    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...

    My Euroart JG168BL dual-zone wine fridge is stuck on an E4 error, which points to a faulty NTC temperature sensor in the upper chamber. The sensor is easy to reach from inside the compartment and will need to be spliced in because the main board is not readily accessible. I need a technician with solid general refrigeration experience who can: • Supply a compatible NTC sensor • Remove the old probe, install and splice the new one neatly (heat-shrink or similar insulation) • Run a full test to clear the E4 code, confirm stable temperatures on both zones and listen for anything else that might need attention I haven’t ruled out other faults, so basic troubleshooting during the visit is expected. If you would rather I order the part myself, let me know—­I...

    I need a detailed on-site survey for multiple retail stores so we can confirm that our new waste compactor will fit, power up, and be serviced safely. Your report has to give me everything the installer and electrician will ask for: • Site measurements – all critical dimensions around the proposed compactor area, ceiling heights, door clearances, and any obstructions, recorded in both metric and imperial units. • Electrical requirements – panel rating, breaker space, conduit path, distance to the closest suitable connection, and clear photos of the existing service. Confirming voltage and phase onsite. • Accessibility & placement options – path of travel for delivery, turning radii, dock or grade-level access, and at least one recommended mounting l...

    I need a clear and professionally drafted electrical single-line diagram based on the electrical load list along with safety features that shows how power will be distributed throughout a small-scale gas plant facility. The drawing must follow the NEC (National Electrical Code) so that it can be submitted directly to our local authority for review and later handed to the construction team without additional rework. Scope of work – Capture the complete power distribution path from the utility tie-in through to all downstream loads, including metering points and breaker information. – Use standard electrical symbology and layer naming so I can easily integrate the file into our master AutoCAD set. A clean PDF export is also required for circulation.

    I am looking for an engineer or team that has already completed full-scale retrofits on large-format CNC equipment and can bring an HB03/TS150 JUARISTI up to today’s standards. The scope is comprehensive: the control system must be replaced, all electrical components re-engineered and rewired, and the mechanical assemblies fully overhauled so the machine leaves the shop in “as-new” condition. What matters most to me is proven experience integrating modern CNC controls into legacy iron without compromising accuracy or rigidity. If you have recently worked with Siemens, Fanuc, Heidenhain—or another controller you feel is better suited—let’s discuss the architecture you would recommend and why. Likewise, I’d like to hear how you handle mechanical scr...

    For my current university project I have to build a compact PCB whose only job is to collect data from several temperature sensors and route those readings to the rest of my prototype through simple wired connectors. Everything must be laid out and modelled inside Fusion 360, right down to the housing that will protect the board once it is fabricated. Here is what I need from you: • Create the full schematic and board layout in Fusion 360’s electronics workspace, optimised for straightforward sensor-integration and robust wired headers. • Export clean Gerber/Drill files plus the native Fusion 360 design so I can iterate later. • Model a 3-D printable enclosure in the same project file, dimensioned precisely to the finished PCB, with openings for the temperature-...

    I’m arranging a series of one-hour classes that blend hardware design (VLSI and PCB) with software development in Python and Java. My students sit at an intermediate level in both languages, so each session must go beyond basics and dive straight into advanced concepts, hands-on coding practice, and a mini project component we can build on from week to week. On the hardware side, I’d like you to break down VLSI and PCB workflows in the same practical style—show the design flow, demonstrate essential simulation or testing steps, and connect theory to real-world use cases that spark curiosity. Key details • Format: live, one-hour interactive class (screen-share, white-board or live IDE). • Pace: concise explanations followed by immediate demos or coding walk...
