I don't know if I posted on the right forum but I know I'm on the right site. I'm planning to create my first homemade rocket that can fly maybe hundreds of feet or less then it will parachute down after peacefully. I'm not an engineer but if you willing to help me, I would feel how to become one. By the way, I'm a computer science student majoring in graphics development. Could you give me some instruction or maybe a site that teaches one so I know what and where to start. Is it dangerous to build one? Do I need a permit to fire it up? Additional, if you know how to program on a homemade small chip hardware to open a small parachute on a box, it would be great if you teach me how. This one is so great and I want to build one.
