A project needs to be developed for a large park composition in the shape of a cat and a mouse based on the attached visual reference. The figures will be installed outdoors in the park area and will serve as a decorative art object and photo zone. The base of the figures should be made of a sturdy metal frame. The outer covering is planned to be made of artificial grass or another weather-resistant material. Approximate dimensions of the cat: — total length — 8 m; — height of the head — 3.24 m; — height at the withers — 2.34 m; — width of the body — 2.4 m; — length of the head — 1.8 m. Approximate dimensions of the mouse: — total height — 1.8 m; — body length — 0.81 m; — height at the withers — 1 m; — total width with ears — 0.9–0.95 m. What is required from the performer: Develop an artistic 3D model of the two figures while adhering to the specified dimensions and proportions. Prepare visualizations from several angles. Design the internal supporting metal frame. Plan for dividing the large figure into modules for manufacturing, transportation, and assembly. Prepare working drawings of the metal structure with dimensions, profile cross-sections, connection nodes, and attachment points. Develop a method for securing the structure to a concrete base or foundation. Consider wind, snow, and operational loads. Provide specifications for the metal and the approximate weight of the structure. Provide recommendations for anti-corrosion protection, external covering, delivery, and assembly. The figures will be permanently outdoors, so the structure and covering must be resistant to rain, snow, frost, sun, and temperature fluctuations. Formats of the result: — 3D model in STEP, SolidWorks, Blender, or another agreed format; — drawings in PDF and DWG/DXF; — material specifications in PDF or Excel; — renders in JPG/PNG. We are looking for not just a 3D visualizer, but a specialist or team with experience in designing real metal structures. In your proposal, please indicate: — the cost of 3D modeling; — the cost of engineering design and drawings; — timelines for completion; — the software in which the work will be done; — examples of similar projects; — whether you can also organize manufacturing and assembly. The images are a reference. The final design can be adapted and made original.

Good afternoon, at this stage, we need all plans and facades in dwg. It is very important that the dimensions are accurate, especially for the exterior.

Dear designers and creators of functional wooden furniture, I present to you a mini-project. 1. General Information Subject: Development of detailed drawings for the manufacture of two single beds by custom order with bedside tables. Number of products to be manufactured: 2 (two). 2. References Use the provided photographs (files 1.png, 2.jpeg, 3.jpeg) as visual and conceptual basis. Design: minimalism, massive elements, clean lines, emphasis on the natural texture of wood. 3. Technical Specifications and Dimensions 3.1. Bed and Mattress: - Mattress size: 1000 x 2000 mm. - Mattress height: 160 mm. - Sleeping place height: Designed considering the height of the bedside tables (500 mm). - Base for the mattress: Orthopedic frame with beech slats. The frame construction (rails) should include reliable internal supports for the installation of the slatted base. 3.2. Bedside Tables (freestanding): - Dimensions: Width — 460 mm, Depth — 500 mm, Height — 500 mm (proportional to the height of the bed). - Configuration: Two rows of pull-out drawers. The tables are independent elements and are placed in front of the side panels of the headboard. 3.3. Headboard: - Height: 1400 mm. - Total width: Calculated (Width of the bed + 2 widths of the tables at 460 mm + technological gaps). Approximately: ~1920-1950 mm. - Installation: The headboard is attached exclusively to the bed frame and is an integral part of it. Mounting to the wall is strictly prohibited. - Structure (4 components): - Upper part: Wide horizontal panel across the entire width of the structure. - Two side parts: Vertical panels located behind the bedside tables. Central lower part: A panel located directly behind the mattress and adjacent to the bed frame. 4. Materials and Hardware 4.1. Materials: 100% solid wood. All parts are made from solid wood: visible bodies, facades, headboards, as well as internal boxes of all drawers. Replacements (MDF, particle board) are not used. Finish: Matte transparent varnish. 4.2. Hardware: - For all drawers of the bed and tables, use hidden mounting guides (e.g., Blum Movento, Hettich AvanTech/Actro or analogs). - Opening mechanism: "Push-to-open". No external face hardware (handles) is provided. - Fastening hardware must be hidden where possible and ensure maximum rigidity of the massive structure. 5. Structural Requirements (Assembly/Disassembly) - The product must be designed based on the principle of a modular constructor. - Fasteners (bed connectors, mini-fixes, confirmats, etc.) must ensure easy and intuitive assembly on-site, as well as the possibility of repeated disassembly without loss of rigidity and damage to the wood. 6. Requirements for the Designer/Constructor's Work Result The contractor must provide: - 3D model / Visualization of the developed structure - Complete set of working drawings (front, top, side views with all dimensions). - Assembly diagram of the nodes (especially the connection of the 4 parts of the headboard with the bed). - Specification (detailing) of materials indicating the dimensions of each solid wood part. - Specification of hardware (exact list and quantity of guides and fastening elements). - I also expect questions from you regarding the project regarding the possibility of making up to 4 revisions from my side. Additionally, as a test task, which will also be paid, it will be necessary to design a hexagon shelf. Shelf size Width 350 millimeters Height 400 millimeters. Depth — 130 mm Material: wood (Ash and Beech) Thank you for considering this Mini Project Offer.

Title: Development of electrical schematics (EasyEDA) for data acquisition modules (STM32, precision ADC, galvanic isolation) Task Description: We are looking for an experienced circuit engineer to develop the schematic diagrams for two boards (PCB design is not required at this stage). What needs to be designed: Master module: power input of 24V and communication with the external world via hardware-isolated RS-485. Analog input module: digitization of two channels of industrial sensors (0-10V / 4-20mA). Based on a precision ADC (type ADS1248). A mandatory condition is the presence of an internal digital isolation barrier after the ADC. The boards communicate with each other via SPI. Key requirements (Strict!): Environment: only EasyEDA (Pro or Std). Components: 100% of parts must have part numbers (C-parts) from the LCSC Electronics catalog, as the boards will go for automated PCBA. Base MCU: STM32F103 (or your suggestions for modern equivalents). A detailed, well-written technical specification with a ready reference architecture from Texas Instruments will be provided to the candidate. Bonus: For the specialist who diligently and competently completes this stage (circuit design), a second paid stage — routing of these printed circuit boards (PCB Design) — will be guaranteed.
