Song Music generator circuit using ic UM66

This is a simple (song) music generator circuit using ic UM66. To make a musical calling-bell, door-bell, kids toys etc. we can use this funny audio/sound/music/tone generator ic UM66. The UM66 series are CMOS IC’s, they has a built in ROM to store the music. The IC operates in DC +3V. We suggest to use two dry cell (1.5V X 2) for +3V Supply.  For Q1 use a TO-92 type NPN transistor like BC548, BC168, BC183, BC238, 2N2222. Speaker must be 4Ω or higher.

Build a High Voltage Dc Generator Wiring diagram Schematic

High Voltage Dc Generator Circuit Diagram. In the miniature high-voltage dc generator, the input to the schema, taken from a 12-Vdc power supply, is magnified to provide a 10,000-Vdc output causing a pulsating signal, of opposite polarity, to be induced in Tl`s secondary winding. 

The pulsating dc output at the secondary winding of Tl (ranging from 800 to 1000 V) is applied to a 10-stage voltage-multiplier schema, which consists of D1 through D10, and C3 through C12. The multiplier schema increased the voltage 10 times, producing an output of up to 10,000 Vdc. The multiplier accomplishes its task by charging the capacitors (C3 tlirough C12); the output is a series addition of the voltages on all the capacitors in the multiplier. In order for the schema to operate efficiently, the frequency of the square wave, and therefore the signal applied to the multiplier, must be considered. 

The output frequency of the oscillator (Ul-a) is set by the combined values of Kv Rr>, and C{ (which with the values specified is approximately 15 kHz). Potentiometer R5 is used to fine tune the output frequency of the oscillator. The higher the frequency of the oscillator, the lower the capacitivc reactance in the multiplier. Light-emitting diode LED1 serves as an input-power indicator, and neon lamp NE1 indicates an output at the secondary of Tl. A good way to get the maximum output at the multiplier is to connect an oscilloscope to the high-voltage output of the multiplier, via a high-voltage probe, and adjust potentiometer R5 for the maximum voltage output.

High Voltage Generator Wiring diagram Schematic

This is a short  High Voltage Generator Circuit Diagram of a high voltage generator and can be mounted in a small space and powered by rechargeable or simple batteries, the schema generates a voltage low current but a high turn-on of about 200 to 400 V harmless to humans, of course, but is able to give a pretty nasty shock. 

 High Voltage Generator Circuit Diagram

 high voltage generator circuit diagram


Here is a project that could be useful this summer on the beach, to prevent anyone touching your things left on your beach towel while you was swimming, you can equally well use it in the office or workshop when you return to work. It operates as a low frequency oscillator, which makes it possible to convert the battery voltage into a DC voltage alternating current that can be enhanced through the transformer. 

Using a transformer with center tap as herein makes possible the construction of a Hartley oscillator transistor T1 around The output voltage can be used directly through R2 and R3 current limiting resistors, which should not in any circumstances be omitted or modified, they are what make the schema have security. You will then get about 200 V peak-to-peak, which is already quite unpleasant to the touch. 

But you can also use a voltage doubler, shown at the bottom right of the figure, which will produce about 300 V, even more unpleasant to the touch. Here too, of course, the resistance, you know how R4 and R5, should always be present. It can be used in small electric fences, chase away animals, etc.

