Basic Automatic Day-Night Lamp with LDR

Maybe it's a lot who know how to work this one series, but I wanted to share back to the beginner on this. In the existing lighting circuit automatic lights that use components LDR (Light Dependence Resistor).



The workings of LDR LDR is exposed to light if the layer of the resistance was weakened likewise if there is no light at all resistance enlarged. here could make friends like that, because its components are a little easy but we will use the 220V AC voltage of course you must be very careful. Rather than actually being burnt. The author asks to be careful for the beginner course.

Schematic LDR

LDR components can be interconnected with a cable, so tools stay in the house but LDR is outside the home. It is recommended using qualified Relay no1 to avoid fire, because the relays are cheap to produce heat. Relay that cheap is not in use for high voltage. Travonya use the cheap, because this circuit does not require large currents. The function of Potensio 500KΩ to regulate Q1 & Q2 is on, if both the active transistor relay also participate actively.

1500W Stereo Power Amplifier Schematic

Circuit Power Amplifier has a power output of up to 1500W RMS power amplifier circuit is often used to power sound systems keperlun for outdor. In the final image can be seen a series of power amplifiers using 10 sets of power transistors for the ending. This power amplifier circuit using a transistor amplifier from the front, signal splitter, driver and power amplifier. Current consumption required is quite large power amplifier that is 15-20 A 1500W power amplifier circuits for this. Supply voltage needed by the power of this amplifier is the optimal working order symmetrical 130VDC (130VDC-130VDC ground). 1500W amplifier circuit below is a picture series of mono, stereo if you want to make it necessary to make two copies of the circuit. For more details can be viewed directly image the following 1500W power amplifier circuit.

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.
