I need a working proof-of-concept that hardens my wireless network by analysing live traffic and flagging hostile activity the moment it appears. The model must reliably catch the attacks that worry me most: Denial of Service (DoS), Man-in-the-Middle (MitM) intrusions, classic packet sniffing, and ARP spoofing. Everything has to run in real time on a modest on-prem machine, so efficient feature extraction and lightweight inference are a priority. The task breaks down naturally into three parts. First, capture and label representative WLAN traffic—public datasets are fine as a starting point, but I also want a small tool that lets me pipe raw pcap streams into the training set so the system can learn my network's quirks. Second, build and train the detection engine: a wel...

Key objectives • Develop architectural and structural drawings that translate the modern aesthetic into a practical build. • Integrate energy-efficient amenities (high-performance windows, insulation strategies, efficient HVAC) without driving material costs beyond standard options. • Plan for wired and wireless smart-home infrastructure—security, lighting, climate control—so the installer can drop the systems straight in. • Produce 3D exterior and interior renderings to verify massing, daylight, and room flow before permits are filed. Acceptance will be based on the completeness of stamped construction documents, coordinated MEP schedules, and BIM/Mod...
I need an end-to-end solution that lets me monitor and, when necessary, remotely control a set of environmental sensors that report temperature, humidity, and air-quality data. Here is the flow I am envisioning: the sensors push readings to the cloud (MQTT, HTTPS, or another lightweight protocol you prefer), the data is stored and processed, and a desktop application then visualises the live feed, keeps historical logs, and lets me define threshold-based actions. Key points I care about • Real-time monitoring and control is the primary goal—latency needs to be kept low and reconnect logic must be solid. • Sensors involved: temperature, humidity, and air quality. The system should be flexible enough to add more sensor types later without a rewrite. ...

I’m rolling out a Python-based platform that keeps an eye on city roads in real time. The first goal is clear: monitor live video from roadside traffic cameras, spot congestion, accidents or blockages within seconds, and push actionable alerts through a cloud-hosted pipeline.

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 &bul...

I’m building a live remote-monitoring dashboard that ingests MQTT messages from a teltonikak rtu 901 gateway along with temperature, pressure, and oxygen sensors and many other parameters from a controller. The stack I have in mind runs on DigitalOcean or AWS and is driven by Python on the back-end and JavaScript on the front-end, but I’m happy to discuss refinements if you can justify them. Current status • Devices is yet to publish raw readings over MQTT. • No cloud pipeline, storage layer, or UI exists yet. What I need next • A lightweight yet secure ingestion service (Python is preferred) that subscribes to the topics, validates payloads, and writes them to a scalable store on DigitalOcean. • A real-time dashboard in JavaScript that show...
For my current university project I have to build a compact PCB whose only job is to collect data from several temperature sensors and route those readings to the rest of my prototype through simple wired connectors. Everything must be laid out and modelled inside Fusion 360, right down to the housing that will protect the board once it is fabricated. Here is what I need from you: • Create the full schematic and board layout in Fusion 360’s electronics workspace, optimised for straightforward sensor-integration and robust wired headers. • Export clean Gerber/Drill files plus the native Fusion 360 design so I can iterate later. • Model a 3-D printable enclosure in the same project file, dimensioned precisely to the finished PCB, with openings for the tempe...
