Design review of an industrial data-acquisition system — Stage 1 Safe Instrumentación (SFI), Bogotá, Colombia, designs modular data-acquisition hardware for geotechnical and structural instrumentation installed on bridges, hydroelectric plants and pipelines, at sites up to 4,000 m above sea level. SFI has a bench-validated four-board prototype: a main controller with cellular and sub-GHz radio, isolated RS-485 and native USB; two near-identical sensor front ends, each with its own MCU, for inclination and for a long temperature chain of up to 200 sensors on a shared bus; and a carrier board for a purchased vibrating-wire module with its own high-voltage protection chain. Part numbers are released under NDA. SFI has consolidated that work into a detailed design docume...

I have an existing advanced mechatronics prototype that was paused during development. I am looking for a senior hands-on engineer to review the current work, complete system integration, troubleshoot remaining issues, and bring the prototype to a stable, test-ready stage. The project combines: • Electromechanical components • High-current power electronics • STM32-based embedded control • Closed-loop/PID control • Multiple sensors • Battery-powered systems • Mechanical structure and custom hardware The main work includes: • Reviewing the existing design and implementation • Integrating electronics, firmware, sensors and mechanical systems • Debugging STM32 firmware and control loops • Tuning PID and system response • Troubles...

I’m developing a power bank whose two non-negotiable strengths are high capacity and true fast-charging performance. The unit will mainly top-up smartphones, so efficiency at the 5 V–20 V range matters more . I need a complete design package, looking on using Texas Instruments chips. The bank should expose 1 USB-A and 2 USB-C output ports (bidirectional)( 100W power output); USB-C Power Delivery and Qualcomm QC compatibility are welcome provided they don’t compromise overall capacity or ramp up BOM costs unreasonably. The board needs to have headers connectors as well. It will be connected to an Lilygo ESP32-S3 dev board for monitoring. Please base the electronics around readily available components, specify all ICs, and include thermal considerations, safety certifi...
