Acoustic Drone Sensor Hardware Prototype

@AITSoft

Hi, I understand you need one complete acoustic drone-detection sensor built from your finalized BOM, wiring diagram, STL files, and mechanical layout. I can source the listed parts, print all eight PETG mounts, drill and seal the NEMA enclosure, complete the power and I2S wiring, and assemble the unit to match your working prototype. I would check every part against the BOM before purchase, document receipts separately from labor, and test continuity, 3.3V/5V rail stability, Raspberry Pi peripheral detection, LTE connectivity, and the four-mic array alignment. I will also record fit issues, substitutions, and any changes needed because the mechanical model is not yet fabrication-ready CAD. Photos and short videos can be provided throughout the build for your QA records. I have the Electronics, Electrical Engineering, Engineering, and Assembly skills needed for careful prototype work, including soldering, wiring, enclosure modification, and hardware bring-up. I can follow the provided build package closely and discuss the preferred parts reimbursement method before purchasing. Can you share the existing unit’s measured rail voltages, detected microphone details, LTE test result, and beamforming alignment baseline for acceptance testing? Please share the build package and confirm the expected test results for the existing working unit so the second unit can be checked against the same baseline.

Dear Client, The existing working prototype, finalized BOM, wiring diagram and STL files provide a solid foundation for building the second acoustic drone-detection unit. The critical part is reproducing the power, I2S microphone array, LTE, mechanical and acoustic details accurately while validating everything during bring-up and final testing. PCB Must Innovations brings 30+ years of electronics experience across embedded hardware, audio/microphone signal chains, Raspberry Pi, I2S interfaces, mixed-signal wiring, prototyping and hardware validation. Profile: https://www.freelancer.in/u/electronicsdone I can own the complete build from BOM sourcing and PETG fabrication through enclosure preparation, wiring, Raspberry Pi/LTE bring-up, microphone-array installation, beamforming calibration and final testing. The amateur trap is treating a microphone-array prototype as simple wiring while overlooking power stability, I2S configuration, microphone geometry, phase alignment and enclosure-related acoustic effects. I’m happy to offer a free consultation first to review the BOM, wiring, STL files and existing prototype before fabrication starts. One question: should the second unit match the existing prototype 1:1, or are improvements expected in microphone mounting, enclosure sealing or thermal management? Message me with the prototype details and I’ll outline the build, testing and milestone plan. Kind Regards, Prat PCB Must Innovations

@bojans9

Hi, Bojan here, from Serbia. What matters most in building your acoustic drone sensor hardware prototype with 19 line items, 4 Model B and 65 enclosure is a device that behaves the same in the field as on the bench. I'm a senior embedded and electronics engineer with 8+ years of experience working with Raspberry Pi, Electronics and Embedded Systems. With Raspberry Pi, the real challenge is timing, power and real conditions. A common issue: testing only on the bench, so problems appear once the device runs in real conditions. My plan: first, review the schematic, pin map and timing requirements. Then, write the firmware in small modules, each tested on the board. Finally, test on the real hardware under load, power loss and bad signal. The price is in the bid details. I've done firmware work in Raspberry Pi. A few questions to better understand the scope: 1. Should firmware update over the air? That needs a safe bootloader planned from the start. 2. Use the vendor HAL except where timing is tight? I'd recommend it, it's easier to change later. 3. Is this heading to production after the prototype? Then parts and code stay ready for production. I can start right away. Happy to go over the details here in chat and suggest the best approach. Looking forward to hearing from you, Bojan
