elective main learning goals

making - on two levels

  • design part: kite, shape but also dynamics - something that lifts of in the air
  • design challenge or mission - generation of energy (solving the emergency) by using wind

making - styles

  • improvised making
  • being able to switch between materials and technology
  • reflection on what you make - how to improve

making with uncertainty

  • not being expert in either kite design or energy - how to deal with this?
  • stay in your flow zone - yes, easier said than done :-)
  • you start with all kinds of unknown techniques, materials, concepts - coping strategies
  • try out, make mistakes, fail and go on
    • learning is only be done by making mistakes, so mistakes are not at all catastrophes, errors or stupid!!!!
    • making mistakes: loss of time, money....yeah - that is learning - but then it is not wasting time!
    • stress - yeah that is learning - try to keep yourself balanced
    • this is psychology - yes of course :-)
    • if you see something beautiful, or somebody performing well .... be sure the person has put a lot of time and effort into it - and has suffered to get at this level.
  • resist giving up
  • reflect, take time for new approaches
  • ask advice
  • really practice sometimes, till you get it
  • be on the look out for other ways, even other subjects
  • remember your solutions, for other cases

making - reflections

  • practical making
  • critical making
  • investigating making

different learning domains

  • making
  • working with materials
  • working with tools and machines
  • integrating technology
    • electronics
    • microcontrollers
    • programming
  • testing, going out and fly the kite
  • check your goals
    • what is the energy coming out
    • did the kite fly well
    • was it designer fun
    • how can this be improved?
  • what did I learn
    • how will I try this differently the next time

ways of kite making

Prototyping: DIY, cheap, fast

making a small tetrahedral kite from straws: http://mathandecon.councilforeconed.org/35/visuals/lesson7_activity.pdf

Professional

Then you need more expensive materials, good sewing skills, experience with kite making, ideas, kite passion

and a lot of practice making

but you need to be very inspired for this one: (not my own) https://www.flickr.com/photos/contrechoc/40654374043/in/album-72157707131754945/

special kite design challenge

very practicable

a kite needs to be foldable!

for this elective I propose the delta , which is foldable: https://www.flickr.com/photos/contrechoc/47906437801/in/album-72157707131754945/

propellor making

we will start "propellers" folding rotating thing: https://www.youtube.com/watch?v=6MJ2eDFSklA

Other kinds of small wind turbines:

basic electronics

what is V - Volt - symbol V

what is Ampere - current - symbol I

what is resistance - symbol R

Law of Ohm connect V and I and R: V = I times R - this seems simple but can get complicated when several circuits are combined.

what is a circuit?

basic electronic components we will use

electonic components is series

electronic components in parallel

battery - producer of energy has a voltage

wire - is conductive - connects components

resistor - any component has a resistance and gives a drop in voltage

diode - something that lets current through or not depending on the direction - also has a voltage drop - LED

speaker - transfers energy into sound

electromotor - either makes rotation - movement - from voltage and current (electric energy) or makes electricity from rotation (as a generator)

advanced

voltage regulator - prevents voltage above a certain boundary, for instance 5V

rectifier - makes DC current from Alternating current

electro motors

typically designerish: exploring into a very specialised field ... as naive as a baby....:-)

a bit clumsy: https://www.youtube.com/watch?v=WI0pGk0MMhg

see Beam's experiment: https://www.flickr.com/photos/contrechoc/52112947630/in/album-72177720298378464/

and try this one:

Making smallest DIY dynamo motor: https://www.youtube.com/watch?v=nCplwikusyw

Advanced explaining and using a stepper motor:

Making generator from stepper motor: (using h-bridge, capacitor)

mini wind turbine: https://www.youtube.com/watch?v=938dTRrwrYc (a test if it is worth the trouble of printing)

(well commercially .... but for "learning"!!!!)

this is the turbine he is talking about: https://www.amazon.nl/TEX-Energy-Infinite-Ausgangsstrom-Micro-USB/dp/B075RF17NV/ref=sr_1_1?__mk_nl_NL=ÅMÅŽÕÑ&crid=1064Q9X69FI5I&keywords=Infinite+Air&qid=1654454500&sprefix=infinite+air%2Caps%2C158&sr=8-1

pretty big for our kites....

why not using these bigger motors???

advanced: electrometers are ... complicated...https://www.youtube.com/watch?v=AdNVg1MWc8c

see also the links in the description of this video


so here we conclude ... yeah, but is is very speculative....

microcontroller

a microcontroller can be programmed to open or close circuits

we will use this to try to send morse code from the kite

needs energy, which comes from the electrometer which is rotated by the wind

script for Attiny85 on kite: https://github.com/contrechoc/watchdog_for_kite/tree/main

For this elective - microcontrollers:

programmable as Arduino, but smaller and lighter:

programmable as Arduino, but smaller and lighter: (needs a programmer)

using a script with a "watch dog timer" in the ATtiny85

energy harvesting

collecting small amounts of energy and transfer this into electricity

  • movement, vibration
  • temperature differences
  • solar energy
  • radiation energy, for example WFI
  • plant energy, like algae, or bacteria around roots of plants

what is "small"?

what to do with small amounts of energy?

  • collect data, like temperature, pollution
  • send data to a bigger device

very small devices, small batteries, specialised chips, for example LTC

very small energies: not something that charges your smartphone.

applied in this elective: generate energy for sending a morse code for a LED
