Electrical Scope of Work: Power Requirements and Engineering Studies for Aluminum Extrusion Facility number 2. Scope of Electrical Engineering Services The following electrical engineering services will be provided for the aluminum extrusion line installation: 1. Single-Line Diagram (SLD): Development of a comprehensive single-line diagram illustrating the complete electrical distribution system, including utility service entrance, transformers, main switchgear, distribution panels, motor control centers (MCCs), and all major loads. 2. Fault Study (Short-Circuit Analysis): Detailed short-circuit fault current calculations to determine available fault currents at all key points in the system, equipment ratings, and protective device coordination. 3. Arc Flash Study: Full arc fla...

I need a compact, low-noise analog front end for a multi-lead ECG built around the Texas Instruments ADS1298. The goal is a fully validated schematic and PCB layout that can capture clean ECG signals, digitise them through the ADS1298, and present the data via an SPI interface for a downstream MCU. Key points of the job • Core converter: ADS1298 integrated correctly with its internal PGAs, reference, and bias generation. • Signal chain: front-end instrumentation amplifiers, right-leg drive, antialias and mains-rejection filtering sized to meet IEC 60601 ECG bandwidth/noise limits. • Power: dual-supply or single-supply rail architecture with proper isolation and low-drop regulators. • Safety & compliance: pay attention to patient-isolation clearances and leaka...

I need a precise, low-resistance solder joint made on the battery leads of my drone. The task is straightforward: take the existing electrical wire coming from the battery pack and solder it securely to the designated battery connection pads/connector on the airframe. A clean, shiny joint with proper strain relief is crucial so the connection can handle both current spikes and the vibrations that come with flight. Bring whatever tools you feel most confident with—a temperature-controlled iron, fine rosin flux, decent solder (60/40 or lead-free is fine if you’re comfortable), and heat-shrink tubing for insulation. Once the joint is complete, I’ll do a quick continuity and voltage drop test; as long as it passes and looks solid, the job is done. If this is something you c...

I need a complete electrical and mechanical design for a Framework Laptop expansion card built around the RP235xA microcontroller in the 30-GPIO QFN-60 package. My top priority is that everything fits perfectly inside the standard expansion-card envelope defined in Framework’s official repository (). Key requirements you must hit • Use the RP2350 and expose all USB-C power and signal constraints exactly as the Framework reference dictates. • Keep the card flush: no part of the PCB, component or connector may project past the official boundary. • Place two tactile switches (reset and boot) plus one RGB LED (I’m thinking WS2812 or equivalent) and one status LED on the underside so they are visible and accessible when the card is plugged into the laptop. ...

I need a complete hardware design for a piece of manufacturing-grade industrial equipment. The scope covers both the mechanical layout and the integrated electronics that will drive and monitor the unit; no hydraulic systems are involved. You’ll take the concept from requirements capture through to production-ready documentation, combining robust mechanical engineering (think SolidWorks or Creo for 3-D modelling, tolerance analysis, enclosure design, safety guarding) with a reliable electronic control system (schematic and PCB layout in Altium or KiCad, component selection, firmware interface notes). Deliverables • 3-D CAD assemblies and detailed part drawings • Electronic schematics, PCB Gerber files, and annotated BOM • Integrated system diagram showing how t...

I need a compact, reliable AC solid-state relay designed specifically for driving pump loads. The control side will accept 3–32 V DC, while the load side must safely switch 24–380 V AC at a continuous 25 A. Core expectations • Status indication via a front-panel LED • Full opto-isolation between control and load • Zero-cross switching is preferred to minimise inrush, but I will consider a non-zero-cross solution if it offers clear advantages for motor-driven pumps. • The housing should be compatible with a standard heat-sink footprint, and I am open to either DIN-rail or panel mounting depending on what your thermal calculations show to be most practical. Deliverables 1. Full schematic with component values and reference designators 2. PCB ...

Project Overview We are seeking an experienced Embedded Hardware & Firmware Engineer with strong expertise in power electronics to design and develop a complete hardware and firmware solution for a variable-frequency, variable-voltage AC power supply.

Technical Requirements Input * DC Input Voltage: 120VDC to 150VDC Output * Output Frequency: 0 to 100 Hz (programmable) * Output Voltage: 20VAC to 100VAC RMS (programmable) * Stable output regulation across operating range Control Interface * SPI interface for: * Frequency adjustment * Output voltage/amplitude adjustment * Status and fault monitoring (preferred) Scope of Work Hardware ...

I have a small home-automation module that needs a reliable touch interface, so the task is to engineer a 5 V circuit around the TTP223 that cleanly switches between high and low digital levels whenever it is touched. Precision in sensitivity and long-term stability matter more to me than squeezing out the very last microamp, yet the design should still sit comfortably in standby without wasting power. Key expectations • The sensor must tolerate normal household electrical noise without false triggering. • Output logic levels must be directly MCU-friendly (TTL/CMOS, active-high preferred). • Component count should stay minimal; surface-mount parts are fine. • Any necessary debounce or filtering should happen in hardware rather than firmware. Deliverables 1. ...
