Geodesic Dome

A few weeks before Lisbon Maker Faire we were discussing about the projects we would present this year. We wanted to take there something big, something different, and then it came to us, what about a geodesic dome? As we were working on the SatNOGS project, which we will post soon, we came across the domes for protecting the antennas, basically a radome. It started out as a crazy idea, but eventually we thought it was simple enough for us to do it in a short amount of time, using 3D printed connectors and PVC pipes and clamps.

3D Printed DNA Lamp

This is a project I have made for the Instructables 3D Printing Contest. I was browsing online for some 3D designs when I found a DNA strand, and I noticed that when I rotated it, it created a weird hypnotising upwards and downwards effect, so I thought it would be cool to take advantage of that effect and use it on something, then came the idea of making a lamp. This will be a small summary, since  the full article can be found on Instructables. And STLs can be found on My Mini Factory.

Self Balancing Robot

The digital gyroscope is a very interesting component due its usage in modern systems such as smartphones or aircraft industries.

To participate on Lisbon Maker Faire 2014 we developed the Self Balancing Robot [SBR], which uses this amazing component, and helps to understand the principles behind the Segway vehicles.

Tesla Coil

Probably the most dangerous project we ever built in eLab, but still, also one of the funniest! The Tesla Coil, an air core electrical resonant transformer, invented by Nikola Tesla at the end of the XIX century, able to generate high voltages at high frequencies, resulting in electrical discharges just like small lightning.
