...a solid 3D model I can push straight to a printer. The core purpose is surface sanitization, so the design must clearly integrate both UV-light emitters and a disinfectant-spray system. The robot should be able to manoeuvre through a typical patient room or office and “see” everything you would expect inside—chairs, tables, desks, sinks and similar fixtures—so please include outward-facing sensors (LIDAR or depth cameras are fine) in the shell design to communicate that capability. Overall aesthetics can stay simple and functional; I’m more concerned with clear component placement and printability than flashy styling. Please make this very simple and easy looking. I don’t want it to look professionally done. I want it to look like an amateur...
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.

I want to bring to life a lightweight iPhone app that can recognise scratching episodes just from the handset’s own motion sensors—primarily the accelerometer and gyroscope. My vision is for everything to be processed on-device so the user’s data stays private, yet I’m open to exporting raw events to a small backend later if that proves cleaner for post-processing or model updates. For detection I’m leaning toward a hybrid approach: a simple rule layer to filter obvious noise and an embedded Core ML model to learn the subtler patterns. Push notifications should warn the user whenever their scratching crosses a configurable daily threshold, and a single screen will show the time-stamped events plus a rolling daily and weekly summary. A basic settings vi...
I have a clean AutoCAD master file and clear mark-ups that show exactly where each speaker, wireless access point, camera, and lighting keypad belongs on every floor. What I need now is a polished set of four separate drawings—one for each device type—where those points are inserted on every floor plan and identified with standard industry symbols and call-outs. The locations are already determined, so this is primarily a drafting and annotation task: copy the base plan, drop in the symbols at the marked coordinates, label them in a way any integrator will immediately understand, and keep the layers tidy so the elements can be toggled on or off later. Deliverables • Four DWG files (Speakers, WAPs, Cameras, Keypads) reflecting all floors • Matching PDF...