WACKER NEUSON Generator TROUBLESHOOTING

WACKER NEUSON Generator _  How to check voltage at plug – voltage at generator terminals strip
TROUBLESHOOTING
  If a generator problem is not an obvious engine or wire fault, the cause of  the  problem  will  be  associated  with  one  of  two  things:
  A malfunctioning generator or faults in the schema supplying voltage to the receptacles.  By  starting  the  troubleshooting  procedures  at  the generator output terminal strip (z) you can determine whether the problem  lies  within  the  generator  or  the  schema  supplying  the receptacles.  For troubleshooting a no-voltage condition, you’ll need to rule out problems with the stator windings (1) and the rotor windings (13). For a low-voltage condition (any voltage less than 120V), you’ll need to rule out problems with the stator and rotor windings, a malfunctioning voltage regulator (16), and problems with the brushes (13) and/or the excitation winding (15). For a high-voltage condition, you’ll need to rule out a malfunctioning voltage regulator and/or problems with the voltage regulator’s sensing wires (y).
  For troubleshooting the receptacle diagram, you’ll need to rule out problems  with  the  main  schema  breaker  (3),  the  individual  schema breakers  (5,  6,  and  7),  and  the  wiring  that  connects  all  the components.  For troubleshooting a malfunctioning auto idle schema, you’ll need to rule out a blown fuse (9) and problems with the idle solenoid, the DC winding (15), the rectifier (12), the auto idle switch (8), the auto idle unit (2), and the wiring that connects all the components.  For troubleshooting a malfunctioning anti-after fire schema, you’ll need to rule out a faulty DC winding (15), a blown fuse (9), a faulty engine ON/OFF switch (11), or a faulty capacitor (10).
Checking Continuity
Conduct continuity tests when the engine is shut down.  When checking continuity, use the Ohm setting on your multimeter.  Place a lead of the multimeter on one end of the wiring or component and the other lead on the opposite end. If your meter reads “OL” or “OPEN”, there is no continuity and the wiring or component must be repaired or replaced.
Note:  Some multimeters also have an audio signal setting for determining continuity. This setting may also be used.
If  your  meter  reads  less  than  1.0  Ohm,  or  the  audio  signal sounds, the wiring or component has continuity and should be OK.
If your meter reads more than 1.0 Ohm, the wiring is faulty and must be repaired or replaced.
Checking Resistance
Conduct resistance checks when the engine is shut down.  Use the Ohm setting on your multimeter.  Conduct resistance checks when the machine is as close to 21°C (70°F) as possible. Higher temperatures can affect resistance values.  Most digital multimeters have some internal resistance. To obtain your
multimeter’s internal resistance, simply cross the two leads of your multimeter and read the display. When conducting a resistance check, subtract  your  multimeter’s  internal  resistance  from  the  value  you measure to obtain the true resistance of the component you are checking
Checking Voltage
Conduct voltage checks when the engine is running.  Use the Volt setting on your multimeter. To prevent damage to your instrument, start with the highest scale available on your multimeter.  Adjust to a lower scale as readings dictate.  Use extreme caution when checking voltage to reduce the risk of
electric shock.
Checking Voltage at Generator Terminal Strip
Remove the two screws (a) that secure the end cover to the generator and remove the end cover.
Start the engine.
Using the AC voltage setting on the multimeter, measure the voltage between the wire with the yellow marking (b) and the wire with the red marking (c). There should be 120V±10%. [If zero (0) volts is measured, it indicates a problem with main winding 2 or the rotor winding.  If 120V±10% is measured, main winding 2 and the rotor are functioning; continue]
Using the AC voltage setting on the multimeter, measure the voltage between the wire with the green marking and the wire with the black marking. There should be 120V±10%. [If zero (0) volts is measured, it indicates a problem with main winding 1.  If 120V±10% is measured, main winding 1 and the rotor are functioning; any problems with the receptacles receiving voltage are in the schema to the receptacles.]
Checking Voltage at Plug - GP 2500A, GP 2600
By starting the troubleshooting procedures at the generator output plug (d), you can determine whether the problem lies within the generator or the schema supplying the receptacles. To check the voltage at the output plug, carry out the following procedures:
Remove the two screws which secure the end cover to the generator and remove the end cover.
Start the engine.
Using the AC voltage setting on the multimeter, measure the voltage between the red wire and the white. There should be 120V±10%. [If zero (0) volts is measured, it indicates a problem with main winding 2 or the rotor winding.  If 120V±10% is measured, main winding 2 and the rotor are functioning; continue.]
Using the AC voltage setting on the multimeter, measure the voltage between the brown wire and the blue wire.  There should be 120V±10%  [If zero (0) volts is measured, it indicates a problem with main winding 1.  If 120V±10% is measured, main winding 1 and the rotor are functioning; any problems with the receptacles receiving voltage are in the schema to the receptacles]

Pulse generator circuit with Logic Gate

Pulse generator circuit above is a pulse generator that uses logic gates. There are so many types and variations that can generate a series of pulses.
The simplest is the use of transistors or often called a flip-flop. There also are using integrated circuit such as IC 555. Theres more to exploit the resonance of the capacitor and inductor relationship as oscillators. To be sure whatever form and whatever the circuit components used must be able to generate electric waves which have a peak voltage (logic 1) and valleys (logic 0) is continuous.



Any variation of pulse generator circuit design has advantages and disadvantages of each, just how your decision for the appropriate circuit. For example to create a clock signal for a simple utility that you can only take advantage of the transistor but if you need a more accurate clock signal and form a perfect balance you can use IC Astable or logic gates. Or perhaps you need a signal with very high frequency (up to MHz) you can use a combination of inductor, resistor and capacitor.

Frequency value of the pulse generator circuit gate above is determined by the value kapaitor C2, R2, R3 and VR2. The greater the value of these components will lower the frequency and vice versa. Actually nothing is difficult to make a series of pulse generators, almost all time-based series is utilizing the nature of the charge and discharge capacitor. Therefore, like any form of variations in pulse generator circuit, always have a larger capacitor value will make the frequency produced smaller or longer periods of time, sedangkaan smaller capacitor values ​​will result in greater output frequency.

Luminescent Generator

Luminescent Generator Circuit diagram. When spun rapidly between the fingers, a bipolar stepper motor will generate around 10VAC. If this is stepped up with a small 240V to 6-0-6V transformer in reverse (with series connected secondaries), a small bipolar stepper motor is capable of powering a standard 5cm by 6cm luminescent sheet at full brightness. These are designed to be powered from 20V to 200VAC (typically 115VAC), producing 1.5 candelas of light - which will dimly light the average room, or adequately light a camp table. They are manufactured by Seikosha (RS Components Cat. 267-8726).

Luminescent Generator Circuit diagram:
luminescent-generator-schema
Luminescent Generator Circuit Diagram

The transformer should be a small one (around 100mA or so), otherwise efficiency is compromised. The wires of the motors two phases are usually paired white & yellow and red & blue. Just one of these phases is employed in the schema. If a small bipolar stepper motor from a discarded 3.5-inch disk drive is used, the Luminescent Generator may be built into a very small enclosure. To sustain rapid, smooth spinning of the motor, a geared handle may be added.
