Interactive Murals with Electric Paint and Arduino
The workshop started with the basic principles of electronics; What is an LED? What are electronics? What is conductivity? What is resistance? They then shared examples that they made themselves, using graphite as a conductive material. They made light sensitive stickers through the use of transistors and even made an oscillator that translated variations in resistance into an audio.
The group learned the basic principles of programming, first in Scratch and later in Arduino. They also learned to use commercial electronic boards, such as OTOTO, Makey-Makey and Arduino, and then the Bare Conductive Touch Board.
All programming and circuits seen were made with soft conductive materials, such as copper tape and Electric Paint.
Although these old lacustrine zones still conserve chinamperas zones and wetlands, problems like the lack of water supply and the contamination of drinkable water affect the population of this region.
The line in blue joins all those small microhistories, to visualise a map of Tláhuac, because, for the people there, water is a social and historical connector; a common denominator that is present and unites all that live there.
When people talk about the history of technology, they also talk about the history of humanity. An example of this can be seen in all the technological devices we use today; what would computers be like today if the wheel had never been invented? There is, also, the knowledge that is passed from generation to generation. This mural presents a series of everyday objects that, in different historical times, have created what each of us is today.
Faro Milpa Alta
Milpa Alta is one of the rural areas of the city, which holds some urban characteristics. People living there believe in the importance of preserving day to day traditions, like for example, the treatment of the milpas, the morphology of a teporingo, or the legend of Juan Carnero, among others; because part of this knowledge is now unknown to some inhabitants of the Mexico City.
Faro Indios Verdes
This interactive mural uses a tree to symbolise the history of the Faro. They relate to certain elements of the flora and fauna native to this region. In addition to the historical elements of the construction of the Faro, they also added shoes, to allude to the old factory on which the Faro was built. In the treetop are stories of the current community, symbolising a growing community.
The figure of the market on wheels plays a crucial role in the history of Mexico City. In Faro de Oriente, the team decided to portray a series of objects that refer to the tianguis of “El Salado”, not only because of its importance in their production, but also because of the symbolic strength of all the goods that arrive there. They’re interested in showing those technological objects that have been forgotten, that have lost their common use, that have passed through many hands, and that now seem as if they were a sample of fossils. The piece alludes to older technology that has been forgotten, but has inspired many other products.
