The past week I went to an electronic articles store to buy some things.

1) A funduino joystick board with lcd screen Nokia 5110. Miniprotoboards and transistors. I want to use the transistors (2N2222) for make a binary calculator, and I read in wikipedia one can make a radio with less of 20 of them. The funduino is for try to make a portable video game. But I've been having some issues with the funduino. The box where I stored it fallen and it seems the Nokia screen is broken. Also the board is very dirty by back and have some bad or ugly weldings.

2) I was looking for a battery holder and motors for make a cardboard videogame and I found a set for make a robot chassis.

3) A kit for make Arduino projects. It have a shield compatible with Arduino Mega 2560 (it uses an ATmega2560 microcontroller chip). Other thing awesome, it comes with a 555 chip!!! If you want to know what is a 555, I recommend this video: https://www.youtube.com/watch?v=kRlSFm519Bo

Also, the kit comes with an ultrasonic sensor, it could be used for prevent to robots from collide with walls, with that tech one can make one of those cleaning robots. I learned it in the first semester of Electronics, we had to do an obstacle avoiding robot in an arduino online simulator as introduction to programming.

The kit also has a servomotor, I remember when I was a kid I saw on TV that servos are used for make animatronics, so it's cool have one now.

Besides go the electronics store. I bought a book on make ASCII games in C++. My main motivation were the programming class I received in the institute, in the second semester we learned object oriented programming basics in C++, but the course were very basic and I wanted to have a deep knowledge on the issue that could help me to do videogames.

A recommendation: Since like two years ago I've been working in a personal scientific project related with computing prime numbers and I'm starting to get results. There are many thing I could do thanks to math class in the institute, my ignorance in the field was stalling me. The thing is that studying these things I got curious about Cellular Automata and Complex Systems, among other Computer Science related things like the "P=NP?", and I wanted to learn about it in a non-superficial and non-expensive way, and I found a site called "Complexity Explorer" full of good courses: https://www.complexityexplorer.org

Finally, a cousin gifted to my a bad keyboard, the idea is to have fun examining it and trying to fix it.

Greetings!! And Happy New Year
