We are looking for a physicist engineer or a design engineer with experience in developing induction chargers, Qi/Qi2, and working in KiCad. We already have: a ready-made wireless charging board for two devices; two coils for charging a phone and headphones; the case design and 3D models. What needs to be done Add a third charging channel for Apple Watch. Select and calculate the coil, electronic components, and connection scheme. Resolve the issue of correct Apple handshake and compatibility with Qi/Qi2. Check if the system can stably charge three devices simultaneously. Calculate the required power of the power supply, heating, and main electrical parameters. Consider the shielding of the coils, as the charger is installed inside a wooden case. Prepare or refine the schematic and PCB in KiCad. Provide recommendations on design, safety, and further certification of the device. We are considering two work formats: full development and preparation of files; engineering consultation with calculations and recommendations that our specialist can implement. Please, when responding, write: whether you have experience with wireless chargers Qi/Qi2; whether you have worked with Apple Watch or MFi components; whether you can perform calculations for coils, power, heating, and shielding; attach examples of similar projects.

Dmitro K. 9 JulyДоброго дня.
Чи є у вас якісь фото хоча б орієнтовно того що ви хочете чи як бачите ці вироби?

Dmitro K. 9 JulyПояснювати чому я так написав: ви схожі (або не зовсім схожі) проекти вже пропонували на сервісі, вам по них відписували і тут виходить або це щось інше або щось з минулих напрацювань не підійшло.
Як варіант пропоную "їсти слона частинами" тобто розбити велику задачу на етапи і так рухатись до бажаного результата.

Дмитрий, мне нечего показать. Предыдущие решения, которые я планировал, на порядок сложнее. На самом деле у меня будут разные варианты конструкций: мини, средний и максимальный. Я решил начать с минимального, так как были сомнения, получится ли всё воплотить. Не буду углубляться в детали, но это самое простое решение

Planning options for a shower module for military use based on 20 and 40-foot shipping containers. Various combinations are available. This is an AI-generated photo; it needs to be adjusted and smart dimensions for walls, partitions, and overall sizes applied for further manufacturing.
A gerber file is required to order a board based on the description; there is no schematic, part of the schematic (the PWM) will be drawn by hand. The set is very simple: a power stabilizer based on the ATmega 328, a 1602 display, and three buttons with a couple of small connectors.

Greetings. Development of a premium 3D model of a wooden memorial product for CNC production Project description A custom design of a premium wooden memorial product needs to be developed for further manufacturing on a 5-axis CNC. The project should not resemble classic memorial products. The main idea is a modern minimalist design. The product should look like a solid sculpture without wide frames and unnecessary decorative elements. Tasks Create a high-quality 3D model. Ensure the possibility of production on a 5-axis CNC. Design the body and lid. Consider a hidden seam line. Include hidden hinges and locks. Create an internal cavity according to standard internal dimensions. Execute the model with correct slopes and radii for wood processing. Style Minimalism. Premium design. Maximally smooth shapes. No sharp corners. No wide frames. Solid streamlined surface. Material Main material: oak; ash; walnut. Wall thickness should be suitable for manufacturing from solid or laminated wood. Result The following should be provided: STEP; STL; IGES (if possible); source CAD file; high-quality renders; drawings with main dimensions. Desired skills of the performer SolidWorks; Fusion 360; Rhino; Autodesk Inventor; Fusion CAM; experience in modeling wooden products; understanding of model preparation for CNC. Important A performer with experience in creating premium-class products and industrial design is needed. Ready to sign an NDA (non-disclosure agreement) before providing detailed technical specifications and references. Having a portfolio with complex organic or industrial forms will be an advantage.
