Project of the grinder

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.

Project Description:I am looking for an electronics engineer for a paid technical consultation on repairing network equipment.Problem Summary:There is a 4-channel GSM-VoIP gateway GoIP4. The device has started to go into a cyclic reboot (the relays click every 2 minutes, it does not accept calls, and it resets authorization).What has already been checked:The power supply has been replaced with a known working one (12V/2A) — the problem persists.SIM cards have been removed and checked — the symptoms are the same without them.The problem is 99% likely to be in the hardware (internal power circuit on the board, degraded capacitors, or a burnt-out DC-DC converter).What is required from the contractor:Consult on typical issues with this board and suggest which power circuit elements should be checked first with such symptoms.Important: If you are located in Cherkasy (or are willing to accept the board via Nova Poshta), we can arrange for physical diagnostics and re-soldering of components as part of this project.Please respond if you have experience in component-level repair of motherboards, routers, or similar telecommunications equipment.

The type-C must match the hole on the step model : It should look impressive for the model + don't forget about the monitor output! Best on black textolite And to avoid the obvious impression that it is not working :) (for the average user) Show me the board in the case

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.

It is necessary to integrate the NCS with the automatic launch system (catapult with a microcontroller) to transmit a signal to the microcontroller, which will initiate the operation of the catapult 500 meters away from it.
