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).
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. If you’re not into DIY, you can get one on Tindie.
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.
Another eLab’s workshop was organized last month, November 28th. On this workshop, participants were given the opportunity of learning to use the Arduino, a single board open source platform with a microcontroller, very famous for its flexibility and for being easy to use by artists and beginners.
eLab will organize a new workshop about “Electronic instrumentation for beginners based on Arduino” in November 28th at 5.30 pm.
