I need an experienced solar PV design engineer who can jump straight into a small-scale residential project and turn around professional drawings and calculations without delay. The site offers less than 1,000 sq. ft. of usable roof space, and the homeowner’s primary objective is to cut monthly electricity bills, so every watt and panel placement must be optimised for cost-to-benefit. You’ll receive roof photographs, basic structural information, and recent utility bills as soon as we start. From there I expect a full design package that can be handed to the local installer and utility for approval. Please rely on industry-standard tools you’re comfortable with—PVsyst, HelioScope, AutoCAD, SketchUp, or similar—to validate shading, estimate annual energy yield...

My goal is to take several upcoming Mechanical, Electrical and Plumbing scopes from the first sketch straight through commissioning and hand-over. I therefore need seasoned, end-to-end guidance that covers every decision point—concept design, detailed calculations, drawings, equipment selection, code compliance, procurement, installation sequencing, testing, and final close-out. The assignment spans all three disciplines, so I will rely on you to align ductwork, power distribution and piping layouts into one fully coordinated package, flag clashes early, and help optimise energy, water and maintenance costs. Because this is an A-to-Z brief, I expect practical advice on site logistics, contractor coordination, scheduling and quality checks in addition to the core engineering work. T...

The original schematics and firmware sources for my existing motherboard are no longer available, yet I still need to keep the product alive and solve a series of recurring hardware failures. The immediate objective is to reverse-engineer the board in detail so I have a complete, accurate picture of how every power rail, I/O interface, and embedded controller is wired and programmed. Once that knowledge is captured, I want a refreshed design that removes today’s failure points and is ready for a short production run. Work starts with non-destructive teardown, high-resolution imaging, net tracing, and firmware dumping via JTAG/SWD or any other proven technique. From there the task moves into schematic recreation (Altium Designer or KiCad preferred), BOM generation with current compon...

I’m putting together an all-terrain rover that pairs a Raspberry Pi 5 with an Arduino. The Arduino will sit close to the hardware, polling and driving everything from temperature-humidity probes and distance sensors to an IMU (pitch/yaw/roll, altitude, compass), ESC-PWM motor controllers, speed-over-ground tracking and battery-management read-outs. All of that raw data needs to flow up to the Pi, where it is bundled, logged and pushed over a 4 G link. The Pi also runs the user interface on an onboard touchscreen. I want that interface to launch straight into a clean dashboard with drag-and-drop style widgets so I can rearrange or resize gauges, graphs and buttons while in the field. On the software side I need: • Firmware for the Arduino that publishes every sensor value pl...

I’m upgrading a vehicle with a roof-mounted thermal imaging camera and need a streamlined enclosure that behaves a bit like a transformer: it must rise, give the camera a full 180° pan and at least 30° of tilt, then fold back and disappear under a low-drag cover when not in use. The core of the job is mechanical design. I’m after a concept that can be built either by 3-D printing or injection-moulding, so please keep draft angles, wall thickness and other DFM considerations in mind from the outset. Weather sealing, vibration resistance and smooth airflow over the stowed housing are essential, but I’m flexible on the exact material as long as it can survive sun, rain and highway wind speeds.
