Troubleshooting STR IC Regulator Power Supply
A. Unable to start.
Can be caused by:
- No start-up voltage supply Vcc or a voltage less than 16V
- Electrolityc Capacitors supply voltage Vcc filter dry.
2. Led indicator blinking
If the supply voltage Vcc examined rocking. This is because the regulator of life and death because OVLO work., Die-protectionist regulators and auto start life over and over. If it is turned off Electrolityc Capacitors usually still keep the rest of the cargo.
Can be caused by:
- Electrolityc Capacitors supply voltage Vcc filter on a pin-4 dry. Replace with a value equal to or slightly larger. - triger UVLO
- input filter capacitor on pin-1 feed dry behind the declining value - triger OLP
- Rectifier diode of the switching transformer is damaged (sometimes when examined with avo-meter looks like a still good)
- cause the supply voltage Vcc drops of the switching transformer (UVLO)
- Part damage or broken lines on the feedback circuit of the voltage regulator through B to photocoupler - triger OVP
- Electrolityc Capacitors dry filter voltage B - triger OVP
- One of the output voltage of the switching transformer secondaries there is a short (over load) - triger OLP
- Soft start capacitor value decreases - triger OLP
3. Noise arising (noise)
Can be caused by:
- Transformer windings slack.
- If there are ceramic capacitors - can sometimes cause interference noise due to its characteristic piezoelectrik like crystal resonator. Replace with film capacitors.
4. When the st-by normal stress. But when the power is on the regulator directly off protectionism no voltage on the secondary this part. Electrolityc Capacitors are still storing charge.
Can be caused by:
- Sensor OVP small value resistor on pin-2 to the ground so that the value of delayed triger to OLP or OCP.
- Regulator IC is damaged
---------------------------------------------------------------------------------------------------------------------------
Note: Be careful when the regulator is not working. Because of Electrolityc Capacitors may still have a charge when turned off.

Police Sirine Circuit with IC 555
The series of police sirens with 555 ic this is a series of sirens that utilizes two IC 555 as a pulse generator and producing shrill voice.
Both ic 555 respectively build the astable multivibrator circuit and generate output signals with different frequencies. It is intended to be used as one of the high frequency generator or a screeching sound and the other as a regulator of the swing from last shrill voice. If we observe the working principle of this circuit is very similar to a series of modulation fm. Where the shrill sound signal likened to a high frequency signal from the oscillator circuit and control signal swing is the wail of the information signal or input signals that will transmit. This is consistent with the shape of the output signal associated with the loudspeaker, which has an output signal frequency changes in the form of regular meetings wave tenuous.
Actually a series of sirens could be simpler than if you use a 556 IC which is a dual multivibrator or equal to two pieces of IC 555. IC 556 has two multivibrator circuit menfaatkan so you can meet the workflow of this siren sound-producing circuit. Or you can also make it by using a combination of multiple transistors. And it could be you do remember the oscillator circuit can be easily made with transistors.
Appropriate image above then:
R1, R2, and C1 is a determinant of the frequency of the signal generated by IC1
R3, R4 and C3 is a determinant of the signal frequency whine
Signals generated by IC1 IC2 pin 5 connected to the control signals intended for the resulting shrieks
Screeching sound signal will swing to follow the control of the output signal IC1
You can do experiments in order to gain more understanding of police sirens this circuit by changing the value of some critical components such as the frequency of R1, R2, R3, R4, C1 and C3.

Vertical IC Configuration
Various kinds of vertical out IC configuration. Ac coupling -connect from the yoke deflection output to a coil connected directly. Dc coupling - connected the output to the coil through a capacitor deflectioan yoke. Electrolityc Capacitors (usually worth 1000u/35v). This configuration requires two kinds of voltage (the voltage mirror plus-minus). Dc input coupling using diffferential - uses 2 input from the driver IC.

