Mashable defines Kano as a DIY computer
kit designed to help people of all ages assemble a computer from
scratch, and learn basic coding skills. This DIY takes a Kano and shows
how to drive a littleBits motor with an optocoupler. An octocoupler,
yes. (Too many fancy words already? Stay with me.) An optocoupler, says
Wikipedia, is simply a component that transfers electrical signals
between two isolated circuits by using light. Got it?
Basically,
there are two isolated circuits: 1) The Kano Computer 2) The littleBits
Light Sensor or Motor. The Kano will be used to light up an LED – a
transmitter - and its signal will be sensed by the littleBits Light
Sensor (the receiver) to switch on or off the littleBits motor. The
principle is: when the LED of the Kano is on, the littleBits light
sensor should switch the motor on and when the LED is switched off the
light sensor should turn the motor off. The faster the LED is switched
on and off, the faster the motor will spin – the two factors are
directly proportional.
Once you do
that build a laser mirror spinner using Lego. The maker has beautifully
shown the various steps of construction through neat images. Then, test
the laser spinner using Keno. See a demonstration of this test in the
first video below. After the test is successful, construct a laser
mount, a speaker mount, and a graph paper display screen. Once you
assemble all the parts and put them into operation, together they form
what you can call a Laseroscope. The second video demonstrates how it
works.
