Sketching with HW – SoSe2020

Leaning Goals:

  • Sketch with programmable Hardware
  • Build basic circuits connected to the microcontroller
    • Output: LEDs, Servos, Motors, Speakers, Display
    • Input: buttons, Dials, Light sensitive resistors, accelerometer, distance, I2C sensors
  • Program and Debug MicroPython on ESP32
    • Input, Output
    • Networking
  • Envision a new interactive physical object and implement a functional prototype

Topic of this terms course: Connected objects

Examples:

  • A toy for an animal connected to a representation of it on the owners desk
  • The fridge door in the shared flat connected to a bracelet
  • Two chairs connected to each other representing the others usage

Requirements:

  • At least two connected physical objects (can be more)
  • At least one object has to have 2 or more sensors
  • At least one object has to have 2 or more actuators
  • Object can be different (e.g. dog toy and ball on the users table) or symmetric (e.g. two chairs)
  • One sensors has to be “invented”
  • The object need to communicate over the internet

Timetable

Kick-off Meeting (90 Minutes, Zoom), 27.7.2020 at 17:00 – life online event

  • Introduction of the topic and format
  • Showing examples of the hardware and tools
  • Talking about resources
  • Introducing participants and teachers
  • Building of groups of 3 or 4 students – groups will work remotely
  • Kits can be picked up (or shipped) to students individually.

Preparation phase (self-paced)

10.8. to 28.8.2020

  • There will be tasks and explanation videos provided.
  • We will have a Discord Server were you can log in when you are working on your project.
  • This way you can talk to the other students and help each other out and chat.
  • On workdays, there will be at least one knowledgeable person in the virtual lab so you can get help.

Individual Tasks (6)

  1. Online exploration of Micropython, [5]
  2. Getting the ESP32 Hardware running; Blink internal LED, Print to serial line
  3. Output: LEDs with resistors, RGB LED, PWM
  4. Input: buttons, Poti, Light sensitive resistor
  5. Mini System: connecting a servo to a poti, print to Display
  6. Networking: storing and retrieving variables from the cloud Group Task
  7. Networked Mini System: generating sound on one ESP based on distance from another ESP

Group Task

Networked Mini System: generating sound on one ESP based on distance from another ESP

For each task a short video (up to 30 seconds) showing the working system and a screenshot showing the code is required. Preferably, we get from each student a video with 6 short videos and a single Document with all the screenshots (task 1 to 6). Deadline is 28.08.2020. Each group has also to provide one video for the group task and prepare an idea for their connected object – presented in a video of up to 2 minutes. Deadline is 28.08.2020.

Intermediate Meeting

(90 Minutes, Zoom), 31.08.2020 at 5pm - live online event

  • All group project proposals are presented (if you cannot make this date, you may submit a video recording of your idea)
  • Discussion on feasibility
  • Discussion of time plan

Project phase (self-paced in groups;

expected time required: 4 days full time)

  • Each group sets a time plan and hands it in
  • Each group makes a shopping list for things required
  • Each group defines 3 milestones (what is achieved when)
  • Each group makes meetings with teaching staff, will put this on the web page so others can drop in'
  • Individual sessions for help are available over zoom
  • Each group makes an individual date to learn about the lab (soldering) and laser cutter

Final deadline of the project:

30.09.2020 (you can hand in earlier!)
Video containing:

  • The realized project vision like an advert (showing your functional prototype) ~ 30 seconds
  • A description of your the system with some detail of what you built/programmed ~ 3 min
  • Making off of your system showing impression from your development ~ 5 minutes

Documentations:

  • Abstract of the project vision (200 words),
  • building plan/schematic,
  • code,
  • photos in a single PDF

Group feedback session after handing in (20 Minutes Zoom call)

Public presentation either at the open lab day in WS 20/21 or on the webpage.