LM3914 IC based on Simple Battery Tester
This circuit employs the popular and easy to find LM3914 IC. This kind of IC is quite very simple to drive, requires no voltage regulators (it features a built in voltage regulator) and can be powered from almost every resource.This LM3914 IC based on Simple Battery Tester is very simple to explain:
Once the test switch is pushed, the Car battery voltage is supply into a high impedance voltage divider. His function is to divide 12V to 1, 25V (or lower values to reduced values). This solution is much better than enabling the internal voltage regulator set the 12V sample voltage to be feed into the internal voltage divider simply because it cannot regulate 12V if the voltage falls lower (linear regulators only step down). Simply wiring with no change, the regulator provides secure 1, 25V which can be fed into the precision internal resistor cascade to create sample voltages to the internal comparators.
In any case the default establishing let you to determine voltages between 8 and 12V however you can measure even from 0V to 12V setting the offset trimmer to 0 (but i believe that below 9 volt your vehicle would not start). There is a smoothing capacitor (4700uF 16V) it is used to adsorb EMF noises produced from the ignition coil if youre testing the battery during the engine working. Diesel engines would not need it, but i am not sure. If you want more a level graph rather than a bar graph simply disconnect pin 9 on the IC (MODE) from power. The calculations are usually simple (default).

USB SPDIF DAC with IC PCM 2902
The tool that I made and I discuss in this article I give the name USB SPDIF DAC Every word in the name corresponds to the function of the tool that I made this.
USB, this device serves to take the music information in digital form from a computer via the USB port
SPDIF, this tool can output digital music information received through the USB port, through the SPDIF output terminal that is also present in this device, so if you have a DAC that does not have a USB input, you can still use and do not need to buy a new DAC that has an input USB.
DAC, this tool can convert the digital signals derived from the USB port, an analog signal, which you can connect to the amplifier to the ahirnya you can hear the speaker
Scheme of the USB DAC can be seen in Figure 1 below.USB, this device serves to take the music information in digital form from a computer via the USB port
SPDIF, this tool can output digital music information received through the USB port, through the SPDIF output terminal that is also present in this device, so if you have a DAC that does not have a USB input, you can still use and do not need to buy a new DAC that has an input USB.

| Click to view larger. | Figure 1 |
As you can see on the schematic in Figure 1 above, which is the heart of the circuit is IC USB DAC PCM2902 made by Texas Instrument, other than that I also added a digital SPDIF output isolation transformer on from this series. 2902 PCM encoding decoding work on the principle that generally abbreviated as word CODEC.
The new circuit will work when the USB input port terminal in the circuit connected to the computer, at this voltage 5V on the USB port of any computer will be triggering the circuit to begin work, and vice versa when the computer is turned off then the circuit will be in standby mode to wait until there is more tension 5V from USB port of computer.
When the received voltage is 5V USB port the computer then the circuit will begin to receive the digital data files during the grace period of 1 ms, all data received during the period of time of 1 ms is called a frame, the data in the first frame is stored in a memory buffer that is in the PCM2902, then the circuit will start the second frame as well as long lead times for 1mS, 1mS a second after the first data from the file will be converted into analog signals for analog terminal is then removed through out the pin 15 and 16 of the PCM2902, other than that this digital signal simultaneously will also excreted through the DOUT terminal pin 25 of the PCM2902 DAC to be connected to older products that do not have a USB input terminal. In addition to functioning as a DAC, PCM2902 actually also has other functions such as setting volume level and ADC, but the circuit that I developed is only aimed for the ADC and the conversion from USB to SPDIF.
Proposed Power Supply For USB SPDIF DAC
Power Supply that I use in this project using the configuration has been proven able to tame the hum in the tube 26, the power supply has karakater very stable, low noise and low impedance, but complicated to make, so for the purposes of this project I recommend another series that is not as complicated Heater power supply 26, but the quality is still better than most of the power supply kit used in the DAC in general, Figure 2 below is the recommendation power supply for USB DAC this project.

1. Diode bridge and capacitor input filter
2. TL431 as the reference voltage
3. OP Amp OP27 as the error amplifier
4. BD139 transistor as a pass transistor This configuration is basically the general configuration of a linear regulator series, very much the regulator IC using this configuration, but the circuit in Figure 2 above has several advantages that are not owned by the regulator circuit in the form of IC a) high stability, since it uses a reference voltage source of good quality is TL431, and therefore not in a package with a pass transistor, the heat of the pass transistor can not seep into the source of reference voltage and makes it unstable, this sort of thing happens in IC voltage regulator. b) Using the Op Amp high quality, which in this case OP27, so it is not easy to oscillate as the OpAmp used in the regulator IC. c) If there is a chance you could also replace the TL431 or OP27 Op Amp voltage source and another that is expected to be better than either of these components.
