     Mechanics and aviation are my Hobby, I work with Computers.

     The magic cube is the Rubik´s Cube. In this document there is a program that solve the magic cube always and a manual (in portuguese) where is showed mathematically the method of step 6. I invent this step 6. The step 6 solve the magic cube always. You can catch the cube in your hand to mess up the cube and the program solve the cube in your hand only follow the instructions of the program that you assemble the cube is easy and quick.

     I make the program in Delphi in October 2003. The program solve all solutions of magic cube. The manual show how I make the method of step 6 and teach how to use the program.

     The program was expanded in February 2025, I added the optimized Layer Method and demonstrate that it is possible to solve the 287 possible solutions using only a PLL and an auxiliary move! I also added the optimized Cross Method and demonstrate that it is possible to solve the 323 possible solutions using at most two algorithms!

     The program was expanded again in June 2025. I added all 61,920 solvable OLL and demonstrated that all possible solutions are solved with just one of the 57 OLL of the Fridrich Method. I found all the optimal solutions of the OLL. I demonstrated that the Top Layer of the Rubik's Cube is optimized naturally without you having to do anything. I wrote a paper where I demonstrate this mathematically.

     I discovered an optimization of the CFOP Method, which is widely used by Speed Cube. I demonstrated that all 61,920 OLL and 288 PLL are solved with just one of the CFOP algorithms; you never need two algorithms. If you don't recognize the pattern, I showed that you just need to rotate the top face to recognize it. The program shows all 62,208 possible combinations and the solution for each one using CFOP. The program shows all combinations grouped by the algorithm that generated them and displays an animation of all combinations. The program is suitable for both beginners and advanced users of the cube. The program works on Windows 32-bit or 64-bit and was finalized in 2025. I used Reverse Engineering to find all possible solutions at once! The program and documentation are in the files in my page in Portuguese.

     I know solve the Rubik´s Cube without using the program I did the program because I invented a method of solution.

Gearbox:

     This document teaches in details as to project and to build a gearbox. The gearbox can be placed in Airplanes, Ultralights, Trikes, Ships and Boats. The gearbox to increase the force of the engine. Most of the aeronautical engines and nautical engines use the gearbox. In this document there is the complete project to turn the engine Volkswagen 1600 equivalent to ROTAX 582. And a complete project to substitute ROTAX 912. I also show as placing automobile engines in boats.
     The document is in PDF format you can read him in any computer type. Use Acrobat Reader to read. The document is in portuguese there is not a english version.

     Tutorial about HP48 GX / HP48 G in Portuguese, the file is in PDF. The tutorial teach to program in HP.

     Compresser Winrar this compresser is very good it divide a large file in several little file, make self-extractor files and also use password to compress. All files this page were compressed with winrar.
