008-12-12

jealous? how i that jealous? and i was joking anyway. you care '''WAY''' too much

author
fallenspirit123 (author)pyro man2008-12-13

Nope...not really I just answered your Q and you went off like I was yelling at you

author
pyro man (author)fallenspirit1232008-12-13

w/e have you seen a battery holder like that?

author
fallenspirit123 (author)pyro man2008-12-13

radioshack sells them

author
pyro man (author)fallenspirit1232008-12-13

figures

author
fallenspirit123 (author)pyro man2008-12-15

haha! lol well...yo!

author
pyro man (author)fallenspirit1232008-12-12

hold on! wtf do you mean its true?

author
fallenspirit123 (author)pyro man2008-12-13

Its true that you get jealous easy!

author
Coonie (author)2007-12-08

great Instructable! but its kind of harder than it should be to figure out. try searching "altoids led flashlight" and click the first one. its a little more easy to figure out and it was my first ever led project and it was sooooo fun!

what is the next best place to get all this rather than ripoff shack locally in boise idaho

author
finnster (author)2008-05-07

where do u by buttons /switches

author
Brennn10 (author)finnster2008-05-07

Sadly, I had to buy them from Radioshack. But any online store will also have these supplies.

olvegrn (author)2007-11-04

People love mine! I have made 3 so far. one is just a single blue LED with resistors of course, and the other ones are double LED ambers with resistors of course. THANKS FOR THE FUN!

author

AWESOME!!! Glad to hear it!

i am 17 i don't have a credit card and Radioshack is a block away i don't have to wait for them to be shipped

author

Ohh, I see. You should get a Wachovia Visa Buxx card. It is for teenagers, and your parents can upload your allowance onto the card. You can use it anywhere. I love mine.

author

i don't have an allowance but hopefully i am getting a job at radioshack soon i go for my interview on monday

author

Good Luck man, if you are hired, you will get discounts on everything!

author

it would make my wallet happier since i am broke and it would make my parents happier because i would have finally got a job so i can pay for gas for the truck i will be driving.

author
theatre_tech_guru (author)2007-09-22

Radioshack is all we have in canyon country so leave it alone

author

Why don't you order from the internet? That was what I was referring to. I have yet to find a store near my home that sells LED at bulk.

Radioshack is a joke compared to other electronic component dealers. I bet somewhere else, I could find 10 of those for that price.

author
theatre_tech_guru (author)2007-09-21

they sell LED'S with resistors.

author

With resistors already soldered on? Hmm, I never seen those. Could you post a link?

author
HIGHVOLTAGE-Z (author)2007-07-10

would it work if the pushbutton has two PRONGS instead of two leads please answer

author
Brennn10 (author)HIGHVOLTAGE-Z2007-07-13

Are they the same thing?

author
HIGHVOLTAGE-Z (author)2007-07-09

hey gobob29 how did you make yours? please reply

author
AlbinoBlackSheep (author)2007-06-18

Thanks so much!!! I made one for my Mom as a birthday present. I really liked gobob29's (I think. The link was broken, so I assume it was gobob29's) idea to have 2 LED's and 2 switches. Mine has blue and white. She'll really like it for navigating the house at night.

How did you collaborate with yourself!?

author
Brennn10 (author)Ian012007-02-12

Do you wanna know "how" i did it or "why" I did it?

author
Ian01 (author)Brennn102007-02-26

both.

author
Brennn10 (author)Ian012007-02-27

Well when you go to collaberate at the end of your instructable, you can collaberate with groups and users. Click users, and type your name in. I guess its as easy as that.
