Long Range FM Transmitter Circuit (2km)
This Long Range FM Transmitter Circuit (2km) send voice or music on FM radio, as it can cover up to 2 km range with good antenna. Also, it uses small microphone to take sound and then circuit make signal; then signal goes to antenna and any FM radio can catch it. Finally, it runs on […]
30V 1Amp Transformerless Power Supply Circuit
This 30V 1Amp Transformerless Power Supply Circuit works like small adapter for our electronic, as it takes normal high voltage electric and change it to low safe voltage to what our devices need. No large transformer is required because the circuit uses special components such as capacitors and diodes to perform the same function. Like […]
Simple Flip Flop Circuit
Think about small switches, they only do “ON” or “OFF”, but this Simple Flip Flop Circuit is same like that but for electronics. It stay in two state like 0 or 1, this small switch is very important it can remember stuff, keep data and help control what happen next like timing and by coordinating […]
