12-volt batteries in many applications are being used , of course, to charge the battery in the case according to the quality of a circuit required LM317 circuits built with the 12v 7 y island 4 battery can charge this circuit equivalents ( 7,812 ) low-power ups, inverter devices is also used . Quite low in the cost of the battery charging circuit
Source: kadirlitrac.org Prepared by: ta5coz The following description is taken from the source article .
Circuit 12 Volt and 12 Volt 4 Ah Ah AGM battery is designed for 7 .
This circuit , a voltage regulator output current is limited . Filling ( charging ) current of 600 mA – 700 mA between 4 and 12 Volt or 12 Volt 7 Ah Ah battery can charge like . Set the output voltage Volts 13.5 or 13.8 , you can keep permanently connected to the battery . (PC UPS battery and electric bicycle batteries are filled with the same logic . )
R3 for Vout = 13.8 volts , has been obtained by a parallel connection of three resistors . For R3 4K7 , 4K7 , 47K resistors connected in parallel are used, the output voltage of about 13.8 volts is achieved . LM317 , isolated to be connected to the cooler for cooling soğucu older processors used.

LM35 Thermometer Circuit LM3914 LED
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
