It was more than a year since I had a Carnifex model but I had no time to assemble and paint it. But someday I saw a Mawloc/Trygon/Prime made with magnets and decided to make something similar with Carnifex. I choosed the type I wanted to make and someday when I was holding the head of the beast I suddenly thought: "there's plenty of space in his head, why not place there a diode?" But logic almost erased that thought. If I place a diode there then there will be only 1 head. I didn't want that. Same time I wanted to go further than just magnets or just a diode. But how can I make this? How can I mix both of them. I wanted more heads and glowing same time.

And finally dawned on me. Magnets are metals too and they could be used as conductors. It will be a very simple and effective circuit. So that almost erased thought was very tenacious.

You can see the result above and creation process below.
The first frustration came when I began to process some parts. They were not matching each other sometimes with 3mm (0,12 inch) holes and terrible mould lines. Totally frustrated. GW quality sucked.
But closer to the topic.

All it began from head. I needed to make glowing eyes but eye-pits were elliptical and diodes were deep inside the skull. I didn't want to leave just a hole there.


I remembered about optic fiber but there was nothing handy around. So I decided to use hot glue gun. It was simple and very effective. Right choice!
Used this oneto make this

Result


Next step was making the circuit itself, how can I hide it inside?
The solution - "He has big leg, it can take all inside"


Similar with the tail


Next step - body and magnets

It was simple as a brick. 2 magnets inside each head, 2 magnets in opposing place on body. Sounds easy, doesn't it? Well it is not.
The idea was to solder wires to magnets and make a circuit, but rare earth magnets are working great only at room temperature. If their temperature grows above 80 degrees Celsius they become completely irreversibly demagnetized
Maybe make some wires contacting without soldering? But reliability of such connection was very small.
What should I do then?

The solution was found again and it was as simple as the first one. Even if they will be demagnetized they still will be metals with magnetic possibility by another magnet.


The main circuit problems were solved, now it's tome to put some magnets in other parts.




Put them on heads (with soldered diode inside the skull)

In crushing claws too

Inside carapace

Even in tail

Actually they were everywhere now.


The last was the painting, but this is for another story...
