About this site

These pages document my experiments in the exciting world of open hardware and physical computing.  Just as open software has changed our world open hardware is allowing many people to learn, experiment and create electronics projects.  Hopefully these projects will inspire others to experiment also.  I live in Costa Rica and will be sharing tips and tricks that are relevant locally.

A major challenge for inventors in Costa Rica is acquiring microcontrollers and other specialized components.  One of my projects is a local online store: CRCibernética.com.  We have been maintaining U.S. list prices in Costa Rica.  Happy hacking!  I can be contacted for questions of comments at:
