Homewbrew Soldering Iron

IN THIS INSCRUTABLE I WILL BE SHOWING YOU HOW TO MAKE A HOME BREW SOLDERING IRON
Things you will need

(1)-12-18volt Cordless Drill Battery 
(2)- A Old Plug From A Cut Extension Cord Or Something Similar
(3)- 2 Small  Alligator Clips
(4)-2 Cheap Bic Pens Or 2 (NON) Conductive Things To Use s Handles 
(5)- Electrical Tape
(6)- Graphite Mechanical Pencil Led (PREFERRED) Or Just Some Led Taken From A Old Pencil
(7)-Solder 
(8)- Sun Glasses( The Led Glows Very Bright)
(9)- Well ventilated Area

Step 1: Checking The Polarity Of The Battery

On Most Battery's There Is A + And - To Let The Consumer Know Which Is Which 
In My Case There Was Not , So If You Have The Same Issue As I Did,   Checking The Polarity Is Very Simple. Grab 2 Lengths Of Copper Wire (solid)  Then Grab  A Glass Of Salt Water.
Place One End Of The Wire In The Salt Water Nd The Other ON the Lead Of The Battery.

The Wire With The Most Bubbles Is The - Kool Knowledge-> (You Just Built A Hydrogen Generator )  Now Mark The Battery According To The - +

this does work very well, even with a single 4V lithium ion cell, although I feel a warning should be made that large gauge wire should be used as smaller gauge wire gets very hot during use.

A multi-meter works to test polarity as well.

Not seeing how this fits in with the USB contest at all. also, this seems incredibly dangerous...

[Adam Manick]

He used a computer with USB to post this instructable. :)

I agree. Drills and such have been designed to accept these batteries and keep them from overloading. This has no limits and, I would imagine, could overload the battery and cause a meltdown or explosion. Just a suggestion.

[goofyboi2008]

yes I'm sure if not positive that could happen that's why I mention that it shouldn't be used for a long period of time, when the 2 ends are not touching it dosent heat up.

[goofyboi2008]

USB no it dosent you are right. and if the directions are followed it is not hazerdous. I soldered over 60 connections on my laptop with no problems.

[EZtrollin]

would a 15 volt wall plug make any difference? i don't exactly have a drill battery just lying around.

[goofyboi2008]

I strongly dont recommend using a wall plug because the cord doses heat up, it doesn't need to be a 18 volt battery it can be 12, also a car battery charger is another preferred power source

you seem to lack a lot of description of how the handles and soldering equipment go together. I also got confused because I was wondering how a light emitting diode led fit in here. Took me a while to see you were referring to pencil lead. Good idea though.

[goofyboi2008]

I was just going to comment that I never once said anything about a LED but as I was scolling to comment I noticed I was missing the A hehe

[Jodex]

USB contest, eh..?

[goofyboi2008]

to tell the truth I didn't relize the USB contest was a literal translation, I just thought it was a contest lol

[zipzapper859]

yeah i don't get that there is not USB port anywhere

[Jodex]

And your reply was a bit intricate.
