I’m building a smart irrigation setup that links a Raspberry Pi edge server with several ESP32 nodes in the field. Each ESP32 gathers data from soil-moisture probes, compact weather boards (temperature, humidity, barometric pressure), and inline flow meters, then reports everything wirelessly to the Pi for processing. Here’s what I need from you: • Python (Raspberry Pi) and MicroPython/C++ (ESP32) code that ingests the raw sensor streams, pushes them through an on-device model, and decides—within seconds—whether to start or stop the main pump and which solenoid valves to open. • An ML pipeline: training notebooks, a lightweight model (TensorFlow Lite or similar) and the inference wrapper that runs locally. The model must act on current soil-moisture rea...

I’m building a small bionic butterfly that “flips” in mid-air, powered by an ESP32-S3 Super Mini. What I still need is the full control system: firmware for the board plus a cross-platform mobile app that drives two micro-servos through a joystick interface. Here’s the flow I’m picturing: • The ESP32-S3 runs custom firmware (Arduino IDE or ESP-IDF—whichever you prefer) advertising itself over BLE. • The mobile app—working on both Android and iOS—connects, shows a virtual joystick, and streams position data in real time. • The board translates that data into precise PWM signals so each servo can beat the wings smoothly and synchronously. I will supply the hardware (ESP32-S3 Super Mini and servos) for your testing if nee...

I would like a full TFET study carried out in Cogenda Visual TCAD that covers both 2-D and 3-D device representations. My end goal is to arrive at a structure—and a small demonstration circuit—whose operating point clearly illustrates ultra-low power consumption. Here’s what I need from you: • Build the TFET geometry in the tool, choose appropriate materials and doping profiles, then sweep critical design parameters until the device meets a low-power operating target (sub-threshold swing and leakage will be the key figures I’ll look at). • Run complete electrical simulations in 2-D first, then extend the validated setup to 3-D so I can compare dimensional effects. • Supply all Cogenda project files, meshes, command scripts, and export any pl...

I have a finished KiCad PCB layout and now need a clean, print-ready PDF compiled from it. The final document must contain six A4 landscape pages arranged in this exact order: 1. Copper Top Layer 2. Copper Inner Layer 1 3. Copper Inner Layer 2 4. Copper Bottom Layer 5. Component Placement Top Layer 6. Component Placement Bottom Layer Resolution has to be crisp enough for both close-up review and high-quality printing. I’ll provide the KiCad source files as soon as we get started; you simply export each required layer, keep KiCad’s default rendering colours, and merge them into a single PDF. I’ve attached a previous example—please note the labels are mirrored on that file due to an earlier issue, so yours should read correctly. Deliverable • O...

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...

I have an air-quality monitor prototype on breadboard and now need a production-ready PCB. The core of the board will be an Arduino Nano, linked to Wi-Fi for cloud logging and OTA updates.

I have safety sector time-series dataset that combines three synchronized streams: sensor imagery, textual maintenance logs, and high-frequency numeric readings. The objective is to forecast future values—not merely detect anomalies—so grid operators can anticipate demand, equipment stress, and renewable supply fluctuations.

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 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...

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...

I’m putting together a dedicated, distraction-free reading device and need a hardware specialist who can take it from concept to working prototype. The display has to be an AMOLED panel of at least 11 inches—no compromises on that vibrant contrast. This will be a reading-only tablet, so efficiency, eye comfort, and battery life have priority over raw processing power. Wireless connectivity is essential for loading books and updates; Wi-Fi is mandatory, Bluetooth is optional. In addition, I want physical page-turn buttons on the bezel so users can flip pages without touching the screen. Touch input itself is welcome but not a requirement. Here’s what I’m expecting from you: • Source and validate the 11″+ AMOLED display and its driver board • Desi...
