2. Rangkaian Pengusir Tikus
.
Daftar komponen Rangkaian Pengusir Tikus elektronika:
R1 … 1K
R2,R3 … 15K
C1 … 1nF
C2 … 1uF/16V
C3 … 10nF
C4 … 220nF
C5 … 1000uF/16V
D1.D4 … 1N 4001
IC1 … 555
Tr1 … Trafo 6V/200mA
TD1 … speaker tweeter bentuk corong
F1 … Fuse/sekring 50 mA
Rangkaian Pengusir Tikus Elektronik adalah sebuah oscilator yang mengeluarkan gelombang ultrasonic pada kisaran frekuensi 20 – 40 KHz. Gelombang ultrasonic yang dihasilkannya tidak akan terdengar di telinga kita tapi akan sangat mengganggu sekali bagi telinga tikus.
Untuk menghindari tikus menjadi kebal terhadap Rangkaian Pengusir Tikus Elektronik, maka Base Frequency dimodulir dengan signal 50 Hz yang didapat dari frekuensi tegangan jala-jala PLN melalui kapasitor C4 sehingga akan dihasilkan ayunan frekuensi antara 20 – 40 KHz secara periodik. Efek yang dialami tikus akan terasa sangat dasyat, seolah-olah seperti kita berada pada sebuah konser music amburadul dengan irama yang acak-acakan dan tidak bisa dinikmati sama sekali, plus sa’at itu kita lagi sakit gigi!! Bisa dibayangkan, music trust-metal mungkin masih jauh lebih indah dibanding suara alat ini
Jantung rangkaian pengusir tikus elektronik adalah sebuah IC tipe 555. Gunakan loudspeaker dari piezo electric atau speaker tweeter bentuk corong agar frekuensi ultrasonic-nya lebih nendang dan efektif. Pengusir tikus elektronik ini efektif untuk ruangan seluas maksimal 200 m2 asal penempatannya tepat. Bisa diletakkan di pojok atas ruangan agar frekuensi noise-nya bisa menyebar ke seluruh ruangan tanpa halangan. Nyalakan secara terus menerus untuk menjaga agar tikus tidak datang lagi, tidak usah khawatir dengan konsumsi listriknya karena daya listrik yang dibutuhkan cukup rendah, masih lebih besar lampu bohlam 5 watt/220 volt. Pengaturan frekuensi dsb. tidak diperlukan pada Rangkaian Pengusir Tikus Elektronik ini.
3. Skema Saklar On-Off DigitalSaklar On-Off Digital ini merupakan saklar yang bekerja untuk menghubungkan arus listrik dan memutus arus listrik dari sumbernya. Cara kerja dari rangkaian ini adalah, apabila pada switch on/off ditekan maka relay akan tertutup atau dalam kodisi on, dan jika ditekan kembali maka relay akan terbuka atau memutus aliran listrik ke kondisi off.
Rangkaian ini sangat sederhana hanya terdiri dari beberapa komponen. Anda bisa menggabungkan atau menerapkan aplikasi rangkaian ini misalnya ke peralatan Audio (amplifier) yang pernah anda rakit sebelumnya ataupun diaplikasikan untuk peralatan elektronik lainnya, sehingga anda tidak lagi menggunakan saklar manual, lebih kereeen khan ?..
Pada umumya peralatan elektronika modern saat ini sudah tidak banyak yang dioperasikan secara manual (saklar manual) dan tergeser oleh peralatan elektronika yang dioperasikan digital. Rangkaian saklar on/off dibawah ini adalah salah satu contoh operasi digital :

