Sometimes I can not buy electronic devices. Because, far from an electronics store. No products you want, or expensive. I always use the online order. I envy my friends who live in America. That they can order electronics from amazon.com. There are a lot of items. Very cheap, fast delivery and free. But now, I […]

- This is a simplest slave flash trigger circuit. – It will help the slave flash immediately works almost simultaneously with the main flash. – This circuit better than others circuits because without the external power supply. – Since (look at circuit below) use the solar cell get light from the main flash. – The […]
This be Super Bridge 120W Power Amplifier by IC TDA2030 for you like the circuit amplifies that use the integrated circuit. and Transistor BD249 or TIP31 or TIP41 or C1061 and BD250 or TIP32 or TIP42 or A671. It is nice circuit and easy to use. Schematic diagram of Power Amp Super Bridge 120W by […]
This circuit is 100 watt power inverter using power transistor 2N3055. It is designed for you that need to use appliances at outdoor or no electrical places. Someone use it in car or the high mountain etc. The maximum output power of this circuit about 100 watts, it is suitable for a normal lighting (all […]
555 audio ohmmeter circuit This is a 555 audio ohmmeter circuit. Some times, we need to measure roughly the resistances only. In this we can know the resistances by the audio so also fast check. This circuit will use the resistors that unknown value to compare with many the reference resistors. In Figure 1 is […]
