Good evening! It is necessary to assemble a lamp using electronic components that are sold in the USA, specifically on specialized sites. If you can design the casing where these components will be inserted - great, if not, that’s fine too. The components need to be selected so that minimal effort is required for connection. Two options are needed: Option 1: A bedside lamp that can be charged via USB-C in 2-3 hours and the charge lasts for at least 100 hours of operation + battery discharge indicator + touch activation. Option 2: The same but with added Wi-Fi and connection to smart home systems like Google/Amazon Alexa and others + the ability to charge via wireless charging, so include wireless charging. Work stages: 1. Provide a list of components and connection instructions to assemble without designing the casing. 2. We assemble the model and check that it works. 3. We close the project.
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.
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.
Task: create a prototype adapter that will allow the use of tool brand A on video processor brand B. There are two brands of endoscopes (camera on a flexible tube), let's call them brand A and brand B. Each system consists of a video processing unit (video processor) and a working tool that has a CMOS sensor installed. The analog signal from the CMOS goes through wires via its own connector (each brand has its own) into the video processor, then the video is transmitted to the monitor via HDMI. Hypothesis 1. Both endoscopes use the same CMOS. We know for sure that model A uses the OV6946 sensor (https://www.ovt.com/products/ov6946/). Visually, sensor B looks similar to sensor A. Hypothesis 2. It is possible that video processor B has a different polling or synchronization protocol. Hypothesis 3. Initial experiments with simple "color-coded" wire connections did not yield results. Therefore, it may be necessary to develop a matching board. What we provide: working tools A and B (2 pieces each, can be disassembled). Video processor B (can be carefully opened). Connectors A and B. Video processor A - under question. Requirements: experience with CMOS, signal analysis using an oscilloscope, development of signal processing circuits, assembly under a microscope (the conductors are very thin, have a shield and a central core). The image quality should not noticeably suffer! The prototype must be reliably assembled and suitable for transportation. Result: working prototype on a breadboard, documentation (circuit, description). Deadline from the moment of receiving materials: 2-3 weeks Propose a cost.

It is necessary to design a mechanism for the remote opening of hopper lids (railway grain car) at an operating elevator. The unloading area has a roof and allows for unloading on 2 tracks simultaneously. The system must move from both sides of each track and have dimensions of 60 cm in width (there is a separation system that does not allow exceeding the specified dimensions). The system must be installed and move exclusively along the floor along the track and the movement of the cars (a suspended system cannot be implemented). The power supply is electric 380-220V, and the actuators can be either electric or hydraulic; pneumatics are not considered. The mechanisms for opening the lids have 2 types depending on the type of car, and also different locations for the locks themselves. The system must open and close the locks and have a video surveillance system for positioning the working organ that will open the hatch and move back and forth. The operator is located at a distance of 150-250 m and there is also the possibility of manual control next to the mechanism or from a remote control. I am attaching a diagram of the hangar, drawings of the aspiration layout, and analogs of the mechanism from an American manufacturer.
