    Solid state...transistor amp design problems

    Hi there SILVERsound, and welcome to Electronics Lab  :) How did you calculate the resistors? I belive they are totaly wrong, with maybe hte exeption of the colector resistors! ??? What are the amp used for? A guitar preamp? Have you measured the voltages on the transistors, I belive they are...

    IC tester

    Hi there Renero, velcome to Electronics Lab!  :) Can you tell us more what you mean? If you mean a universal IC tester, that can test all types of IC:s I belive it is not possible. :( There are so many types of IC:s, digital and analog amongst others. But if you mean a simple tester for 741:s...

    logic probe

    Hi faraz nazir, welcome to this forum, nice to have you here ;D LT=Lamp Test, RBI=Ripple Blanking Input, RBO=Ripple Blanking Output Have you read the datasheet for 74LS47? A link is here: http://www.ee.washington.edu/stores/DataSheets/74ls/74ls47.pdf If you read the datasheet carefully you can...

    Voltage cutout for analogue meter.

    Hi Then you should get an adequate ammeter, or at least shunt. It is usally the shunt that will broke. //Staigen

    Need help identifying capacitors

    Hi gogo2520 Sorry to inform you that you are wrong at a few of your values ??? 100nF=0.1uF, the voltage is right 330nF=0.33uF //Staigen

    wireless transmit & receive data

    Hi balong, thats good! If everybody did this, this board would be much better! If you look just under the window you type in, you see the text "Additional Options..." , just click on that one and follow the instructions, its obvius what to do! Allowed file types: txt, jpg, gif, pdf, mpg, png...

    amplify the power (infrared)

    Hi ryanleung Maybee you should switch to FM instead, and at the same time have it pulsed at a somewhat higher current. A schematic would be fine. //Staigen

    9v + (2xAAA) = ????

    Hi Audioguru Hehe, a switch always have at least 2 contacts(connections), else it can not perform its task! ;D ;D But i belive you mean poles(contacts) :) :D ;D //Staigen

    9v + (2xAAA) = ????

    Hi helio905 This, i belive, you have to explain a little bit, and a little schematic would be nice too Staigen

    9v + (2xAAA) = ????

    And a relay will complicate things, and a linear regulator will waste power. But, a swiched regulator will be just fine, but will complicate things too. Staigen
