Step 3: Hack your Cold Heat soldering iron (3 - Modify)

With your case modified and your components removed, it is time to make modifications and integrate the parts. First, scuff the inside wall (opening side, not hinged side) of the tin where the batteries will be installed. I chose the right side. Place the battery terminal designed for both positive and negative on this wall, heat it up, and solder the battery terminals to the wall. Since the tin is essentially a large heat sink, it will take a lot of heat to get the solder to stick to the wall as well as the terminal. Again, refer to the photos for dimensions. With this in place, cover the entire interior of the case with tape. The tin is conductive, and these batteries have a lot of energy in them. If you do not tape the walls, you could complete the circuit, drain the battery, and create a potential fire hazard. Do not be scared of this, just respect the power of the batteries and be safe.

Next remove the positive terminal (no spring) from the LED, and connect the red wire directly to the LED. At this time, you can shorten all of the cables as much as you want for packing convenience. It is not necessary, but it is recommended.

Add a short length of wire to the LED terminal with the red wire to attach to the just removed positive terminal. You will also need to solder a wire from this same junction to the center tab on the CHSI tip holder (thick yellow wire in image).

Replace the center terminal wire from the switch with a longer wire, and attach this to the negative battery terminal (with spring). Cover all exposed metal with electrical tape, tape the white LED (near the tip) to the tip so the light shines through the hole in the case for the tip, and cover the circuit board with tape. Attach the red LED to the tape covered circuit board, and stuff everything into the case as shown below. You may need to tape or epoxy the switch in place depending on how your installation worked out. It is possible to use just tape and friction from the wires, but use adhesive if you are looking for a more permanent fix.

