Philosophy

• Make Your Own Device ! (a sub-branch of DIY)


• upcycle & recycle


• Lean ICT & digital sobriety attitude

Session AE491113

• Introduction & recapitulation


• UNIX warm-up


• Exercise 1: Upload images to hon.local screens


• PaperTTY


• 10-minute break


• Discussion : What would You like to make ?


• Making, coding, sharing

Why e-paper ?

• natural
• healthy
• ecological
• minimalist

Any why NOT e-paper ?

Existing devices

• e-readers


• notebooks (onyx)


• phones (Mudita)


• our own devices

What do You need in order to build a digital device ?

Components we are going to use

• Primer :: RaspberryPi Zero, Re-speaker 2-mic array, WittyPi 3, 6-inch e-paper IT8951, 2 x Grove Gesture Recognition systems, Speaker
• Herbarium :: Arduino, 4.3 inch e-Paper UART, 1 x Grove Gesture Recognition
  
• Your project :: 

Design method

• Goal-oriented


• Organic


• combining "Gedankenexperimenten" with physical-stuff (i.e. component) permutations


• collaborative

Coding method

• working with a real-system (advantages ? disadvantages ?)


• tele-computational (derived from Greek τῆλε, tēle, "far")


• command-line based


• collaborative

Collaborative coding

• connect to "cloud" WLAN (password: cirrocumulus)


• open two terminal windows or tabs on Your computer


• window1:: ssh fibel@fibel1.local


• window2 :: ssh pi@hon.local


• in both windows run: screen -S YOURNAME (e.g. screen -S daniel)

UNIX warm-up 0: #root

$ sudo bash

# cd /

# ls /

Projects

Hara

• will be on the wall


• 3 - 5 displays eink


• select keywords, do search, display


• QUESTIONS : what kind of sensors ? what keywords ? how would the algorithm behave ? (how often would the content change ?)


•
