Simple fm radio circuit diagram

FM radio is an FM broadcast radio receiver (frequency modulation) that has the advantage of being able to transmit broadcasts in stereo format.
despite having the advantage of sending stereo broadcasts, FM waves have a relatively short range. many electronic hobbyists want to make their own radio fm, but many circuit schemes use ic fm, and this is considered less challenging.



the fm radio circuit scheme consisting of several transistors is a circuit scheme that is sought, because it is easier to understand how it works. this time I will share the fm radio circuit scheme consisting of several transistors. 
some parts of the scheme of the FM receiver radio circuit use transistors, such as the RF amplifier, tuning, and if amplifier parts. with the use of transistors in the FM radio circuit scheme, this series can be used for learning materials about how a FM radio receiver works.

super ceramic and future of aviation

At present the world of aviation has been very advanced, this is evidenced by the rapid intercontinental flights, and accompanied by increasingly cheaper costs. All of this can be realized with the use of super materials, in the constituent components of an aircraft.



To reduce flight costs, one way that can be applied is by reducing the weight of aircraft. In this way the aircraft fuel consumption becomes more efficient, so the cost of flights will be cheaper.
To reduce the weight of an aircraft, for now using lightweight and strong carbon fiber and aluminum alloy materials. This material is very strong and has a light weight, so it can be used to make aircraft parts.
In addition to the development of the fuselage, the scientists also developed another important part of the engine. As we all know airplane can take off, and fly because it gets thrust from a jet engine.
Jet engines are one of the strongest engines on earth besides Rocket engines. The jet engine is able to suck large amounts…

Simple fm receiver circuit diagram

FM receiver or FM radio is the most popular radio receiver for now. Its advantages, among others, can be used to transmit broadcasts with stereo format. So the music show on FM radio has better sound quality than AM radio.

Many of the analogue electronics hobbyists consider that to make an FM receiver quite difficult. Because, many of the FM radio circulating using ic receiver so this makes us think it will be difficult to make it simpler. 
For this time I will share the FM receiver scheme from the electronic kit of the 90s, and the receiver scheme is quite easy to make because it uses only some electronic components only.

Basically this receiver scheme is a rf circuit amplifier, oscillator, and audio amplifier made very simple. Hopefully this FM receiver scheme can help you with your FM receiver project.





Walkie talkie circuit diagram

In this modern era all electronic devices have grown rapidly. Starting from home appliances, communication tools, vehicles, and much more. It used to communicate telephone lines using cables, to apply radio frequency waves for home phones to mobile phones.
In addition to being applied to telephones, radio frequency waves also have long been applied to two way radios or walkie talkies. In the eighties, walkie-talkies were very popular to communicate at close range. And many walkie talkie kits are available on the market almost all over the world. 
But for now walkie talkie kits are hard to find, but still available in some online stores. For people who have a hobby of electronics, making your own walkie talkie is a fun thing. There is a certain satisfaction when we can make wireless devices with our own hands. For that moment I will share a series of walkie talkie toys that many circulating in the market.




This walkie talkie circuit is quite easy to make, because it only consists of severa…

The farthest man-made machine

Have you ever wondered, what is the furthest thing that man has made? Perhaps many think, that man-made furry thing is mars lander. Or maybe a satellite to research jupiter. However, in fact the man-made furry thing is a pilotless aircraft with ancient technology.



The plane was a voyager 1 launched on September 5, 1977. The main mission of the voyager 1 was to investigate the planet of jupiter and saturnus, but improved again to examine the heliopause and interstellar space. On March 5, 1979, voyager 1 reached the planet of jupiter, and on November 12, 1980 the voyager 1 reached the planet of saturnus.
The voyager 1 power is 420 watts, sourced from thermoelectric generator radioisotopes. To communicate with the earth, voyager 1 uses a power transmitter of only about 22 watts, and it takes about 36 hours to communicate with the station on earth.
In 2015 the voyager 1 distance from the earth is about 19.7 billion kilometers, and to date the voyager 1 continues to go and away from our solar…

looking to the past with James webb telescope

Have you seen stars in the sky? What do you think of when looking at a star? Perhaps all you can think of is, the stars in the sky are very far away and there is no way we can go there. But, in fact the stars in the sky are not only far away. Stars in the sky are thousands of years, even millions of light years. That means, the starlight in the sky comes from thousands of years ago. So the light we see is light that comes from the past.




For hundreds of years, astronomers have been researching stars in the sky using telescopes. In general, telescopes used are optical telescopes, which have very limited capabilities. Along with the development of the era, telescopes continue to improve technology until its ability continues to increase.
The development of telescopes is not just telescopes on the surface of the earth, but until the telescope in space. In the eighties, scientists made the hubble hubble space hubble telescope, to be placed in orbit around the earth. Placement of telescopes in…

The simple transistor fm radio circuit

Fm radio is a radio reception fm waves. These radio receivers some are fully using transistors, and some are using ICs. For those who use transistors usually called transistor radios.
With the rapid development of the times, the radio changed into smaller ones,  and with few components. And changed from analog system to digital system. Some analog electronic enthusiasts, transistor radios have a special place.


Dispite its simplicity, it is easy to repair and modify. To help you and your transistor radio project, here is a transistor radio picture. Which you can use to create and learn it.
