Hello! I need advice on selecting ready-made components for a small project. The task is to implement two functions: 1. Automatic raising and lowering of a wooden roof using an electric motor. ( plywood size 60x40cm) 2. Turning on and off internal LED lighting. It is important that I am specifically interested in selecting compatible ready-made components without soldering and developing electronics. I want to build a system from ready-made modules with connectors or terminal connections. I need help with the selection of: ● a suitable motor; ● a power supply; ● switches or limit switches; ● a controller (if necessary); ● buttons or other control elements; ● cables, connectors, and other necessary components. I would like to receive a list of specific parts that can be ordered, so that after purchase, it will only be necessary to connect them together and install them in the product. I would appreciate advice and assistance in selecting the optimal solution. I will send more details in a private message.

Task: create a prototype adapter that will allow the use of tool brand A on video processor brand B. There are two brands of endoscopes (camera on a flexible tube), let's call them brand A and brand B. Each system consists of a video processing unit (video processor) and a working tool that has a CMOS sensor installed. The analog signal from the CMOS goes through wires via its own connector (each brand has its own) into the video processor, then the video is transmitted to the monitor via HDMI. Hypothesis 1. Both endoscopes use the same CMOS. We know for sure that model A uses the OV6946 sensor (https://www.ovt.com/products/ov6946/). Visually, sensor B looks similar to sensor A. Hypothesis 2. It is possible that video processor B has a different polling or synchronization protocol. Hypothesis 3. Initial experiments with simple "color-coded" wire connections did not yield results. Therefore, it may be necessary to develop a matching board. What we provide: working tools A and B (2 pieces each, can be disassembled). Video processor B (can be carefully opened). Connectors A and B. Video processor A - under question. Requirements: experience with CMOS, signal analysis using an oscilloscope, development of signal processing circuits, assembly under a microscope (the conductors are very thin, have a shield and a central core). The image quality should not noticeably suffer! The prototype must be reliably assembled and suitable for transportation. Result: working prototype on a breadboard, documentation (circuit, description). Deadline from the moment of receiving materials: 2-3 weeks Propose a cost.

Need a contractor for the development of UAV avionics of aircraft type We are looking for a specialist or team to develop the electrical schematic and prepare the equipment specifications for UAVs of aircraft type. Scope of work: development of the principle electrical schematic of the onboard system; selection and specification of all electronic components and equipment; description of connections and interfaces between components; preparation of a set of technical documentation. Requirements for the performer: experience in developing electronic systems for UAVs or robotic complexes; knowledge of modern component base and electronic design tools; experience in preparing technical documentation. Please send information about relevant experience, examples of completed projects (if possible), and estimated timelines and costs for the work.

A compact electro-mechanical control unit needs to be developed: a motor-reducer for connecting to an existing mechanism of gears and rails, controlled by a key with smooth lighting activation. Switch key - the mechanism is such that the key is inserted into the lock - different key turns trigger different actions. 1 - turning on/off the lighting 2 - starting the mechanism for lifting the covers A motor needs to be selected that will ensure smooth movement of the gears: The entire structure is 60x60 cm, and a small motor needs to be attached, along with miniature lighting. Part of the space for this is ready - if it's not enough, we will come up with a solution based on your recommendations.

Need a professional engineer to calculate and design a modular trailer platform with a load capacity of 60 tons for a ready-made chassis. There are factory drawings. Changes need to be made.
