Buna ziua! Numele meu este Alexandru Gabriel CRETU TORICA. Locuiesc in Spania la Madrid unde am deschis o firma, Gabriel's Market si ca activitate principala avem Productia de mase plastice prin injectie ( producem carcase pentru aparatele electronice si electrotehnice ) si ca activitate secundara avem productie de Smart card-uri . Deoarece vrem sa implementam o tehnologie noua de comunicare a Smart Cardurilor, avem nevoie de construirea unui device care deja a dovedit punctele slabe a tehnologiei EMV. Acest device nu se mai poate cumpara si se poate doar reconstrui, avand publicate toate detaliile necesare pentru construirea si utilizarea acestui aparat. Va trimit acest mesaj deoarece as dori sa stiu daca puteti contribui la acest proiect , macar in construirea perfecta a partii elec...

I’d like you to spend a few minutes on our e-commerce site, browse through the full catalog—electronics, clothing & accessories, plus home & kitchen—and then leave a concise, 2- to 3-line review that feels completely natural.

Clear, data-backed decisions matter to me more than flashy design tricks. Acceptance criteria for the project: • A fully functional online store...

I need a compact electronics module for a pair of driver’s sunglasses that automatically switches an LCD lens between dark and clear. When entering a tunnel, the tint should clear instantly; when in sunlight, it should darken again. The module must include a light sensor, a small microcontroller, and a driver for the LCD tint lens. It has to be very small so the sunglasses look completely normal — everything must fit inside a standard sunglasses arm. You do NOT need to supply the frame. I will provide my own sunglasses, but if you prefer, you may also use a simple interchangeable demo frame for the prototype. Deliverables: one working prototype, simple firmware, and a small assembled PCB

I need a clean, responsive Shopify site that behaves much like an Amazon Storefront but funnels visitors to Amazon through my affiliate links. The catalogue will showcase all kinds of deals—electronics, fashion, books, anything with a solid discount—so please set the product feed and collections to handle a broad mix of categories. The main organising principle should be discount percentage. When someone lands on the homepage I want them to see clear break-outs such as “Up to 30 % Off”, “40 – 60 % Off”, and so on, rather than the typical “Electronics” or “Clothing” tabs. That sorting logic has to carry through to search filters, collection pages, and any promotional banners. Key points to hit: • Ever...

...temperature and battery voltage, advertise the data, then drop straight back to sleep. For the enclosure I’d like a mixed plastic-and-steel approach to balance weather resistance with price, though I’m open to going fully plastic or fully steel if you can prove a clear cost or performance benefit. A display is optional; please architect the electronics so a display header can be added without redesigning the core board. Key deliverables • Complete electronics package: schematic, PCB layout, Gerbers, pick-and-place files, tested BOM with unit cost targets. • Embedded software: well-documented, low-power BLE firmware with a simple characteristic map and parameters to adjust the measurement cycle. • Mechanical files: enclosure CAD, gasket de...

I would like to re-design our current enclosure which houses 20 x 21700 batteries and some electronics (image attached). The new enclosure must be no larger and will be a similar design. I was thinking of a "capsule" type design (see image, new ) where the battery and BMS would slide into the larger part and the wires and electronics go into the lid. These 2 parts will connect electrically via push fit connectors but I need some way for them to stay together, maybe like a ramp lock ? I will only consider if you have worked on similar enclosures before. If you have experience with snap-fit / screw fix lids, or other clever fastening ideas, feel free to propose them—just keep manufacturability in mind. I’ll review the first concept for fit; once that&rsq...

After each item is live, take a quick screenshot as proof. Once the listings are up, move over to the website form and enter the identical information (I’ll provide the URL, login, and a short set of field-by-field instructions). You’ll send me confirmation screenshots or email...

I’m building a compact, battery-powered wearable that pairs a BLE-enabled microcontroller with several low-frequency coil drivers. The core of the job is to turn my draft architecture into a production-ready design and a working, bench-tested prototype. The electronics must be laid out in KiCad and optimized for a slim wearable footprint. Clean power is critical, so you’ll need to design low-noise regulation and filtering, advise on tight EMI shielding, and route for minimal crosstalk between the MCU, the driver stage, and the antenna. On the firmware side, I need a lightweight C/C++ stack that exposes all key settings over Bluetooth Low Energy. The companion mobile app will run on both iOS and Android, so please structure the GATT profile and command set with cross-pl...
