Flyback TransformerFlyback transformer is a separate component of the line scanning unit of a TV set or a monitor. It is used to generate a high voltage at the CRT's second anode and secondary voltages, intended to power CRT's filament circuits, to generate accelerating voltage, to power video amplifiers, to perform frame deflection. It also generates line scanning flyback pulses for the blanking circuit to operate. The product is a conventional transformer with a multiplier in the same package, in abbreviated form - FBT. FBTs also have regulators of focusing and accelerating voltage needed for kinescope's operating function.Flyback transformer performs the basic operability function of line scanning in television receivers or monitors.Line scanning actuating pulses arrive at the prestage, and then are amplified in power. Prestage load is represented by a transistor and a transformer, which matches the preamp with the output stage. From secondary winding flyback pulses go to the output stage. It is built as a circuit with high-power transistor series feed with built-in damper diode. An important function in FBTs is performed by load circuits of line-deflection and frame-deflection coils, which influence the functional process of scanning in television receivers or monitors.Structurally, the transformer is made in the form of several windings of cylindrical form, filled with epoxy resin with a plasticizer. Diodes of the anode section are also filled with resin along with ...

Read Here: I have several previous videos that lead up to this video about simple and cheap laser communication. The system up to this point shown in the video works great for transmitting audio/sound/music via a laser beam. Give your friends a reciever to put in their window and you can transmit some audio to them, as long as they are within range, line of sight and/or mirrors can "bend" the laser beam. Unlike other methods of communication, no transmission wires, license or other hassles come with this method. Disclaimer: There is no need to look into the direct laser beam since it can damage your eyes or someone elses. Still, if complete sound input isolation is needed from the laser communicator circuit, you can try a 1 to 1 transformer, or two 8 to 1000 ohm ones connected together to where the primary is 8 ohms and the final secondary is 8 ohms. If you cant find or contruct a 50K fixed resistor, you can just use a more common 47K resistor. I think it's better to have some adjustability to Rb for various reasons. So then, perhaps a 50K variable in series with say 33K (to prevent your pot from getting dammaged, etc) or something. The next step is to transmit and successfully receive digital computer data with the laser communicator system. I will try the KCS (Kansas City Standard) scheme, but there are others, and I'm not sure what would work the best, assuming at least one method will work though. The clothespin attached to the laser is to apply pressure like a clamp ...
