I need a custom mixed-signal circuit engineered from the ground up to drive an optical wireless communication link. The design must cleanly blend an accurate analog front-end—handling photodiode receive and LED/VCSEL drive stages—with the required digital processing blocks for modulation, clock recovery, and protocol framing. My priority is signal integrity across the entire chain: low-noise transimpedance amplification, precise ADC/DAC selection, and robust high-speed PCB layout that minimises jitter and EMI. Component choices should be commercially available and cost-effective for a small production run. Because the target is an optical wireless channel rather than Bluetooth, Wi-Fi, or Zigbee, you are free to choose or recommend the most suitable modulation scheme (e.g., ...

I already have a custom carrier board laid out, but the power section needs a quick revision—the existing regulator must be swapped for a different power regulator before we move to assembly. The current design is finalized, but one power IC is out of stock and needs to be replaced with an available alternative. I’ll provide the current schematic, layout files (Altium/KiCad), and the BOM; your task is to integrate the new regulator, verify all power-integrity considerations, update the PCB documents, and get the board ready for manufacturing again. Once the hardware files are final, I’ll need help bringing the board up in software. Specifically, I’m looking for boot-ready firmware plus the low-level drivers required for the OS I’ll be installing in-house. The...

An electrical schematic now exists only as a digital image and must be recreated as a clean, fully editable drawing. The task is strictly a redraw—no changes to the circuit itself—so every symbol, wire number, reference designator, and note has to match the original image exactly. Use any mainstream electrical-CAD platform you are comfortable with (AutoCAD Electrical, EPLAN, OrCAD, etc.); just be sure the drawing complies with standard drafting conventions and layer discipline so it can be maintained later. Deliverables • Native CAD file of the finished schematic • A print-ready PDF generated from that file Before hand-off I will spot-check key nets, component labels, and title-block data against the source image to confirm accuracy and completeness.

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...

Our sports venue runs on an ageing electronic scoreboard built around seven-segment LED and P10 LED panels. It still works, but erratically, and it can only be operated from the hard-wired control box bolted under the grandstand.
