1. Job Description We are building FyreFite, a real-world recreational tank battle experience based in NSW, Australia. Modified 4x4 vehicles are fitted with tank bodywork and compete using laser tag and a GPS-based firing system. We need an embedded systems developer to build and integrate the hardware sensor package for each vehicle. 2. What You Will Build Each vehicle has a Raspberry Pi running a browser-based radar application. Your job is to make the physical sensors talk to that system reliably. Specifically: - GPS module — tracks the real-time position of each vehicle - Compass module — reads the turret bearing as the gunner rotates it - Tilt/inclinometer sensor — reads the cannon barrel elevation angle - All sensors wired to an Arduino or directly to Raspberry Pi GPIO - Sensor data delivered to the browser app in a defined format You will also integrate two physical outputs triggered by software events: - Compressed air thumper — fires when the vehicle shoots or is hit, shaking the vehicle and making a loud noise - Door open sensor — triggers a safety interlock that disables vehicle movement 3. Responsibilities - Select appropriate sensor modules for GPS, compass, and barrel elevation - Wire all sensors so they can be mounted in separate physical locations on the vehicle (up to 1 metre of cable from the central board) - Write Arduino or RPi firmware to read all sensors and output clean combined data - Agreed output format: GPS:lat,lon|COMPASS:bearing|TILT:angle - Interface with the software developer on data format and timing - Wire and test the compressed air thumper trigger from a software signal - Wire and test the door open sensor - Install and calibrate the sensor package on the prototype vehicle at the NSW site - Document wiring diagrams and setup instructions so units can be replicated for 10+ vehicles 4. Requirements - Hands-on experience with Arduino (Uno, Nano, or similar) - Experience with GPS modules (NEO-6M or similar), compass/magnetometer (HMC5883L or BNO055), and IMU/tilt sensors (MPU6050 or BNO055) - Comfortable with sensor wiring, soldering, and building rugged enclosures for outdoor/vehicle use - Able to communicate sensor data via USB serial or Raspberry Pi GPIO - Able to work alongside a software developer and deliver to a defined interface spec - Based in Australia — on-site work in NSW north coast required at testing phase 5. Nice To Have - Experience mounting electronics in vehicles or outdoor environments - Familiarity with Raspberry Pi GPIO - Experience with inclinometers or tilt sensors in moving environments

Hi, I understand FyreFite needs a reliable sensor package for each 4x4 tank, where GPS position, turret bearing, and cannon tilt are read cleanly and sent to the Raspberry Pi browser radar app in the agreed format: GPS:lat,lon|COMPASS:bearing|TILT:angle. I can help select the right GPS, compass, and tilt modules, wire them for vehicle mounting with up to 1m cable runs, build Arduino/RPi firmware, and test the thumper trigger plus door safety interlock. I will also document wiring, calibration, and setup steps so the system can be repeated across 10+ vehicles. I will keep the build practical for outdoor vehicle use, with stable readings, clear serial/GPIO data, and good communication with your software developer. I can also support on-site prototype testing in NSW when required. Do you already have a preferred Arduino/Raspberry Pi hardware setup for the prototype, or should I suggest the full sensor and control board stack? Best regards,

The honest challenge on FyreFite isn’t reading a GPS or a magnetometer — it’s keeping that data clean and synchronised on a 4x4 that’s bouncing through bush, with a magnetised turret swinging overhead and a pneumatic thumper firing on the same chassis. Magnetic interference, vibration drift, and replication across 10+ vehicles are where most builds fall over. One caveat upfront: I’m not Australia-based, so I can handle the design, firmware, prototype build, and documentation remotely, but the on-site NSW install and calibration would need a local hand or a travel arrangement. Why me? • Designed complex, miniaturized PCBs across STM32, Nordic nRF, ESP32, Raspberry Pi, and Arduino platforms. • Hands-on with NEO-6M GPS, HMC5883L and BNO055 magnetometers, and MPU6050/BNO055 IMUs — including hard-iron and tilt compensation for vehicle-mounted use. • Experienced wiring sensors for rugged outdoor enclosures with proper shielding, strain relief, and 1m+ cable runs. • Comfortable interfacing Arduino to Raspberry Pi via USB serial or GPIO with a clean, defined data format. • Documentation built for replication — wiring diagrams and setup notes so vehicles 2 through 10 go faster than the first. • Responds within 2 minutes during work hours. Happy to jump on a short call to walk through the sensor stack and the replication plan.

Hi, I have extensive experience in Embedded Linux, Raspberry Pi, Arduino-based systems, sensor integration, and hardware/software interfacing. I have worked on embedded products involving real-time data acquisition, communication protocols, and hardware integration in commercial devices. For this project I can assist with selecting appropriate GPS, compass, and tilt sensors, developing the firmware to acquire and combine sensor data, interfacing with the Raspberry Pi application, and implementing the safety interlock and thumper control logic. I can also provide wiring documentation and calibration procedures to support deployment across multiple vehicles. A few technical questions: What update rate is required for the sensor data (5 Hz, 10 Hz, higher)? Is GPS accuracy of standard NEO-class modules sufficient, or is sub-meter accuracy desired? Will the turret rotate continuously (requiring slip rings), or is rotation limited? How is the browser application currently receiving external data (WebSocket, Serial bridge, REST API)? I look forward to discussing the system architecture and deployment requirements. Best regards,

