TV Remote Signal Jammer Circuit

Last updated on 7 June 2026 by Admin-Lavi Leave a Comment

The 555 IC is used in this TV Remote Signal Jammer Circuit because it generates fake IR signals similar to a remote, as a result, the TV becomes confused. Furthermore, TV can not get the real remote signal, so we can watch the show without anyone changing the channel. Also, parts used to complete this […]

Simple Flasher Circuit using LED and LDR

Last updated on 6 June 2026 by Admin-Lavi Leave a Comment

This simple flasher circuit uses an LED and an LDR to create the flashing effect; as the light level changes, the LDR changes its resistance, which controls the LEDs blinking. Hence, there is no need for big chips or transistors but still the LED blink happens, also it uses simple parts like resistor, capacitor and […]

Simple Light Dependent Screamer Circuit

Last updated on 5 June 2026 by Admin-Lavi Leave a Comment

Fun small and Simple Light Dependent Screamer Circuit make sound change with light; it uses LDR like a special resistor which changes with light. Furthermore, as the light intensity increases, the sound becomes louder or higher in pitch, therefore, we call this circuit a Light-Dependent Screamer. Circuit Working: Parts List: Components Values Quantity Resistor 1k […]
