Maker Faire 2015 Summary

After the huge success that was Lisbon Mini Maker Faire 2014 with over 9000 visitors, here we are again at Maker Faire 2015, which as you’d expect, surpassed all expectations from the previous one with around 14000 visitors.

This year there were about 120 projects from different areas, from 3D printing with printers developed by the makers themselves, to robotics, solar powered vehicles, CNC’s, customizable skate boards, a low cost Geodome, an optic intercommunicator, a vintage videogame museum, countless garage projects, etc. Here I’ll do a small summary mainly focused on the projects representing Algarve, which were able to get 1 best in class of science prize and 5 maker of merit awards … Congrats to you all!

Playing with nixies: Yet another Nixie Clock

Nixie tubes are electronic devices for displaying numerals or other information, such symbols or letters. They work under the  principle called Glow Discharge. Basically, they are tubes filled with a low-pressure mix of gasses and two (or more) metal electrodes. When a voltage is applied to two of this electrodes, and such voltage exceeds a certain value called the striking voltage, the gas in the tube ionizes, becoming a plasma, and begins conducting electricity, causing it to glow with a colored light (depending on the gas filling the tube, for tubes with neon this color is red-orange).
