    I need a complete set of KiCad schematics drawn from scratch for a fairly large, multi-board concept. The job is limited to the schematic stage—no PCB layout—yet the design is dense, with a high component count, multiple power rails, and several digital-analog interfaces that must be kept well organised through hierarchical sheets. I will supply a first batch of parts: CPUs, power converters, key connectors and a few specialised ICs, each with its electrical characteristics and a preferred footprint. The remaining devices—discrete passives, protection components, odds-and-ends ICs—still need library symbols created or matched to existing KiCad libraries, along with suitable footprints. Whenever information is missing, I will point you to the relevant datasheets; yo...

    I’m building a compact entertainment gadget dedicated to high-quality audio playback and I need a complete PCB designed from scratch. The board must meet all the usual consumer-electronics constraints—low noise, minimal power draw, reliable mass-production tolerances—and fit inside a small enclosure that I will share once we start. Here’s what I expect from you: • Schematic capture based on my block diagram and component preferences • Optimised multilayer board layout with proper ground-plane management for clean audio paths • Gerber, drill and pick-and-place files ready for fabrication • A clearly organised BOM with current, purchasable parts and viable alternates • Brief design notes explaining critical decisions (impedance contro...

    Multimodal Cargo Tracking

    I’m putting together a straightforward location-tracking system for loads of non-perishable goods that move through warehouses, trucks, and rail cars. The core requirement is real-time position updates from departure to storage, with automatic alerts if a device signals potential theft. The hardware can be either single-use—so the receiver never has to return or recharge the tag—or a reusable unit that we can redeploy after each trip. I’ll need your help scoping both variants and producing an estimated cost per device for each. What I expect from you • A concise technical proposal outlining the recommended tracker form factor, network technology (e.g., GSM, LTE-M, NB-IoT, LoRaWAN), and back-end platform or API you plan to leverage. • A table or brie...

I’m equally open to renewable-energy twists, smart-grid perspectives or IoT-driven approaches if they help the work stand out. What I need from you is twofold: 1.

    hello, as part of our development process, we are experimenting with pcb design by Ai in kicad (mainly kimi k3 and konnect mcp). We can test ideas quickly but then design are less than optimal (to say the least) So, we would like to hire a person that is willing to review and fix the project to make it really fabrication ready. We would like to hire by the hour as we cannot know upfront what the effort is going to be for any given pcb, sometimes the project is not bad, sometimes it's terrible. So, if you are not familiar with freelancer. Com desktop app to track the hours, Pleaee do not bid. This is an ongoing project as we have several projects like this.

The current schematic is still in its initial draft, but I have already documented every functional block, net constraint, and mechanical boundary in a detailed requirements PDF that I will share as soon as we start.

    AP_Periph CAN Battery Monitor
    4 days left
    Verified

    I’m looking for an embedded-systems engineer who can take ArduPilot’s AP_Periph codebase and turn it into a robust CAN-bus battery monitor. The unit will sit on a DroneCAN network and stream full MAVLink telemetry, so it can slot straight into my existing ground-station setup without any extra protocol bridges. Integration with other telemetry options such as or SmartPort isn’t needed right now. Key functions I must see on the bus: • High-accuracy individual cell voltage for every cell in the pack (not just pack voltage) • Hall-effect current sensing that stays linear and low-loss all the way to 400 A • Standard AP_Periph health, identification and parameter handling so the flight controller recognises the device instantly Deliverables 1. Schemat...

    I need a complete electromechanical and IT-infrastructure design that can be certified as both Tier II and Tier III, with every subsystem clearly documented so the owner may choose the appropriate tier room by room. The scope spans power, cooling, fire protection, low-voltage cabling and network layouts, packaged as coordinated drawings, single-line diagrams, equipment schedules and a narrative that explains how each topology meets its respective uptime requirement. Power architecture must provide true N+1 redundancy—covering utility feeds, generators, UPS strings, switchgear, PDUs and branch distribution—while remaining scalable should we later migrate parts of the floorplate to 2N. Your documentation should reference Uptime Institute criteria, TIA-942, relevant IEC/NFPA code...
