I’m modeling a VLSI circuit’s behaviour entirely through simulation and want to drive the process with an XGBoost Multi-Output Regressor. The goal is to replace portions of a traditional SPICE run with a machine-learning proxy that can predict multiple analog metrics at once (delay, power, noise, etc.) from layout-level or netlist-level features. Key details • Scope: pure simulation workflow; no verification or post-layout optimisation tasks are needed. • Model choice: XGBoost Multi-Output Regressor is fixed. • Critical tweak: I need a custom number of estimators rather than the default setting; help me decide and implement the optimal value through systematic tuning. What I expect from you 1. Clean, reproducible Python (preferably a Jupyter Notebook)...

Hi I will share the details with the shortlisted candidates. Thanks

I need a compact yet reliable firmware package that runs on a Renesas micro-controller and speaks IEC 60870-5-104 end-to-end, pushing device-status updates through a Quectel EC200 cellular modem straight to our cloud endpoint. My goal is simple: every change of state inside the field unit must be encoded in the IEC104 frame set, transported over the EC200’s TCP stack, and arrive at the server in near real time for further processing. The data flow is strictly one-way for now—no remote controls—so the focus is on efficient, loss-tolerant transmission and clean reconnection handling after drops. Key points you should feel comfortable with: • Renesas toolchain (e² studio / GCC) and HAL drivers • Full or lightweight IEC104 implementation, including AS...

Our industrial-grade controller combines a microcontroller core with supporting FPGAs, and the current firmware (running on an ARM Cortex-M3/M4) needs expert attention. I have several issues to resolve—intermittent peripheral hangs, timing glitches in high-speed I/O, and a few missing features that must be added without disrupting production uptime. Scope of work • Analyse the existing codebase, identify root causes of the observed faults, and document findings. • Refactor or patch the firmware so it runs reliably on the Cortex-M3/M4. • Optimise interrupt handling and DMA transfers where latency is critical. • Provide clear, commented source code plus a concise change-log so the in-house team can maintain it. Toolchain & environment Keil uVision an...

need a complete, working wall-mounted device that monitors live fire/EMS dispatch radio and displays each call in real time — built, assembled, and shipped to me ready to plug in. Full written spec (PDF/Word) will be shared with serious applicants. What it needs to do: Capture live audio from a specific radio frequency using an RTL-SDR dongle (or a live internet audio stream as a fallback) Detect when a page-out/tone-out occurs (two-tone alert followed by voice) and record that clip Play the captured audio out loud through a speaker in real time Run lightweight speech-to-text on the clip to pull out just the call type (e.g. "structure fire," "possible stroke") — not a full transcript Poll a public incident RSS feed and match the new call by timestamp to pull...

I need an experienced electronics specialist to replicate a monitoring sensor device demonstrated in a YouTube video. The device primarily monitors proximity and motion data. The device uses an ld2450 and seeed xiao2350 and a 2.42in l2c display. The video has links to the source code and wiring diagram but the diagram and video leave out core info to do it myself (such as wiring in the switch etc...) Video: Key Requirements: - Replicate the device accurately as shown in the video - Ensure it monitors proximity/motion data (e.g., distance, speed) - Use quality components for durability and reliability Ideal Skills and Experience: - Proficiency in electronics and sensor technology - Experience with video-based project replication - Attention to detail and strong problem-solving skills ...

I’m building a battery-powered prototype around an ESP32-S3 and need a rock-solid wiring diagram before I assemble anything. Once we start, I will share a complete list of sensors and modules, but you can assume they will be driven from a 9 V rail that must be stepped down where necessary. My priority is clear pin assignments, clean power routing, and reliable level-shifting so every device behaves exactly as intended. Your task • Draw a schematic / wiring diagram that shows every connection between the ESP32-S3, the sensors, any required regulators or level-shifters, and the battery interface. • Specify the exact GPIO pins you choose for each signal and explain any rationale or constraints. • Indicate decoupling, protection components, and connector types where...

I’m building an on-premise platform that runs physics-informed digital twins on high-performance, specialized Edge AI computers already installed throughout a commercial building. The goal is simple: reduce energy use while keeping occupants comfortable, all in real time. Here is what I need from you: • A complete autonomous control loop that ingests live sensor data, runs the digital twin locally and pushes commands back to HVAC and lighting subsystems. • Digital-twin models able to deliver all three key functions: ‑ Predictive maintenance ‑ Energy consumption analysis ‑ Environmental monitoring • Code written primarily in Differential Swift. If a low-level module truly benefits from C, C++ or Python, I’m open to mixed-language solutions, but S...

I have a small desk clock with a beautiful vintage edge-lit display, a bank of mechanical relays, and an Arduino doing the time-keeping. Unfortunately my first build was amateur—cold joints everywhere, wires stuffed into screw terminals, no strain relief.... Then a housemate dropped it. A friend at a makerspace has begun soldering bulbs in the propper layout to match the display but only completed the bulbs for 1 digit. They also started a ribbon connector for the bulbs to the relays/arduino/power section. I’d like you to finish the bulbs, get them connected, then cleanup the Arduino/gps-receiver/power section so it's mounted and ready for a case. I already 3d printed the display mount. • Flawless soldering on every connection, preferably on tidy perf-boards or a ...

My ESP32 Dev Module refuses to return anything when I send AT commands to a SIM800L red board. The wiring follows the usual guides: GPIO27 to the SIM’s RX, GPIO26 to its TX, grounds tied together, the SIM powered directly from a single 18650 cell. I’ve triple-checked every jumper and even dropped a 1 kΩ resistor on GPIO27 and a 2200 µF capacitor across the SIM’s Vcc–GND rails—still silence. I’m compiling the sketch for the standard “ESP32 Dev Module” target in the Arduino IDE and the board is on a direct USB cable to my laptop. Serial monitor shows the commands leaving but not a single character coming back. If you know this pairing well, I’m looking for hands-on guidance that quickly pinpoints what I have overlooked&mdash...

I want to create an educational kit that walks adult learners through building one complete, Raspberry Pi–powered project from start to finish. The emphasis is on doing, not just theory, so the kit must arrive with every component clearly labelled, concise instructions, and clean, well-commented Python code that a first-time Pi user can run without frustration. Here is what I need from you: • A bill of materials with sourcing links for all parts, cables, sensors, and accessories. • A wiring diagram (Fritzing or similar) showing every connection to the Pi’s GPIO. • Step-by-step assembly and configuration guide written in plain English, supported by photos or screenshots. • Ready-to-run code hosted in a public Git repository plus brief explanations ...

I’m working with a Diode Laser Board and I need a custom receiver that can plug into that setup, track the machine’s positioning in real time, and instantly flag any faults it detects. The idea is to have continuous monitoring so I can see where the laser head is at any moment and receive automatic alerts if something drifts out of spec or a component misbehaves. Ideally, the receiver will take positioning data straight from the board, process it with minimal latency, and expose a simple interface—serial, USB, or another protocol you recommend—so the data can be displayed live on a host PC or microcontroller dashboard. Reliability is critical, so built-in error detection should cover signal integrity, unexpected motion, and any other obvious fault conditions you id...
