I have a working draft of a telephony-grade hardware design and I need a seasoned electrical engineer to finish it up. I will supply the current PDFs/PCB files, and a brief block-level write-up. The files contain only basic documentation. Once we agree the hardware is sound, I’ll have a shortlist of component-level questions (why a particular codec, timing tolerance on the crystal, etc.). Clear, practical answers here will decide the final BOM. The next stage is firmware which will bring it to life. I need clean, well-documented code—preferably in C or C++—that compiles under GCC or a comparable open-source toolchain. Deliverables • Answer one question about component substitution • (Later on, next project, after I have a prototype produced) complete firm...

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, ...

I need an engineer who can design, implement, and validate a BLDC motor–control solution that maximises energy efficiency in a residential air-conditioning unit. The end result should let the compressor fan ramp up and down smoothly, draw the minimum possible power across typical duty cycles, and integrate without fuss into the existing appliance electronics. Scope of work • Develop or adapt a control algorithm (sensorless or sensored—whichever meets the efficiency target) that delivers stable torque at low RPM and high efficiency at peak load. • Select the appropriate MCU or gate-driver IC and size peripheral components so the complete design fits inside the current controller footprint of a split-type indoor unit. • Provide firmware, annotated source cod...

I need a working TIA Portal V17 project that lets me test and demonstrate basic control logic on a Siemens S7-1200. The goal is to open the file in my own installation, start PLCSIM (standard or Advanced, whichever you prefer), and watch the logic execute without errors. Scope • Create a clean project with the correct S7-1200 hardware configuration. • Write and comment the fundamental control routines I will specify once we start (start/stop, interlocks, simple timers, fault reset). Keep the code in LAD or FBD so it is easy to follow. • Set up tags and watch tables so I can toggle inputs and observe outputs during simulation. • Provide a brief note inside the project (or as a PDF) explaining how to start the simulation and what to look for. Acceptance I will...

I am building a control solution around a Siemens S7-1200 and need the complete PLC program and matching Siemens HMI screens created in TIA Portal. All logic has to compile error-free, follow Siemens best-practice block structure, use symbolic addressing, and include clear comments so I can maintain it later. Once we start I will share the I/O list, functional description, and network settings; you will return a single TIA Portal project that contains both the PLC and HMI configurations. Deliverables • TIA Portal project file (.ap13 or later) with PLC and HMI fully linked • Export of all program blocks and tag tables • Short PDF explaining program structure, tag mapping, and any special instructions • Video or simulation showing each HMI screen driving the PLC ...

I am developing a complete FPGA-based 5G NR Low-PHY platform for an O-RAN 7.2x radio architecture. The objective is to design, implement, integrate, optimize, and validate the complete real-time digital signal-processing chain rather than isolated FPGA blocks. The scope covers O-RAN 7.2x/eCPRI fronthaul processing, IQ compression/decompression, FFT/IFFT and cyclic-prefix processing, resource and antenna mapping, 2×2 and 4×4 MIMO, precoding and digital beamforming, DUC/DDC, channelization, interpolation/decimation, digital filtering, CFR, DPD, calibration, gain/phase correction, multi-carrier processing, timing/synchronization, and high-speed ADC/DAC interfaces. The engineer will be responsible for FPGA architecture, RTL/HLS/IP implementation, block integration, clock-domain a...

I need software and firmware file to download into KS98-2 process controller. No time wasters. Only contact if you have experience with West controllers.

I need to get a clear, working understanding of how my smart sensor EPD SS3-EW is programmed when it is tied into a MACH-ProZone controller over BACnet. At the moment the interface works erratically and any change I make in RC-Studio shows up unpredictably on the sensor. I want to pinpoint the programming mistakes, learn the correct sequence for mapping objects, and leave with a repeatable method that I can apply on future jobs. The work will happen remotely: I can share the current RC-Studio project, all trend logs, and live screen-share access to the controller and sensor. You will walk me through each step, explain why the sensor is failing to respond, and illustrate the proper way to build the BACnet objects, write the logic blocks, and push updates without locking the device. Delive...

I have an ESP32-S3 board fitted with an ES8311 codec and a small speaker. During a short face-to-face session (about one to two hours) I want to: • Install and test the Arduino core, LVGL graphics library, and the ES8311 audio driver on the board. • Load a few sample audio files, then demonstrate recording through the codec and playing the captured audio back through the speaker. • Connect the board to a public or user Wi-Fi network and verify reliable internet access. We will meet somewhere around Sheikh Zayed; let me know what location works for you, your earliest available time slot, and the cost for the visit. I can be reached directly on 01228834534 to finalise details. Bring whatever tools you need (laptop with Arduino IDE, USB-to-Serial cable, etc.) and be ready...

I have a Yale electric rim lock already installed and I want to take it a step further by adding three parallel ways to open it: a keypad PIN, an RFID tag/card, and a biometric fingerprint reader. The main driver is day-to-day convenience for family and frequent visitors—no more fumbling for physical keys—so the solution has to be fast, reliable, and easy to maintain. Here’s the scope in practical terms. I need a compact control module—Arduino, ESP32, or any other microcontroller you feel best fits—wired to the Yale lock’s strike mechanism. It must read all three credentials, decide locally, then trigger the solenoid without noticeable lag. A small OLED or LED feedback indicator and a relay or MOSFET driver for the lock should be part of the circuit. Po...
