this is my first succesful (barely) attempt at electronics and soldering, so most likely if you make this it will be ten times better.

Step 1: materials

for this you will need;

9 volt battery
1k resistor (brown black red)
2 leds
small switch

tools;

soldering iron
pliers
epoxy (i used hot glue)
metal saw
so smarter, I can't make those thing , I just but a <a href="http://sevenpanda.com/solar-power-7-led-flashlight-aluminum-nimh-rechargeable-battery-p-1422.html#.UFwKulFfb9Y" rel="nofollow">Solar Power 7 LED Flashlight</a> Aluminum Ni-MH Rechargeable Battery instead, Well I should learn it carerfully so that I do it myself oneday!

add some aluminium ronuded so the light will be more powerful<br>
Please check www.sunwayproducts.com <br> <br>Sunway has realized it in a complete flashlight in 2006. <br>
I'm making one with a 3x3 led matrix... 9 times brighter, and no resistors required (3volt leds, with 3 series of 3 wired in parallel). <br /> <br /> OOO<br /> OOO<br /> OOO<br /> [[&nbsp; ] &nbsp; ]<br /> <br /> top view!<br /> <br /> I'm using a pcb I got from radioshack for a different project that I&nbsp;didn't use. it's pretty easy to keep one resistor an led and a button in place, but a matrix is a little more difficult.<br />
I finished it (a while ago, actually). I actually decided on a 3x4 matrix, bringing the total to 12 leds. I have some pictures. I hate how bad pictures of flashlights always come out, but believe me, this thing is bright. I use it all the time (last night I used it to light up a rope me and my brother were tying across the creek in our backyard).
i found it worked better witout a resistor. and i redneck soldered(lots of duct tape)
that might blow out the led
correction, that will blow out the led, given time.
and with most leds, that time is about .1 seconds.<br />
Man, do it again, but make photos that we can see, after watching this i want to optomologist but my eyes are Ok, so it look photos are blured, get some friend or somebody more familiar with camera to make it for you,. Good luck
Or you can pay someone $30 for a <a rel="nofollow" href="http://www.9voltlight.com/">finished piece</a>. Woo-hoo!<br/>
Yea, you could, but that's pretty steep.<br/>LED - Radioshaque - $2<br/>Button - Old electronics - Free<br/>Resistor - Radioshaque - $5 for a multipack<br/>Old dead 9V - Free<br/><hr/>Total: &lt; $10<br/>
Making a 9 volt led flashlight? - Priceless
That was a sarcastic "woo-hoo!" It's ridiculous to pay $30 for $1 worth of parts.
Shoulda used a period instead of an exclamation point.
I know, but I like putting this info out. I made one and this is my price list.
thanks,that must be some funny gadgets,for now i didn't succeed to get the stuff in this project and make it out,so i'd like to get one comparing with these <a rel="nofollow" href="http://www.sourcingmap.com/flashlight-c-1137_1335.html">LED flashlight</a>.<br/><br/>thanks the sharing.<br/>
maybe you should lower the resistor.. i used two white LEDs and a 100 ohm resistor.. it works pretty well for me.
I've made something similar to this before, with a high-intensity LED that I soldered to a modified 9V casing with a 3V camera battery inside and a resistor. I used a similar type of switch that I had lying around.
i just wired me another one and it sucks its nott evan bright
Well of course it's not Evan Bright. That would be insane. From the looks at it though, it seems like it would be useful in emergencies.
hey i wired mine differnt and it works but my led like the negetive lead broke off so i have to go to radio shack heres how i wired it (ow i used one led) the postive lead on the led connectedto a half inch in legth of wire then the wire connectedto the resister the resister connected to the positive lesd on the batteiry then the negative lead on the battiery connected to a half of a half inch piece of wire to the swithch then the other length of wire conected to the swithch then conected to the negative termanil (much easier than theres)
pictures in focus would make this instructable better.
too late
Ooooooh...... My first time discecting a nine volt! Intreaguing!
Indeed it is brighter - but I wasn't going to give away my good 'n bright LEDs - those cost money!
i got mine in a pack of ten that cost $2.00
