Circuit of using buzzer instead of figure light

Published:2011/4/13 22:02:00 Author:Nicole | Keyword: buzzer, figure light

If using a motor to watch indicator light, it will not decern easily weather the light is on or off in daytime, but the buzzer circuit can compensate for it. To turn on the ignition switch, the JFET 2N5434 also will be turned on after about 7s delayed time, so in the process of starting car and increasing oil pressure normally, the buzzer will not to ring; then using indicator light to watch oil pressure sensor and motor temperature sensor. This circuit can be fixed in those not being used buzzer plastic casing of bridge house.   (View)

6n3 Tube amplifier power supply circuit diagram

Published:2011/4/2 4:24:00 Author:Nicole | Keyword: Tube amplifier power supply

As shown , after the power through switch and inductor, then through T1 transformer, through rectifier filter then supply power to he filament and TDA2822, T2 is connected to the T1 secondary, producing high voltage, the rectifier filter and regulator supply high voltage to 6N3. The signal outputed after amplified by 6N3, then through TDA2822 drive headphone. In this paper, the circuit is simple, without any debugging, the component parameters have been indicated in the schematic, the select of components can refer to other articles, to use some components with better performance. This machine is particularly quiet in the static, sound is very good.   (View)
