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.

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.

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.