Rangkaian elektronika pengusir nyamuk yang saya berikan ini termasuk dalam rangkaian elektronika yang sederhana. Karena kesederhanaannya inilah yang membuatnya mudah untuk dipelajari bagi seorang pemula sekalipun. Selain itu, untuk membuatnya tidak diperlukan biaya tinggi alias sangat murah. Namun demikian aplikasi dari rangkaian ini tentunya tetap sangat bermanfaat dalam kehidupan sehari-hari kita yaitu mengusir nyamuk dari rumah kita. Bahkan dengan alat ini kita juga dapat menggunakannya diluar ruangan, semisal ketika ngeronda ataupun sekedar santai di halaman.
Selain sebagai pengusir nyamuk, rangkaian ini juga bisa digunakan pada jenis serangga ataupun jenis binatang penggangu lainnya. Contohnya adalah pada kecoa dan tikus. Prinsip utama bagaimana rangkaian ini bekerja adalah dengan berdasarkan bahwa serangga atau jenis binatang pengganggu lainnya sangatlah sensitif kepada beberapa frekuensi suara, terutama frekuensi suara yang tinggi. Dengan demikian, disaat rangkaian ini dihidupkan akan membuat jenis-jenis hewan tersebut merasa terganggu dan menjauhkan diri dari alat ini. Berbeda dengan manusia yang tidak dapat mendengar frekuensi suara yang tinggi, maka tentunya tidak akan menyebabkan gangguan suara bagi kita yang berada didekatnya sekalipun.
Untuk gambar dari rangkaian elektronika pengusir nyamuk sendiri, banyak rupanya. Namun saya coba pilihkan yang paling menarik untuk dicoba aplikasikan yaitu bekerjanya secara otomatis karena dikendalikan oleh Light Depending Resistor/ LDR. Alat ini akan menyala dengan sendirinya bila berada di lokasi yang gelap, dan sebaliknya akan mati bila dilokasi terang. Dengan begini alat akan otomatis bekerja jika lampu kamar kita dimatikan.
Perlu diingat kembali ya bahwa rangkaian ini menggunakan speaker untuk mengeluarkan frekuensi yang sama dikeluarkan oleh nyamuk jantan. Pada waktu bukannya musim untuk kawin, maka nyamuk betina akan menjauhi frekuensi ini. Dengan begitu nyamuk betina yang menghisap darah tidak akan ada disekitar alat ini, sedangkan nyamuk jantan memang tidak menghisap darah. Namun pada musim kawin yang terjadi adalah sebaliknya yaitu nyamuk akan tertarik untuk mendekatinya. Karena itu pilih-pilih saja waktu yang tepat. Oh iya, bila diperdalam lagi mengenai nyamuk maka nyamuk tidak memiliki mata. Mereka berkomunikasi memakai antena yang ada dikepalanya untuk menangkap frekuensi disekitarnya. Selengkapnya bisa disimak pada rangkaian dibawah ini:
Komponen yang diperlukan dari rangkaian diatas adalah N1, N2, N3 = IC4011 dengan transistor tipe NPN biasa. Kemudian C1 = 100mkro Farad, C2=100nf, dan C3=10nf. Nah, silahkan dicoba ya Rangkaian Elektronika Pengusir Nyamuk ini

6. MEMBUAT LAY OUT RANGKAIAN PADA PCB DENGAN TEKNIK PEMINDAHAN TONER
Yang dimaksud teknik pemindahan toner, adalah teknik membuat PCB dengan cara memindahkan gambar lay out atas sebuah rangkaian dari kertas glosi (kertas majalah) ke PCB polos pada sisi tembaga. Gambar lay out atas rangkaian pada kertas glosi pindah ke PCB polos (sisi tembaga) menjadi lay out bawah. Sebetulnya yang berpindah adalah toner-toner yang membentuk gambar lay out atas pada kertas, karena pengaruh pemanasan.
Sedang untuk membuat lay out rangkaian membutuhkan software bantu Eagle 4.11.
Berikut ini adalah cara membuat lay out rangkaian pada PCB dengan teknik pemindahan toner :
1) Cetak lay out atas rangkaian pada kertas majalah (glosi).
2) Gunakan printer toner seperti laser jet. Printer tinta tidak dapat digunakan untuk proses ini. Jika tidak memiliki printer toner, cetak gambar di atas kertas putih, kemudian gambar difoto kopi di atas kertas majalah, atau kalender, atau kertas foto, atau plastik transparan.
3) Untuk membuat lay out atas rangkaian gunakan program bantu seperti Eagle, atau DipTrace, atau PCB Artist.
4) Potong lay out atas yang sudah dicetak pada kertas dengan ukuran tepi 3 mm.
5) Potong PCB polos seukuran lay out atas.
6) Amplas atau kikir bagian tepi PCB polos hingga halus.

