More than half a century ago, when I was a child, I used to do these kinds of experiments and handicrafts. After that, I did a job related to electronics and radio equipment development, and now I am enjoying my old age by taking up amateur radio communication as a hobby. I watched this video nostalgically. I expect you to become a high level technician.

[romanyarygin]

I'm so jealous to guys, who understand electronics. I understand how elements work separately, but I cannot understand at all, how, and WHY it works in combination. It's total magic for me.

Микро сборки лучше паять на тепло отводе, больше шансов что останутся целыми, и паяльник желательно от 10до 15 ватт, и можно даже заземлить.
В 70е микро сборок у нас не было, были радио лампы и были транзисторы.
Однако в эфир мы выходили 😂😂радио хулиганы были мы.
Увлечение переросло в профессию, 14 лет отработал на ремонте радио теле аппаратуры, сейчас мне 65, но все равно продолжаю ремонтировать свою домашнюю радио и теле аппаратуру.
Привычка понимашь 😂😂😂.

If I am not wrong brown, red, brown is a 120 Ohm resistor not 100 Ohm that would be brown black brown. Besides its is not a crystal. It is an oscillator despite of what Chinese marketplaces that sell that describe as crystals, or translate as crystal. Crystals have 2 pints this have 4 pins and an VCC input. It has a crystal inside but has semiconductors too.

Делал несколько подобных на разные частоты, правда антеннами побольше и с настройкой в резонанс. Дальность 500 м. С усилителем мощности на КТ 646 до двух км.

[jhonwask]

Pretty neat. Haven't made a radio transmitter since the 1970's.

[MRPricks]

I didn't think it was possible wow thank you.

[fifaham]

It is fun to put parts together, what is even more fun to understand the theory behind it and then design your own things.

[TheCubbyman]

Yup, that is a very simple transmitter. the crystal oscillator is actually a complete package in itself. All it needs is a power supply, an antenna, a telegraph key, now you have a low power radio transmitter. You can omit the resistor and your on the air, but you need a low pass filter on the antenna to avoid unwanted interference to other frequencies. ;-D

[rogersmith]

Awesome, I've also seen something similar done with just two pieces of wire!

[andrewjudd-mwmp]

that was my dream as a child and it always was so simple??! :-) fantastic video!

[MathewTitus]

The Crystal Oscillator is the Magical bit. It has a natural oscillation frequency that vibrates with an applied voltage. Vary the voltage and that natural frequency also changes. Hence FM modulation. The rest is just - simple electronics - adding a signal wave to the carrier wave and sending it off through the e.m. field.

[duskintheforest]

I assembled a Radio Shack Science Fair AM transmitter at 10 years old. It worked, but only over short distances like say 1 or 2 houses over. Moving up to an FM stereo transmitter, my range was 7 or 8 city blocks. I'm still a nerd

[israelcarvalho]

Circuito inovador, muito bom parabéns.

[markmalasics]

Amazing! Complete frequency stability, clear full range fidelity, voices and music come through as if it were recorded in 4K and the stereo separation and signal to noise ratios are the best I have ever heard.

[suskun]

Elleriniz dert görmesin emeğinize sağlık gerçekten güzel projeleriniz var.

[teoclark]

zafer kardeşim, sen nasıl bir ustasın ya, hayranlıkla izliyorum, ellerine sağlık

[cptrikester]

Mechanical stuff, I can understand quite easily, but electronic gizmos facinate me. The awareness of the function and applications of each component seems to elude me.

[douggale]

This is one of the things that make amplitude modulation awesome.

[ahmadkhalidhotak]

You are genious person, i have seen your this photo in a lot of electronic circuit blogs, Respect you. keep the good work up !
