tech nerd and tech savvies assemble

guys my parents don't allow me to learn tech much and i am totally clueless about even the basic thing so here's the thing i am having a competition at school and my friends roasted me in front of everyone that how i don't know tech and a lot of hurtful things i am trying not to remember they said it in front of everyone i wanna win this competition the theme is something innovative like something that a lot of people wont know most moving i wanna at least try to win this competition but as i said i don't know anything this will be hard as there is no stuff at my house like 3d printer and all so i was hoping if you are willing to help me a little by suggesting few books some basic things to get and please keep in mind that most things aren't available here as i live somewhere far away

please suggest ideas with that in mind if you dont wanna help it up to you , mostly in my heart i do hope yall will help me with this world already so overtaken by ai there are people i know for sure trying to help (i am 12 years old btw)
