Overview
EasyEDA
EasyEDA is a web-based design suite that lets you create electronic schematics and printed circuit boards directly in your browser. You can move from a basic idea to a finished physical product without installing heavy software, as it integrates seamlessly with JLCPCB for manufacturing and LCSC for electronic components.
You can manage your entire workflow in one place, from drawing complex circuits to running SPICE simulations to verify your designs. It is built for everyone from individual hobbyists and students to professional electronic engineers who need a fast, collaborative environment to bring hardware projects to life quickly and efficiently.
QBlade
QBlade gives you a powerful, open-source environment to design and simulate wind turbines from the ground up. You can create custom airfoil data, integrate them into rotor blades, and perform complex aero-elastic simulations to see how your designs handle real-world conditions. It simplifies the transition from initial blade geometry to full-system performance testing within a single graphical interface.
You can use it for both horizontal and vertical axis wind turbines, making it a versatile choice for researchers, students, and engineers in the renewable energy sector. By providing tools for structural modal analysis and turbulent inflow generation, it helps you identify potential failure points and efficiency gains before moving to physical prototyping.
