I present you my portable desktop with which I can work with two screens wherever I go.
This project came out of my need. A guy asked me in a coworking where I bought it. As I saw that he was interested, I posted it on twitter, I got good feedback, ... one thing led to another and I decided that I would not manufacture the physical product, but I could sell the instructions.
Let me know what you think of the landingpage and what you think of the idea. You can make your own with very little money.
