To begin with, we use piezoelectric transducers in a footstep power circuit because they convert foot pressure into small electrical power. Furthermore, piezoelectric effect means crystal which makes electricity when press or stress happen and if we press special crystal a small current comes out. Hence, Simple Footstep Electricity Generator Circuit uses parts like piezo […]
Simple Crowbar Circuit
Simple Crowbar Circuit is safety part in electronics, as it protect from high voltage spike or surge; it work like fuse but does not burns and it gets short circuit fast to stop damage. Furthermore, it use SCR or TRIAC for shorting, transistor or Zener to trigger; also trigger watch voltage all time and if […]
24V Flasher Circuit
24V Flasher Circuit can ON-OFF 24V thing like lightbulb again and again and we can use to turn signal or warning flash light also. Furthermore, this circuit uses IC 555 which is common for making timer or flasher and we can also change flash speed by adding resistor and capacitor to IC 555. Hence, this […]
Simple Solenoid Driver Circuit
A Simple Solenoid Driver Circuit is a setup to control solenoid using low voltage signal; solenoids are like magnets and they change electric power into movement. Furthermore, they need more voltage than small digital parts like microcontrollers can give, also the driver works like a switch and it lets small signal turn big current ON […]
IC LM386 Based Voiceover Project Circuit
IC LM386 Based Voiceover Project Circuit is small audio project, which takes mic sound and makes it louder with LM386 chip and then sends to speaker. We can also use this for public speaking, mix audio with mic first or talk in presentations, as IC LM386 chip is easy to use and uses less power […]
Simple White Noise Generator Circuit
The Simple White Noise Generator Circuit is a DIY project that produces sound like radio hiss or static; so we use this circuit for sound effects, privacy noise, and testing audio equipment.” Noise come from electronic parts, so we can use resistor or reverse transistor for noise, also capacitor remove too high or too low […]
