Hi friends, my son started on a project like electronics. But we will teach children how good I can find a good Electronic project lab and appropriate It worth the money to pay I found Maxitronix 300-in-1 Electronic Lab Project kit from Elenco Electronics, and it fit my son learned a lot along with the [...]
This is a simple electronic alarm circuit that imitates the chirping of a canary. The circuit is nothing but a Hartley oscillator with few more passive components added. As the capacitor C1 charges through the resistor R1 and the transistor Q1 is driven to cut off. This makes the oscillations to stop. As the capacitor [...]
The bridge rectifier circuit uses diode 4 the the converter AC to DC, but this circuit uses zener diode as a rectifier instead of diode plain will be current in the direction of the direct bias in the cycle the first current flows through D1 to. to load and then returning the ZD2 cycle, while [...]
