Abstract: Manufacturing-Ready 130nm CMOS Inverter Design The objective of this project is to design, verify, and prepare a standard CMOS inverter for fabrication using the SkyWater 130nm Open-Source PDK. Unlike theoretical projects, this work follows a complete "Silicon-to-GDS" flow. The process begins with Schematic Capture and Pre-Layout Simulation to establish electrical baselines. This is followed by Physical Layout, where the geometric structures of the NMOS and PMOS transistors are manually drawn according to strict foundry Design Rule Checks (DRC). The design is then validated through Layout vs. Schematic (LVS) to ensure physical-electrical equivalence. Finally, Parasitic Extraction (PEX) is performed for Post-Layout Simulation to account for real-world wire resistance and...

I already have a working PCB built around an Xsens MTi-630 IMU and an NXP MKV56 microcontroller. What I need now is a technician who can revise the existing firmware so the remote camera head delivers rock-solid motion compensation on set. Your task is to design and embed a custom sensor-fusion routine that blends gyro, accelerometer, and magnetometer data from the MTi-630, then feed that fused orientation into the motor-control loop over CANopen. I’m aiming for a balanced mix of speed and accuracy so operators never feel lag yet still enjoy drift-free performance during long takes. You will be starting from my current codebase (MCUXpresso / NXP SDK), which already handles basic hardware abstraction and CANopen messaging. The focus is on: • Writing or adapting a quaterni...

I need an experienced electronics/PCB engineer to design a reliable, 24/7-operating traffic light controller PCB. This is a safety-critical system (not a hobby project).

I have a Siemens IOT2040 already running Node-RED and two flow-meters that expose their readings over Modbus registers. I need a clean flow that polls those two devices, keeps the register map exactly as it is, and republishes the same data over Modbus TCP so a Crimson-based PLC on the other side can read it without extra parsing or scaling. There is no data pre-processing involved: whatever the meters expose is what the Crimson PLC must see. All I’m after is a reliable bridge with tidy, documented Node-RED nodes and comments so future edits are easy. Deliverables and Remote Work: 1- I will provide access to Red node and computer connected to the IOT - work can be done remote connection or on your workstation then imported here, 2- There will be UIs on the Node Red to see wh...

Project Title: Electrical Engineer – Design of Universal Duplex Pump Control Panel Project Overview: We are developing a standardized duplex pump control panel to be sold as a commercial product worldwide. The goal is to finalize professional electrical engineering drawings, schematics, and a build-ready package for a compact control panel that operates two 3-phase pumps up to 25HP. The panel must be designed as a universal platform that can operate at 208/230V or 460V using simple component changes (conversion kits), without redesigning the control system. This is a product-development project, not a one-time building job. ⸻ Scope of Work The electrical engineer will be responsible for producing a complete construction-ready design package based on provided specifications, inc...

I need an engineer to take my concept for a high-voltage DC-DC converter and translate it into a complete, build-ready design that slots straight into a renewable-energy storage setup. The converter will accept 24 V DC at the input and deliver a regulated 165 V DC output. Efficiency, thermal management, and long-term reliability matter far more to me than squeezing every last cent out of the BOM, so component quality and sound topology choices come first. You will own the full electrical design flow—topology selection, key-component sizing, magnetics specification, control strategy, and all supporting calculations. I expect LTspice or an equivalent simulation environment to demonstrate stability, transient response, and efficiency before we move on to hardware. Once the numbers look...
