Our two-turbine, 2 × 250 kW hydroelectric station is now in the construction phase and the control panels are ready for code. I need a complete PLC program built around a Delta CPU of AS series. The logic must: • Start, stop, and protect each Francis turbine, including speed regulation and emergency shutdown routines. • Modulate inlet gates to manage water flow while maintaining set-point head and optimising efficiency. • Continuously monitor generator voltage, current, frequency and bearing temperatures, triggering alarms and trips when limits are breached. An accompanying HMI (Delta DOP or compatible) with clear status pages, trending, and manual-override screens is expected. I will supply P&IDs, I/O lists, and functional descriptions—your task i...

We are looking for an engineer team which has a good PCB design skill with motor driver knowledge and experience with good programming skill. This project is to upgrade our current PCB(Old prototype: having some issues) to update version. We will make one prototype PCB to test. This machine has the following system: 1x main CPU (GD32F450IGH6) 1x AC motor inverter (RS485) Command input 1x sensor Up to 5x stepping motor ( synchronized, need fast movement)　 Up to 5x sensor 1 x DC motor 1 x sensor 1 x SBC( RPI) need to connect to main CPU ( need to have fast communication ) 3 x stepping motor 3 x sensors 1 x DC brushless (small ) 2 x stepping motor 3 x COM to other device Ethernet We will send the current prototype PCB info induvidually when we decide to proceed. Current prototype ...

I’m adding a UART-based audio path to the Android build of my product and now need the equalizer layer. The goal is strictly audio processing: the app (or library) must intercept the UART audio stream, apply EQ and other effects in real time, then pass the processed signal back to the system. Core requirements • Equalization controls – band-based sliders plus overall gain. • Optional audio effects such as bass-boost or reverb that can be toggled on/off. • A dual-preset system: ship with a set of predefined curves (Rock, Pop, Classical, etc.) while also giving users full freedom to create and save their own custom EQ profiles. Please keep the code clean, documented, and compatible with recent Android SDK levels. I will test with both physical hardware over...

I need a production-ready PCB for an industrial ranging device that will be integrated into larger automation machinery on our factory floor. The board has to combine three core capabilities: robust signal processing of the sensor data, reliable high-power outputs to drive downstream actuators, and on-board wireless communication for status reporting and firmware updates. The footprint must stay within 80 mm × 60 mm, operate from a 24 V DC rail, and meet industrial EMC/EMI standards (EN 61000 family). A multilayer stack-up with controlled impedance traces for the RF section is expected, along with generous creepage/clearance on all high-current paths. Deliverables • Schematic (Altium or KiCad) • Fully routed Gerber/ODB++ files ready for fabrication • Annotated ...

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...

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...
