How to Make a Terminator CPU Brain Chip From T2.

I was given a glass dome as a present so i wanted to make a little something to go inside it.

i started thinking about small props i could make and i came up with the brain chip from terminator 2.

So here is my instructables on how to make a T2 brain chip.

i did a little google for terminator brain chip and found a couple of images that gave it scale.

Materials:

-2mm perspex
-1mm brass tube\bar
-spray paint
-solvent glue
-glass dome (optional)

Tools:
-laser cutter
-lighter or candle

I drew up some plans in illustrator by looking at the research pictures to get scale and details.
the width of the chip i worked out to be roughly 25mm and the length is roughly 65mm.

scaling some pictures to this size showed that the total thickness was around 6mm thick.

Then cut the parts parts out of 2mm thick plastic on a laser cutter.

i glued the correct squares into their correct places and glues them down.

i know that the clear version looks a little shoddy but when its painted up it looks a lot better.

I made two different versions of the brain chip, the damaged chip that they steal from Cyberdyne, and one complete clean version.

i sprayed the chips with a plastic primer.

i made two little port discs, i tried to make them look like the port where the chips are pulled from inside the terminators head.

i painted them with plastic primer as well.

I gave the two chip bases a coat of metallic silver\grey and the two different chips a coat of gold/brass paint. 

once all the paint has dried i mixed up two different colours of rusty red\brown and painted the darker of the two onto the damaged chip and the lighter, more red, colour onto the complete chip.

Now its time to make the damaged chip look .. well damaged.

i took a lighter with a large flame and ran it over the 'broken' end of the chip to give it the singed burnt melted look.

**be careful doing this, it is dangerous do not set the chip on fire, if this does happen use water to put it out do not touch the melted plastic as it is very hot and will burn. Also wear a respirator or do this in a well ventilated area.**


i also used some black and brown to make it look dirty and rust and just old.

I took one of the two base discs and painted it to be rusty and dirty. this one will hold the damaged chip.
The clean disc will hole the clean chip.

i took a length of 1mm brass tube and bent it so that it would sit in the hole in the disk and just support the back of the chip so it can be removed and studied.

i glued the tube underneath one side of the disc.

so now both disks have a little bar that will hold the chip.

once all the glue and paint had dried i had two little terminator brain chips. 

These are purely decorative and are to go on my prop shelf along with my arc reactors and portal gun.

you could drill a little hole in one corner and use it as a key chain or if you know about usb sticks i guess you could make a usb flash drive from it.

casting it and making little reproductions with space inside would be a way of doing that.

if i had a 3d printer i could make these to hold anything (as long as its small enough. )

thank you for reading my instructable. any questions or suggestions leave them in the comments section.
