In Tallinn, I’ll assess the CM5-NANO board and HDMI-to-parallel-RGB adapter you’ve designed in KiCad. With hands-on CM5 bring-up and projector interfacing, I recently delivered a tested bench report and a safe, single-supply power plan. Portfolio: https://www.freelancer.com/u/markoa7 - Inspect exact revisions, connectors, and supplies; validate startup behavior with separate rails. - Update KiCad adapter as needed; design the power-distribution harness, provide KiCad files, BOM, Gerbers, and a test procedure. Clarifying question: Can you confirm the start date for the Tallinn bench session and the DC input range you expect for the single-supply design (voltage, current limit, and connector type)? Happy to hop on a quick call to discuss Marko Aleksic

Hello, I can help turn your unvalidated CM5 + DLP projector setup into a measured, stable and repeatable prototype. I have 12+ years of experience in embedded hardware, high-speed PCB design, power electronics and hands-on system bring-up. I will first verify the exact CM5, Waveshare carrier, projector, adapter PCB, connectors, supplies and datasheets before making assumptions. During bring-up, I can measure startup current, rail stability, power sequencing and relevant HDMI/RGB signals to isolate the real failure. I can then design a single-DC-input architecture with protected branches, correct current capacity, filtering, grounding and controlled startup. I can also review and improve your existing KiCad HDMI-to-RGB adapter and design the power-distribution PCB/harness. You will receive editable KiCad files, BOM with exact part numbers, Gerbers, wiring/assembly notes and a complete test procedure. My experience includes Raspberry Pi/embedded systems, multi-amp DC power, high-speed digital interfaces and complex PCB debugging. I suggest quoting the Tallinn assessment separately, followed by the design/prototype milestone based on the measured findings. I am not currently based in Tallinn, so I cannot claim local availability for the initial hands-on session; I can support the project remotely. Regards, Engr Muhammad Usman — Embedded Hardware, High-Speed PCB & Power Electronics Engineer

This is a strong fit, and I’d start with the highest-risk workflow first. For a Electronics/PCB engineer in Tallinn: CM5 + projector and single-input power, the hard part is balancing sensor scanning accuracy, battery life, Bluetooth/SIM fallback, and OTA-ready embedded reliability. My approach would be to validate the sensor matrix and power budget first, then design the acquisition PCB, embedded firmware, connectivity fallback, and OTA/admin controls in staged prototypes. Quick question: What is already available for Electronics/PCB engineer in Tallinn: CM5 + projector and single-input power: a working codebase, designs, data, or only the brief? Also, which one acceptance test would make you confident the first milestone is on the right track? Best, Dr. Syafiq

I am an Embedded Systems and PCB Design Engineer with experience in Altium Designer, Kicad, Easyeda, Protious and custom hardware development. I can design your PCB from schematic to production-ready files, including: • Schematic Design • PCB Layout • Component Selection • Design Rule Check (DRC) • Gerber Generation • BOM Preparation • Manufacturing Support (JLCPCB, PCBWay, etc.) I have experience with ESP32, STM32, sensor interfaces, power supplies, RF modules, Ethernet, and industrial electronics. Please share the project requirements, schematic (if available), board dimensions, and any special requirements. I can start immediately. Looking forward to working with you.

@caodx

Thank you for the detailed description. The project is well aligned with my background in embedded hardware, KiCad PCB design, power-distribution systems, DC/DC converters, STM32- and Raspberry-Pi-based hardware integration, and hardware bring-up/debugging. I can review the existing KiCad adapter design, evaluate the power architecture, design a robust single-supply power-distribution solution, prepare manufacturing files and documentation, and support prototype validation remotely. However, I am not located in Tallinn and therefore cannot provide the requested on-site bench assessment. If you are open to a hybrid approach, a local technician could perform measurements while I support the investigation remotely through schematics, test plans, oscilloscope guidance, and design review. For the later design and prototype stages, I can provide: • KiCad schematic and PCB design updates • Power-distribution PCB and wiring design • BOM with manufacturer part numbers • Assembly and test documentation • Design review of the HDMI-to-parallel-RGB adapter • Remote support during prototype bring-up and validation If on-site presence in Tallinn is a mandatory requirement, you will likely need a local engineer for the first milestone.

