An ion thruster is a type of electrical propulsion system used for spacecraft propulsion capable of creating thrust by accelerating ions. Back in June 2015, I remember seeing this demonstration for the first time on Makezine, by Alexander Reifsnyder. I thought it was amazing for its scientific value and at the same time quite easy to build, so me and Hugo thought we could make our own version of it, using 3D printed parts.
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.

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.
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.
With Lisbon Maker Faire 2015 almost here, we feel like now it’s the perfect time to remember last year’s event!
Maker Faire is the greatest show and tell in the world! Originally created by Maker Media , it’s an event to celebrate arts, crafts, engineering and science projects associated with the Do It Yourself (DIY) movement where the main focus is the sharing of knowledge, experiences and ideas.
