After buying a new electrical appliance / piece of equipment, removing the cover, making a note of all the part numbers of all the major IC's and looking up the datasheets? Most of the time I have been lucky in finding data on most devices, but there have been one or two instances where I cant find much information at all. It is very interesting to read up on some of the information especially on SoC's I have only found one detailed data sheet on an SoC though However things like memory, codecs and supporting devices are not hard to find information on.
