I created a Raspberry Pi for my project. I had to use code to install things on my Pi. I also had to use code to sign in and sign out. I added LED's to the clear case (the image above shows Mr. Umekubo's lazercut case). I used 9v batteries to power the LED's. I also had to do some research on resistors. My final product was fantastic. I learned a lot while creating my Raspberry Pi. I bought a very cool keyboard and mouse, and used a standard asus 24 inch monitor. The Raspberry Pi model I used was a b+ model. I ran into a few problems while creating my Pi, one of them was sound. I tried to get my Pi to be able to play sound, but there were a few programs that were not compatible with the b+. I could not resolve this problem, but I resolved a different problem that occurred earlier on in the creating process. This problem was that I did not have an ethernet cord.
