Solar Cell Based Camera Flash Trigger Circuit
Photography flash units need correct timing; however, many old flash units do not have trigger input, so a Solar Cell Based Camera Flash Trigger Circuit is useful, as this circuit is very simple as it uses very few components and also it does not need any battery. The circuit operates by detecting light, when the […]
Simple 12V Power Supply Circuit with Filter Capacitor
Many electronic circuits require a DC power supply, while the mains provides AC power, also this Simple 12 V Power Supply Circuit with Filter Capacitor converts AC into 12V DC and delivers up to 2 A of output current. This circuit uses only a few components, making it simple, low cost, and easy to build, […]
IC 7805 12V To 5V 2A Boost Converter Circuit
Sometimes 7805 regulator is not enough, as it gives only around 1 amp current; however, many projects need more current for example motors, relays, LED strips and logic boards together. Therefore, we need a simple solution, so we used an external power transistor TIP42 with 7805 IC, as this transistor boosts output current with this […]
220V AC Live Detection and Interface Circuit
Handling 220V AC directly is very dangerous, but still we need to know mains is ON or OFF; so, this 220V AC Live Detection and Interface Circuit is useful as it solves this safety problem easily. This circuit safely senses the mains voltage and sends a clean logic-level signal, then an optocoupler provides isolation, keeping […]
