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 need a double-layer, signal-processing board laid out in Altium Designer and prepared for fabrication at JLCPCB. The finished board will fit inside a 15 cm × 15 cm envelope, so component placement, routing, and keep-outs should respect that medium-size constraint. Deliverables I expect: • Complete Altium project with schematics and PCB layout • Optimised Gerber, drill, and pick-and-place files matched to JLCPCB’s specs • BOM with manufacturer part numbers and assembly notes I will review the design by importing the files directly into Altium and running JLCPCB’s online DFM check; the job is complete once the files upload without errors and the board passes ERC/DRC.

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...

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...

We are developing a carwash kiosk control board that will work together with our Paymore TPOS device, and we are looking for an experienced embedded hardware designer to design a production-ready PCB. This is a real commercial product that will go into mass production, therefore the design must be industrial-grade and manufacturable. The board will control a P10 LED panel (HUB75) that runs continuously 24/7, displaying countdown timers and simple messages. The system must also include Pulse+ and Pulse− inputs that can operate either as dry contact inputs or opto-isolated inputs, counting pulses and triggering system actions. Based on the detected pulses, the board must activate one of 10 independent output channels that can drive 5V or 24V signals for a defined period and then autom...

I need five separate input-output matching networks for the MACOM CGHV270305, one for each of the following RF bands: • 30–200 MHz • 200–600 MHz • 600 MHz–1.8 GHz • 1.8GHz–4 GHz • 4GHz–6 GHz For every band the network must deliver at least 30 W across the full span while maintaining solid, stable gain. I will verify this from the final performance plots, so please present both power-output and gain data together in clear scatter-plot format. Alongside the simulation results I need production-ready DXF files of the matching PCB layouts. Keep the drawings aligned with recognised industry standards so they can move straight into fabrication without extra re-work. Deliverables 1. S-parameter models (touchstone) and any suppor...

Project Title: Miniature Piezo Preamp PCB (10mm) – Reverse Engineer & Redesign Project Overview I am developing a professional leak detection microphone used for plumbing diagnostics. The system uses a piezoelectric sensor to detect vibration and sound from water leaks inside pipes. I already have a working preamp circuit, but the PCB is too large for my application. I need an experienced electronics engineer to analyze the existing design and redesign it into a much smaller PCB. The new design must maintain similar electrical performance but reduce the physical size so it can be mounted directly on the piezo sensor and permanently sealed with epoxy resin inside a capsule. Primary Objectives 1. Analyze or replicate the functionality of my existing piezo preamp. 2. Redesign ...

I need a seasoned LUA developer who also speaks the language of audio engineering to extend the processing palette on Symetrix, RANE and Allen & Heath DSP platforms. The work sits squarely inside each manufacturer’s SDK, so the GUI framework is already included what we need from you is efficient signal-flow code that drops straight into the existing interface. Primary tasks • Write well-commented LUA modules for DSP • Add pitch and general frequency-management routines that can be chained with, or operate independently of, the above effects. • Optimise code and supply test files that we can provide feedback on Further details on request..

We need an electronics engineer to implement a PCB design based on an existing schematic for a renewable energy monitoring project. The system measures electrical parameters from multiple sources including a solar panel, wind turbine, battery, and inverter output. The schematic already exists in PDF format and includes components such as Arduino Nano Every, MCP3903 ADC, ADS1115, WCS1600 current sensors, and HC-12 communication module. The task is mainly to follow the existing schematic, verify the design, and create a manufacturable PCB layout.

I am ready to move from concept to production on a 55-Zoll LCD Digital-Signage-Screen and need an experienced hardware developer to guide the full electronics side. The panel size is fixed at 55", and my preferred control solution is a Huidu motherboard, Android 13, 14; if you have a strong case for an equivalent European board, we can discuss it— The job covers everything between the raw panel and a turnkey prototype: selecting the exact Huidu mainboard model, designing or adapting the logic board, defining all I/O (HDMI, USB, Ethernet, Wi-Fi, audio, power input, service port), creating schematics and PCB layout, and supplying a production-ready BOM with component alternatives that are immediately sourceable in Europe. I will also need the firmware flashed, tested, and demonstr...

I need help turning three off-the-shelf modules now sitting in my glasses prototype—a USB 2.0 hub, a USB audio codec (mic plus stereo out) and a dual-channel Class-D amplifier—into one long, narrow board that can slide inside the temple arm. The space I have measured is roughly 80 mm × 15 mm, so the layout has to be linear rather than squarish, with components placed to keep the height profile as low as practical. The board will run exclusively from the host’s 5 V USB rail; no batteries or additional supplies are planned. Because this is for voice prompts and basic media playback, a standard-grade codec is fine—I’m not chasing audiophile specs, just dependable microphone input and clean stereo output that won’t hiss or pop when the amp is idle. A...
