I have a complete schematic ready and now need it translated into a production-ready multi-layer PCB. The board will carry a mix of high-speed signals and power lines, so careful layer stacking, impedance control, and good grounding practices are critical. You’ll start from my annotated schematic (PDF + native CAD format) and component datasheets. I’ll also share form-factor constraints and the connector placement I must keep. From there, I expect: • Clean, rule-checked PCB layout in the CAD tool you normally use (Altium, KiCad, or Eagle are all fine). • Gerber/ODB++ files, drill files, and pick-and-place data prepared for fabrication. • Source CAD files so I can make future edits. • A concise design report summarising layer stack, controlled-imp...

I need complete Gerber files for a multi-layer printed circuit board that will be built on six layers.

I need a concise, technically sound guide that shows forecourt operators in Europe exactly how to keep pulser tampering devices out of their fuel dispensers. The focus is on prevention rather than post-event detection, so the material should walk through proven countermeasures, hardware safeguards, software lock-outs, on-site inspection routines, and staff training practices that collectively shut down the main attack vectors. Scope • Explain how pulser manipulation is commonly attempted in European dispenser models (Gilbarco, Tokheim, Wayne, etc.) only as context for the preventive steps. • Lay out step-by-step prevention methods with references to real-world roll-outs in EU service stations where possible. • Highlight regulation or certification requirements that bols...

We are looking to purchase an existing, completed substation design package for a 345 kV / 34.5 kV substation with a 1½ breaker scheme on the 345 kV side.

Deliverables • Editable design files in KiCad • Gerbers, drill files, pick-an...

I need a control-systems specialist to build a Model Predictive Controller for a wind turbine that I have already represented as a Linear Parameter-Varying (LPV) model in MATLAB/Simulink. The controller must juggle three objectives at once—maximising electrical power output, keeping mechanical stress to a minimum, and sharpening pitch-angle accuracy—while remaining robust to real-world disturbances such as wind-speed fluctuations, grid faults, and the occasional mechanical component hiccup. The core work happens in MATLAB/Simulink: setting up the prediction model, formulating the multi-objective cost function, and implementing hard or soft constraints that reflect turbine limits and grid-code requirements. I will provide the LPV model and any necessary operating data; you desi...

I have a 140 × 54 ft heavy-timber framed home already engineered; the full structural package is in hand and ready to share, including floorplan and elevations for every space. I need them tied seamlessly to a construction-ready Mechanical, Electrical, and Plumbing design. I am primarily building with SIP's and ICF's, so there will be a strict limitation on the number of penetrations between the interior and exterior envelope.

All work should conform to current state of Washington, Whatcom County, and City of Blaine codes. Deliverables I’ll supply the structural drawings in PDF format. You will return a coo...

I want an HID Omnikey 3021 smart-card reader—converted so it connects through a standard USB-C port instead of USB-A, while still providing full-speed data communication and bus power. I only need the cable/connector side removed and replaced with a USB-C connector so the device enumerates and draws power over USB-C just as reliably as it does over USB-A. There should be no cable, just a USB-C connector so that the device is as small as possible. Here is what will make the job a success: • The finished reader plugs into any standard USB-C host and both powers up and transfers smart-card data without errors. • All USB-C wiring follows the spec’s pin-out and current-handling guidelines. • You supply clear documentation (schematic or wiring map, parts used and...

All numerical data and complex tables must be converted into vibrant, modern charts that highlight key trends and statistical markers. The presentation must follow a logical sequence from the technical problem to the methodology, results, and a sophisticated critical evaluation of t...

I have an ageing GE iFIX 4.0 SCADA node running on Windows XP that can’t be networked or put online. All I need is the tag database for a set of specific points; however, I’m not yet sure how many tags there are and my list may reach you in whatever format I can pull together—Excel, a text file, maybe even a scanned page. Your task is to help me get those tags out of the locked-down machine and into a clean, shareable file (CSV or XML is fine). Because remote access is impossible, I’ll either follow detailed step-by-step instructions you provide or run any lightweight utility or script you supply (VBScript, PowerShell 1.0–compatible, or a Workspace VBA macro) directly on the PC. No changes to the live project—just a safe export from the iFIX database ...

We have a electronic siren system which have some electronic components. There is a metal enclosure in which all the components are placed. The problem is that, the current system is temporary like a jugaad. We want to get the modular system designed so the goal is: 1. make every component plug and play 2. wirings and cables hidden inside and secure 3. make connections plug and play 4. Thermal dissipation so system cools down internally as there is no exit in the enclosure 5. make system compact and robust for coastal and extreme conditions. 6. Heat sinks and other ways we can make it temperature controlled. Let me also attach a basic requirements document also (AI generated according to our requirements) You are an expert so you can also suggest the implementation things.

Greetings! I have multiple projects, ranging from homes and apartment blocks through to office towers, retail spaces, warehouses, and light-industrial plants, and I need complete HVAC designs turned around quickly. Every building requires the full suite—reliable heating and cooling, balanced ventilation, and active air-quality control—so your plans must integrate those three elements seamlessly rather than treating them as add-ons. Because these systems will be submitted for LOCAL PERMITS, every drawing, calculation, and specification must meet the applicable local building codes. If you also work to ASHRAE or other industry benchmarks, that is a welcome plus, but code compliance is the hard requirement. Deliverables WE expect for each building: • Precise load calculatio...

I’m developing a compact, aluminium-clad SMD PCB that will live directly on mains, so every detail must be right first time. The board sits on 1 mm aluminium with 25 µm copper, accepts 220-260 VAC and has to deliver a rock-solid 144 VDC at 300-350 mA. Power-factor must stay high thanks to a hybrid DOB topology, while the protection network must survive 6 kV surges and automatically cut in on both high- and low-voltage events. Everything must be RoHS-compliant. Because the board ultimately feeds a power-supply module, thermals and creepage/clearance are just as critical as the electrical design. I’m looking for a clean, production-ready package that lets me hand Gerbers straight to my fabricator and have parts placed with confidence. Deliverables • Complete schema...

I need a complete engineering solution for an ultra-low-frequency electromagnetic transmitter that operates at roughly 22 Hz and fits inside an inline pipeline PIG. Once the PIG is in service, the beacon’s field must be strong enough to be detected up 3–5 m above the pipe, even when the signal has to pass through steel wall, backfill, soil, and asphalt or reinforced concrete. All operations take place underground and fully enclosed by steel, so coil geometry, core selection, drive strategy, and noise rejection are critical. Scope of Work: • Design a low-frequency (~15–30 Hz, target 22 Hz) EM transmitter • Optimize signal strength for underground detection • Develop efficient antenna/coil design suitable for pipeline use • Design low-power circuitry fo...
