    ...all I/O for motor driver, LED ring, sensors, and battery management must be broken out. • Connectivity: Both WiFi and Bluetooth should run concurrently without external modules. • Functions to support: lighting up with LEDs, communicating with other devices, and tracking movements (likely IMU or optical flow—open to your proposal). What I need from you 1. Complete schematic in KiCad, Altium, or Eagle (your choice—exportable to Gerber). 2. 2-layer (or justified multilayer) PCB layout, routed for a circular form factor with clear mounting points for wheels and battery. 3. BOM with manufacturer part numbers and availability notes. 4. Power system: safe lithium battery charging circuit (USB-C preferred) and protection. 5. Design files ready fo...

    I’m moving from concept to bench-top reality on a new battery pack and I need an R&D hardware engineer who is equally comfortable with Battery Management Systems like Anker ...communicates over CAN and handles balancing / protection within spec – Thermal subsystem demonstrating ≤ 3 °C cell-to-cell delta at 2 C discharge in a 35 °C ambient chamber test – Full documentation set: schematics, BOM, Gerbers, thermal model and test report Note: few more modules & deliverables which I will explain over the chat. BMS & thermal management will plain main role, with other modules. Altium (or KiCad), MATLAB/Simulink, ANSYS/Icepak or equivalent should feel like home to you. If this sounds like the kind of deep-dive hardware sprint you enjoy, let’s t...

    ...a compact through-hole PCB laid out for a small consumer-electronics gadget I am prototyping. The board will stay simple—one or two layers, only a handful of standard components, no high-density routing or exotic footprints. Please take my rough hand-drawn schematic, translate it into a clean CAD schematic, and produce production-ready Gerbers. Any mainstream package such as KiCad, Eagle, or Altium is fine as long as the final files open without warnings. Deliverables • Editable schematic file • Board layout file • Gerber, drill, and pick-and-place outputs • Basic BOM with part numbers and footprints I will validate the design by loading the Gerbers into an online viewer and running DRC, so everything must pass standard clearance checks ...

    ...multi-layer board for an industrial control application. The board must respect tight mechanical size constraints and accommodate several predetermined components, so part placement and routing strategy will be critical. Here’s what I will supply: • Complete schematic and BOM with the locked-in parts • Target layer count and preferred stack-up What I expect back: • Editable PCB layout files (Altium or KiCad preferred), Gerber/ODB++ packages, drill files, and assembly drawings • Clear documentation of the layer stack, impedance-controlled traces if required, and any design rules you applied • A brief hand-off review call or annotated PDF explaining the routing choices and how the size and part requirements were met If you have a track record desig...

    ...HASL lead-free finish and follow the usual application notes: suitably wide power traces for roughly 5 A peak, a clean serpentine data path that lets me chain multiple boards edge-to-edge. (See the image) Vias, stitching and grounding strategy are at your discretion provided the board remains manufacturable at common fabs such as JLCPCB or PCBWAY. Preferred toolchain is KiCad 7; if you work in Altium or Eagle, just make sure I still receive KiCad-compatible Gerbers and PnP data. Deliverables • Gerber, drill and IPC-356 net-list files • Pick-and-place/centroid file and BOM with exact LED footprint reference • Source project in KiCad 7 (or exported equivalent) • Quick fabrication note confirming two-layer stack-up and HASL lead-free finish The design is...

    ...need a seasoned accountant to take full ownership of my sales-tax compliance in every U.S. state. The job centres exclusively on tax preparation—no ongoing bookkeeping or income-tax work—so I’m looking for someone who already knows the ins and outs of marketplace facilitator laws, state-specific thresholds and the quirks of Amazon Seller Central reports. Your role is to: • Determine and confirm nexus or filing requirements across all states and any relevant local jurisdictions • Register the business where required and keep those accounts current • Pull accurate sales data from Amazon, reconcile it (QuickBooks Online and CSV exports available), and prepare timely returns • File each return on schedule—monthly, quarterly or annua...

    ...spaces. • A low-power MCU or SoC with built-in connectivity (LoRaWAN or Wi-Fi are both acceptable; advise on the best fit). • On-board storage for buffering readings when the network drops and secure OTA firmware-update capability. • Accurate calibration routines so the environmental data is trustworthy when it reaches the cloud. Deliverables 1. Complete schematic and PCB layout files (Altium, KiCad or your preferred tool). 2. A bill of materials with realistic lead times and alternate components. 3. Production-ready firmware (C/C++, MicroPython, or Rust) capable of sampling sensors, timestamping readings and pushing packets via MQTT/HTTP. 4. One assembled prototype with test report demonstrating accuracy within ±1 °C and ±3 % RH ov...