8) Keringkan PCB, dan siapkan setrika listrik serta alas kain atau kertas putih.
9) Letakkan PCB diatas alas kain atau kertas polos dengan sisi tembaga menghadap ke atas. Taruh potongan kertas lay out atas rangkaian di atas PCB, dengan gambar menghadap sisi tembaga PCB.
10) Lapisi bagian atas potongan kertas dengan kain atau kertas putih. Agar sewaktu disetrika, gambar pada potongan kertas (majalah) tidak menempel pada setrika.
11) Tekan setrika di atas tumpukan PCB, gambar lay out atas, dan kain (kertas putih) selama 30 detik. Ini dilakukan agar gambar menempel pada sisi tembaga PCB.
Foto oleh Xaveria dan Lenny
12) Gosok setrika hingga merata pada seluruh permukaan PCB, khususnya bagian tepi PCB selama lebih kurang 4 menit.
13) Diamkan PCB hingga termperaturnya kembali normal.
Foto oleh Xaveria dan Lenny
14) Masukkan PCB ke dalam air, rendam lebih kurang 5 menit (untuk kertas majalah); untuk bahan kertas yang lebih tebal seperti kalender atau kertas foto, perendaman lebih kurang 10 hingga 15 menit.
15) Cabut atau lepaskan kertas majalah yang menempel pada PCB. Bersihkan bagian jalur yang masih bersinggungan atau lubang kaki komponen dengan cara digosok-gosok.

15.Rangkaian Speaker Protector sederhana
Speaker Protector sederhanaThis circuit follows will connects the speakers to the power amplifier output only a few seconds after the amplifier is powered ON, so that the speakers do not accept popped up by a high voltage and you would not Hear a loud thud sound from the speakers When the amplifier is switched on. This stuff is very harmful to the speakers.
When the amplifier is powered on the bridge D1 also gets powered through the amplifier’s power switch. Capacitor C1 filters the output of bridge rectifier D1. When the power switch is made ON, the transistor Q1 gets switched ON only after the capacitor C2 is sufficiently charged (0.7V) through the resistor R1. Here the value of C2 and R1 are so selected that the time delay is around 2 seconds. So the relay gets activated only after a few seconds the amplifier is powered ON and until that time the speaker will be kept isolated from the amplifier’s audio output as the speaker is connected to the amplifier’s output through the N/O contact of the relay. During this initial delay period the output of amplifier will be grounded by the resistor R2 through the N/C contact of the relay. This is done in order to ensure that the DC blocking capacitor at the amplifier’s output is charged before it is connected to the speaker.

17. Rangkaian Pendeteksi Angin
This circuit uses an incandescent lamp to detect airflow (mendeteksi angin). With the filament exposed to air, a constant current source is used to slightly heat the filament. As it is heated, the resistance increases. As air flows over the filament it cools down, thus lowering it's resistance. A comparator is used to detect this difference and light an LED. With a few changes, the circuit can be connected to a meter or ADC to provide an estimation on the amount of air flow.

