00:00:00

in this video I will show you how to make a

00:00:03

generator using the KT315 transistor and

00:00:08

conduct several experiments with it.

00:00:11

The transistor looks like this. An

00:00:16

old Soviet good transistor

00:00:19

can be used with any letter index.

00:00:22

yellow-orange. They all work; they are

00:00:25

powered by a blocking generator from one

00:00:29

3-volt battery, which means

00:00:34

coil base coil all of them are

00:00:37

wound three coils on one and the

00:00:40

mandrel is wound the

00:00:42

diameter of this mandrel is five and a half

00:00:44

centimeters the base coil contains 40

00:00:51

turns the collector coil contains 35

00:00:57

turns of the same wire approximately

00:00:59

012 014 millimeters and the coil that

00:01:03

captures this energy in place with the

00:01:07

LED is the same the diameter is only

00:01:10

130 to 150 alternating, so you

00:01:13

need to make turns of the same wire and

00:01:18

now check this generator with the

00:01:21

help of a coil and an LED, supply

00:01:24

power, these two coils are

00:01:27

a little at a distance from each

00:01:29

other

00:01:33

if you bring

00:01:36

this cisa LED with a coil to the collector coil then

00:01:40

the LED above the collector on the coil

00:01:41

begins to light up the closer the closer, the brighter the farther

00:01:44

away, here it all

00:01:46

stops shining, and now this

00:01:50

base coil, in order to increase the glow,

00:01:52

must be brought to

00:01:54

the collector and achieve maximum

00:01:59

generation, approximately it will be

00:02:02

here and now I take the coil and

00:02:07

already at a distance of about 8 centimeters

00:02:10

the LED lights up,

00:02:26

this is a common experience of the so-called

00:02:30

electromagnetic induction, and now to

00:02:34

increase this induction I took a ferrite

00:02:37

rod from the magnetic antenna, the LED

00:02:40

now does not light up, and now I take it by

00:02:45

inserting a coil into the coil and the holy pack is

00:02:51

now lit now I can

00:02:54

move it along a ferrite rod and it

00:02:57

will light up all over this ferrite rod,

00:02:58

although of course it will fade away

00:03:00

slowly, but all over the ferrite master

00:03:03

it will burn and the next experiment

00:03:13

is called a radio DJ, the

00:03:16

collector coil is the base one, I

00:03:20

will manipulate it, the generator

00:03:24

is working and there is a receiver nearby, free

00:03:29

from broadcast radio stations, but who has a

00:03:31

slender range and the latest experience is the

00:04:13

so-called modulation of the base coil, the

00:04:19

fixed collector is located

00:04:22

so that silence can be heard in the receiver,

00:04:25

the receiver is tuned to medium waves,

00:04:28

and when I knock on it like that, a

00:04:35

loud sound will be heard if you talk near this coil,

00:04:38

if it is on some kind of

00:04:39

membrane, then

00:04:41

the sound of the voice will also be heard, now I turn it louder

00:05:19
