AC Power Meter
Posted on Wednesday, December 15, 2010   •   Category: Miscellaneous


If you attempt to save power in the house thoroughly, you can not ignore the standby power consumption of appliances. We made a device to measure the power consumption of appliances. Actually, to say the AC power meters measure the 100V AC current is flowing in the power cord over do it. In general, the voltage is measured casually, is difficult to measure the current. To cut off a part of the circuit current flow from a current meter must be connected to it.


PIC18F2550 Project Board
Posted on Wednesday, December 15, 2010   •   Category: PIC


The new PIC18F2550 Project Board was designed as the development platform for student projects. The board platform is suitable for developing the microcontroller based instrumentation. Students may build the signal conditioning board, plugs it to PIC project board, develops the code and programs it with loader cable easily.

Table Lamp Circuit with LM555
Posted on Wednesday, December 15, 2010   •   Category: Miscellaneous


If you want a Power Lamp Flasher at normal electric power, try out Table Lamp Circuit like this is. It uses the integrated circuit NE555 as the core component. It controls the blink rate of the lamp. Use the power transistor for about 20W or current 1.6A. The Q3 can be replaced by TIP41 or H1061 or MJ3055 or 2N3055.
