Electrical Mechanical Switch for Knife

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.

I am looking for a designer to prepare working drawings for exhibition stands. I need a person with experience working with composite materials, who understands their capabilities and limitations, and knows how to properly design parts for milling and production. The task is to create technical drawings, including visualizations: assemblies, sections, dimensions, fastenings, specifications, and other data necessary for the construction manufacturing. It is preferable that the candidate already has experience in exhibition stands, advertising, or decorative constructions and can offer practical, technological solutions for production. Here are some examples of the direction to move in: https://www.instagram.com/market_tablo https://www.instagram.com/crealle/ https://www.instagram.com/artefinal_brasil/ https://www.instagram.com/rahbardesign/ https://www.instagram.com/kiancogroup.cnc/ Attached photos also include samples. In the PDF - the design that needs to be tested currently. It is not guaranteed that this project will be confirmed and go into production, but I need to understand the designer's approach. In any case, the test will be paid. The working area of the milling machine is 2100*4100 (vacuum table and automatic tool change with 7 positions).
