Video selector circuit 4 channels (NAV1, CAM1, CAM2, aux) inputted video signals via a single output giving as video selection buttons is done with circuit PIC16F84 microcontroller is carried out with help other integrated whereas LM1881 (video sync separator) NJM2246 (three input integrated video switch) pic source software written in assembly language. asm code file and the circuit has shams.
PIC16F84A using, you can superimpose the video signal video selector. PIC,LM1881 The availability of dedicated LSI superimpose without bad, PIC for sync separation and LM1881, for switch IC manufacturing reproducibility can only think highly. , the switch was made for the cameras and car navigation system, and soon home The selectors will make a selection of general-purpose camera for the front door.

FET400 Mosfet Amplifier Circuit 400W
All the details of FET400 Mosfet amplifier circuit diagram, PCB, layout description and high resolution images (hq) have 8 ohm speakers with 263 watts RMS and 350 watts into 4 ohms 6 ohms and 406 watts rms power can give. Made the same circuit on the audio input adder circuit using 2 800W power ratio can be 0.5% THD on fet400 4 (n-channel) and IRFP240 (p-channel) MOSFETs used IRFP9240.
Amp’s quiescent current 60mA .. 120mA adjustable between circuit operation voltage of the lowest + – 30 volts DC maximum + – 70 volts DC appear in the image MOSFETs on the mounted mje340 transistor themed as a spectator, as used in the same way must be installed