18. Rangkaian Charge Monitor for 12V battery
This circuit project is a function for monitoring the charge level of 12 volt batteries continuously. The circuit possesses two vital features:- reduces the requirement of human attention by about 85%.
- highly accurate and sophisticated methods.
As per manufacturer's data sheets, a 12V rechargeable battery operated Should be within 10. IV and 13.8V. When the battery charges higher than 13.8V it is said to be overcharged, and it discharges below 10.IV Pls Can it be Deeply discharged. A single event of overcharge or deep discharge Can bring down the charge-holding capacity of a battery by 15 to 20%.
Note:
For calibrating the upper and lower reference levels, a digital multimeter and a variable regulated power supply source are required. For calibrating the lower reference voltage, follow the steps given below:
- Set the output of power supply source to 10. IV.
- Connect the power supply source in place of the battery.
- Now the display will show some reading. At this point vary preset VR2 until the reading on the display just changes from 1 to 0.
- The higher reference voltage is calibrated similarly by setting the power supply to 13.8V and varying preset VR1 until reading on the display just changes from 8 to 9.
How to Work a Circuit of Charge Monitor for 12V Battery
Input from the battery under test is applied to LM3914 1C. This applied voltage is ranked anywhere between 0 and 10, depending upon its magnitude. The lower reference voltage of 10.IV is ranked '0' and the upper voltage of 13.8V is ranked as '10.' (Outputs 9 and 10 are logically ORed in this circuit.) This calibration of reference voltages is explained above.
1C 74LS147 is a decimal-to-BCD priority encoder which converts the output of LM3914 into its BCD complement. The true BCD is obtained by using the hex inverter 74LS04. This BCD output is displayed as a decimal digit after con version using IC5 (74LS247), which is a BCD-to-seven-segment decoder/driver. The seven-segment LED display (LTS-542) is used because it is easy to read compared to a bar graph or, for that matter, an analogue meter. The charge status of the battery can be quickly calculated from the display. For instance, if the display shows 4, it means that the battery is charged to 40 per cent of its maximum value of 13.8V.
The use of digital principles enables us to employ a buzzer that sounds whenever there is an overcharge or deep discharge, or there is a need to conserve battery charge. A buzzer is wired in the circuit such that it sounds whenever battery-charge falls to ten per cent. At this point it is recommended that unnecessary load be switched off and the remaining charge be conserved for more important purposes.
Another simple combinational logic circuit can also be designed that will sound the buzzer when the display shows 9. Further charging should be stopped at this point in order to pre vent overcharge
19. Rangkaian Magnetic proximity sensors
Here is the circuit diagram of a magnetic proximity switchsensor which can be used in various applications. The circuit is based on a magnetic reed switch as the proximity sensor. A monostable multivibrator based on NE555 and a toggle flip flop CD4013 does the rest of the circuit.
magnetic reed switch sensor
The magnetic proximity switch sensor circuit, in principle, consists of a reed switch at its heart. When a magnet is brought in the vicinity of the reed switch it operates and controls the rest of the switching circuit. In place of the reed switch, one may, as well, use a general-purpose electromagnetic reed relay as the sensor, if required. These tiny reed relays are easily available as they are widely used in telecom products. The reed switch or relay to be used with this circuit should be the normally open type.When a magnet is brought in the vicinity of the sensor element for a moment, the contacts of the reed switch close to trigger timer IC1 wired in monostable mode. As a consequence its output at pin 3 goes high for a short duration and supplies clock to the clock input (pin 3 CD4013). LED D2 is used as a response indicator.
This CMOS IC2 consists of two independent flip-flops though here only one is used. Note that the flip-flop is wired in toggle mode with data input (pin 5) connected to the Q (pin 2) output. On receipt of clock pulse, the Q output changes from low to high state and due to this the relay driver transistor T1 gets forward-biased. As a result the relay RL1 is energised.

21. Rangkaian Indikator Suhu Air.
Indikator Suhu AirThis is a circuit that serves to indicate various levels of hot water in a tank. SW1 is a normally open press button switch which allows you to view the level of hot water in a hot water tank. When pressed the voltage difference at the junction of the thermistor and preset is compared to the fixed voltage on the op-amps non-inverting input. Depending on the heat of the water in the tank, the thermistors resistance will toggle the op-amp output to swing to almost full voltage supply and light the appropriate LED.
Note:
- Op-Amp: LM324 or any quad opamp can be used or even four single op-amps.
- R2-R5: 330ohm resistors, but Lower values give brighter LED output.
- NTC1-4: Cold resistance was around 300K, hot resistance 15k. Alternative thermistors may be used with different resistance ranges, but the presets P1 to P4 must also be changed as well.
- R7-10: only required if your thermistors resistance is several ohms at the hottest temperature.
- P1 - P4: Chosen to match the resistance of the thermistor when cold.
- R1 & R6: 100k Resistor
Masking tape was used to stick the bead thermistors to the tank. Wires were soldered and insulated at the thermistors ends. A plastic box was used to house the circuit. Battery life will probably be 4 to 5 years depending on how often you use the push switch, SW1.
Thermistors NTC1-4 should be spread evenly over the height of the tank. I placed NTC1 roughly 4 inches from the top of my tank and the others were spaced evenly across the height of the hot water tank. As hot water rises the lowest sensor indicates the fullest height of hot water and should be about 8 to 10 inches from the bottom of the tank.
With a full tank of hot water adjust P1-4 so that all LED's are lit. As hot water rises, the sensor at the bottom of the tank will be the maximum level of hot water. 'Hot' can be translated as 50C to 80C the presets P1-4 allow adjustment of this range.
22. Rangkaian Speedometer Digital
Speedometer DigitalThis circuit serves to show the speed of the vehicle in kmph. An opaque disc is mounted on the spindle attached to the front wheel of the vehicle. The disc has about equidistant holes on its periphery. On one side of the disc an infrared LED is fixed and on the opposite
side of the disc, in line with the IR LED, a phototransistor is mounted. IC LM324 is wired as a comparator. When a hole appears between the IR LED and phototransistor, the phototransistor conducts. Hence the voltage at collector of the phototransistor and inverting input of LM324 go ‘low’, and thus output of LM324 becomes logic ‘high’. So rotation of the speedometer cable results in a pulse (square wave) at the output of LM324. The frequency of this waveform is proportional to the speed.

