Protect timeline 2 working days max Project max 100cdn have a working RF receiver board with stable firmware, but the companion transmitter board is unusable because the only Gerber and BOM I was sent are corrupted. The transmitter’s firmware binary is intact, so the new hardware must accept that code without modification and still communicate flawlessly with the existing receiver over our RF data-transmission link. What I can supply: • The corrupted Gerber and BOM as rough references • High-resolution photos of the original populated transmitter board • The receiver board’s schematic and dimensions • The compiled transmitter firmware (HEX) Your task is to recreate the complete transmitter design from the ground up—clean schematic, PCB layout,...

I need a complete board designed around an audio-grade DSP that will sit at the heart of a home audio system. The board must include on-board equalizer control as its core feature and run from a stable AC-adapter input—no battery support required. Here is what I expect: • Schematic capture and component selection for the DSP, audio codecs, power-supply stage (AC-to-DC conversion and regulation), and all supporting passives • A space-efficient, low-noise PCB layout ready for fabrication, delivered as Gerber, drill, and assembly drawings • Firmware or register-map settings that enable the equalizer section, along with clear documentation on how to tweak bands and presets • A complete, production-ready BOM with manufacturer part numbers and sourcing notes &...

I need an experienced electronics specialist to replicate a monitoring sensor device demonstrated in a YouTube video. The device primarily monitors proximity and motion data. The device uses an ld2450 and seeed xiao2350 and a 2.42in l2c display. The video has links to the source code and wiring diagram but the diagram and video leave out core info to do it myself (such as wiring in the switch etc...) Video: Key Requirements: - Replicate the device accurately as shown in the video - Ensure it monitors proximity/motion data (e.g., distance, speed) - Use quality components for durability and reliability Ideal Skills and Experience: - Proficiency in electronics and sensor technology - Experience with video-based project replication - Attention to detail and strong problem-solving skills ...

The latest spin of my automotive-grade sensor board works, but a few components have shown reliability issues in the field. I need a hardware engineer to review the current BOM, swap out the failing parts, route the new board, and verify the board is sound again. Targeted components 1. Connectors. 2. Diodes. 3. Oscillators. Details will follow. Acceptance A revised project archive (schematic, PCB, updated BOM) and a confirmation that the new connectors, diodes, and oscillators perform within spec. The freelancer should be open to conduct voice and/or video calls.

I’m working with a Diode Laser Board and I need a custom receiver that can plug into that setup, track the machine’s positioning in real time, and instantly flag any faults it detects. The idea is to have continuous monitoring so I can see where the laser head is at any moment and receive automatic alerts if something drifts out of spec or a component misbehaves. Ideally, the receiver will take positioning data straight from the board, process it with minimal latency, and expose a simple interface—serial, USB, or another protocol you recommend—so the data can be displayed live on a host PC or microcontroller dashboard. Reliability is critical, so built-in error detection should cover signal integrity, unexpected motion, and any other obvious fault conditions you id...

Request for a Custom Pre-Configured CAN/CAN-FD Gateway for EV BMS Development and Testing I would like to request a quotation for a complete, standalone CAN/CAN-FD gateway system. I am looking for a device that can be connected between the vehicle and the OBD connector using an OBD interposer, and that can operate independently without a PC using pre-loaded configurations. The main purpose of the system is development and testing of battery/BMS CAN communication in electric vehicles. The vehicles I would like to support are: * Tesla Model 3 * Tesla Model Y * Kia e-Niro * Hyundai Kona Electric * Volkswagen ID.3 * Volkswagen ID.4 I will provide the exact model years for each vehicle at the beginning of the project. Required functionality * At least 2 independent CAN/CAN-FD channels *...

I'm seeking an ultrasound engineer that is knowledgeable in regard to immersion transducers for biomedical purposes. I have currently have quotes for components but need to ensure compatibility between systems.

Project Title MATLAB/Simulink Tutor Needed for PMDC Motor, Fan Load and PID Control Project Project Description I am looking for an experienced MATLAB/Simulink tutor to provide technical guidance for a university electromechanical systems project involving a permanent-magnet DC (PMDC) motor, an industrial fan load, and PID speed control. This is a tutoring and technical-support project. I must personally complete and submit the assessed work. The freelancer should explain the modelling process, help identify errors, review my independently prepared model and results, and provide constructive feedback. The freelancer must not write or submit the final assessed report on my behalf. Topics Covered The project includes: Developing a PMDC motor model in Simulink from its electrical and mechanic...

I want a LabVIEW-based curve tracer that mirrors the behaviour of the Digilent WaveForms instrument but runs entirely inside LabVIEW while talking to my Analog Discovery 2. The program must sweep a user-defined voltage across a device, sample the resulting current and voltage, and plot the I-V curve in real time. Primary test focus is on resistors, yet it should also cope with simple LED measurements so the code isn’t locked to a single device type. Please make the sweep limits and step size configurable so I can adapt quickly to different resistor values or LED forward voltages. The interface needs to feel as quick and informative as WaveForms, with one extra twist: I need reliable data-export options (CSV at a minimum) straight from the GUI so I can toss results into Excel or...
