Let’s use two simple Analog VU meter schematics. If we take the amplifier connected to the speakers. It is very dangerous.If your amplifier has a higher power than the limits of the speaker. It may make a very bad sound. More important is the speaker and amplifier may be damaged.These circuits may help you! Simple … Read more
The simple 6V Power supply circuit. We have a lot of circuits for you. Some ideas may be good for you. All circuits use normal component, easy making. Read more
See two negative Voltage Regulator circuit ideas. Do you know? we can use PNP transistor and Zener diodes in these example circuit 12V,9V at 700mA output Read more
This is a 12v to 300v dc-dc converter circuit using 2N3055 transistors and 2N1305 are pillar equipment and power transformer transform the sky tallly go up then change voltage regulator rectifier with diode and Capacitors make output have voltage about 300V at Current 55mA. With this circuit a friend can apply the work next. Request … Read more
I am going to show you how to use a phototransistor circuit is simple. To make it a light controller switch or relay with basic components like a transistor, IC, and more. Imagine when The Sunlight then the Relay Switch on to load as a fan runs. we are happy. Then sundown. the relay switch … Read more