For a vehicle such as LML Vespa, with a wheel circumference of 1.38 metres, and number of pulses equal to 10 per revolution, we get the relationship:
This speedometer can measure up to 99 kmph with a resolution of 1 kmph. The range can be increased up to 999 kmph by adding another stage consisting of one each of ICs 7490, 74175, 7447 and a 7-segment display
23. Rangkaian pengukur jarak Digital
Pengukur jarak DigitalThis circuit measures the distance covered during a walk. Hardware is located in a small box slipped in pants' pocket and the display is conceived in the following manner: the leftmost display D2 (the most significant digit) shows 0 to 9 Km. and its dot is always on to separate Km. from hm. The rightmost display D1 (the least significant digit) shows hundreds meters and its dot illuminates after every 50 meters of walking. A beeper (excludable), signals each count unit, occurring every two steps.
Skema Rangkaian pengukur jarak Digital
Note:
- Experiment with placement and sloping degree of mercury switch inside the box: this is very critical.
- Try to obtain a pulse every two walking steps. Listening to the beeper is extremely useful during setup.
- Trim R6 value to change beeper sound power.
- Push P1 and P2 to reset.
- This circuit is primarily intended for walking purposes. For jogging, further great care must be used with mercury switch placement to avoid undesired counts.
- When the display is disabled current consumption is negligible, therefore SW3 can be omitted.
A normal step was calculated to span around 78 centimeters, thus the LED signaling 50 meters illuminates after 64 steps (or 32 operations of the mercury switch), the display indicates 100 meters after 128 steps and so on. For low battery consumption the display illuminates only on request, pushing on P2. Accidental reset of the counters is avoided because to reset the circuit both pushbuttons must be operated together. Obviously, this is not a precision meter, but its approximation degree was found good for this kind of device. In any case, the most critical thing to do is the correct placement of the mercury switch inside of the box and the setting of its sloping degree.
24. Rangkaian Sensor Pendeteksi Warna
Sensor Pendeteksi WarnaThis circuit can sense eight colours, i.e. blue, green and red (primary colours); magenta, yellow and cyan (secondary colours); and black and white. The circuit is based on the fundamentals of optics and digital electronics. The object whose colour is required to be detected should be placed in front of the system.
Skema Rangkaian Sensor Pendeteksi Warna
Note:
- Potmeters VR1, VR2 and VR3 may be used to adjust the sensitivity of the LDRs.
- Common ends of the LDRs should be connected to positive supply.
- Use good quality light filters.
The light rays reflected from the object will fall on the three convex lenses which are fixed in front of the three LDRs. The convex lenses are used to converge light rays. This helps to increase the sensitivity of LDRs. Blue, green and red glass plates (filters) are fixed in front of LDR1, LDR2 and LDR3 respectively. When reflected light rays from the object fall on the gadget, the coloured filter glass plates determine which of the LDRs would get triggered. The circuit makes use of only AND gates and NOT gates.
When a primary coloured light ray falls on the system, the glass plate corresponding to that primary colour will allow that specific light to pass through. But the other two glass plates will not allow any light to pass through. Thus only one LDR will get triggered and the gate output corresponding to that LDR will become logic 1 to indicate which colour it is. Similarly, when a secondary coloured light ray falls on the system, the two primary glass plates corres- ponding to the mixed colour will allow that light to pass through while the remaining one will not allow any light ray to pass through it. As a result two of the LDRs get triggered and the gate output corresponding to these will become logic 1 and indicate which colour it is.
When all the LDRs get triggered or remain untriggered, you will observe white and black light indications respectively.
The LDR is mounded in a tube, behind a lens, and aimed at the object. The coloured glass filter should be fixed in front of the LDR as shown in the figure. Make three of that kind and fix them in a suitable case. Adjustments are critical and the gadget performance would depend upon its proper fabrication and use of correct filters as well as light conditions.

