Creating a printed circuit board prototype — a personal project for Artem K.

Creation based on the sample drawings of a grain crusher, taking into account our experience. The sample is located near Kyiv.

A fixture for welding parts needs to be developed!!! Project description! 1. The base must be solid!! It needs to hold 5 parts! 2. It must be mounted on a rotating table!!! The table size is 1200×600; there are holes on the table for fastening the fixture with M12 threading with a grid of 200×200. The distance between the parts must be sufficient for welding corner seams using a welding robot!!! 3. The chisels must be quickly secured and well positioned!! 4. One side stop should be completely rigid (main base), from which the robot starts the program reference. The opposite stop should be movable — it can be implemented as a quick clamp (Toggle Clamp), a screw bolt, or a folding plate.5. During welding, the parts heat up. This also needs to be taken into account!

Looking for a systems engineer / DevOps / server hardware specialist to conduct profiling (resource consumption analysis) of a script on BAS and calculate the optimal PC configuration for 24/7 operation. What needs to be done: Analyze resource consumption of the script: Run the provided BAS script in different modes (for example, 1, 5, 10, 20 threads). Conduct profiling of actual consumption: CPU (Single-core / Multi-core), RAM (memory leak dynamics over a long distance), disk (IOPS / read-write), GPU / iGPU (check if there is a load on the graphics). Identify "bottlenecks" and calculate the exact resource consumption coefficient per thread. Calculate the necessary power: Provide an accurate hardware calculation for our target number of threads (for example, 50, 80, 100, 150). Provide configuration recommendations: what processor is needed (Consumer or server Xeon/EPYC), RAM size and frequency, SSD requirements (NVMe IOPS), motherboard (VRM for 24/7), and cooling. Prepare a specification for purchasing a PC: Compile a ready-made budget specification of specific components. Requirements for the performer: Understanding the specifics of Browser Automation Studio or browser automation tools (Puppeteer / Selenium / Playwright). Experience in conducting benchmarks and load testing (Stress-testing / Profiling). Deep understanding of modern hardware (DDR4 vs DDR5, PCIe lanes, VRM, server vs desktop hardware).

Technical task: Development of design documentation (DD) for thermoboxes (insectariums) Goal: To develop drawings for the production of two types of dismountable thermoboxes made of matte stainless steel for further export. GENERAL DESIGN, LOGISTICS AND QUALITY REQUIREMENTS • Operating conditions: Working temperature inside — 30°C, humidity — up to 80%. The design must be resistant to stable heating and high humidity, ensuring the tightness of joints. • Material: Stainless steel AISI 304, surface — matte. • Hygiene and smoothness: The inner surface must be as smooth as possible. Minimize the protrusion of nuts, ends of threads, or any fastening elements inside the structure. * Task for the designer: Propose fastening options (embedded parts, hidden connections, etc.) so that the inner walls are even. • Quality and appearance: Professional "commercial" appearance, absence of any gaps after assembly. • Export orientation: Assembly should be as intuitive as possible for the end user (export version). • Walls: "Sandwich" (matte stainless steel AISI 304 + basalt wool 50 mm). The thickness of the metal for the frame and cladding must be agreed upon with me. • Assembly: Easy to assemble, non-welded, with bolts (stainless steel A2/A4). • Dimensions and logistics: The basic size of the filler plates is 1000 x 600 mm. The basic dimensions of the products can be adjusted only with my approval (the customer). • Equipment and options: Legs 30 mm, lamp mounts, IR film mounts, seating places for internal racks/supports. Cable passages: Sealed, for leading wires outside. Bar for the shield. • Protective mesh: All ventilation openings are protected by stainless mesh (cell 0.8 mm, wire 0.5 mm), fixed with pressure plates without holes in the mesh itself. PRODUCT №1: Vertical box (2000 x 1200 x 800 mm) • Door construction: Double-leaf across the entire width of the facade (1200 mm), trims, rubber seal. Viewing window: Double-layer on one of the leaves, height 500 mm, pressure frames (2–5 mm). Additional "vent" at the bottom of one of the leaves. Locking — mechanical latch. • Ventilation: ◦ Lower intake: 2 openings (left and right), size 400 x 100 mm each, with dampers. ◦ Upper exhaust: Mounting place for a fan 120x120 mm on flange (M4 fastening, center distance 105 mm). The size of the opening in the "sandwich" — 200 x 200 mm. Provide for an adjustable damper. PRODUCT №2: Small box (900 x 600 x 600 mm) • Construction: Side doors across the entire panel, trims, rubber seal. Inside — removable/adjustable shelves. • Ventilation: ◦ Intake: 2 openings on the sides of 400 x 100 mm each, with dampers. ◦ Top: Mounting place for a fan 120x120 mm on flange (M4 fastening, 105 mm), opening in the "sandwich" — 200 x 200 mm. Provide for an adjustable damper. TASK FOR THE DESIGNER: Propose optimal fastening nodes, sealed passages, and a frame design without welding. Be sure to propose design options that minimize the protrusion of any fastening elements (nuts, threads) into the internal space. The goal is a reliable, sealed structure without gaps, with a professional "commercial" appearance. REQUIRED RESULT: 1. 3D models (STEP / SolidWorks) + interactive assembly (Autodesk Viewer). 2. Drawings of parts and nodes (connection diagrams, fastening of nets/glass/lights/IR film). 3. Unfoldings (DXF) taking into account bending coefficients. 4. Specification for stainless fasteners. 5. Proposals for design solutions, timelines, and costs.

Development of a mechanism for alternating the flipping of plastic cupsProject Goal It is necessary to develop only the mechanism for flipping plastic cups "every other one" for an automatic production line. The device must ensure the following sequence: 1st cup — without flipping (0°) 2nd cup — flip 180° 3rd — without flipping 4th — flip 180° and so on. As a result, the output should produce the sequence: 0° → 180° → 0° → 180° → ...What is already available The cups move along the conveyor in a single row. Before the mechanism, all cups have the same orientation (lid up). Only the flipping unit needs to be developed.Proposed Operating Principle The following scheme is considered: A dividing screw synchronizes the flow of cups. All cups gradually rotate to the position of 90°. Then, the cam mechanism acts only on every second cup. Every second cup returns from the position of 90° back to 0°. The others continue rotating to 180°. As a result, we get: 0° 180° 0° 180° If the performer offers a simpler, more reliable, or more technological solution — we are ready to consider it.Requirements1. Develop a complete 3D model in SolidWorks It is necessary to model: dividing screw; flipping mechanism; cams; guides; shafts; mountings; all necessary parts.2. Perform kinematic verification It is necessary to ensure that: the mechanism operates without jamming; there are no intersections of parts; the cups are flipped correctly; the mechanism is suitable for manufacturing.3. Conduct Simulation / Motion Study It is necessary to perform an animation of the mechanism's operation in SolidWorks Motion. It should be visible: the movement of the cups; the rotation of parts; the sequence of flipping every second cup.Work Result The performer must provide: source files SolidWorks (*.SLDPRT, *.SLDASM); assembly; Motion Study; animation video; STEP file of the assembly; drawings of the main parts.
