    Complete Two-Car Garage Drawings
    22 hours left
    Verified

    I already have a preliminary floor plan and elevations for a detached two-car garage; what I still need is a full set of construction-ready drawings that I can submit to my local building department and hand to the contractor. Scope of work Please take my sketches and develop clear, code-compliant sheets that cover the structure from the footing up. That means foundation plan, wall and roof framing, roof plan, sections, details, door and window schedules, notes—everything normally expected in a residential permit set. Electrical requirements I would also like you to add a basic electrical layout. Nothing elaborate: just show circuit runs, panel location, switches, and fixture symbols. The garage must include dedicated 120 V outlets along the workbench wall for power tools, ceil...

    Altium PCB Update & JLC
    6 days left
    Verified

    I have three existing Altium Designer projects that must be refreshed before the next manufacturing run at JLCPCB. Both the schematic and the board layout need attention. On the schematic side I already know the exact edits: a handful of parts have to be added or removed, several nets must be reassigned, and a few voltage- and current-related values updated. Once those changes are in place the PCB layouts have to be brought in line—rerouting where required, keeping the original board outlines and mechanical constraints intact, and making sure every DRC/ERC check comes up clean. When the files are solid I need a full, ready-for-upload manufacturing package: • Updated Altium project files (.PrjPcb, .SchDoc, .PcbDoc) • Gerber and NC-Drill set generated with JLCPCB’s ...

    Dont send me AI content . I am using AI detection to check your proposals I need an engineer who knows both Pro-face Blue projects and Beckhoff TwinCAT HMI Server inside out. The task is to take my existing Pro-face HMI application, study how every screen, alarm and data point works, then rebuild the same functionality in the Beckhoff HMI environment so it talks smoothly to a new Beckhoff PLC. You will start by reviewing the current project files I provide, mapping all tags, recipes and alarms. From there, recreate the screens, navigation and any underlying logic in TwinCAT HMI. Along the way I expect you to flag any behaviour that will need re-thinking in Beckhoff, suggest work-arounds, and implement them. Because the line cannot afford long downtime, I want the converted HMI fully test...

    I have an Arduino-based board that is powered from its own DC rail, yet it has to monitor several other DC lines whose grounds are completely separate. Right now I’m simply feeding each line through a voltage divider, and—unsurprisingly—the readings jump around or drift because the grounds are floating. The symptom is clear: inaccurate voltage readings that make the data unusable. What I need is a clean, reliable way to sense those isolated DC voltages without tying the reference points together. Whether that means introducing isolated amplifiers, optocouplers, tiny transformers, or another proven technique is up to you; I’m open to whichever approach gives stable, repeatable results and keeps the measurement side safe for the microcontroller. Here’s what I&...

    I need help turning three off-the-shelf modules now sitting in my glasses prototype—a USB 2.0 hub, a USB audio codec (mic plus stereo out) and a dual-channel Class-D amplifier—into one long, narrow board that can slide inside the temple arm. The space I have measured is roughly 80 mm × 15 mm, so the layout has to be linear rather than squarish, with components placed to keep the height profile as low as practical. The board will run exclusively from the host’s 5 V USB rail; no batteries or additional supplies are planned. Because this is for voice prompts and basic media playback, a standard-grade codec is fine—I’m not chasing audiophile specs, just dependable microphone input and clean stereo output that won’t hiss or pop when the amp is idle. A...

    A new Siemens-based material-handling line is ready for commissioning and I need a clean, well-structured PLC project that focuses on data acquisition and logging. The controllers are Siemens S7 (TIA Portal) and the HMI layer will sit on WinCC (Unified or Classic—whichever you are most comfortable with). Core objective Capture and store real-time Operational status from drives, conveyors, and sensors so that maintenance and performance dashboards can draw from a reliable historical database. Inventory levels and movement tracking may be added later, so please structure tags and DBs with scalability in mind. Scope of work •⁠ ⁠Write the PLC logic that collects the required status bits, words, and alarms. •⁠ ⁠Build WinCC screens for live visualization, manual overrid...

    I have six Brax RX2 amplifiers, one Brax DSP, several small electronic accessories and a pair of secondary batteries that all need to live together in a single, cohesive rack inside my vehicle. What I’m after is a complete CAD design that shows exactly how every piece will mount - actual size of each amplifier is 310mm x 200mm x 56 mm Material preference The structure must be a wood frame with acrylic highlights. Design priorities Aesthetics come first. Smooth lines, balanced symmetry around the six identical amps, a tasteful reveal for the DSP, plus discreet compartments or channels for the accessories and batteries so no loose wires are visible once the rack is in place. At the same time, I still need adequate ventilation clearances and service access, so hinges, removable p...
