Me

hello i am pablopeza

this is my blog

Based in A Coruña, works at Innogando S.L., and has been quietly stockpiling GitHub repos: a one-hand bottle opener, a 3D printer parts library literally named “Pezas_Printer,” sumo robots, line followers, and enough H-bridge motor drivers to open a shop.

Also part of BricoLabs , an A Coruña hackerspace/makerspace where a bunch of CAD, electronics and 3D-printing enthusiasts meet weekly at the Domus.
