220V String LED light Circuit using one Capacitor

LEDs differ from filament bulbs and are significantly at risk of existing variations, without a decreasing capacitor the LEDs starts off blowing off with the least voltage variations if associated immediately or by way of resistors. for that reason a advisable capacitive power supply circuit should be applied through this. You may must contain the […]

RF Field Strength Meter

This is an exceptionally simple RF Field Strength Meter circuit. The main stage acts as a crystal recipient. Utilize a germanium locator diode (like 1N34, yet AA119 is substantially more normal in Europe), a silicon one won’t do. The frequency is controlled by L and C. For the FM band and VHF, wind a loop 5mm in […]

Precision Rectifier Circuit

The post explains a simple precision rectifier circuit using just two opamps. This precision rectifier operates from an asymmetrical supply, handles input signals up to 3 Vpp and has a frequency range that extends from DC to about 2 kHz. Its amplification is unity, and depends mainly on the ratio R4/R3. Opamp A1 is connected […]
