This post shows how to build a flashing light using a special xenon tube stroboscope. It uses just a few parts and plugs into a regular outlet 220V mains supply to make the light flash really bright! This circuits is powered with high voltage which can be dangerous. Seek the help of experts electricians. This […]
Simple 35 Watt Bridge Amplifier Circuit using TDA2030 IC
This article explains how to build a 35 watt amplifier circuit that is extra powerful. It uses a special chip called a TDA2030 in a special way to basically double the amps output. This makes the speaker sound much louder. Building circuits with high voltage can be dangerous. Do this under adult supervision and a […]
Simple Cable TV Amplifier Circuit
Cable TV channels use the thin wires to pass through. As these signals go further they start getting weaker. Similar to a little radio where a cable TV amplifier circuit boosts the signals strength. This makes it more possible, that viewers may get a clear signal. Circuit Working: Parts List: Component Quantity Resistors (All resistors are […]