Dear Client, The core challenge in this project is building a reliable real-time sensor integration system where GPS, compass, and tilt data must be accurately captured, synchronized, and transmitted from a moving vehicle to a Raspberry Pi-based browser application under real-world outdoor conditions. I can help turn your concept into a fully working embedded sensor system using Arduino and Raspberry Pi, ensuring stable communication between hardware sensors and your software platform. I have experience with embedded sensor integration, GPS tracking systems, IMU-based orientation sensing, and real-time data communication in mobile and outdoor environments. My approach would be: ✅ select and integrate GPS, magnetometer, and tilt/IMU sensors suitable for rugged vehicle use ✅ develop Arduino or Raspberry Pi to read, fuse, and stream sensor data in real time ✅ integrate digital outputs for compressed air thumper activation and safety interlockk Two things I would confirm first: 1. Should sensor fusion be handled on the Arduino side or directly on the Raspberry Pi for central processing? 2. What is the expected communication method between units—direct serial, CAN-style bus, or network-based streaming? If you message me, I can define a clean hardware architecture and data flow structure to ensure reliable multi-vehicle deployment and easy scaling for your system.

⭐⭐⭐⭐⭐ This is a very interesting real-world embedded systems project because reliability matters just as much as functionality. The biggest technical challenges will be sensor stability in a moving vehicle environment, magnetic interference around the turret assembly, vibration tolerance, and maintaining clean synchronized data between the hardware layer and browser-based radar system. I have strong experience with Arduino/Raspberry Pi integration, vehicle-mounted electronics, GPS/IMU systems, and rugged embedded hardware deployments. I’m comfortable handling both the electronics side and the practical field integration aspects needed for repeatable multi-vehicle installations. I can assist with: • GPS, compass, and inclinometer sensor integration • Arduino or Raspberry Pi firmware development • Stable serial/GPIO communication formatting • Thumper trigger and safety interlock integration • Cable routing and noise-resistant sensor wiring • Outdoor/vehicle-ready mounting considerations • Wiring diagrams and replication documentation for fleet rollout A few questions: Is the turret continuously rotating or limited-angle? Expected GPS update rate and positioning accuracy? Will CAN bus or vehicle power conditioning already exist onboard? This sounds like a fantastic engineering challenge, and I’d love to help bring it into a reliable field-ready system.

Hey there! Projects like this usually run into trouble when sensor data isn’t synchronized properly, readings become unreliable in moving environments, or wiring isn’t rugged enough for real-world use — I’d solve this by designing a stable sensor pipeline with calibrated inputs and durable integration for vehicle conditions. I’ve spent over 10 years working with embedded systems, Arduino, and Raspberry Pi, including sensor integration (GPS, IMU, compass) and real-time data communication, so this kind of system is something I’m very comfortable building end-to-end. For FyreFite, I’d use proven modules (like NEO-6M for GPS and BNO055 for combined compass + tilt to reduce noise and simplify wiring), and build a clean firmware layer (Arduino or Pi) that outputs structured data exactly as required. I’ll ensure stable readings even with vibration and movement, and handle filtering/calibration so your radar app gets clean, usable data. I’ll also integrate the thumper trigger and door safety interlock with proper fail-safe logic. I’m comfortable with wiring, soldering, and building rugged setups for outdoor/vehicle use, and I can document everything clearly so it scales across multiple vehicles. I also understand the importance of on-site calibration for accuracy.

⭐⭐⭐⭐⭐ Senior Embedded Systems Engineer ⭐⭐⭐⭐⭐ Hello there, I am an embedded systems developer specialising in Arduino and Raspberry Pi sensor integration for outdoor and vehicle-mounted applications. A tilt sensor on a moving vehicle is the trickiest calibration challenge in this build — the MPU6050 needs complementary or Kalman filtering to separate barrel elevation from vehicle pitch and roll, otherwise the cannon angle reads incorrectly whenever the 4x4 is on uneven terrain. Built vehicle-mounted sensor packages combining NEO-6M GPS, HMC5883L compass, and MPU6050 IMU, outputting clean combined serial data to a host system at defined intervals. Relay-triggered outputs for physical actuators like your compressed air thumper are straightforward to wire cleanly alongside the sensor data stream. The agreed output format — GPS:lat,lon|COMPASS:bearing|TILT:angle — is clean to implement and easy to extend if the software developer needs additional fields later. Based in Australia and available for the NSW on-site calibration and installation phase. Is the prototype vehicle available for a single calibration visit, or will testing require multiple sessions across different terrain conditions?

I'm confident I can replicate the robust sensor integration you achieved for [mention a similar project if known, otherwise skip/rephrase]. My experience with real-time data acquisition and communication for interactive installations, particularly involving GPS and inertial measurement units, directly aligns with FyreFite's needs for precise vehicle tracking and targeting. My approach will leverage a Raspberry Pi Zero W for each vehicle, communicating with the main system via MQTT over a dedicated local network. I'll integrate a u-blox GPS module for accurate positioning and a BNO055 IMU for a combined accelerometer, gyroscope, and magnetometer, providing heading data. Data will be pre-processed on the Pi to ensure low latency before transmission to the browser-based radar application. I'll implement robust error handling and checksums for reliable data transfer. Could you elaborate on the expected update rate for GPS and compass data? Also, what is the desired resolution for the radar visualization? I'm eager to discuss how my technical expertise can ensure FyreFite's success.
