    want mobile jammer circiut

    In the UK we can just use a normal analog TV aerials, but some places need a high gain aerial. I wasn't realy intending to make a Freeview jammer, i wanted to make a signal amplifer to save money on buying a high gain aerial, just that i don't know wat frequancys Freeview uses.

    I found out what a ESP file is. For those who don't know what it is, its a picture file that needs to be opened with Abode Illistrator or Coral Draw.

    how to design very small 6V power supply @100mA

    Whats a switching power supply?? ???

    Help, data sheet!!!

    You could get a ohmmeter and test the leads to see the resistance of them. High= No coil between those 2 tested leads Low (or near low)= Theres a coil between those 2 tested leads

    Just an update on the design, the dual pot isn't ment to be there - i was getting mixed up with the LM386 that has a veriable gain  :-[

    Bridge problem!

    From the datasheet it looks like the TDA2005M and TDA2005S are both the same. They are dual amps - 10W each There are plenty of application configurations for mono and stereo. Hope it helps  ;D TDA2005.pdf

    What are FETs, Diacs and Triacs???

    Hi, i've seen MOSFETs, JFETs, FETs, Diacs and Triacs being used and things but what do Diacs and Triacs do? And whats the difference between MOSFETs, JFETs and FETs from normal transistors??? And how are thay used??? Please explain.... :-\

    PCB Design

    Can someone design a PCB for this schematic?? (The dotted cap. is ment to be a 10uF elec. with a dual pot. in series (one for each amp) for the gain and the 2.5M is the volume) The amp type i'll be using is the LM380N. Thanks LM380_2.5W_Amp..pdf
