Introduction: DIY GLOWING PENCIL LEAD

Hai readers iam going to show how to make the pencil lead to glow like a light. During the process the lead can reach upto 300°¢ so be carefull while doing this.


Step 1: •°Components Required•°

* Pencil Lead
* Testube
* Meatel cap X 2
* Big Needle X 2
* ball point pen nib to hold lead at the edges
* 15 V DC supply

Step 2: °•Use 0.7 Lead•°

I used 0.7 pencli lead and 15V Dc power supply from li-ion battery

Step 3: °•Setting Up the Lead Inside the Tube°•

First take the Testube and break the bottom of the test tube. Now take metal cap and make hole in the centre of the cap. Now take the cloth stretching needle to make holder. To hold pencil lead you need to make holder. I used the ball point pen nib to hold the lead. Solder the ball point pen nib at the end of the needle by tieing it with thin copper wire. Now you can easily fix the lead inside the test tube

Step 4: •°POWERING UP°•

I powered this lead by using the 12v 7A li-ion battery the lead started glow by emiting the white coloured gas

Why would'n I just use a bulb?

What is the advantage of using a pencil instead of bulb?

Is it juist the AC problem?

i wanna 2 do something new...soo i choosed pencil lead...ya

Won't this short circuit the battery and consequently cause it to over heat?
