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...
