About

MaxwellsDemon

Features
Read full description

You can learn the essence of statistical thermodynamics. Through simulation of gas molecular motion, you can intuitively understand basic concepts such as molecular kinetic energy, temperature, and entropy. Prepare a hot gas and a cold gas separated by a wall. Remove the wall and mix the two gases. Then, place the wall, which is covered with Maxwell's demon, in the center of the container, again dividing the container in two. What will happen?

About

PIDSimLab

Read full description

PIDSimLab โ€” PID Simulator PIDSimLab is a lightweight PID simulator built to help you understand and practice PID tuning. Adjust Kp, Ki, and Kd and instantly see how the system responds on a live step-response chart. Save traces and compare runs to find stable, fast, and smooth settings. Key features PID tuning: Edit Kp / Ki / Kd and observe the response immediately Time duration control: Adjust the simulation duration to observe system behavior across different time scales Start / Stop control: Run and pause simulations with a tap Test profiles: Try preset scenarios to speed up experimentation Real-time charts: Visualize the response curve as it evolves Save traces: Store runs and compare results across different settings Simple UI: Designed for quick learning and practical use PIDSimLab is useful for students, hobbyists, and engineers who want a clean, focused environment for exploring PID behavior.