As an experienced and multidisciplinary engineer with a speciality integrating mechanical design, electronics, and software - I'm uniquely qualified to handle the complexity of your prototype project. I am proficient in PCB design and have expertise working with power distribution and multiple DC supply systems, which aligns perfectly with your second milestone goals. Building on a solid foundation of knowledge in Raspberry Pi Compute Modules and video/projector interfaces—the very heart of your prototype—I am confident in my ability to perform the critical inspections and bring-up necessary for your first milestone in Tallinn. My track record includes delivering projects from concept to deployment with meticulousness that guarantees no detail is overlooked. I appreciate the significance of consolidated power supply to ensure a safe startup/shutdown, grounding, and prevent voltage drops, this would be a priority on the second milestone. My ability to design unified systems across disciplines is proof that I can handle both the electrical integration work on site and remotely if need be.

Hi, The first priority should be validating the actual CM5/projector hardware on the bench before changing the adapter or assuming the fault is power-related. I’d approach the Tallinn session by checking the exact revisions, supplies, connectors and existing KiCad design, then measuring startup voltages/current and relevant interface signals so the next PCB revision is based on evidence rather than assumptions. For the second milestone, I can help structure the single-DC-input solution around protected power branches, current capacity, voltage drop, grounding, thermal behaviour and startup/shutdown requirements, followed by adapter/power-distribution updates, manufacturing files, BOM, wiring notes and a repeatable test procedure. My background includes C/C++, microcontrollers, electronics-oriented CAD and software/hardware integration. I would keep the initial Tallinn assessment and the subsequent design/prototype phase as separately quoted milestones; the final scope of phase two can be confirmed from the bench findings. For the on-site session, Tallinn availability and scheduling would need to be agreed before the project is awarded. If you send the CM5-NANO-B revision, DLP230NPEVM documentation and current KiCad project first, I can review what should be checked during that session. Thanks, Novak.

@oscarr247

Hi, I understand you need an electronics/embedded engineer for an initial hands-on bench assessment of the CM5 + DLP projector system in Tallinn, followed by power-distribution and PCB development. My background is in embedded systems, firmware, PCB design/layout, and hardware-software integration using C/C++, Embedded C++, Python, and STM32. I’m comfortable working with existing hardware and PCB designs, tracing interfaces, checking electrical behaviour, and debugging issues systematically rather than assuming the fault is in one subsystem. For the first milestone, I can review the board revisions, schematics, datasheets, connectors, supplies, and KiCad design, then work through safe power-up, voltage/current measurements, startup behaviour, signal checks, and hardware integration issues. I can document findings with measurements and clear next steps. For the second stage, I can support the KiCad schematic/PCB updates and power-distribution design, including protected power branches, connectors, current capacity, voltage-drop considerations, grounding, and test documentation. I want to be transparent: my profile does not specifically document Raspberry Pi CM5, TI DLPDLCR230NPEVM, or projector-interface bring-up, nor can I claim Tallinn availability without confirming logistics. If the initial scope and location work, I can review the existing KiCad files and help determine the most practical path forward. Best regards, Oscar Rey.

@eiriks3

Hi, The first priority should be validating the CM5, projector, and HDMI-to-parallel-RGB adapter independently before changing the design, with measured supply behaviour, signal checks, and documented blockers guiding the next revision. For the one-power-cord stage, I would approach it by separating protected DC branches, verifying current headroom and voltage drop, then validating startup/shutdown behaviour before finalizing the PCB or harness. My current profile is stronger in software, system integration, testing, and automation than in hands-on KiCad PCB and high-current power design, so I do not want to overstate experience I have not provided. If you are open to splitting the work, I can support the system-level validation, test planning, documentation, and integration side while a local Tallinn hardware engineer handles the bench and PCB-specific work. Thanks, Eirik.
