Everyone knows that graphite is installed in the pencil, which transmits current well. This property can be used to create an electric pencil, thanks to which it is possible to easily engrave on knives and other conductive surfaces.
We recommend starting production by watching the author’s video
So we need:
- an ordinary pencil;
- a piece of wire;
- a piece of wire with a crocodile at the end;
- a piece of wire with a plug;
- a bulb with a cartridge;
- latex gloves;
- any surface on which we will apply the drawing.
The author draws a picture on a stainless knife, but as we said above, any conductive material can be used. Let's turn to turning an ordinary pencil into an electric one. To do this, at the end of the pencil you need to connect the wire to graphite. To do this, remove the eraser and drill it in the center with a thin drill.
Then we pass the wire through the drilled eraser, having previously exposed the tip of the wire.
It is also necessary to sharpen the pencil a little in the area where the wire is connected, so that the latter touches better with graphite.
Putting the pencil back by installing the eraser with the wire in its place.
The main work is done. Now you can take care of the correct connection of the electric pencil. The wire that comes from the pencil is connected to one terminal of the bulb.
We connect one wire coming from the plug to the second output of the bulb.
A wire on which there is a crocodile is connected to the second wire from the plug.
The pencil works as follows. To apply the picture, you need to connect the crocodile to the item that will be engraved, be sure to wear rubber gloves and connect the plug to the power source. In order not to spoil the surface, you can apply the future drawing with an ordinary pencil.
