Fabricante/bricolaje, educativo

Maker/DIY and educational products include resources for introductory self-study in the field of electronics such as user-assembled robotic kits and introductory texts, 3D printers and filaments for additive fabrication of mechanical parts, reference texts for industry professionals, and (while they last) a limited supply of vintage data books; tokens of an era fading quickly into irretrievable memory, when product information was transmitted in physical form.
