- Morse Attacks!

- We Want Morse (out)

- Morse Revisited (out)

- Transceive! (out)

- Plateaux Mobiles (out)

Environment

HeK on GoogleMaps

Workshop A

Concept

Extracting common environment data via self-built device which encode environment data such as temperature, vibration, brightness, frequency of on/off event to morse-code of participant defined message, participant can read, listen and send our environment as morse code instantly thru walkie-talkie frequency to the installation.

Rather than mere a passive listener, the device also reacts to certain morse code messages that could be defined by the participant with simple programming with ATtiny chip.

To-Dev

audio signal transmission
communication protocol allows all devices to establised bi-direction communication to exchange data.

Requirement from paticipant

Nope, perhaps an OpenMind,
but welcome to bring a laptop if one likes to dig in their own ATtiny code & web interaction

DIY Device

>> Dev-Page

Sender :

microcontroller (ATtiny)
walki talki
various sensor (temperature, piezo, light resistor, contact pad)
PCB board/wire

Receiver :

microcontroller (ATtiny)
small LCD Display
walki talki
PCB board/wire
ear plug for mute section
It's possible to develop a "transceiver" (sender&receive as one device)

Letter from Morse/Electronic Poster

An A0 size poster with embedded LED Array, able to listen to morse code from sender and display the message sent. The concept of poster is to mimic Morse's dedication for communication, spoken out and be understood via rapid long-distance transmission, the poster is an funcational object allow workshop participant to test their, and later as the documention of workshop remain in HeK.

Component :

A1 printed poster (594 x 841 mm)
44 characters & 150 LED
Arduino + walkie talkie + mic circuit
wifi sender to web (optional) that same physical poster also display as virtual poster on web page
poster has two modes (live & workshop documentation)
Three layers design (1. tracing paper of orignal print, 2. LED illuminated room of min 15 mm thick wood, 3. LED compartment with 5mm circle of each position, min 12 mm thick)
trial cut 20h30, 18 SEP @ Lucern FabLab
