    Mecanismo LED Giratorio POV

    已验证

    Quiero materializar un display POV (persistence-of-vision) con un anillo de LEDs que, al girar, proyecte gráficos nítidos y coloridos. Ya tengo claros los conceptos básicos, pero necesito a alguien que lidere la ejecución, con énfasis en el mecanismo de rotación y balanceo. Lo que espero de tu trabajo • Diseño del conjunto rotativo: eje, soporte impreso en 3D • Integración de slip rings: es la opción que prefiero para alimentar el sistema y evitar que los cables se enreden durante la rotación. Necesito la selección del modelo, su montaje y pruebas de continuidad. • Selección y acoplamiento del motor (DC o stepper, según convenga) con su controlador para lograr un giro suave y unif...

    I have already chosen the core components for a compact mixed-signal board that will consolidate several sensors—a barometric pressure sensor, a nine-axis IMU, a GPS/GNSS receiver, and a simple power-status monitor—into one surface-mount module along with a controller chip. Your task is to translate those parts into a complete schematic, turn the design into an SMD-friendly PCB, and run thorough simulations so I can be confident in its behaviour before we move to prototypes. The board’s sole purpose is sensor integration, so clean routing between the analogue front-end, digital lines, and any required power-conditioning blocks is critical. I’m comfortable if you work in Altium, KiCad, or another mainstream CAD package, as long as the final files are ready for fab...

    I’m putting together a microcontroller-based inverter for industrial equipment and need an engineer to translate my specs into a production-ready design. The goal is a rock-solid 300 W pure sine wave output, stepping from a nominal 350 V DC input down to 200 V AC. Low total harmonic distortion is essential because the unit will drive sensitive industrial controls. You are free to choose the MCU family you’re most comfortable with (STM32, PIC, MSP430, or similar) as long as the firmware is well-documented and the control algorithm delivers a clean sinusoid under varying loads. Efficiency, thermal performance and fault handling must be considered throughout the design. Deliverables • Complete schematic in Altium, KiCad or Eagle • PCB layout files ready for fabricati...

    Request for quotation for the complete hardware design of an electronic board based on ATmega2560, intended for industrial PCB production (PCBWay or similar manufacturers). The scope of work includes hardware design and industrialization only; firmware development is not included. The request includes the document “Preanalysis PIN OUT scheda ATMEGA2560”, which is an integral and binding part of the project specifications and must be followed strictly. The document defines the MCU pin mapping and the type of signals assigned to each pin, including: • digital inputs • digital outputs • digital inputs with PWM function • PWM outputs • analog inputs (0–10 V) • PT100 inputs • encoder inputs using interrupt-capable pins • SPI int...

    I have a small AGV platform running on an Arduino Uno, two DC motors driven by an L298N bridge, and a pair of HC-SR04 ultrasonic sensors mounted up front. I already have the hardware wired and tested; what I still need is clean, well-documented embedded-C code that lets the robot detect an approaching obstacle with the ultrasonics and autonomously steer around it. Functionality • Primary mode must be obstacle avoidance; no line following or remote-control features are required at this stage. • When the sensors report an object within the safe-distance threshold, the robot should smoothly adjust course and continue forward rather than simply stopping. A simple state machine or PID-based turning logic is fine as long as the movement looks deliberate and repeatable. Implementa...

    I need a full, permit-ready electrical plan set for a new accessory dwelling unit. I’m starting from scratch—no prior schematics or panel schedules exist—so the drawings must cover every circuit, device, and code note from the service entrance to the final outlet. The ADU will run on a typical residential load-mix (lighting, receptacles, basic kitchen appliances) plus a layer of smart-home and security wiring. Please incorporate the low-voltage runs, conduit paths, and any dedicated controller panels so the inspector sees everything on one coordinated sheet. Deliverables I expect: • Load calculations and panel schedule sized for both standard and smart devices • Complete single-line and wiring diagrams, including breaker and conduit sizing • Lighting,...

    I have a water-treatment skid that recirculates water through a bank of pumps and an ozone generator, then sends the finished stream to storage tanks. The attached schematic shows the valve logic and motor loads; what I need now is the brains. Task You will select a compact, readily available PLC (or other basic logic controller) that can: • sequence three pumps dedicated to water circulation, • run the ozone generator on a programmable timer, • switch flow to the final storage tanks once ozonisation is complete, • provide hard-wired manual-override switches, and • report simple status via LED indicators (no touchscreen or text LCD). Once the hardware is chosen, write and supply the ladder/structured-text program with annotated source code. Finally, a...
