Security, Electronics and Crazy projects

I always wanted to share my interests following my own way and other blog platforms can't provide me that. I can do the same using Wordpress, Google Sites or whatever but... It's not enought, I need freedom to create and share my knowledge and experiences in the way I want each time. Today, I am writting this introduction but maybe tomorrow I will prefer to create a secret konami code or stream a podcast. This is my digital house and It will follow my rules, expect anything, expect everything.

I am always willing to start new projects, these are the last ones. As you can see, the topics of the projects are always different. I love to discover new technologies and I tend to start projects related to my interests: Security, Privacy, 3D printing and electronics. You can look here to see all the projects.
