My late 2019 project I decided to take on was a Predator Costume like the one from the 1987 movie Predator with Arnold Schwarzenegger.

Well not a 1/6th scale costume but rather a full sized one.
I can't make the costume perfect movie accurate because 1) I am no where near the height of the original actor who played the predator and 2) picture perfect is time and cost consuming. This costume was put together for under 500 I believe.
This build will be my version of a similar styled P1 Predator with as many bells and whistles as I can put together.
Like all things, we start with the planning. I went to the resources to get a bunch of Pepakura files to start converting for my project. Then I went to Thingiverse to see what they had and grabbed Predator Shoulder Cannon by makerslabcz
After I had all the files, it was time to get to work and make everything printable. It took about a month in spare time to digitally fix everything up and resize it all to my body.

This model was good for pepakura but not for a 3d print. I first ended up fixing the files and printing it out. This will be the shell to house most of electronics and power bank.

I only used half of this model from thingiverse and fitted it with a spot for a flashlight
and a servo
and an outlet for the wires to go out the lower back.

Both halves are held together with 8/32 screws and nuts.

Using this tutorial
, I grabbed an Arduino Mega
, an MPU6050
, battery pack
and wired everything up with 2 Cat 5 connections
(One that goes to the helmet Where the mpu6050 will sit, and one to the left gauntlet for controls and sound)

Continuing with the planning, let's start with the pepakura file and add a hinge in the print so that it can flip up if I need it to. I also made a slot for my Phone below the flip plate.

Let's allow holes for momentary switches and latching switches, cat5 connection and audio out on the flip plate:

Now let's get it printed and loaded up:

I wired it up with an adafruit soundfx board and started wiring everything together. The sound out went to a 3.5mm headphone jack which will plug into an external speaker.

It's actually much cleaner inside now.
