I have a collection of DICOM CBCT volumes exported from Sirona GALILEOS / SIDEXIS and I need a 3D Slicer extension that streamlines research-grade periapical lesion analysis. The core priority is highly accurate detection and segmentation; everything else follows from that. The workflow I picture starts with frictionless DICOM import, passes the volumes through a pre-trained model for initial lesion detection, lets the user refine or approve the mask, and then automatically computes total lesion volume in mm³. Once a baseline study is finished, the same tool should accept a follow-up scan, register it to the baseline, and output comparable measurements so longitudinal change can be plotted immediately. Key deliverables • 3D Slicer extension (Python scripted module or C++ lo...

I run a small 10x10-foot TikTok studio and I’m ready to tighten up my audio chain. All the gear is here—Shure MV7 (XLR), Elgato Stream Deck, Wave Link, OBS, TikFinity, Voicemod, and a pair of Bluetooth in-ear monitors—but I need someone to come onsite and make it all talk to each other. Here’s what I’m after: the Shure MV7 and Stream Deck must feed cleanly into TikTok Studio while also reaching my Bluetooth IEM with zero noticeable latency. The Stream Deck is mainly there for sound effects and overall audio control, so its profiles and key assignments need to be mapped through Wave Link and reflected in OBS and Voicemod without any volume jumps or channel conflicts. Physical cabling, software routing, gain staging, filter setup, and basic noise reduction all...

I already have a custom board built around an ESP32-D, the accompanying PlatformIO project, and fully working low-level drivers for Wi-Fi, MQTT, GPIO and storage. What I still need is the high-level logic that ties everything together so the device behaves like an intelligent Wi-Fi switch. Here is what the finished sketch must do: • Subscribe to a dedicated MQTT topic and parse the JSON commands coming from my mobile app. • Execute each command immediately, switching the relay output on or off and publishing an acknowledgement with a timestamp. • Monitor the on-board push-button; every manual activation should be time-stamped, stored locally, and later pushed to the same MQTT broker so that no event is ever lost if the connection drops. • Run both daily and week...

I’m running an ArduRover platform on top of a fully custom-built mission planner and would like an experienced hand to refine two specific areas: route optimization and waypoint management. The core code already communicates with the vehicle via MAVLink, but the logic that selects, orders, and dynamically adjusts waypoints is still basic. Here’s what I need from you: • Analyse the present planner codebase (Python and C++ modules) and map out its current decision-making flow. • Design and implement smarter route-selection algorithms that minimise distance, energy use, and turning radius while respecting geo-fences. • Build an intuitive waypoint-handling layer so I can insert, reorder, or delete waypoints on the fly and have those changes propagate safely ...

Our product runs on a custom embedded system and it now needs a dedicated firmware module that can handle all UART-based communication. I already have the hardware schematic and register map; what is missing is production-ready code that initializes the peripherals, manages interrupts, frames the data, and exposes a clean API the application layer can call. Here is what I need from you: • Develop clean, well-documented firmware in C or C++ that brings up the MCU, configures the UART peripheral, and implements reliable transmit/receive routines (including error handling and buffering). • Follow our existing coding conventions and keep the footprint small so power consumption stays within spec; DMA or low-power sleep modes are welcome where appropriate. • Provide a conci...
