    For my project, I seek a freelancer skilled in image processing, particularly in recognizing LED lights within an image. • Main Task: The primary job revolves around detecting objects in images. More specifically, these objects are LED lights, and they can often exhibit varying levels of brightness due to their pulse-width modulation (PWM) frequency. • PWM Frequency Range: Your role will require you to focus on medium range PWM frequency, that is, between 100Hz and 1KHz. This stipulation is crucial, and your ability to recognize these frequency patterns will inform the success of this role. • Expertise: Proficiency in computer vision libraries and algorithms along with an understanding of LED brightness will be ideal. Familiarity with complex image pr...

Specifically I...efficiently within a short detection range of up to 1-2 meter. Specifically I am using the MSP432P401R microcontroller and ADALM2000. Expertise in the specific microcontroller is not that important. You should have experience with microcontroller in general, working with general-purpose input/outputs (GPIOs), analog-to-digital converters (ADCs), timers, periodic interrupts and Pulse-Width Modulation (PWM). Understanding of C programming and microcontroller robotics is essential. Only software help is needed. Hardware is...

    I'm looking for a professional in solar panel installations to work on a comprehensive project for a residential house. The project will involve the installation of 8 - 10 panels on both the house and in the backyard. I already purchased 8-10, 365-watt, mono panels, with an EG4 6000 XP 120/240 inverter, and two EG4 48v LL-S batteries. I'm looking to power a 3.5 ton mini-split with off-grid solar. I'm not looking to power the entire home at this time. Key Requirements: - Determine the best positioning for the panels to optimise sunlight and power output. - Advise on and install necessary infrastructure. I am not currently aware of any existing solar panel infrastructure in my home. - Recommendations needed: In terms of brands or models, I have no specific prefer...
