This week I did a cellphone dissection and learnt about all the different parts that make up a cellphone. The most interesting part of the phone, in my opinion, is the battery, which you can watch a short video about on this: website http://www.youtube.com/watch?v=HJrNCjVS0gk. Another really interesting part to a cellphone is the circuit board. Unlike the battery the circuit board is mostly made by robots, though the power a circuit board holds is amazing.
