Microchips must be placed in the Non-Space Space Station to build the Ubertonic Dynabot (next-to-last blueprint) and get the "Mr. Roboto" achievement. To get them, build a Nebula Panda that converts junk parts into plasma beans. After gaining a large supply of plasma beans, either construct another Nebula Panda or use a Metamorph Carrot on the existing panda to create an Interdimensional Panda. It will convert sulfur crystals into microchips.
