Collaboration, Conflict & Consent

A two-day workshop with Eleanor Greenhalgh

_ Applying various methods of decision-making and evaluating the outcomes.
_ Practicing listening in teams of three [each having a specific role].
_ Playing group games, like counting to 20.
_ Creating a consensual artwork.

Module

Building a module with a guest tutor Dennis de Bel

Txx.uo manual [draft]

Txx.uo consolidates two contrasting radio frequency implementation modes: RFID reader scans the cards/objects containing RFID tags using radio waves and LCD screen displays a Q-code* [internationally established three-letter abbreviation used in radio communication].

*A particular Q-code denotes a question when it is followed by a question mark and references an answer [statement] when it's not:
QRU? : Have you anything for me?
QRU : I have nothing for you.

The RFID technology is used for object identification, authentication and security reasons, whereas Q-code is transmitted on a specific radio frequency by a radio operator and can be intercepted by anyone, who is tuned in to the same frequency.

This module converts the data received from a scanned card into a sound and binary code. This Binary signal is then transfigured into LED blinking and is also funneled to another module through an output channel. Top row of an LCD screen displays a specific question from the list of a Q-code, depending on a knob position and when receiving a signal from another module, a random Q-code answer is shown on the second row of the screen.
