Was thinking about purchasing a RaspberryPi just to learn about programming. I am just an old, disabled dude but still have the desire to learn things I don’t know. I used to build and program some of the first robots made in the US. I picked up linear programming and wrote many a program for simple 2 and 3 axis pick and place robots to 5 and 6 axis water jets cutting complex 3D parts. There are so many suppliers and option packages offered for the Raspberry Pi, I was just trying to figure out the best package to start with and the best supplier. I know I need the b board, a box, preloaded card, keyboard, book, and cables. Wondering about the Gertboard and Pi face to go along, and whatever else I need to get stated?
