    I want a thorough, professional security check on two devices—one Android and one iPhone. I have seen unexpected apps or activities, rapid battery drain, and the occasional suspicious pop-up, so I need to confirm whether either handset has been compromised and, if so, understand exactly how to fix it. I have never sideloaded software outside the official stores, but I still want everything verified. Your task is to run a full forensic-level audit: scan for malware or spyware, inspect system logs for unauthorized access, review current privacy and security settings, and highlight every vulnerability you uncover. Please work only under my explicit authorization and within all legal boundaries. Deliverables • A clear, step-by-step report explaining findings for both device...

    We're developing a premium smart case for the iPhone 15 ("Techs") housing a custom PCB, battery, ESP module, and a 1.69" TFT display (240×280, ST7789) positioned beside the camera. This is a real hardware product going to manufacturing — not a concept render. We need the complete enclosure design taken all the way to production-ready files. Scope — full enclosure design: Precisely fitted to iPhone 15 dimensions (camera module, buttons, ports, charging alignment) Body + lid + internal PCB housing + battery compartment + display window Slim, pocket-comfortable profile despite housing electronics iPhone-recognizable silhouette (camera cutout, optional Apple logo visibility) Our brand logo ("Techs") engraved/embossed or othe...

Storage: Replace ST-TF-003A with MSD-3-A (MicroSD slot). Power: Integrate a charging circuit for a 3.7V 2000mAh LiPo (JST connector) with USB-C input for charging. Note: The board will only be used on battery power (not while charging), so we can omit galvanic isolation to save space. The USB-C input must also be wired to program the ESP32.

The core tasks include designing the full analog front-end (pulser/receiver, low-noise pre-amp, gain control, anti-alias filters), selecting and driving the piezo transducers, and implementing a precise time-of-flight algorithm in an embedded platform. I am open to ARM, DSP, or FPGA solutions as long as we can achieve micro-second timing resolution and keep power draw low enough for a battery-powered unit. On the digital side I will need firmware that triggers the pulse, captures echoes through a high-speed ADC, processes the signal (envelope detection, filtering, thresholding), and converts flight time to velocity with temperature compensation. A simple menu-driven interface on a small LCD/OLED plus USB-C data output should round out the user experience. Because th...

    Prototype: fully mechanical, dial-actuated hand. We are developing a fully mechanical (non-motorized, non-electronic) prosthetic hand prototype, actuated by a single large front-facing rotary dial. Rotating the dial clockwise closes the hand into a grip; rotating anticlockwise releases it. There is no battery, motor, or electronics in this version. Mechanism: • One dial drives one worm gear, which drives one worm wheel and tendon spool (this part matches the reference image). • The spool pulls five separate tendon lines in parallel, one per finger, each routed through its own low-friction pulley path to an adjustable anchor near the fingertip. • Each finger's knuckle joints are spring-loaded toward the open position.

    ...aesthetics, following a clean, sleek and modern language similar to Apple’s AirPods case. Key points I want you to keep in mind: • Aesthetics come first. Smooth lines, no visible screws, and a seamless lid-to-body transition are essential. • Injection-mouldable plastic will be the manufacturing method, so wall thickness, draft angles and split lines must be respected. • Hinges, magnets and the charging port cut-out must remain flush and unobtrusive. • A small LED window and a subtle logo area should be integrated without breaking the minimalist flow. Deliverables: 1. Two to three concept directions presented as high-quality renders. 2. One final, production-ready CAD model (STEP or IGES) plus STL for rapid prototyping. 3. A brief DFM note out...

    Project Golden Eagle couples solar, a lithium-ion battery energy storage system and gas-fired reciprocating engines into one behind-the-meter plant that will offset our facility’s demand charges and provide resilient back-up power. The preliminary economic model is complete; what remains is a construction-ready electrical design that folds the three resources into a single, code-compliant package. The generation mix is fixed—solar arrays, BESS and gas engines—as confirmed in our internal feasibility study. I already have detailed equipment specifications, protection philosophies and utility interconnection requirements; these must be reflected verbatim in the drawings and calculations you prepare. Where gaps appear, NEC 2023, IEEE 1547 and local AHJ amendments sho...
