Project Title: FPGA-Based Real-Time PCB Defect Detection and Localization Project Description: I am looking for an experienced freelancer to assist with the development of my ECE final-year major project, titled “FPGA-Based Real-Time PCB Defect Detection and Localization.” The objective is to develop an FPGA-based system that detects and identifies the locations of visible defects on printed circuit boards (PCBs). The proposed system should compare a reference PCB image with a test PCB image and use image-processing techniques to detect differences that indicate potential defects. Required Features: 1. PCB image acquisition or loading of sample PCB images. 2. Image preprocessing, including grayscale conversion and thresholding where appropriate. 3. Reference and test image...

I need an audio-based AI that takes plain text and returns a natural-sounding English voice output. The end goal is a production-ready text-to-speech (TTS) engine I can integrate into web and mobile apps. Here is what I expect as the finished work: • A trained TTS model (neural or parametric) optimised for clear, human-like English speech • An inference script or lightweight API endpoint (Python/Flask or Node preferred) that accepts text and streams back audio (MP3 or WAV) in real time • Simple usage documentation plus a quick demo project showing how to call the service Acceptance criteria • Latency under two seconds for a 200-character string on a standard GPU instance • No noticeable robotic artefacts at common sampling rates (22 kHz or higher) &bu...

need a small IoT device built that can read data from a Selec 500 UCI PID controller through its RS-485 Modbus port and send those values automatically to a Google Sheet via Wi-Fi. The device should: 1. Use an ESP32 board (low-cost, Arduino-compatible). 2. Take input from the RS-485 port of the Selec PID using a MAX485 module. 3. Host a Wi-Fi setup page (so user can enter SSID & password). 4. Send the PID readings (PV, SP, and OP values) every few seconds to a Google Sheet (via a Google Apps Script endpoint). 5. Work on 5V DC or USB power. 6. Be housed in a small project box or DIN rail enclosure for industrial use.

I am seeking a freelancer to write well-commented template that turns an Adafruit Feather ESP-32 single board computer into a tiny WebSocket server. Later I will expand that template into a mini OCPP (Open Charge Point Protocol) server and add more functionality. The target board is the Adafuit ESP32-S2 Reverse TFT with a ST7789 display. The deliverable is a tiny compile ready package on the complexity of the example at * Boots up and serves out a small HTTP web page for testing. * Each browser client can send a number to the tiny server via websockets. * The tiny server stores each number persistently. * The tiny web server flashes each received number on the built in TFT display. * The tiny web server returns the total number of numbers logged back to the browser clients, whi...

Custom 3-PIR GSM Anti-Theft Security Alarm with SMS, Call & Relay PROJECT DESCRIPTION: I am looking for an experienced embedded hardware and firmware developer to design and develop a custom human motion / anti-theft security alarm using an ATmega328P (Arduino-compatible) microcontroller. The device will use 3 external PIR motion sensors connected to the main PCB through long cables. The main feature is a selectable PIR detection threshold of 1, 2, or 3 sensors. This will help reduce false alarms. MAIN PIR LOGIC: The device has: * PIR 1 * PIR 2 * PIR 3 The user can select the required number of PIR sensors that must detect movement. Threshold 1: Any one PIR becomes active = intrusion confirmed. Threshold 2: Any two PIRs become active = intrusion confirmed. PIR1+PIR2, PIR1+PIR3...

I need a simple, single-board PCB layout created from an already completed and fully tested Fritzing (.fzz) project. The circuit logic, components, and pin mappings are 100% verified on a physical breadboard. This is a very quick micro-task for an experienced electronics engineer. The design is an ultra-low-power Smart Irrigation Sensing Node using an all-3.3V power architecture. Key Specifications & Pin Mapping: • Microcontroller: Arduino Pro Mini (3.3V variant) • Radio Module: LoRa Ra-01 (Antenna area must be kept completely clear of copper traces and ground planes). Pin connections required: NSS to D10, RST to D9, DIO0 to D2, plus standard hardware SPI lines (D11, D12, D13). • Power Input: Direct 3.2V LiFePO4 Battery connection to the Arduino VCC rail (Bypassing the ...

Hi, I need a schematic and PCB design for my college project, an Automatic Soap Dispenser with Low Soap Level Detection. I am using: - Arduino Nano V3.0 (ATmega328P) - TTP223 capacitive touch sensor - XKC-Y25-V non-contact liquid-level sensor - Kamoer KPHM100-HB peristaltic pump — 12 V, 0.5 A - LED for low-soap indication - Pump driver circuit Operation: When the TTP223 is touched, the Arduino Nano should activate the 12 V peristaltic pump for a programmed amount of time and then stop it. The XKC-Y25-V will be mounted outside the soap container at the low-level point. When the soap becomes low, the Arduino should turn on an LED. The Arduino must not drive the pump directly. Please include a suitable transistor/MOSFET pump-driver circuit and flyback protection. The pump uses 12 V, ...

Chcę ożywić mój ekran Waveshare, wyświetlając na nim własną animację. Posiadam gotowy plik GIF, lecz wymaga on konwersji do formatu obsługiwanego przez Arduino. Mogę dostarczyć grafikę także jako JPEG lub PNG. Twoje zadanie: • Przekonwertuj mój GIF (lub wersję JPEG/PNG) do formatu akceptowanego przez bibliotekę. • Napisz przejrzysty, dobrze skomentowany szkic Arduino, który odtwarza animację na ekranie Waveshare. Kod powinien działać na standardowym środowisku Arduino IDE i korzystać z dostępnej biblioteki.
