Electronic Candle Blow Out
This design was developed by request of a correspondent having made a sort of LED candle and needing to switch off the LED with a puff. This simple, easy to build gadget can be useful as a prop for Halloween...
old dick smith catalog mains led circuit
Hello everyone. This is my first post in quite some time. I obviously do not have an old enough catalog for reference. In the data section, there were references to...
The input data indicates a lack of sufficient information regarding the...
Economy Timer 555 IC
This circuit detects when a window is open (it can also be used with a door), indicates that the window is open by means of a red LED or a blinking LED, and emits a loud acoustic signal from an...
Solar Charged LED Utility Light
Tired of always spending money on flashlight batteries only to have them fail just when you need them? Try this simple circuit out. It would make an excellent science fair project. The white LEDs are quite bright, they provide enough...
ac What is the output voltage of this 555 timer high voltage circuit
The output of the transformer has been calculated to be 125 times higher than the input, based on the ratio of 1000 to 8. Given an input of 12V, the expected output should be 1500V, although there is some uncertainty...
Inductive switching power supply circuit diagram
The circuit consists of a 555 timer configured as an astable multivibrator along with resistors R1 and R2 and capacitor C1. It generates an oscillation frequency of approximately 10 kHz with a duty cycle close to 50%. Transistors VT2 and...
ANALOG FREQUENCY METER
This 1 kHz linear-scale analog frequency meter circuit utilizes the 555 timer as a pulse counter. The frequency is displayed on meter M1, a 1 mA meter, which can be calibrated to indicate readings from 0 to 1 kHz.
The circuit...
230V Blinking LED
A pulsating light is used for signaling purposes with a voltage of 230V. A simple circuit has been designed, consisting of an LED diode, two capacitors, two resistors, a diac, and a diode. The operation of the circuit is straightforward....
High-intensity LED Warning Flasher
This circuit is designed as a warning flasher to alert road users to dangerous situations in the dark. It can also serve as a bicycle light, subject to traffic regulations and legislation. White LEDs are recommended when the circuit is...
