Open fab project – Light Saber

Open fab project – Light Saber

Paulin and Côme, 2 pupils in 9th grade at the French International School came to Atelier Fablab for one week internship. The objective of this internship was to spend one week in a company to discover a profession. They decided to discover the universe of Fablabs! They came along with an ambitious project: design and build their own lightsaber.

It was the occasion for Paulin and Côme to discover different design and prototyping techniques.Their project involving electronics, 3D modelling and 3D printing has been developed in total autonomy by the two young makers. 

First, they designed the numerical model of the cross guard and pommel using Sketchup CAD modelling software.

During the design phase, the following specifications had to be considered:

– The cross guard should be big enough to include the Arduino* microcontroller and electronic components.

– The cross guard had to be resistant enough to bear force.

– The pommel should be big enough to include the battery.

*Arduino : Arduino is an electronics prototyping platform that helps you control real-world objects.

The young makers used standard copper tube for the grip. The length was adjusted with a tube cutter.

The next step was coding and assembling  the electronic components using a breadboard prototyping platform with the objective of validating the electronic design before final assembling.

The final step consisted in  assembling the light tube to the cross guard. 

It took Paulin and Côme, one week of work to create the object of their dream and realize that you can make (almost 🙂 everything in a Fabab.

“This week at the FabLab, I learned: to model an object in 3D, to print it with a 3D printer, to weld electric components, to code an Arduino board and to realize the mounting of the card.

Thanks to the FabLab because with their help I could realize my dream by creating my lightsaber. It was a great experience.”
