I am working on a compact RF application based on Silicon Labs’ SI4010 transmitter and now need a fresh set of expert eyes to get it production-ready. The hardware is already roughed-in and the core firmware skeleton is compiling, but performance still falls short of our targets in range, spectral cleanliness, and power efficiency. Your task spans three focused areas: • Schematic & PCB audit – flag layout, matching-network, or decoupling choices that could be detuning the front end. • Firmware tuning – refine register settings, timing, and wake-sleep sequencing in the SI4010 API so we hit our duty-cycle and current-draw goals without sacrificing link reliability. • Validation – document improvements with spectrum-analyzer plots, RSSI ver...

Project Requirement: AmiBroker – OpenAlgo Automated Trading Bridge Project Overview I am looking for a developer to build a bridge between AmiBroker and OpenAlgo so that trading signals generated inside AmiBroker are automatically sent through OpenAlgo and executed on my broker account. The objective is to achieve fully automated trading, where once a strategy generates a signal, the system will automatically open, modify, or close positions without manual intervention. Workflow Requirement Trading Flow Strategy generates a signal in AmiBroker Signal is transmitted to OpenAlgo OpenAlgo sends the order to my broker Broker executes the order Execution status returns to the system The entire process should run automatically and reliably in real time. System Constraints All or...

I want a piece of wearable technology that creates a protective bubble just around my body, blocking or seriously attenuating incoming RF signals while also giving me the option to see what is trying to get through. In other words, it should both shield my own bio-signature from external probing and help me detect any active transmissions aimed at my immediate vicinity. The environment is highly personal—think a one-meter radius wherever I move—so the solution needs to travel with me rather than sit on a desk or in a wall. Comfort, size, and battery life therefore matter almost as much as raw shielding performance. What I imagine is a compact, self-contained module (belt clip, pendant, or similar form factor) that combines three core functions: 1. Real-time RF spectrum ...

I need a seasoned embedded engineer to design and implement a lean Time-Division Multiplexing protocol that funnels several high-speed ADC channels into a single, reliable UART stream. The end goal is clear: squeeze the maximum possible throughput out of the link without sacrificing data integrity. The work revolves around three core competencies—TDM protocol development, raw ADC data handling, and low-level UART communication—so fluency in each of these areas is essential. Our front-end hardware already produces digitised samples via a bespoke analog-to-digital conversion stage; your task is to move those samples efficiently over UART, interleaving them with tight framing, minimal overhead, and built-in error checking. Key deliverables • Well-documented C/C++ (or equi...

Quiero que revises y mejores mi circuito basado en un Xiao ESP32-C3 que controla una tira EL de 1,65 m mediante un inversor 3,7 V DC → 100 V AC, un sensor táctil TTP223 y un MOSFET lógico (AO3400, IRLZ44N o SI2303). Lo que más necesito es la mejora del circuito existente, poniendo el foco en la optimización de la eficiencia energética. Aunque sé que el mayor consumo proviene de la propia tira EL, quiero exprimir al máximo la batería Li-ion de 1 600 mAh para alargar la autonomía más allá de las 4 h actuales sin sacrificar brillo. Tareas concretas • Proponer el esquema más compacto posible, manteniendo componentes SMD de fácil adquisición. • Seleccionar el MOSFET l&oacut...

I am looking for an engineer or a small engineering team to help build a working prototype of a wearable smart ring that communicates with a thin wallet card device placed in a wallet. The purpose of the device is to prevent wallet loss by alerting the user when the wallet moves more than a short distance away from the ring. The system should provide two types of alerts: a vibration alert in the ring and an optional audio alert. The project goal is to create a fully working prototype that demonstrates the concept in real life. Experience with miniature electronics, wearable devices, Bluetooth communication, and prototype development is preferred.

I have a commercial IR-band Laser device with essentially two "Modes" - NORMAL and TRAINING, or restricted. Switching between the two can only be accomplished by accessing the Firmware via a proprietary 8-pin connection, for which I do not have a cable or interface. The candidate must either A) build a custom breakout to connect to the proprietary connector, or B) modify the OEM CONTROLLER pad and cable. Once the system is accessed, no custom coding, overwriting, or modification of the firmware will be required; the Candidiate need only identify the language, access the settings, and "flip the switch" between the two settings profiles. The hard part will be creating the connection. Something as simple as a POGO pin may be sufficient, but I am not qualified to say. T...

I have an Angular front-end that now needs secure Single Sign-On through Auth0. The only identity provider I want wired up at this stage is Google, and I only need to pull the user’s basic profile information once authentication succeeds. Here is what I’m expecting from you: • Configure Auth0 and my Angular project so a user can click “Sign in with Google,” be redirected to Google, grant consent, and land back in the app already authenticated. • Expose the returned ID token and profile object inside an Angular service so the rest of the app can subscribe to authentication state. • Add a simple route guard that blocks protected routes when the user is not logged in. • Include a clean logout flow that clears the session both locally and in ...

I’m building an automated live-play poker table and need the complete RFID hardware blueprint that will let software read every chip on the felt in real time. The table will hold well over 100 tagged chips at once, and I want reliable High-Frequency (13.56 MHz) reads at a maximum distance of about 10 cm from the antennas under the layout. Your task is purely on the hardware side: define an architecture that can see each chip as stacks move, bets slide, and pots grow, then pass clean data to the software team through a simple API or wired interface of your choice. Key expectations • Robust HF antenna array layout sized for a poker table, including multiplexing strategy to handle >100 simultaneous tags without collisions or dead zones. • Reader, controller, and MCU/FPG...

Für die Rolle gibt es die Möglichkeit, ...

I own a set of industrial-grade fans and want a clear picture of their current condition as quickly as possible. The job centres on a single spectrum vibration analysis that will reveal any bearing, alignment or balance issues. From that data I expect a concise machine health report and a short-term monitoring plan I can follow month by month. Deliverables I need from you: • One FFT spectrum analysis file (raw and processed) • A written health report explaining detected faults, severity and recommended fixes • A template or brief guide for monthly condition-monitoring reviews I can perform myself You are free to use the vibration tools you prefer (e.g., VibXpert, Emerson CSI, SKF Microlog, MATLAB) as long as your output is compatible with common formats such as CSV...
