    12 V DC to a 220V AC Inverter AMplfier Design

    ok i get it , it heats more at the oscillator stage , but it can be a way to tackle it good ....

    12 V DC to a 220V AC Inverter AMplfier Design

    I think you don't get the point i am saying if use a ordinary sine wave oscillator and then attach it to a Step up trasformer , that is it

    12 V DC to a 220V AC Inverter AMplfier Design

    i have another idea  why use a power amplifier  ;D Generate a Sine wave oscillator and then use a transformer simply to step up the Signal of 10V to 220V , i mean as simple as it gets . Beacuse since the 10V is an AC SIgnal. But as simple as it is , the Current Rating of the oscillator should...

    12 V DC to a 220V AC Inverter AMplfier Design

    THere is an idea in my mind which i want to ask if it is applicable or not. THe Idea is to create a SInewave Oscillator , amplify the sine wave signal and that it reaches a 220V P-P , Sine wave oscillator -->  Class A Amplfier --> 220V Sine wave AC Signal The only thing i don't know is...

    wireless transmit & receive data

    I am also interested in this project , balong please hurry and send the PCB layout and schematics man.. i was actually trying to do it with a more easier approach , using FM band and then using carrier audio signals of range 1Khz to 10Khz at the transmitting end and filters at the recieving end...

    Led display Digital Voltmeter question

    HEllo everyone , i would jus like to confirm that if the Eagle Version of the voltmeter    is correct to build , because i need acurracy. i am trying to build a digital voltmeter so i can attach it to a LM2907 Frequency  to Voltmeter Converter , and measure frequencies on the range of 1hZ till...

    Transformer Power Rating

    Hello Everyone , i have a query . The BDW84D BDW83D darlington pairs were really hard to find but luckily i found them. i am wondering if we can use substitute parts for the BDW84D and BDW83D , which are available like BDW84A and BDW83A is really easy to find and even BDW84D is easy to find . So...

    Transformer Power Rating

    Audioguru i have compared the 1W resistor diameter with the modern one also , the diameter is actually the same ... but the difference is its length... and ofcourse we are only interested in the diameter...

    Transformer Power Rating

    The resistor is surely 1W but it is just a little longer thats all , does the length of it effects anything , because you just need the dia of a 1W resistor of any value.

    Transformer Power Rating

    I Know About the 1ohm resistor , i have not fully assembled the project , i am just asking if the inductor is wound right.

    Transformer Power Rating

    Here are the pictures (only of inductor ) . you might see that the project is not fully assembled.  but just see the inductor wound around 10 turns of 24SWG(0.55mm) copper wire.

    Transformer Power Rating

    Hello , Everyone i build this project but because of the two wrong darlingtons , i bought BDW84A and BDW83A and a little inconsistance i am building it again. i want to just confirm that i have wound the inductor 10 turns on 1W resistor of 1.5Kohm i found from my electronics junk and the wire is...

    100W Audio Amplfier By Smart Kit

    The thing is why is it drawing so much current , Q7 is working fine , Q6 is working fine , everthing seems to be fine , what is the problem .... Can you brief me about the theory behind the operation of this amplifier . plzz ...thnx ... :'( :'(

    100W Audio Amplfier By Smart Kit

    Hello .. I am really worried , i am going to buy tommorow , the orignal transistors . but please reply soon audioguru that is the high current of R2 And R16 because of the Transistors . and if i replace them will it work . Plzzzz .. help .. and lastly will it give any signal if R2 And R16 are...