This is a simple wind meter (anemometer) circuit. this circuit can measure wind speeds up to 75m/s using this circuit.
Transistors Q1 and Q2 are used for sensing the wind. The relationship between thermal impedance of the transistor and the surrounding wind speed is utilized here. Transistors Q1 and Q2 are wired so that the Vce of Q1 is higher than Q2 and therefore there will be a higher power dissipation. The wind causes cooling and so the Vce of Q1 changes. The ends in different power dissipations and different voltages across R10. This variation is detected by the opamp and amplified to produce the Vout which is proportional to the wind speed. For still air Vout will be 0V and at 75m/s wind speed the Vout will be 2.5V. A 3V FSD voltmeter connected across the Vout terminal and ground can be used as the display.
For proper working, the air must pass over both the transistors (Q1 and Q2).
The resistors used are not standard values. So you need to use the combination (series or parallel) of resistors to attain the specified values. Please note that the resistor values are very critical in this circuit.

IC CS209A Description
The CS209A is a bipolar monolithic integrated circuit for use in metal detection (Pendeteksi Metal)/ proximity sensing applications. The IC (see block diagram) contains two on-chip current regulators, oscillator and low-level feedback circuitry, peak detection/demodulation circuit, a comparator and two complementary output stages.
The oscillator, along with an external LC network, provides controlled oscillations
where amplitude is highly dependent on the Q of the LC tank. During low Q conditions, a variable low-level feedback circuit provides drive to maintain oscillation. The peak demodulator senses the negative portion of the oscillator envelop and provides a demodulated waveform as input to the comparator. The comparator sets the states of the complementary outputs by comparing the input from the demodulator to an internal reference. External loads are required for the output pins. A transient suppression circuit is included to absorb negative transients

This is a photocell circuit for detecting the light intensity. At full light the resistance of the photocell will be few ten ohms and at darkness it will rise to several hundred ohms. IC1 Op amp uA741 is wired as a comparator here. At darkness the resistance of photocell increases and so the voltage at the inverting input of the IC1 will be less than the reference voltage at the non inverting input. The output of the IC1 goes to positive saturation and it switches ON the transistor to activate the relay. By this way the lamp connected through the relay contact glows. The diode D1 works as a freewheeling diode.
Rangkaian Lampu otomatis menggunakan photocell (LDR)
photocell
A light sensor (photodetector) that varies its resistance between its two terminals based on the amount of photons (light) it receives. Used for photographic light meters, automatic on-at-dusk street lights and other light-sensitive applications, it is also called a 'light dependent resistor' (LDR) and 'photoresistor.'
The photocell's semiconductor material is typically cadmium sulfide (CdS), but other elements are also used. Photocells and photodiodes are used for similar applications; however, the photocell passes current bi-directionally, whereas the photodiode is unidirectional.
Photocells come in a variety of packages such as this assortment from PerkinElmer. As the photocell receives more photons, the resistance is lowered between the two terminals.

