Proof of Concept Code to Build a Hackable Realistic Civil Defense Siren. To Demonstarate the vulerability in Millions of Real Civil Defense Sirens that work the same across the country

Raspberry Pi Civil Defense Siren is designed to emulate Federal Signal Systems DTMF ONLY for Now.

• SDR (If you want to use radio Activaion)
• Adafruit DRV8871 Brushed DC Motor Driver Breakout (PWM Motor driver) - https://learn.adafruit.com/adafruit-drv8871-brushed-dc-motor-driver-breakout/overview
• Raspberry Pi Model 1, 2, 3, 4
• AirRaid Siren ( or What you want to drive) - https://www.amazon.com/JC-Performance-Powder-Coated-Electric/dp/B01FV5ALI4/ref=sr_1_6?ie=UTF8&qid=1502299372&sr=8-6&keywords=air+raid+siren

• RTL-SDR
• Multimon-ng
• wiringPi 2.52 Thank you @drogon Wiring Pi Will Be missed

Replace Wiring Pi for PWM :(

Decoding Code Needed For:

• Two-tone sequential
• EAS
• POCSAG
• Digital AFSK

This uses a number of open source projects to work properly:

Thank you to all the projects that help make this possable

• RTL_SDR - turns your Realtek RTL2832 based DVB dongle into a SDR receiver.
• MULTIMON-NG - multimon-ng a fork of multimon. It decodes digital transmission modes.
• WiringPi - WiringPi Library for the Raspberry Pi.

This will install RTL-SDR & multimon-ng from apt and install Wiring Pi via deb then build and install AirRaid to /opt/AirRaid

git clone https://github.com/MaxwellDPS/AirRaid.git
cd AirRaid
sudo ./install.sh

$ AirRaid

----------------------------------------------------------
AirRaid PWM RPI Hackable Civil Defense Siren Controler
----------------------------------------------------------
-c, --cli for Command line Control
-d, --daemon To daemonize MUST BE USED with -r OR  -n (Defaults to --network)
-n, --network for UDP Control
-r, --radio to use RTL-SDR for DTMF
-f, --freq Set listen Frequency in HZ Default: 147480000 HZ

Dameon logs to file at /var/log/AirRaid.log

To view live:

$ tail -f /var/log/AirRaid.log

Send the following numbers in ascii to port 21234 via UDP

1 - Growl
2 - ALERT
3 - ATTACK
4 - OFF
99 - EXIT Useful for -d 

1. Install RTL-SDR in RPI
2. Tune Tranceiver to the Listen Frequency DEFAULT: 147.48MHZ
3. Transmit DTMF Tones as set in siren.h

Tones can be changed in src/siren.h after install by editing src/siren.h and running src/build.sh from the AirRaid Directory

Default DTMF:
    TONES:     5
    TIMEOUT:   5 SEC
    OFF:       42061
    GROWL:     42062
    ALERT:     42063
    ATTACK:    42064
