Mechanical Design Jobs

I want to bring a small, ESP32-powered toy drone from concept to first lift-off. The goal is purely recreational: a fun flyer that can be controlled from a smartphone rather than a conventional RC transmitter. Core functionality must include reliable auto-stabilization so even a beginner can keep the craft level. Here’s what I already have in mind: • Flight controller: ESP32 (your choice of dev-kit or custom PCB) • Sensors: a compact 6-axis IMU such as MPU6050/ICM-20689 for attitude data • Motors & ESCs: typical micro-quadcopter class, but I’m open to your sizing suggestions • Firmware environment: Arduino IDE or ESP-IDF—whichever you can deliver faster and maintainably • Mobile control: a lightweight Android/iOS app communicating via...

I have a completed audiophile phono-preamp in ExpressPCB+ — schematic and two-layer board — that I now need recreated in Fusion 360 Electronics. The circuit holds 33 unique parts (about 120 total) and follows a simple structure: one power-supply section repeated six times and two identical audio channels. Because of this repetition, copy-and-paste inside Fusion should accelerate the job. All manufacturer part numbers are ready to drop straight into the new library, so you will not have to hunt for footprints or symbols. Trace widths and clearances can remain at Fusion’s defaults; no additional design-rule tuning is required. We will also keep the layer count exactly the same as in the ExpressPCB+ file. Mechanical constraints are critical: • Overall board outline m...

What I’m looking for 1. Accurate CAD models and fabrication drawings based on real-world rail dimensions (preferably gathered by you or sourced from verified databases). 2. An assembly guide that shows the clamping process step by step. 3. Suggestions on fasteners, surface tr...

My new-construction home in California (just over 4,000 sq ft) needs a complete HVAC design package. The concept I want to pursue is a dual heat-pump arrangement paired with a passive cooling strategy; beyond that, I’m relying on solid load calculations to dictate exact equipment selection, whether that ends up being Carrier, Trane, Lennox, or another equivalent line.

I have derived the governing equations for a rotating, pre-twisted blade treated as a thin shallow shell and now need a full modal vibration study. The formulation already includes the complete mass matrix, the gyroscopic matrix, and separate stiffness contributions for the structural shell, centrifugal stiffening, rotational softening, and an elastic root represented by spring constants. Thickness varies along the span, so any solution must respect the taper, the twist, and the elastic root support while the tip remains free. Your task is to compute the natural frequencies and mode shapes across a practical range of rotational speeds, capturing the combined influence of centrifugal force, Coriolis coupling, and rotational stiffening. Please work directly from the matrix form I provide, o...

I need a complete finite-element model of a Warren through truss bridge built in ANSYS (Workbench Mechanical or APDL). The task covers geometry creation, material assignment, boundary conditions and, most importantly, a dynamic study that captures wind and traffic effects. For wind, please implement a realistic fluctuating pressure profile; for traffic, model moving axle loads that travel the bridge length with appropriate speed and spacing. Time-history or transient structural analysis is preferred so that true stress-strain and displacement histories can be extracted. I have only a broad idea of where sensors should sit—mid-span, panel points near supports, and a few along the top chord—so I will rely on your structural-health-monitoring experience to pin down the exact n...

I already have an ESP32-C3 prototype of AutoSmear running reliably on a hand-wired board, but now it is time to turn that lab-bench tangle into a production-ready PCB. Compact layout is my top priority: the board must fit inside the existing enclosure while leaving room for future shielding and airflow. Just as important, the A4988 motor driver needs to be integrated cleanly so the stepper that moves the blood-film spreader glides without vibration or jerks. What I will hand over to you • Tested firmware ( ESP32-C3) • Current schematic, wiring diagram and BOM • Mechanical constraints for board outline and mounting points What I need back • Updated schematic reflecting any refinements you suggest • Space-efficient multilayer PCB layout with proper ground...

I need a mechanical design engineer who can turn my concept for an industrial hydraulic tilting table into a complete, fabrication-ready package. The table must safely handle heavy loads over 2 000 kg while tilting through 0–45 °, and its movement has to be managed by a fully automatic hydraulic control system with position feedback, safety interlocks, and a clean operator interface. The schedule is tight: I’d like to kick off immediately, see a first concept layout within a few days, and iterate rapidly to final approval. Throughout, I expect solid adherence to ISO/ASME standards, careful attention to weldment rigidity, and documented strength calculations that demonstrate an adequate factor of safety at every tilt angle. Deliverables • 3D CAD model (SolidWorks or I...

My prototype runs on two independent 360-degree servos that each turn a separate gear train to drive plungers. A 1.68" display and a small vibration motor round out the user interface. Functionally it works, but the mechanics feel rudimentary and the control electronics are still at a breadboard stage. Mechanical scope • Keep the existing architecture but focus on Optimization of current gear system – smoother meshing, tighter tolerances and balanced loads so each plunger actuates cleanly without stalling or backlash. • Verify torque requirements against the present servos; if calculations show a shortfall we can discuss alternate motors, yet the preference is to retain the dual-servo approach. Electrical scope • Redesign the control PCB with Increased dur...

I need an accurate set of “as-is” engineered drawings for an existing mechanical structural framework. The physical assembly is already built; what I’m missing is formal documentation that captures its current state in a clear, fabrication-ready format. The scope centers on mechanical drawings only. Every major component, connection, and interface within the framework should be represented so a fabricator or maintenance crew could rebuild or service the structure without guesswork. I’m looking for detailed assembly-level information rather than high-level outlines. You’re free to model in AutoCAD, SolidWorks, Inventor or a comparable package, as long as the final output is delivered in both native and PDF/DWG for easy sharing. However, only 2D technical draw...

It’s only a guide — we’re flexible and open to improvements or refinements you recommend. We need a designer who can model the body + chassis and create basic servo-driven linkages for doors, bonnet, and boot. Vehicle dimensions, the ideal engine mockup type, and the gearbox mockup will all be finalized together during the design process. What We Need: BODY • Exterior 3D...

Slurry Pump Seal Design I need a complete mechanical-seal solution for a low-pressure (≤10 bar) slurry pump that moves highly abrasive media. I have settled on a pusher-type seal, so the job is to engineer the full seal arrangement—gland plate, sleeve, flush plan if needed, and all mating hardware—tailored for abrasive duty and sized to my pump’s envelope. Once the design is established, I also want a procurement roadmap that relies on Indian-made components only. This means identifying suitable face materials, secondary seals, springs, and hardware that are manufactured domestically, along with vendor contact details and indicative lead times. Deliverables • 3-D model & 2-D manufacturing drawings (STEP / DWG or SolidWorks) • Material and tolerance spe...
