### To the ATF, It is structurally impossible for this design to be used with a real weapon and is not our goal. I am a law-abiding citizen.

### To Lockheed Martin, call me...

## Documentation is NOT complete. In progress

# TF2Sentry

This is the final piece of a project with [Maiikiru](https://github.com/Maiikiru) and Bradon

to create a fully functioning level one sentry from TF2 using an AIRSOFT gun.



Inbetween classes and work each of us have put countless hours into creating a cool project.



The work can be broken up into 3 repos.

- [Maiikiru's CV Repo](https://github.com/Maiikiru/TF2SentrySource) for the brain and the logic

- [Bradon's CAD Repo](https://github.com/ConvexBurrito5/TF2SentryCAD) for the physical CAD/STL files

- [Current Repo](https://github.com/ConvexBurrito5/TF2SentryEE) for circuitry and build instructions.



This repo is my work (Steven Naliwajka/ConvexBurrito5), [GitHub](https://github.com/ConvexBurrito5), [LinkedIn](https://www.linkedin.com/in/steven-naliwajka-69564929a/).



### Two options for targeting: 

1) Maiikiru has gone through and created a Computer vision (CV) repo that automatically detects and targets people: [Maiikiru's CV Repo](https://github.com/Maiikiru/TF2SentrySource)

2) I have also gone and created a remote control, [a slightly modified wrangler](https://www.youtube.com/watch?v=LYPzGNSfVRk)



To jump straight into building, see the Documentation folder.

## Review of my learned Skills

- At a high level, what we are trying to accomplish is simple however, as always, implementation is not as easy. I have learned lots:

  - Communication!

    - I2C Communication, learned how to implement and write code to utilize it in python.

    - Radio, utilizing 2.4Ghz wireless transceiver modules to talk from the turret to the wrangler

  - Power!

    - The turret and wrangler run off batteries.

    - 7.6v, 12v, 9.2v was all required. Got to use Buck DC voltage regulators.

    - Load calculation to make sure at least 5 hours of battery life.

  - Circuitry!

    - Circuitry to be able to plug in the turret without removing the battery. Same for Wrangler.

    - Performed proper wire size calculations; by working out max amps through each.

  - Coding!

    - Python - My first real project in python. I'm typically a java slob, so it was a little bit of a culture shock. But I'm glad I got to learn.

    - Arduino(C++) - Got to continue to hone my skills.

    - Git - I was dragged into the 21st century by Maiikiru. I'm proficient at Git now.

  - 3D Design!

    - Solidworks - I am competent at solidworks now.

  - Improved my 3D printing troubleshooting skills... and gotten a sizeable print farm out of it (2 decked out Ender 3s)

  - Working with Motors/Servos with control from both I2C and PWM.



With that out of the way, lets look into what we have completed.

## Features of the project

- Detection and tracking of a person, See [Maiikiru's CV Repo](https://github.com/Maiikiru/TF2SentrySource)

- We have provided [Maiikiru's CV Repo](https://github.com/Maiikiru/TF2SentrySource) with standard API interfaces so it easy to implement multiple hardware solutions. So far:

  - Raspberry Pi 5 (Please do not use a pi4, we tried to make it work, the performance is not good) , See 'instructionFT232H.md'

  - Standard laptop using [Adafruit's FT232H Breakout](https://www.adafruit.com/product/2264), See 'instructionRaspberryPi4.md'

- There are 4 interfaces implemented in each solution

  - FiringController

    - Handles the firing by pulling logic high on a switch to bridge the motor on the airsoft gun.

  - MotorController

    - Handles all motion. Basic set of methods to move your servos.

    - Idle motion, pans slowly looking for people.

  - PeripheralController

    - Handles the leds

  - SoundController

    - Handles all the sound, runs off of the devices default speaker.

- If a switch on the wrangler is turned on, automatic movement from [Maiikiru's CV Repo](https://github.com/Maiikiru/TF2SentrySource) will be disabled and overruled.

  - Input will be solely from the joystick and the firing button on the Wrangler.



## How can you build one?

Good news! Through many sleepless nights of documentation I have

compiled instructions to build your own TF2 Turret. You can begin by
