The book explains how to use your iphone to make all the cool projects
of metal detector, tricorder (not much into star trek to appreciate its
need), bluetooth low energy shield. This process helped me understand my
iphone and its innards better. The author had a good consideration
about his audience being from a software or hardware background but not
both and maintained that bridge connection to make the readers feel at
ease. That said the book still requires a good amount of coding skill.
since the book is about very specific projects, it caters to a very
narrow niche of makers. The book would have done with a general expanse
of applications and less detail.
