VU Meter with LM3914, volt meter can be made clear signal to the T & Cs though the display drivers, according to the established circuit gives the output based on the output, LED lights, etc. transistor goes to the transmission. LM3914 by the burning temperature of the thermometer 30 LEDs used in the application.
Heat sensor that is used for detection lm35z LEDs are illuminated by ambient temperature sensitivity can be adjusted with potentiometer on the circuit

TDA7294 Car Subwoofer Amplifier Circuit TL494 DC to DC Converter
Probably the most sold TDA7294 integrated amp bass amp became one of the TDA7294 this application even though the car is designed to be used in part thanks to the TL494 controlled SMPS circuit 12v battery voltage symmetrical entered as 2x40v upgraded.
To take full advantage of integrated TDA7294 supply voltage selected at the highest level, but you get the information you want a good cooler cooling fan must be connected even on the circuit TL072P also filter op amp has adjustable bass frequency. EI33 transformer SMPS used in section 1 and section input output coil windings 2 × 2 × 5 laps 14 laps the car amp pcb design of the project, the layout is very stylish worth doing
