I am looking for someone to develop hardware on my request, it will be simple projects as seen on you tube. I am interested to know hourly rates, if I provide the hardware and code they would just need to wire them up. Would be nice to have someone from India NCR.

I need a PCB designed specifically for a one-off project; it is not part of a commercial product line, so flexibility and creativity are welcome. The board will carry only analog circuitry—no digital sections—centred around operational amplifiers and a small signal-processing stage I will detail once we start. What I will supply: the schematic (PDF or KiCad), preferred footprints, and basic mechanical constraints. What I need from you: a clean, manufacturable layout with proper analog grounding practices, complete Gerber/ODB++ files, a reviewed BOM, and the original design file so I can revise it later if needed. Please aim for standard two-layer construction unless you advise otherwise for noise reasons. Acceptance will be based on: • DRC-clean files that import i...

The task is to design a compact PCB that drops straight into an SCX 1/32 car so it can run on a digital track. I want the board to read the track’s reed-sensor signal, let me assign any of 20 unique car IDs in firmware, and expose a surface-mount USB-C port on the edge for easy flashing once the body shell is back on. Size must stay close to the original analogue board footprint (about 24 × 18 mm, height under 6 mm) but I can adapt mounting holes or connector positions if you have a cleaner layout idea. Power comes from the standard track pickups (nominal 14–18 V DC), so include an efficient buck or LDO to feed the microcontroller and reed circuitry. I haven’t locked the MCU yet; pick anything small, inexpensive, and easy to program—ATmega, STM32, ESP32, or s...

I need a compact PCB developed for a one-off project that focuses purely on analog signal processing. The core task is to turn my hand-drawn schematic into a production-ready board, taking care of component selection, layout, and routing while keeping noise and crosstalk to a minimum. Here’s what I will hand over: • My rough schematic, functional block notes, and preferred connector footprints. • Target board dimensions and basic mechanical constraints. What I expect back: • A cleaned-up, fully annotated schematic (Altium, KiCad, or Eagle—use whichever you are fastest with). • Optimised PCB layout that respects analog best practices: short high-impedance traces, solid ground planes, and clearly separated power and signal paths. • Complete BOM with man...

I’ve drafted a single-layer board in Altium Designer and now need a seasoned set of eyes to run thorough simulations before I commit to building the first prototype. Your task is to import my project, verify the stack-up and component models, and perform all relevant electrical, thermal, and rule-check simulations available in Altium. Key goals • Confirm that signal integrity and power distribution meet design intent. • Flag any DRC or manufacturing issues early so I can correct them before fabrication. • Produce a concise simulation report summarizing the tests run, key plots or screenshots, and your recommendations. Deliverables 1. Updated Altium project files with all simulation settings preserved. 2. PDF or DOC report of findings and suggested fixes. ...

I need a compact, production-ready circuit that brings reliable wireless communication to a new consumer-electronics device. The work begins with schematic capture and component selection, moves through PCB layout, and finishes with ready-to-manufacture Gerbers, a complete BOM, and clear test guidelines. The radio link is the heart of the design, so careful RF layout, antenna matching, and regulatory-compliant power levels are essential. Bluetooth LE is my preferred protocol, though I am open to Wi-Fi or other 2.4 GHz solutions if you can demonstrate lower cost or better battery life without sacrificing performance. Please plan on: • Delivering editable design files in Altium, KiCad, or Eagle, plus PDFs for quick review • Calling out any critical components with long le...

I need a concise Python 3 script that will run on a Raspberry Pi 5 and do the following: • Watch a single GPIO input line for the HIGH digital signal coming from my Sony camera’s built-in AI output. • As soon as that digital signal is detected, drive a separate GPIO output that energises a small 5 V solenoid for five seconds, then automatically switch it off. • Debounce or otherwise ignore any further triggers until the five-second period is complete. The camera only provides a digital signal, so no protocol parsing is required—plain HIGH/LOW logic on the GPIO pin is all I need. The trigger itself must use the Pi’s native GPIO header rather than USB or networking. I haven’t fixed the exact GPIO numbers yet; feel free to suggest sensible default...

Abstract: Manufacturing-Ready 130nm CMOS Inverter Design The objective of this project is to design, verify, and prepare a standard CMOS inverter for fabrication using the SkyWater 130nm Open-Source PDK. Unlike theoretical projects, this work follows a complete "Silicon-to-GDS" flow. The process begins with Schematic Capture and Pre-Layout Simulation to establish electrical baselines. This is followed by Physical Layout, where the geometric structures of the NMOS and PMOS transistors are manually drawn according to strict foundry Design Rule Checks (DRC). The design is then validated through Layout vs. Schematic (LVS) to ensure physical-electrical equivalence. Finally, Parasitic Extraction (PEX) is performed for Post-Layout Simulation to account for real-world wire resistance and...

I need an engineer to take my concept for a high-voltage DC-DC converter and translate it into a complete, build-ready design that slots straight into a renewable-energy storage setup. The converter will accept 24 V DC at the input and deliver a regulated 165 V DC output. Efficiency, thermal management, and long-term reliability matter far more to me than squeezing every last cent out of the BOM, so component quality and sound topology choices come first. You will own the full electrical design flow—topology selection, key-component sizing, magnetics specification, control strategy, and all supporting calculations. I expect LTspice or an equivalent simulation environment to demonstrate stability, transient response, and efficiency before we move on to hardware. Once the numbers look...

I maintain a fleet of mission-critical electronic control boards that must run flawlessly around the clock. Although the hardware is operational, I want to squeeze every last drop of performance out of it and harden the supporting security stack. Your focus will be on two fronts that matter most right now: • Bench-testing the optocouplers and comparators on the boards, then fine-tuning or replacing any part that introduces noise, latency, or inconsistent thresholds. RS-485 paths are already stable, so your insights should drill straight into these analogue front-end components. • Re-creating my SOC lab scenarios, walking through the logs, alerts, and incident chains, and flagging bottlenecks or mis-tuned rules that slow response time. Packet captures, SIEM exports, and a fu...

I’m putting together a small interface that lets a 5 V logic line drive a 12 V DC mechanical relay while keeping the control electronics completely isolated from the field wiring. My plan is to repurpose an off-the-shelf two-channel relay module for the load side and pair it with a standard optocoupler breakout on the control side; you can choose whichever optocoupler best meets the brief as long as it fits the isolation goal. What I need from you is a concise, ready-to-build circuit design: • A clear schematic showing the 5 V input network, the optocoupler stage, any necessary current-limiting or pull-down components, fly-back diode protection for the 12 V coil, and the wiring to the relay board. • A bill of materials with exact part numbers so I can order everything imm...

I need a compact, production-ready PCB that reliably converts an EDP 1.2 video stream into a MIPI CSI-2 output so I can interface an existing embedded panel with a camera-centric SoC. The job is purely about signal conversion; no additional processing or scaling is required. The core of the work is selecting a proven EDP-to-CSI bridge IC, building a clean high-speed schematic around it, and laying out a board that respects all impedance and length-matching rules for both the EDP and CSI-2 differential pairs. Please keep the stack-up simple enough for standard 4-layer manufacturing while still meeting the 100 Ω/90 Ω requirements. To speed integration on my side I also need the power-tree designed, the necessary reference clocks routed, and all test points clearly labelled fo...
