FM-transmitter for 433 MHz (BFR93W transistor, electret mic front end, bias and tank network). What I need now is a compact, production-ready layout inside a 13.5 mm circular, 2-layer board that I can share with a PCB house without further edits. Everything will be done inside an EasyEDA Shared Workspace; once you send me your EasyEDA username I’ll make you an editor so you can work directly on the live project. The priority is to minimise interference while respecting the strict size limitation, critical component placement around the RF path, and tight signal-routing clearances. If you’re used to controlled-impedance traces, short RF loops, and grounding tricks on tiny boards, you’ll feel right at home. Deliverables I expect at hand-off: • Finalised EasyEDA desig...

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 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.

I maintain a fleet of mission-critical electronic control boards that must run flawlessly around the clock. Although the hardware is operational, I want to squeeze every last drop of performance out of it and harden the supporting security stack. Your focus will be on two fronts that matter most right now: • Bench-testing the optocouplers and comparators on the boards, then fine-tuning or replacing any part that introduces noise, latency, or inconsistent thresholds. RS-485 paths are already stable, so your insights should drill straight into these analogue front-end components. • Re-creating my SOC lab scenarios, walking through the logs, alerts, and incident chains, and flagging bottlenecks or mis-tuned rules that slow response time. Packet captures, SIEM exports, and a fu...

I have a production-ready, IGBT full-bridge welding inverter that already powers both TIG and MMA processes, yet the embedded side still needs a final expert pass before release. The control board is built around 8051 and STC MCUs running Keil C51 firmware, and every line of code directly shapes arc stability, HF start, AC balance, soft-start, and safety interlocks. The short-term goal: review, tidy, and extend the existing code so it drives the power stage flawlessly in TIG and MMA, AC and DC. That means refining PWM timing, gate-drive dead-time, current-feedback filtering, and all the little state-machine details that separate a decent welder from a great one. Core tasks and deliverables • Audit the present C51 codebase, flagging race conditions or timing pitfalls. • Im...

I’m putting together a small interface that lets a 5 V logic line drive a 12 V DC mechanical relay while keeping the control electronics completely isolated from the field wiring. My plan is to repurpose an off-the-shelf two-channel relay module for the load side and pair it with a standard optocoupler breakout on the control side; you can choose whichever optocoupler best meets the brief as long as it fits the isolation goal. What I need from you is a concise, ready-to-build circuit design: • A clear schematic showing the 5 V input network, the optocoupler stage, any necessary current-limiting or pull-down components, fly-back diode protection for the 12 V coil, and the wiring to the relay board. • A bill of materials with exact part numbers so I can order everything imm...
