Simple Pulse Position Modulation Circuit using IC 555
This Simple Pulse Position Modulation Circuit using IC 555 uses one special chip with number 555, as it works like messenger for our electronic things. Also, it send information by making small burst like electric pulse, not like Morse code with dot and dash but this one uses timing change of pulse to talk. Pulse […]
Simple 3V to 9V DC Boost Converter Circuit
This Simple 3V to 9V DC Boost Converter Circuit is like a hero for battery. If battery is only 3V like from old remote then this circuit makes it strong by giving it 9V as many device need 9V to work good. So if we only have small battery with low power but still want […]
Simple Cell Phone Charger Circuit using 1.5V Battery
This Simple Cell Phone Charger Circuit using 1.5V Battery is one special charger we can take anywhere but there is no need to plug; we can charge phone anytime. It also uses a standard AA or AAA battery like the one used in TV remotes, inside, it includes a circuit that boosts the weak battery […]
Simple LED Driver Circuit using IC 7555
Simple LED Driver Circuit using IC 7555 uses one special chip called as 7555 IC, people mostly use it for timing but here we have used for different way. Also, it work like boss and control how electricity connects to LEDs, here, the chip make special pulse signal like square wave and this signal connects […]
Simple LM317 Audio Amplifier Circuit
This Simple LM317 Audio Amplifier Circuit is a kind of like small trick to make speaker sound louder; also this LM317 chip usually is used to control voltage but here it works like small music booster amp. Therefore, it is not very strong amp but still helps give little more sound from the music source; […]
