I need to push NFC performance well beyond the usual tap-to-pay distance. The task is to design a tuned 13.56 MHz antenna, compatible with common NFC controller ICs, that can reliably achieve a read/write range greater than 30 cm while staying within regulatory field-strength limits. To succeed you should be comfortable with loop or spiral coil design, impedance matching, and low-frequency RF simulation. A solid grasp of ISO/IEC 14443 or 15693 coupling mechanics is essential because I want to keep the front-end electronics standard and let the antenna do the heavy lifting. Deliverables • Optimised antenna geometry (model, calculations, and rationale) • Schematic and PCB layout files (KiCad or Altium) • Complete manufacturing package: Gerbers, drill files, and BOM &...

I am developing a complete FPGA-based 5G NR Low-PHY platform for an O-RAN 7.2x radio architecture. The objective is to design, implement, integrate, optimize, and validate the complete real-time digital signal-processing chain rather than isolated FPGA blocks. The scope covers O-RAN 7.2x/eCPRI fronthaul processing, IQ compression/decompression, FFT/IFFT and cyclic-prefix processing, resource and antenna mapping, 2×2 and 4×4 MIMO, precoding and digital beamforming, DUC/DDC, channelization, interpolation/decimation, digital filtering, CFR, DPD, calibration, gain/phase correction, multi-carrier processing, timing/synchronization, and high-speed ADC/DAC interfaces. The engineer will be responsible for FPGA architecture, RTL/HLS/IP implementation, block integration, clock-domain a...

I’m looking to wire together a fully automated flow where TradingView fires the signal and Delta Exchange carries out the trade—no manual clicks in between. Here is the current framework I already follow: • Indicators: 200-EMA is the backbone, combined with one additional indicators (EMA based) that I’ll share once we start. • Signal logic: a trade is triggered whenever my chosen indicators cross the 200-EMA. • Trade type: Sell Options only—no futures or spot orders. What I need from you is a Pine Script strategy that produces the exact sell-option alerts and a middleware (webhook listener, small server script, or similar) that catches those TradingView alerts and pushes the corresponding order to Delta Exchange through their REST API. Po...

Hi there, I am looking for an experienced PCB design engineer to lay out a small, high-power LED strobe controller board and prepare the manufacturing files for JLCPCB Economic PCBA (surface-mount assembly) [1.2]. The design is completely finalized conceptually, and I have attached the Engineering Requirements Document (ERD) and the Final Schematic Pinout Map below to serve as your definitive layout blueprint. Project Deliverables Required: Complete schematic and 2-layer PCB layout using EasyEDA (preferred) Verified BOM (.csv) matched to standard, low-cost components from the JLCPCB parts catalog. Formatted component placement centroid file (). Production-ready Gerber Fabrication Bundle (.zip) [1.2]. Core Structural Criteria: Form Factor:...

Ich brauche eine kompakte Ladeelektronik für eine selbst gedruckte iPad-Halterung, die künftig in kleiner Serie gefertigt werden soll. Worum es geht • Grüne LED soll anzeigen, dass an der KFZ-Versorgungsleitung stabile 12 V anliegen. • Zweite LED signalisiert, dass das iPad tatsächlich lädt. • Es genügt die reine Basis-Elektronik; ein externes Gehäuse ist nicht nötig, da die Halterung bereits eine passgenaue Aussparung besitzt (Muster liefere ich). • Standard-LEDs sind vollkommen ausreichend. • Ein integrierter Kurzschlussschutz und Sicherung ist zwingend erforderlich, weitere Zusatzfunktionen werden gegebenenfalls besprochen. Liefererwartung 1. Schaltplan und durchdachte Bauteilauswahl (BOM) mit mar...

I need a compact, carrier-grade RF-over-Fiber module engineered specifically for telecommunications links. The goal is to move an RF signal from a remote antenna site to my baseband equipment with the lowest possible noise, excellent linearity, and rock-solid gain flatness across the target band we will finalise together during kickoff. Scope of work • Translate my high-level link budget into a full electrical-optical-electrical design, covering the laser driver, optical modulator, photodiode front-end, biasing, RF amplification, and control electronics. • Produce complete schematics, PCB stack-ups, Gerber files, and a BOM with ordering part numbers that are actually in stock. • Simulate performance (ADS, Keysight PathWave, or similar) and document noise figure, IP3, ...

I need a complete control-board design for a single-phase, Level 2 AC EVSE that can deliver up to 7.5 kW (6 A – 32 A adjustable on a 220-240 V supply). The job covers the full schematic capture, PCB layout and a production-ready BOM. Key points you’ll be working to: • Detailed design with BOM is required; I will handle manufacturing separately once the files are ready. • Through-hole components only, so footprint selection and spacing must respect that choice. • Please keep to standard board dimensions so the enclosure work stays simple. Functionally, the board must handle: – Pilot signal generation and sensing in line with IEC 61851. – Contactor or relay drive for load switching. – Temperature and ground-fault monitoring circuits. &...
