Battery Charger LM317 Circuit Diagram

Lead Acid Battery Charger circuit is highly recommended to recharge battery. And recommended that maximum voltage 24V 7A battery, so you can recharge a battery simultaneously. Battery Charger has been little use of several components such as diodes, electrolytic capacitors, transistors, resistors, and also for strengthening of the voltage and current stresses. And also do not forget to lowering electric voltage 220V to 20V-35V 5-10 Ampere suitable for Lead Acid Battery Charger circuit.

List of components for the circuit Lead Acid battery:

R1 = 1Ω 2w

R2 = 100Ω

R3 = 220Ω

R4 = 10KΩ Trim

D1 - D5 = IN4004

Q1 = BC547

IC 1 = LM317

C1 - C2 = 1000µF 50V

C3 = 470µF 50V

Transformer I mentioned above can use the 5A - 10A with a secondary voltage of about 20Volt-35Volt AC. My advice to IC please be cooler, because when the circuit and well even IC LM317 works it causes IC hot. Also to assemble the components using PCB (Printed works Circuit Board) qualified with a good track, as well as the components that will be used not forget to check back whether good or not, so it will also produce good results.

NE566 Function Generator Circuit Diagram

The NE566 Function Generator is a Voltage-Controlled Oscillator of exceptional linearity with buf fered square wave and triangle wave outputs. The frequency of oscillation is determined by an external resistor and capacitor and the voltage applied to the control terminal. The Oscillator CAN be programmed over a ten-to-one frequency range by proper selection of an external resistance and modulated over a ten-to-one range by the control voltage, with exceptional linearity.

TDA2030 complete tone control

At this time I present a series of amplifiers that use IC TDA2030, but this series is equipped with a tone control. Tone controls include Bass, Treebel, and Volume. Power amplifier and tone control has been put together in a single PCB. As well as its power supply circuit was also used as one with the power amp, and tone control. Making it easier in the installation and will look neat. Schematics Layout PCB PCB design This amplifier is a mono amplifier type, can be modif for guitar amplifiers. If not coupled amplifier (mic preamp) then you must deactivated potensio treble and bass, why? because if not using a mic preamp and still maintain potensio treble and bass sound input (input) from the guitar will not or the maximum discharge is not tight on the speakers. So you must deactivated a way to decide which directly connected capacitor with the tone control circuit, and capacitor were connected directly to potensio volume and input jack.

Simple Preamplifier and High to Low impedance Converter Circuit Diagram

This is the Simple Preamplifier and High to Low impedance Converter Circuit Diagram. This circuit matches the very high impedance of ceramic cartridges, unity gain, and low impedance output. Simple Preamplifier and High to Low impedance Converter Circuit Diagram By `loading` the cartridge with a 2M2 input resistance, the cartridge characteristics are such as to quite closely compensate for the RIAA recording curve. The output from this preamp may be fed to a level pot for mixing. Sourced By: Circuitsproject
