Extensive collection of vintage pocket calculators

"1970s Vintage desktop and pocket calculators listed by company (131 identified brands, 613 calculators). ..., it is crazy to think that in many of these calculators you have a chip that is bigger in size than one of the Intel Core Family processors."

Fabrication of organic transistors through printing

"Another important characteristic of organic transistors is the simplicity of the method used to produce them. Inorganic transistors require massive vacuum systems and complex manufacturing processes. However, most organic materials can be dissolved in organic solvents to create 'inks' that can be used to create circuits simply by printing them under normal atmospheric conditions. Printing technology can also be readily adapted to the production of flexible substrates and large substrates. With the methods used to manufacture conventional inorganic transistors, only a few percent of the materials are actually used. Printing is far more efficient, and by optimizing the method it is possible to achieve usage rates as high as 90%. For this reason, this manufacturing method is also attractive from an environmental perspective. Sony is currently conducting research into the fabrication of organic transistors through printing."
