Skema Rangkaian Saklar Cahaya Otomatis
Skema Rangkaian Saklar Cahaya Otomatis ini sangat cocok untuk memberi penerangan sementara ketika suatu ruangan menjadi gelap akibat putusnya aliran listrik atau terjadi korsleting dan akan memberi penerangan selama jangka waktu tertentu antara 1 jam sampai dengan 5 jam bisa diatur.
Skema rangkaian:
The switch is a semiconductor relay S202DS2 and the oscillator is 4060.
Cara kerja rangkaian:
From the moment that T4 and T5 are opened, relay’s LED start to light and powers the lamp. As soon as one of the transistors is blocked the lamp will go OFF. The phototransistor T3 will be the one that blocks T5 if there is light that falls on T3. The T2′s base-emitter junction is connected in parallel with T3 and so will be blocked as long there is light. T2 will continuously resest IC1 whose counter outputs will be in “0″ state.
When the night falls R7 provides base current for T2 and the transistor starts to conduct. The counter can now starts to count the impulses from the internal oscillator and in this time the light will bulb will stay lit. After a time, when the output of Q13 goes in state “1″ T4 is blocked. This causes the relay’s LED to go off and the lamp too.
There is no need for external power supply because the light sensor switch is powered directly from the 220V mains. D1 … D5 diodes rectifies the voltage and C4 filters it.
C5 is working as a resistor so will need to have the working voltage of minimum 400V but the 630V is preferable.
S202DS2 is a Triac-Full-Wave-Output Optocoupler produced by Sharp Electronics in a TO-220 package.
The maximum peak-to-peak voltage is 600V, max on-state current is 8 Ampere and the input trigger current is 8 mA.
Caution! This circuit is powered directly from 220V. Attention will be given for appropriate isolation of the switch block.

Inverter 12VDC to 220V 50Hz 500W
Rangkaian Inverter 12V DC ke 220V AC 500W.
Merangkainya cukup mudah dan harganyapun murah.
Friends favorite circuit about the the inverter, because like working outdoors, or to backup storage to use when necessary.
Most of this is circuit low power, which is not suitable for practical applications. My friends said that he would be about 500 Watt.
It is a good size. Use with television receivers and light bulbs as well.
When looking for circuit. I get headaches. If you are a beginner or I can not buy expensive good quality circuits. Requires only one transistor. Or if you have free time. I want to build old circuit is alive again. This circuit will accommodate all your needs. It is a simple circuit. The same principle, I take battery voltage 12V to produce a oscillator about 100 Hz and pass to a two frequency divider circuit is only 50HZ. And drive a 10 ampere transformer with 10 x 2N3055 transistor in parallel. By a single transistor has 2A, when I use 10 transistors or 5 pairs of drive high current output. The complexity of circuit, but the principle is not it, and it is the number of transistors on a basic, easy to buy.

Rangkaian Robot Sederhana
Ini rangkaian robot line follower yang sangat sederhana. Dalam perancangan robot tidak diperlukan adanya pemrograman. Yang digunakan disini hanyalah respon dari sensor untuk mengaktifkan motor sebagai gerakan robot.
Led digunakan sebagai sumber cahaya. Cahaya dari led dipantulkan dengan intensitas yang berbeda tergantung warna dari bidang pantul. Sensor dari LDR akan bereaksi terhadap perubahan intensitas cahaya yang diterimanya.
Pada lintasan warna hitam LDR akan menerima lebih sedikit cahaya dari pada saat lintasan putih (warna hitam menyerap cahaya lebih banyak sehingga yang dipantulkan sedikit), pada saat ini motor DC akan berputar lebih pelan (arus kolektor berkurang), dan sebaliknya.

Rangkaian Detektor Sinyal Handphone
Ketika Handphone anda dalam keadaan Silent atau Diam karena sesuatu hal yang mengharuskan HP kita tdk boleh berbunyi, misal ketika sedang melakukan rapat atau saat melakukan Sholat atau ketika berada di tempat ibadah maka kita bisa mengetahui adanya panggilan masuk atau ada sms dengan sinyal cahaya yakni dengan menggunakan Alat Detektor Sinyal Handphone. Alat ini akan bekerja atau menyala ketika ada sinyal RF dari Handphone.
Rangkaian Detektor Sinyal HP
Cara Kerja Rangkaian:
Op-amp IC CA3130 (IC1) is used in the circuit as a current-to-voltage converter with capacitor C3 connected between its inverting and non-inverting inputs. It is a CMOS version using gate-protected p-channel MOSFET transistors in the input to provide very high input impedance, very low input current and very high speed of performance. The output CMOS transistor is capable of swinging the output voltage to within 10 mV of either supply voltage terminal.
Capacitor C3 in conjunction with the lead inductance acts as a transmission line that intercepts the signals from the mobile phone. This capacitor creates a field, stores energy and transfers the stored energy in the form of minute current to the inputs of IC1. This will upset the balanced input of IC1 and convert the current into the corresponding output voltage.
Capacitor C4 along with high-value resistor R1 keeps the non-inverting input stable for easy swing of the output to high state. Resistor R2 provides the discharge path for capacitor C4. Feedback resistor R3 makes the inverting input high when the output becomes high. Capacitor C5 (47pF) is connected across ‘strobe’ (pin
and ‘null’ inputs (pin 1) of IC1 for phase compensation and gain control to optimise the frequency response.When the cell phone detector signal is detected by C3, the output of IC1 becomes high and low alternately according to the frequency of the signal as indicated by LED1. This triggers monostable timer IC2 through capacitor C7. Capacitor C6 maintains the base bias of transistor T1 for fast switching action. The low-value timing components R6 and C9 produce very short time delay to avoid audio nuisance.
Assemble the cell phone detector circuit on a general purpose PCB as compact as possible and enclose in a small box like junk mobile case. As mentioned earlier, capacitor C3 should have a lead length of 18 mm with lead spacing of 8 mm. Carefully solder the capacitor in standing position with equal spacing of the leads. The response can be optimised by trimming the lead length of C3 for the desired frequency. You may use a short telescopic type antenna.
Use the miniature 12V battery of a remote control and a small buzzer to make the gadget pocket-size. The unit will give the warning indication if someone uses mobile phone within a radius of 1.5 meters.
