I have an ESP32-D dev board and three unused PAA5100JE optical-flow sensors. I only need to bring one online first, confirm it streams clean motion data, then replicate the solution for the other two. What I already have • A sketch that compiles but never sees the sensor • All parts on hand, breadboarded and powered • Standard Arduino IDE installed on my end for quick testing What I need from you within the next couple of hours 1. Corrected or freshly written code that initializes the PAA5100JE, verifies it over SPI, and outputs X/Y delta values on the serial monitor at 115 200 bps. 2. A clear wiring diagram (hand-drawn is fine if neat, Fritzing/KiCad even better) that shows every pin between the ESP32-D and the sensor, including power, ground, CS, MISO, MOS...

The goal is to create an external overlay for Minecraft Java 1.8.9 (would be awesome if it supports 1.8.9 as well as the latest version but that's not a priority, 1.8 is) that runs on Windows and remains completely invisible to Discord screen-share and Windows Game Bar recordings while adding no perceptible latency. Because it lives outside of the game’s memory space, it must never trip basic anti-cheat checks or appear in captured footage, yet still render in real-time on my own screen. Core functionality: • Stream-proof, zero-latency overlay (top priority) • Visual mods (I'll specify once we contact) • Item and chest/storage tracking • Minimalist, key-toggleable GUI that blends with the vanilla look Technical notes: – External overlay approach...

I am building a proof-of-concept that lets a Raspberry Pi follow a user’s gaze and immediately translate that data into visual output on an attached screen. At the end of the job I want to be able to look at a point on the display and watch the system draw a corresponding dot, line, or free-hand stroke in real time. What I already have • Raspberry Pi 4 with camera interface available • Freedom to choose the most suitable eye-tracking library (OpenCV, MediaPipe, PyGaze, or similar) • One HDMI monitor for testing, though the code should remain display-agnostic so I can later swap in a touchscreen or e-Ink panel without major refactoring. What I need from you • Set up and calibrate the camera-based eye tracker on the Pi • Translate raw gaze coordinat...

My production C# application currently targets .NET Framework 4.8 and has started to show its age. I need it migrated to a supported, more secure runtime (ideally the latest LTS release of .NET), with every dependency updated and any obsolete APIs refactored. The primary driver is security: I want all outstanding vulnerabilities removed, HTTPS enforcement tightened, and modern authentication/cryptography practices adopted throughout the codebase. During the upgrade I also want to introduce a clean integration layer so the app can talk to external systems (REST and, if feasible, simple message-queue endpoints). This should be implemented in a way that keeps the core logic decoupled and unit-testable. Finally, a handful of persistent UI glitches—visual misalignments and sporadic cont...

I’m looking for a compact program that can do two things completely hands-off. First, it must analyse and solve ordinary 2D grid-based mazes on its own, selecting the shortest path with a Breadth-First Search approach. Second, once the maze is finished, the same application should detect any reward ads or pop-up videos that follow, let them run to completion, and then close them automatically so the flow never stalls waiting for a click.(this is for android btw) Speed matters to me; I’d like an initial working build as soon as possible. I’m flexible on the language and platform so long as the final deliverable runs reliably on Windows and can be triggered from the command line (no manual input at any stage). Deliverables • Executable or script with clear run inst...

I need a self-hosted script that automatically reads every new Instagram post in my feed (no restrictions to hashtags or accounts) and then leaves a thoughtful comment that ties directly to the caption’s wording. The automation must rely only on code I can run on my own machine or server—no cloud services, commercial schedulers, or other third-party apps. Core logic • Pull each fresh post and extract the full caption text. • Run lightweight text analysis/NLP to understand the main topic or sentiment. • Generate a short, human-sounding reply that feels relevant to that text. • Publish the comment instantly through the official Instagram Graph API or another method that stays within Instagram’s policy limits. Deliverables 1. Fully commented s...

LOOP every ~2 seconds, for each burner sensor independently: 1. Read current temperature from sensor 2. Add reading to a rolling 15-20 second window of recent readings 3. Compute rate of change over that window 4. IF temperature has plateaued (stayed within ~±2°C band) AND plateau duration > 10-15 seconds AND temperature >= 90°C: -> Trigger "BOILING LIQUID" alert - Sound buzzer: 3 short beeps - Send Blynk push notification: "Burner X approaching boil" - Enter cooldown state for this burner (~2 min, suppress repeat alerts) 5. ELSE IF temperature keeps climbing past ~120°C without plateauing: -> Trigger "DRY PAN / FIRE RISK" alert - Sound buzzer: continuou...

Build the computer vision system as if it were analyzing gameplay from a retail copy of the game. It must not rely on any internal game state, memory access, engine hooks, debug APIs, or hardcoded timing values. The system should make all decisions solely from the rendered video output, exactly as a player would see it on screen. The system must support two modes with a user-toggle: * Shot Meter Mode: Analyze the live shot meter visually in real time rather than using predefined release timings or static values. * Animation Mode: Analyze the player’s shooting animation to determine the optimal release timing without using the shot meter. The solution should process frames with low latency, be resilient to different camera angles, graphics settings, and jump shots, and include a ca...

I need a compact, reliable humidity-logging solution that can capture readings at regular intervals and send them straight to Google Cloud Platform in near-real time. I am open to microcontrollers such as ESP32, Raspberry Pi, or any low-power alternative, provided the final build can connect over Wi-Fi or LTE and push data securely—ideally through Cloud IoT Core or Pub/Sub—into a time-series bucket I can later analyse with BigQuery or Data Studio. What matters most is that the entire path from sensor to cloud is proven and robust. You are free to suggest the specific humidity sensor, the firmware language (Arduino, MicroPython, C, etc.), and the best authentication method for GCP, as long as you keep power consumption modest and the solution easy to reproduce. Please highligh...

I’m developing a microcontroller-based embedded system that will sit inside a vehicle (horn-relay) and act as the central hub for sensor integration and data acquisition. The core of the job is full-cycle design and development: selecting the right MCU family, creating the schematic and PCB layout, writing the firmware, and validating that the board reliably collects, timestamps, and streams data from the relay connectivity Hands-on experience in both embedded C/C++ and practical electrical or automotive environments is essential because the design must stand up to temperature, vibration, and EMI constraints found in vehicles. Familiarity with CAN, LIN, or similar in-vehicle networks is a plus; the final board will need to forward selected sensor packets to the main ECU. Deliverabl...
