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 awa...

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. Placem...

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. Transistor fm radio circuit 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. May be useful.

Many of us think that to make walkie talkie is very difficult. But actually to make walkie talkie is not as difficult as imagined. For example, a toy walkie talkie consist of a few transistors. Based on a circuit of walkie talkie toys, we can make a simple walkie talkie. Of course with complete components we are very likely to make it. It's just that the hard component is the inductor for frequency tuning. The inductor for tuning consist of three windings, two windings are combined with three connection point. And one winding are separated for the antenna. For other components, like capacitor and transistor are not difficult for us to find it. I hope this walkie talkie transistor circuit diagram will help you, and your project. Walkie talkie transistor

Transistor Walkie Talkie Circuit Diagram In general, this transistor walkie talkie circuit is the same as other walkie talkie circuit. This transistor walkie talkie circuit, consist of transceiver and audio amplifier parts. But in a walkie talkie circuit, there is an audio transformer, and some are not. Altought different, but both have same function to amplify the audio signal. Transistor walkie talkie circuit diagram Walkie talkie circuit that do not use audio transformer, only use transistor on the audio amplifier, usually consist of four transistor. As for the transceiver circuit, uses only one transistor, but there are also some that use three transistor for more sensitivity. This transistor walkie talkie circuit uses crystal oscillator for frequency stability, while the radio is in transmitter mode. This transistor walkie talkie circuit works the same way as other walkie talkie, that is the change of the circuit during receiver mode and transmitter mode.

This time i will share different walkie talkie circuit. Basically this walkie talkie circuit almost the same as with other walkie talkie circuit. Three transistor walkie talkie It's just that in this circuit using three transistors on the transceiver. Two transistor as receiver and one for transmitter, and the transceiver part is separate. The reason the receiver use two transistors is to increase sensitivity of receiving signals. So the circuit image for this time may be useful.

Basically this one transistor walkie talkie circuit, is the same as with other walkie talkie. It's just that in this circuit, some audio amplifier transistor are replaced with audio amplifier ic. It aims to reduce the size of pcb, so that walkie talkie can be made with smaller size. L2= 3t, 2t, 2t One transistor in question is on transceiver only. This section is the most important on a walkie talkie, because this section serves to transmit and receive radio signals. So it can be used to communicate. For an explanation how this walkie talkie works, we will discuss it later.
