I have just purchased my neighbour’s central air-conditioning system and need a qualified HVAC professional to handle the entire transfer. The unit must be carefully dismantled at the neighbour’s property, moved next door, and fully installed at my single-family home. Once in place, I also want it tested, charged if necessary, and given a quick maintenance check so I know it is running at peak efficiency. You will receive the exact brand and model details upfront so you can bring the right fittings, line-set length, refrigerant, and electrical hardware. The two houses sit side-by-side with unobstructed driveway access, which should make transport straightforward; however, I still expect proper recovery of any remaining refrigerant, safe handling of electrical connections, and ...

I have a university automation assignment due on 22 June that revolves around Siemens NX Mechatronics Concept Designer linked to TIA Portal. Rather than wrestle with my half-finished model, I’m open to whichever path gets a reliable result fastest—either salvaging the current files or standing up a brand-new virtual station. Core requirements • Build a small station in NX MCD that includes sensors, actuators and a clear behaviour sequence. • The primary manipulation task must be cylinder actuation; if a second motion makes the logic easier, we can discuss. • Create the matching PLC program in TIA Portal, test it in PLCSIM and prove the handshake between the two environments. • Deliver a working simulation that meets the course rubrics and can be dem...

I need an experienced network specialist to tune the performance of my Local Area Network. The primary focus is network optimization—pinpointing and eliminating the throughput bottlenecks that are slowing users down during peak hours. Here’s the flow I have in mind: first, you will remotely review the existing topology, switch configurations, VLAN design, and cabling maps. After running traffic captures and SNMP or NetFlow baselines, you’ll present a concise report showing where bandwidth is wasted or mis-prioritised. Once we agree on the findings, you’ll put the fixes in place—whether that involves QoS adjustments, firmware upgrades, or smarter port-channeling—and then verify the improvement with fresh metrics.

What I expect from you: source or fabricate a plate that meets standard gang-box sizing for three eyhernet connections. Crimp Please confirm the plate material, color options, and lead time when you reply, and note any mounting hardware you plan to include. White playe just need ends crimped connected to router and a white plate with three hook ups. Wire is already there

Scope of Work & Deliverables 1. Circuit & Component Simulation Validate and simulate critical sub-circuits and component behaviors before moving to the layout stage (using LTspice, PSpice, or equivalent). Optimize the power delivery network (PDN), specifically the integration between the HLK Network module and the ESP32, ensuring proper noise filtering, decoupling, and voltage stability. 2. Schematic Review & Optimization Comprehensive audit of the existing schematic for signal integrity, protection circuits, and component ratings. Ensure proper implementation of hardware protection (e.g., TVS diodes, fuses, surge protection). 3. Thermal Simulation & Management (High Priority) Perform full Thermal Simulation (FEA/CFD) of the PCB and components under continuous 24/7 work...

I have just completed my Electrical Engineering degree and I’m eager to let the world know what I can do, but I’m stuck on where and how to start. Social media feels like the right arena for showcasing my work, yet the options are overwhelming and I’m unsure which channels will truly help me connect with recruiters, project owners, and potential clients. Here’s what I know so far: • I definitely want to focus on social media rather than traditional job boards or purely professional networking sites. • I’m open to freelance-oriented spaces alongside the usual industry platforms. • The core content I plan to share is my portfolio and the projects I have already completed—circuit designs, simulations, and prototype builds. What I need f...

أعمل على تجهيز نظام مراقبة يعتمد بالكامل على كاميرات IP ثابتة، وأحتاج إلى دعم فني في مرحلة التجميع وربط هذه الكاميرات بسويتش الشبكة. اخترت استخدام كاميرات ثابتة من شركة معينة، لذلك يهمني أن تكون لديك خبرة سابقة مع إعداد هذا النوع من الكاميرات وتهيئتها على شبكات PoE أو سويتش مُزوَّد بالطاقة. المطلوب منك هو إرشادي خطوة بخطوة في: • تثبيت الكاميرات فعليًا وتوصيلها عبر كابلات Cat6. • ضبط عناوين IP وتكوين الشبكة بحيث تتعرف جميع الكاميرات على السويتش بسلاسة. • التأكد من ظهور البث في برنامج المراقبة أو الـNVR بعد الاختبار النهائي. • تقديم مخطط شبكة مبسّط يتضمن المنافذ المستخدمة وأرقام IP للتوثيق المستقبلي. أتطلع إلى حلول عملية ونصائح احترافية حول أفضل الممارسات في اختيار الطاقة، البروتوكولات المدعومة، وحماية الشبكة (مثل عزل VLAN إذا لزم). إذا كانت لديك خبرة سابقة مع ا...

I need to continuously sweep the local RF spectrum and flag any transmission that is not licensed for this area. The focus is on detecting unauthorized signals—specifically illegal broadcasts—rather than general interference or pattern anomalies. Your task is to design and prove a monitoring workflow that can: • capture live spectrum data with a reliable SDR front-end (RTL-SDR, HackRF, USRP or similar), • compare detected carriers against the public allocation tables I will supply, and • raise a timestamped alert whenever an unapproved carrier appears or drifts into a protected band. I am comfortable handling hardware procurement; what I need from you is the RF engineering know-how and software integration. Experience building spectrum-monitoring or S...

This project establishes a completely new Aruba-based LAN and wireless infrastructure for our corporate headquarters, designed to serve between 100 and 500 employees from day one while leaving room for future growth. Scope of Work • Produce a detailed architecture that combines Aruba CX access/core switches, campus access points, and Mobility Conductors / Controllers. • Map out VLANs, routing, QoS and PoE budgets, ensuring seamless wired-to-wireless roaming. • Create an RF plan that balances coverage and capacity across open areas, meeting rooms and executive suites. • Develop configuration templates (AOS-CX & AOS-10/AOS-8 as appropriate) and switch/router/controller startup configs. • Integrate with existing services such as DHCP, RADIUS/AD and gues...
