My entrepreneurial idea is to produce a machine that reads your brain waves and transmits those brain waves into physical activity, or images onto a tablet computer. If i were to will it, I can paint a whole landscape with my brain or take lecture notes with my brain onto a tablet.

In order for my idea to work, there must be an actual tablet that can read my brain waves.
However, the human brain is an extremely complex system. To play a game with complex algorithms, the computer reading the game must be very powerful. Following that logic, the machine that translates your brainwaves onto a tablet must also have lots of power.

A powerful motherboard, processor, RAM, hard drive, and graphics card are needed for this tablet. The motherboard is the main circuit unit so it needs to be strong to match everything else other the whole system will suffer. The process also needs to be strong because it's like the brain of the whole computer. Every single action the tablet takes will have to go through the processor. A good processor makes a fast computer. You might need a quad core processor so the tablet won't lag while you're creating an image on it. Furthermore, the arithmetic logic unit needs to also be powerful.

RAM is necessary because while the machine is reading your brain waves, it also needs to write down or copy down the information it's reading and turn it into images for you. Just reading the brainwaves will use up a lot of power, so lots of RAM is required. More RAM equals a faster computer. In addition, lots of hard drive space is needed too to store the images your brain makes. In the future, Solid state drives should make reading speed faster also so the overall performance will improve. A good graphics card is very important because you want the images you create to look like the ones you envision. If your brain 'sees' 3 calculus equations in class, but because your graphics card sucks, then your equations might be mixed up because it's not reading the images clearly. We're in an age of HD now. Everything needs to be clear and crisp.

Maybe a sound card will be required too but a powerful one isn't really necessary.