You are now done with the Cold Heat Soldering Iron hack.
You added HST, but nothing to shrink it. Wouldn't it need a lighter?
hi this is cool man <br><br>i like it man.<br><br>thanx
i think this is a great instructable!!!
great ible. but im gonna have to make an iron in a can with some old school iron because i could never get my cold heat one hot enough to melt any solder :(
Your sentence, "Hack your alligator clip wire leads (or crocodile clip leads for those of you in FL)" makes no sense. Florida has alligators, not crocodiles.
actually, in south Florida, we have both. The everglades is the only place in the world where alligators and crocodiles live in the same place.
technicalities my friend! ;)))
Uhm, I hope you can appreciate the value of paying the utmost attention to &quot;technicalities&quot; when dealing with basically anything related to the purpose of this site. I'm just saying, taking a <em>laissez faire</em> approach to technicalities is how one gets a 120V surprise.<br/>
You know what REALLY "makes no sense?" Your statement that "Florida has alligators, not crocodiles." Yes, Florida has alligators TOO, but it also happens to be the only place in the U.S. that HAS CROCODILES. The Florida crocodiles are estimated to be some 400-500 and are on the rise. I find your whole "You shouldn't say crocodile clips instead of alligator clips YER JOKE ISN TEH FUNNAY" to not only be asinine, and pointless, but you're also "technically" wrong. Despite his statement being an obvious joke that you, for whatever reason, decided to get your panties in a twist over, his statement was also "technically" correct. You didn't do your homework and decided to jump on him for his correct and tongue-in-cheek joke. I won't even get into the fact that you then go on to suggest that by his joke (allegedly) being incorrect that this could equate to someone getting electrocuted. Are you for real?
Ah, I stand corrected... Their numbers are now in the thousands, and they're being considered for removal from the endangered species list according to <a rel="nofollow" href="http://news.nationalgeographic.com/news/2003/08/0821_030821_tvcrocs.html">National Geographic</a> and <a rel="nofollow" href="http://www.npr.org/templates/story/story.php?storyId=9718547">the NPR</a>. <br/>
HAHAAHAHAHAHA.........excellent risponce dude
So much for "i dont have bad language" eh?
OK maybe u have right but any other site than here, go to electo-tech.com and say this and then i will agree with u 150% but here no. Focus on the job, the spirit and the gnessis of this idea coming project. And don't spoil the spirit of any member here. They deserve the best, and from us looki an advice and some claps, to aplause their job, else u remember me the guy who was looking the tree and was forgot all the f.... forest. Iam not bitter in my feelings or havi bad language but that's the spirit of www.istructables.com.....elso go to the MIt forums...and make yourself feel better;)))
I suppose I got this wrong. I think I had begun typing one thing, edited it, and forgot to run the coherence checker.
they have a coherence checker?
apparently they do <a rel="nofollow" href="http://www.lcc.uma.es/~duran/ChC/">http://www.lcc.uma.es/~duran/ChC/</a> <br/>
yup, and someone wrote gullible at the top of this ible'
no; i was just wondering cause it would be nice if they did, in fact, have one.
oh, lolz
meh , there both big , long and dnagerous , this reminds me of something...
i think he was being politically correct so as not to insult the alligators. you wasted your time arguing semantics, and i just wasted time replying to you.
Lol you had me laughing at "Hack your Strippers" no offense.
awesome intro
I really hated the Coldheat... The brittle tips kept breaking, and I couldn't do micro soldering easily...
II find the cold heat unit a dissapointing purchase myself. I had one of these <a rel="nofollow" href="http://www.gigaweb.com/products/view/3585/60-pro-charge-cordless-rechargeable-soldering-iron.html">http://www.gigaweb.com/products/view/3585/60-pro-charge-cordless-rechargeable-soldering-iron.html</a> when I was doing a lot repairs in the field. I loved it but, it looks like inflation occurred in the mean time, and they where a boring gray color back then.<br/>
i got a WELLER butane soldering iron for 15 bucks at home depot and i love
I have been eyeballing those. I like the Wahl because it was quick to come up to operating temp.Also quich to cool down so so worries about melting any plastic in came in contact with after putting it in the tool box.
so how good does that cold heat soldering iron work does it do as much as a regular soldering iron
This note is in reference to the two posts below should they still be there when this is read: The Cold Heat Soldering Iron and the wire strippers used in this instructable are less than ideal. They are finicky, brittle, the wrong tool, and underpowered. This said, they were used in the making of this instructable, and are only intended to be used in a pinch, where small size and convenience are more valuable than user friendly operation and frustration free work. I do not recommend either of these tools for your everyday toolbox.
yeah yeah i know, no diss intended. <br/><br/>just letting the folks know of a useful purpose of the tool intended and how to use it properly or an alternative with broader uses<br/><br/>*peace* bro :-D<br/>
No diss taken, I agree with you.
just a point on those wire strippers. they suck pretty bad for normal wire, but they're designed for removing the outer layer of insulation from coax or multicore wire such as cat5. the plastic bracket applys just enough force to cut most of the way through the outer layer so it can be easily removed with a bend and a yank. personally id be looking for somthing like some fold-out scissors from a sewing kit. that covers you for all manner of stripping, cutting and gouging, all sure to be useful in an emergency. look around for a good set tho, there are some very bad examples that will only make you cuss and or hurt your fingers. a better pair wont be much easier to use (teensy tools in man-size hands never are), but at least will work.
Fold out scissors would be a great improvement in the future. I will have to look around. I used the wire strippers to do all of the wire stripping seen above, and had a tough (but successful) time with them.
Iculus: Great 'ible, and I'm sorry I didn't manage to see it previously. (Glad you're in the finalists stage, and good luck in the judging!) I think I may have to actually do exactly this with my cold heat gun. Currently, my "soldering kit" consists of a shoe box with a bunch of crap in it. The other day I needed to do a quick and simple solder job to test a hobby engine and ended up having to pull everything out and make a wreck of my table. This is just brilliant.
Such an awesome idea, so cool!
With all these awesome pocket-sized entrys, I'm running out of pockets to put them all in! :D Nice Instructable.
*cough*cargopants*cough* ;O) ~adamvan2000
I love this idea, its great. I am always taking a bag of computer parts or electronics with me where ever I go along with the tools to work on them now i will be able to solder them while on the go. The only thing i see in this that i don't agree with is wrapping the shrink tube in electrical tape, that tape tends to leave a real sticky residue. Great ins
The piece of heat shrink tubing wrapped with tape is designed to be sacrificial and is only used as a smaller diameter tape core. The remaining pieces of tubing should remain un-taped, to prevent exactly what you are describing. Sticky tubing would be terrible.
Stop using electric tape and try masking tape no residue. unless you had plans on using the black tape.
you could just as easily use a toothpick, or straw, or what have you...that piece of heat shrink used as the e-tape core is no longer meant to be used as heat shrink, although in an emergency you still could. he used it because he had some left over from cutting the rest of the heat shrink down to size. the only function it serves is to make a smaller core for the e-tape included in the kit.
I too have tried to use a ColdHeat iron. You have to keep both sides of the split tip touch metal or wire for the iron to heat up and that is not always easy to do. As soon as the tip loses contact the iron is cold. The small battery irons work much better and I think mine only takes 15 seconds to heat up. But you can't put it in your pocket just after using it. However, I never felt the need to carry a soldering iron in my pocket and I am smart enough not to touch the tip of a hot iron.
And after you've fixed the wire the hard way (the quick way would be having some wago clips and a wire stripper), you pack everything, anxious to get back to your game and put shove the hot soldering iron in your pocket!
It's a dangerous situation, this is why this uses the cold heat iron, so it cools off before you can even get it in your pocket.
First off: this is &pound;&#8364;@&yen;ing amazing!<br/><sup>_</sup><br/>Second: I'm just wearing underwear, what pocket will I fit it in...<br/><br/>...oh, god......no...*&#8226;*<br/>
make sure its not on , oh and customs might get a bit funny if you have a soldering iron up uz a**
