Electrical Engineering Jobs

I need a concise Arduino Uno sketch that drives my Nema 34 stepper through its existing driver in a continuous loop with the following timing: • From home, turn 60° clockwise and hold that position for one second. • Return to the home position and pause one second. • Turn 60° anticlockwise, pause one second, then repeat the entire sequence indefinitely. Please base the calculations on a typical 200-step Nema 34 (1.8° per step) unless I can later change a constant for different micro-stepping settings. No sensors or limit switches are required; it is pure open-loop control. Alongside the .ino file, include a clear wiring diagram that shows the connections between the Arduino Uno, my stepper driver, power supply, and any needed resistors or opto-isolators so...

i need a .vex file produced for a transmitter we sell to iBwave software users

My circuit is already captured as a clear schematic diagram; it contains just four to five surface-mount parts that form a simple signal-processing stage. All I need now is a production-ready, single-sided PCB layout turned around quickly. Key points you should know: • Single copper layer only – no vias to the reverse side. • Components are 100 % SMD; please place them so hand-soldering remains possible. • Board function is signal processing, so keep any sensitive nets short and well-routed. Deliverables I expect: • Complete Gerber / drill set ready for fabrication • Source layout file in your chosen tool (KiCad, Altium, Easy-EDA, etc.) • Simple placement PDF so I can check part orientation If you can start right away and hand back a cle...

Engineer must be based in England and be able to travel (Lincolnshire area) I need a complete wiring schematic for an existing electrical control panel that currently runs without any formal documentation.

This project involves updates to signal processing, and possible EMI compliance updates on an existing board. The PCB has already passed Part 15 emissions, but there is reason to think it may not pass CE. The successful candidate will possess, at minimum, a BSEE and extensive experience with Altium. The specifics are adding a dual analog switch to low noise signals for a musical instrument. Some existing components may need to be moved. We are specifying US based freelancers only.

PROJECT SUMMARY:Perform a comprehensive active Radio Frequency (RF) and Wireless Local Area Network (WLAN) site survey across six (6) dormitory buildings totaling approximately 308,943 sq. ft. at Tyndall AFB, FL. The objective is to evaluate coverage, capacity, signal propagation, and interference to support long-term wireless infrastructure planning. Frequency Bands: Measure and evaluate coverage across 2.4 GHz, 5 GHz, and 6 GHz (Wi-Fi 6E/7) bands. Methodology: Utilize an AP-on-a-Stick (APaaS) setup to simulate real-world access point propagation, signal attenuation through facility walls/doors, and optimal AP mounting Coverage: Conduct continuous active and passive survey walkthroughs across designated corridors, common spaces, and representative living quarters within all 6 dorm...

I sell home solar systems and need a dependable specialist to turn each new enquiry into a polished, numbers-driven proposal. We work with off-the-shelf software; the exact platform is still being finalised, so proven experience in Aurora Solar, PVsyst, SolarDesignTool or a similar package is ideal. For every lead I will provide: • The customer’s historic energy-use profile (kWh by month) • Roof measurements, pitch and orientation from site photos or satellite data With that, you will size the PV array, run a production model, calculate financial savings and payback, then export a branded PDF ready to send. Accuracy in shading assessment, component selection and utility-rate modelling is essential, and I aim for a 24-hour turnaround once you receive the data. D...

Looking for someone that is an expert with ATS. Need some changes done both mechanical and electrical. Need to show past work on this field

I have a novel reluctance-motor geometry sketched out and need a quick, standalone feasibility check focused strictly on the magnetic field distribution. Your task is to set up the model in COMSOL Multiphysics, excite it with the parameters I will share (current, air-gap length, rotor/stator materials), and generate clear field-visualization plots of the magnetic flux density (B-field). Scope • Build or import the supplied 2D axisymmetric or 3D CAD—whichever you believe captures the physics without overcomplicating the run time. • Assign material properties, boundary conditions, and appropriate meshing so saturation and fringing are captured realistically. • Sweep at least two operating points (no-load and expected peak current) to see how the flux paths evolv...

I need a custom mixed-signal circuit engineered from the ground up to drive an optical wireless communication link. The design must cleanly blend an accurate analog front-end—handling photodiode receive and LED/VCSEL drive stages—with the required digital processing blocks for modulation, clock recovery, and protocol framing. My priority is signal integrity across the entire chain: low-noise transimpedance amplification, precise ADC/DAC selection, and robust high-speed PCB layout that minimises jitter and EMI. Component choices should be commercially available and cost-effective for a small production run. Because the target is an optical wireless channel rather than Bluetooth, Wi-Fi, or Zigbee, you are free to choose or recommend the most suitable modulation scheme (e.g., ...

I am putting together the electrical backbone for a new home and need a complete design for both the AC Distribution Board (ACDB) and the DC Distribution Board (DCDB). The system must serve typical residential loads safely and efficiently, and I want surge protection built in from the outset. You are free to select the most suitable brands and models for breakers, SPDs, busbars, enclosures, meters, and any other components; I’m looking for unbiased, performance-driven recommendations rather than being locked into a single manufacturer. Local code compliance and best-practice wiring conventions are non-negotiable. If you normally work in AutoCAD, Revit, E-Plan, or similar CAD/electrical design software, please keep using your preferred tool—just be sure the final files are ea...

An electrical schematic now exists only as a digital image and must be recreated as a clean, fully editable drawing. The task is strictly a redraw—no changes to the circuit itself—so every symbol, wire number, reference designator, and note has to match the original image exactly. Use any mainstream electrical-CAD platform you are comfortable with (AutoCAD Electrical, EPLAN, OrCAD, etc.); just be sure the drawing complies with standard drafting conventions and layer discipline so it can be maintained later. Deliverables • Native CAD file of the finished schematic • A print-ready PDF generated from that file Before hand-off I will spot-check key nets, component labels, and title-block data against the source image to confirm accuracy and completeness.

I need a dependable freelance technician I can call whenever a printer stops behaving in my clients’ stores around Dubai. The bulk of the work is mechanical repairs—think carriage alignment, stubborn paper-feed rollers, worn gears or a tired print head—on Epson LQ/LX dot-matrix units and a variety of thermal receipt printers used at the point of sale. All work happens on-site. Once I log a ticket, you meet the customer, diagnose the fault, carry out the fix, and leave the machine printing a clean self-test. If a part must be taken away for deeper work, you handle pickup and return, but most issues should be closed during the visit. What makes you perfect for this job • Proven, hands-on experience with dot-matrix and thermal receipt printers. • Comfortable ar...
