BI0FILM.NET

Independent and distributed communication networks are at the core of the self-organized communities. Based on the idea of biological peer to peer networks, that explore how microorganisms like bacteria communicate and collectively act, we have built a human biofilm-like connectivity enhancer. “Biofilm.net” is an umbrella antenna that hacks an everyday use umbrella, turning it into a parabolic WIFI antenna that can extend the signal range for a mobile phone to join a network.

 

Besides covering, hiding and protecting the user, Biofilm.net helps them communicate. Depending on the adaptation, the umbrella can act as a repeater, as a complementary part of a "cantenna" or just as an extender of a WIFI antenna for a mobile phone or a computer.

1.

Dismount the plastic cover of the umbrella and get one of the triangles as a cutting pattern.  Keep all the plastic components. 

2.

Cut the metal mesh using the pattern. As many as the umbrella sides. 

3.

Sew the cutting pattern back onto the plastic cover and then sew the metal mesh to it. Mount it back in the structure.

4.

Replace the stick for a plastic one and cut the new stick to the focal length of the parabolic shape. How to calculate the focal length here

5.

Add a nylon screw to the end of the stick to finish the upper part of the umbrella.
