Nice idea !!
We need:

2 sewing needles one second medical
Power supply from the mobile phone (I'll use on Iphone 10W USB Power Adapter . ( apple )

Model no: A1357 0010ADU00 Input 100-240 V 0.45A 50-60Hz Output: 5.1 V 2.1A )

Threadheat shrink tubing
Super glue
Soldering Iron
Barbecue skewers

Step 2: A Long-awaited Video About How to Make a Mini Pyrography Tool at Home.

Step 3: It's Quite Simple to Make a Small Pyrography Tool and It Can Be Made at Home With Just Two Needles and Old Unnecessary Power Supply From Mobile Phone.

Step 4: Since Now at Technology Lessons You Will Have the Most Extraordinary Pyrography Tool.

<p>Can someone tell me where to get the Needles? Ive looked saw some, but i wanna make sure I get the right ones.</p>
<p>I found them at animal farm supply places if that helps</p>
<p>I have a question, could I use heat shrink tube to hold needles instead of thread and glue?</p>
<h3>no need for a resistor</h3><p>i have read in a few comments that a current limiting should be added, but most if not all powersupplies have a current limitation internal. for this to work there should be more than 2A of current, given that an apple power charger is 5V the resistor should dissipate more than 10W, most resistors are rated 1/4W, also that kind of resistor would be bulky and will become warm, instead of the tip becoming hot making the tool useless</p>
<p>FIY: ADD A CURRENT LIMITING RESISTOR<br><br>If not, it's possible for this to short out the power supply, which may cause fuse to blow up, and might cause a fire.... so for your own sake, add a current limiting resistor. You can calculate the value you need using Ohm's Law</p>
<p>Should the resistor go between the needles and the battery BEFORE the positive connects to the needles, or AFTER the needles? Also, how would you calculate the resistance needed?</p>
You can connect it either way, it work both way. But personally I prefer to connect it before the needle. You can calculate the value of the resistor using Ohm's law
yes that's what I'm talking about :-) :-) :-) .
with out a current limiting resistor between the needles and the supply, the needles will act like a short which will pull as much current from the supply as possable. this is not good! in the case of the apple charger being used as the supply, it is very likely it has current limiting built in. but for the people who will try to build this with a different supply it is good to include.

<p>Kind of. A cool tool anyway! :D</p>
<p>Hey... great idea. I tried building this myself but the entire syringe <br>needle got so hot that it burnt the wooden pencil and the threads almost<br> instantly. Is there any way to control the temperature and limit the <br>heat to the tip? Perhaps I should use a voltage divider or something to <br>limit the current.... right?</p>

<p>Im not sure what i did wrong but this didnt work, i could be the old charger i used?</p>
<p>You need to renew your domain . looks like it has expired 11 days ago. :/<br>Just so you know. <br>Oбнови Домен . ;) </p>
I really like this! Could you use more or less than 10 watts, would that affect how hot it gets? What would a limiting resistor look like in the circuit?
<p>More watts is always better</p>
Very neat idea! How do the needles get so hot but not melt / burn the thread, glue and heat-shrink?
<p>Espectacular idea y muy sencilla de realizar ademas de lo econ&oacute;mico de la propuesta, gracias por compartir.</p>
<p>I really love this tool.. Thank you so much for posting such an interesting and useful instructable.</p>
what sort of temp does this get up to
<p>this is awesome</p>
very good idea but?? I think you are making a short circuit Right ?? :-)
<p>That is to cool. I am more outdoors than electric but may try that. I used to wood burn as a little guy.</p>
way cool!!! I mean hot!!! love this idea as I am a photographer myself!!! I never thought of making my own tool, tools for woodburning!!! Again way cool(hot)!!!!? I'll check you out on YouTube as well!!! cool beans, man!!!?
<p>Very nice and easy. I think I'll try this one. I give it an A+.</p>
<p>I guess, normal soldering gun can act same like pyrography tool as well, did you try is it work with soldering gun?</p><p>I have some concern about this mini tool which is the power consumption, is it consume within charger specification,10 Watt? If more than that then might not good for your charger in long term.</p>
<p>I use a soldering gun for woodburning myself. It's not a terribly precise tool, but it gets the job done for the most part.</p>
<p>be careful with superglue, if accidently heated, if produces acid like gas. Had that experience once back in the past.</p>
<p>Good one and easy to make.</p><p>Does the needle last long without get burned?</p><p>Can it be used for soldering?</p>
<p>What type of power supply will this require?</p>
<p>Power supply from the mobile phone (I'll use on Iphone 10W USB Power Adapter . ( apple )</p><p>Model no: A1357 0010ADU00 Input 100-240 V 0.45A 50-60Hz Output: 5.1 V 2.1A )</p>
5v 1A ???
<p>10W USB Power Adapter . ( apple )<br>Model no: A1357 0010ADU00 <br>Input 100-240 V 0.45A 50-60Hz<br>Output: 5.1 V 2.1A</p>
