Hello, this time i am here with a modification of my previous battery powered soldering iron . This one is very very short sized this uses only 4 AA batteries and does the work a a good soldering iron 1 Hope you will like it it very compact like a thick bold marker!
And it can work like an 35 watt soldering iron and it's very safe to use also because it  takes 10 seconds max to get  very very hot and 5 secs to cools down . The actual thing is you simply need to press a button and in 10 secs it ready to use.

Step 1: Stuff You Need!

All you need is some common house hold stuff! and if you don't have it you can easily buy one from any general store !

1. Paper , pencil ,  A pair of scissors , transparent tape and some sketch pens !

2. Rechargeable battery * 4

3. Some hard metal strips , pliers , wires and soldering stuff!

Step 2: Procedure

Now you are going to the final procedure  


  • This procedure is quiet tricky first connect four Rechargeable AA 1.5 volts batteries in series .

  • Tape them as i have done or you can do it your own way it's your choice what you prefer.

  • Now connect a push button to the negative terminal and connect a hard core wire to the other side of the push button the stick it with some glue.

  • Now connect a power jack holder or "i don't know what it called" to the batteries for charging them. You can see how i did it.

  • Take a metal strip fold it like a tight lead holder and rub the other side so you can solder it and the solder it like i had done.

  • Now put the graphite pencil lead and insert in in the metal strip.

  • Now solder the metal strip with a high wattage soldering iron.

  • Wrap the hard core wire connected to the negative terminal such that it's quiet far from the other side.

  • Here you go! Just press the push-button and wait for 10 secs and it will start smoking this smoking will not happen after 10 to 20 times use.



Step 3: Casing and Finishing

Once you've made the whole setup now it time for casing . The casing is also important cause it prevents the heat of the main body to catch you fingers . And it looks pretty well too. I used a simple cardboard and painted it with water color so it looks pretty !

Step 4: Author Tips

These are simple instructions and description of this soldering iron!


  • This soldering iron get's hot in only 10 secs ! It's the mAximum time taken by this iron to get hot in fact if the battery's power is at 60% it get's hot in only 4 to 5 secs .
  • The battery should be charged regularly after a 5 hrs use and the minimum charge duration should be 5hours at least.
  • Don't use the soldering iron for a long time duration max is 30 secs after 30secs release the push button for minimum 4 seconds the continue for 30 secs again.
  • And don't get confused on what's the tip the graphite lead itself is the tip of it.
  • The graphite rod needs to be replaced monthly!
  • Now that's all Enjoy


Can I use a Sony rechargeable 9v battery?
<p>check the battery's current rating!</p>
<p>can you explain what i did wrong i mean like i followed every single step</p>
<p>As i've stated more than 100 times my friend , you need a good battery , as far as I believe you're using a cheap battery , that is used in tv remotes , DONT USE THEM , instead use 4 dura cells or any high current batteries like those. </p>
<p>I did everything as you have done.But I made a small change.Instead of 4 1.5 VOLTS CELL, I used a <em><strong>9 VOLT BATTERY</strong></em>. <strong><em>EVEN THEN IT DIDN'T WORK!!! COULD YOU PLEASE EXPLAIN???</em></strong></p>
<p>it didnt work for me either</p>
<p>The 9 vots battery is not able to serve rwequired amount of current (AMPS) i guess you are using a HW blue colored 9 volt battery for 12 rupees but as i have explain MR . WANTED you can't use this you have to use a good battery like 6vots sunac battery with high current capacity.</p>
<p>this didnt work for me bro</p>
Dont you think sooner or later the batteries are going to burst. I have read the caution notices and heating the battery is so very dead. Even though the switch is turned off after 30 secs the heat precipitated on +ve terminal is quite risky. The idea is clever things are compact but thats the only thing am not very fond of.
As far as i think you can make the metal strip wide and long i think this will act quiet like a heatsink and prevent the batteries from bursting.
<p>I understand that making the metal strip wider and longer would keep it cool, but you also will need to put down is that doing this will also slow down the amount of voltage and current.</p>
<p>No it will not lower the current or voltage!</p>
<p>sorry for arguing but i used 2 EW 9vt battery which is each RS 20.</p>
it is superb <br>and I know it wud work bcoz i have tried to make a light bulb using the lead as the filament &amp; gas came out when i connected it to a 6vt battery <br>DOUBTS <br>can i use a 9vt battery <br>can i use a mechanical pencil refill for the tip (5mm)
The tip will be very thin and break several times and you can use a 9v battery not problem but with max capacity!
This is a really bad idea. Using dissimilar cells in conjunction means that you're pushing current through dead cells, and probably fully draining ni-cad cells, which severely limits life.
Okay you are right but they are not very dissimilar cause i have used same type AA and same company battery but but still there is some difference and you're right too but i don't have similar batteries so i have used quiet Dissimilar one you can use similar ones! No matter.
I was talking about the difference between double and triple A batteries. The internal resistance and capacity of the two will be very different even from the same company.
Can you show a video of it in action? I really need something like this :) Its handy and simple to make :D
Vishal please refer to this link:http://www.youtube.com/watch?v=pZytTnZkEFY
Guys please please vote for me! i the poll will be available in one or two days.
sorry but it's not very clear, but still very nicely done!