A low-cost circuit described here can be used to switch off any gadget automatically in case of excessive humidity. At the heart of the circuit is an inexpensive (resistor type) dew sensor element. Although dew sensor elements are widely used in video cassette players and recorders, these may not be easily available in local market. However, the same can be procured from authorised service centres of reputed companies. The author used the dew sensor for FUNAI VCP model No. V.I.P. 3000A (Part No: 6808-08-04, reference no. 336) in his prototype. In practice, it is observed that all dew sensors available for video application possess the same electrical characteristics irrespective of their physical shape/size, and hence are interchangeable and can be used in this project.
Skema Rangkaian Pendeteksi (Sensor) Kelembaban Udara
The circuit is basically a switching type circuit made with the help of a popular dual op-amp IC LM358N which is configured here as a comparator. (Note that only one half of the IC is used here.) Under normal conditions, resistance of the dew sensor is low (1 kilo-ohm or so) and thus the voltage at its non-inverting terminal (pin 3) is low compared to that at its inverting input (pin 2) terminal. The corresponding output of the comparator (at pin 1) is accordingly low and thus nothing happens in the circuit. When humidity exceeds 80 per cent, the sensor resistance increases rapidly. As a result, the non-inverting pin becomes more positive than the inverting pin. This pushes up the output of IC1 to a high level. As a consequence, the LED inside the opto-coupler is energised. At the same time LED1 provides a visual indication. The opto-coupler can be suitably interfaced to any electronic device for switching purpose. Circuit comprising diode D2, resistors R5 and R6 and capacitor C1 forms a low-voltage, low-current power supply unit. This simple arrangement obviates the requirement for a bulky and expensive step-down transformer.

When water is rising the the base of each transistor gets electrical connection to 6V AC through water and the corresponding probe. Which in turn makes the transistors conduct to glow LED and indicate the level of water. The ends of probes are connected to corresponding points in the circuit as shown in circuit diagram. Insulated Aluminum wires with end insulation removed will do for the probe. Arrange the probes in order on a PVC pipe according to the depth and immerse it in the tank.

You can also listen to your television set at a very low volume, avoiding to bother relatives and neighbors. Even if you have a faultless hearing, you may discover unexpected sounds using this device: a remote bird twittering will seem very close to you.
The heart of the circuit is a constant-volume control amplifier. All the signals picked-up by the microphone are amplified at a constant level of about 1 Volt peak to peak. In this manner very low amplitude audio signals are highly amplified and high amplitude ones are limited. This operation is accomplished by Q3, modifying the bias of Q1 (hence its AC gain) by means of R2.

All signal processing is done within the TDA1524A by voltage controlled amplifiers and voltage controlled filters. The IC provides a fixed voltage (~ 3.8V DC) at pin 17, and this is used by all the variable resistors to provide an adjustable DC voltage to the appropriate control pins.
Current sensing is used to provide a flat response when R5 is connected to pin 17, and a loudness contour when disconnected. 100 nF capacitors are used on each pot to decouple any AC signals from the control inputs. 10 uF capacitors are used to couple both input and output audio signals whilst blocking DC. R1 and R2, are to ensure stability with capacitive loads. R3 and R4 make sure there are no DC spikes at the output sockets if the load is switched. C3 and C4 control the loudness contour. C5 and C6 control the treble turn-over frequency. C18 and C19 have been added to roll off the gain above 70 kHz. Low volume settings coupled with treble boost was causing HF instability in some instances. This should no longer be a problem.

Low volume settings coupled with treble boost was causing HF instability in some instances. This should no longer be a problem.
C15, 16, 17 provide power supply filtering. D1 provides protection in case of incorrect supply polarity. The LED is a power on indicator and may be omitted if not required, or preferably mounted on the enclosure. If you are not using a switch pot, you can connect an external switch across the P1 switch pins, or connect a wire link there and switch the power supply.
The power supply is critical to the noise performance of the pre-amp head. An on board regulator is provided to reduce mains hum. If you wish to use it with a car or other 12V battery, then you should omit the 7812 regulator, and place a wire link between the regulator input and output pin positions on the PC board. Do not short to earth! This will be necessary because the regulator must have an input voltage at least 2-3V greater than it’s output, for it to maintain regulation. However the regulator will not be necessary with a battery supply.
If using a plug pack, it’s output voltage should be 15 to 18V DC. Because most plug packs have poor regulation, one rated at 12V DC will often be around 15V when lightly loaded. The current drain of the pre-amp is less than 50 mA, so many 12 V unregulated supplies may be adequate if you have one. Replace D1 with a wire link if necessary, making sure you have the supply polarity correct!
If you are using a 15-20V supply for your power amplifier, you can use that as your pre-amp supply as well. Make sure you test the voltage first in all cases.
