Tools engine is a platform where i have made many tools like 3d solar system, projectile motion simulator and etc. It is completely open source and can be customized by the user.

Below here is a list of different tools present here:

1. 3D Solar System - A 3D simulator that simulates the solar system.Fun part: We can customize orbital speed too.
2. BMI Calculator - A simple BMI calculator where we can calculate if we are underweight, overweight or normal.
3. Wave Simulator - A simulator where we can simulate wave's, we can observe its heatmap, customize amplitude and wavelength too
4. Number Systems Converter - A Number System converter where we can input a number and we can get that number in different number systems.
5. Geometry Calculator - A calculator where we can do geometric calculations like finding area, perimeter.
6. 4 band resistor's Resistance counter - A resistance counter where we can count a resistor's resistance(4 band)
7. Data Visualizer - A tool that can be used to make charts of data's. It is very useful for observing datas.
8. Projectile Motion Simulator - A simulator where we can simulate and observe projectile motion.Here, we can customize the value of factors too.
9. Collisions Simulator - A 2d collisions simulator where we can observe the collision between two objects where we can customize its size,mass etc.
10. Pendulum Simulator - A simulator of pendulum where we can observe it and here, we can customize rod length, mass and etc.
11. Charges Simulator - A simulator where we can simulate proton and electron and watch its magnetic field.
12. Probability Graph Visualizer - A math tool where we can visualize the probability.It gives expressions too.
