Component Parts

• NE555
• Capacitors
• Resistors
• Transistor
• Variable resistors
• EHT Transformer

Description

The electronic circuit design like in Figure 1 above show you high voltage generator using NE555 IC for you. 

According Circuitstoday blog mentioned that this is first of all let me remind you that this circuit is a very dangerous one. The output voltage of this circuit is in Kilo volts and it can seriously injure you or kill you. Try this circuit only if you have enough experience dealing with high voltages. I have no responsibility on any hazards caused by the circuit. Be very careful. This is a humble request.

The circuit given here has three sections namely oscillator, switching stage and a step up stage. The oscillator is build around a NE555 timer operating at 25 KHz. The output of the NE555 coupled to the base of the power transistor TIP3055 which is the switching device. The power transistor drives primary of the step up transformer at 25 KHz and as a result a high voltage will be induced across its secondary.

Description

The electronic circuit design like in Figure 1 above show you wind sound generator circuit using transistors. Other component need also that can supply with low voltage DC 9V source to charge this transistor and all system component. With this electronic design circuit you can produce wind sound generator that useful now.

According ElectronicProjects blog mentioned that using this simple circuit, one can generate the sound of wind. The circuit is basically an astable multivibrator build around two NPN transistors.
By adjusting the 1M potentiometer (VR1), the sound can be changed from that of wind to storm, sound of sea, hiss of escaping gas from a container through a small hole etc. A 9-Volt or 6-volt unregulated power supply is enough. How-ever, a battery may be used instead. The output sound will be slightly changed. The prototype has been successful tested with the given power supply. Also and 8-ohm, 5cm, low wattage speaker is recommended.

Electronic Design: Sine Wave Converter Circuit using NE555 IC

Wave Generator Circuit. - There are many electronic circuit designed to build wave generator or converter. This is aim to result many kinds wave source like sine, pulse, and square. One pupular wave in electronic design is sine wave for many application. So, in here we will present you one electronic circuit design to result sine wave using popular component that called with 555 IC.

Beside we will show you electronic design circuit and component parts need, we also will give you global description about this circuit. So, please enjoy to continue reading this article until finish and get more useful.

Component Parts

• R1, R2 110K ohm 5% 1/4W Carbon Film Resistor
• R3 4.7K ohm 5% 1/4W Carbon Film Resistor
• C1 0.01uF/25V Ceramic Capacitor
• E1 1uF/25V Electrolytic Capacitor
• U1 555 Timer IC

Description

The electronic circuit design like in Figure 1 above show you sine wave converter circuit using the major component called with NE555 IC. In here we can use 12V source to charge this IC. The timer of 555 IC is configured as a Schmitt trigger principle. To result output square wave, it is do by applying the input sine wave signal with connecting trigger input pin 2 and threshold input pin 6 of the timer together.

According ElectronicsProjectDesign blog mentioned that this circuit is achieved because once the input signal is above 2/3 X 12V = 8V DC, the output 3 voltage will become low (< 1V DC). The output voltage will remain low until the input signal go down to below 1/3 X 12V = 4V DC. When this threshold is achieved, the output will go high (>10V DC).

It will remain high until the input signal voltage level reaches 8V when it will switch back to low. This type of switching continues on hence by applying a sine wave input, you will get a square wave output. 

The difference of voltage 8V-4V is 4V which is the hysteresis. This hysteresis value is necessary to ensure proper signal conditioning in the presence of electrical noises in the circuit. The capacitor E1 is used to remove the DC component of the input signal that may be present. Resistors R1 and R2 are used as voltage divider to divide the quiescent voltage of 6V.

There are many instances where you will need to convert a sine wave signal to square wave signal as many input ports of semiconductor devices are triggered by rising or falling of clock signal.
