kite design challenge
very practicable
a kite needs to be foldable!

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
a bit clumsy: https://www.youtube.com/watch?v=WI0pGk0MMhg
see Beam's experiment: https://www.flickr.com/photos/contrechoc/52112947630/in/album-72177720298378464/
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:
- Arduino - for intro - school Arduino https://www.arduino.cc
programmable as Arduino, but smaller and lighter:
- ATtiny85: https://nl.farnell.com/microchip/attiny85v-10pu/mcu-8bit-attiny-10mhz-dip-8/dp/1455165?st=attiny85
programmable as Arduino, but smaller and lighter: (needs a programmer)
ordering microcontrollers, electronics
I order online
webshops which deliver fast: (in the Netherlands)
specially for electronics
electronics, Beam's setup from a stepper motor

using a rectifier because of alternating current, then a voltage regulator: https://www.flickr.com/photos/contrechoc/52117231590/in/dateposted/
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.
an old blog of Beam: https://energyharvestingresearch.wordpress.com/author/contrechoc/ e-textile summercamp workshop: http://etextile-summercamp.org/2014/capacitor-energy-harvesting/ Beam interaction station page: http://interactionstation.wdka.hro.nl/wiki/Research/Research2014-2015-Beam#Research:_Design_and_Energy_Harvesting
applied in this elective: generate energy for sending a morse code for a LED
