range. T1 which type of transformer. what is C1 value. what means of letter P which in in capacitors like C5 and C8. which type of antina will be best for this and how much is its range. T1 which type of transformer. what is C1 value. what means of letter P which in in capacitors like C5 and C8. which type of antina will be best for this and how much is its range. T1 is an IF transformer as seen in FM tuner this is a color green IF with capacitor at the bottom, p means picofarad a unit for ceramic capacitor, pls look at the diagram C1 symbol is non polarized capacitor, 10uF value is a tantalum capacitor R8 Comes from Transformer going to C4, forget that whole side of the circuit because it just deals with Audio, you can build your own Audio amp and couple it in to the Oscilator or final stage through C4 ²s Capacitor, just wire your Headphone out from Pre-Amp to C4, and hook Ground, So Speaker + Y I am constructing a TV Transmitter my self, different design. Good Luck, and don`t be asking me a whole load of questions, because I`m just passing by this site. I will be interested if you can supply me with details of circuit design calculations of a low cost, UHF, 3-5 km, audio/video/data transmitter and receiver, for i am to design and construct one for my project. thanks
This project fits more for custom made battery casing that can have more space to hide things inside. This switch with few alterations can be used for any other project as well but is designed based on e-bike needs! This project use a clever functionality of....
The circuit described here uses ultrasonic oscillations and operates based on the propagation velocity of these oscillations in the air. Thus, we can easily determine the distance of two points if the time within which the wave travels this distance is....
Sometimes the precious metals are hidden too deep and are not detected except with complicated devices. In many cases, however, small pieces of precious metal buried near the surface can be detected by relatively simple means. Everyone is very attractive to....
Many times for various reasons we forget or can not water the plants that we have in our homes. And many humidity sensors units just notify us with a beeping sound or with a flashing light, that the pot needs watering. But what if we are away from home? This....
The principle behind a metal detector is really very simple. Proof of this is the circuit that follows, in which it proves that the construction of a metal detector can be done in the minute, with few components that we find very easily everywhere. With the....
The sub-harmonic bass generator is a sound producing unit for guitars. The sound it produces looks very much like that of the bass guitar. The octave generator is sometimes quite unusual since it does not produce any of the usual ways of coloring the sound,....
In the past the sounding (sea bottom measurement) was done with the "bullet", that is, with a heavy lead object that the seamen plucked into the sea hung from a calibrated rope. As soon as the "bullet" reached the bottom, the depth appeared directly from the....
This Amplifier was designed to have the following specifications: Distortion less than 0.1% at full power of 100W even at 20KHz. Power has to be attributed to an extended bandwidth. The output transistors must be protected against short circuits. The power....
A series of LEDs serve to alert the gardener when plants need water. Using two conventional digital integrated LEDs and a series of LEDs, we make a very useful device for gardening. The device detects the amount of water in the pot and alerts the grower.....
