    Electronics 101

    I think that's why most people are on here...to help and also learn from others. I get a kick out of helping others and also learning new things, that's why this is the best forum on the net and why unfortunately for some I keep coming back. :) So come on give us some questions you must have...

    Electronics 101

    Hello Foxtrot. It is quite daunting initially stepping that foot into the art of electronics. There are lots of books available, some better than others.....but as I found out years a go, no one was there to help me understand something when I didn't. That was my biggest hurdle. I then started...

    Basic Soldering advice

    I have heard a certain illegal drug works quite well. :)

    A question about cross talk! :)

    That may have been the case 50 years a go before people started stealing specific terminology and using it for something else :). Unfortunately crosstalk is one of many. It is widely accepted and is printed in many EMC / EMI papers that crosstalk is a term used to describe EM interference from...

    A question about cross talk! :)

    Cross talk is a form of EMI. Thanks Adam

    A question about cross talk! :)

    I think OBW explained that well. Cross talk can take two forms one will be dominant than the other, capacitive or inductive, but they are always both there. Which one dominates depends on the geometry of the circuit / wiring and circuit operation. It's quite a complex subject and very difficult...

    Identifying an individual to a system - Ardiuno

    Does it have to work over a distance? Are you allowed to touch it? IF you are what about a Biometric sensor. Cheers Adam

    Modifying AGC circuit

    Maybe you will.. you can get flexiable versions now for automotive use. :)

    LED PSU board, wondering what it is..

    Then the capacitor must be for HF noise suppression. Conducted emissions, immunity or both. Adam

    Basic Soldering advice

    And also leave solder on the iron when you put it in the holder, never put a dry iron in the holder. Wipe it off for the next use. Adam

    Basic Soldering advice

    Lead free solder sucks. Look for a non lead free solder that has flux in it, but not a vegetable flux. You can get a no clean flux version but I have never used that. I can't remember the name of the reel I have at work but will find out its name. Adam

    LED PSU board, wondering what it is..

    Um it could be a transformer less power supply. Adam

    LED timer circuit

    Hello For those sort of timings and if you wanted to do it with out a micro and RTC (real time clock) you could have a look at using counters. Thanks Adam

    Getting antenna to radiate

    Yes I have seen that, nice one. I just thought he might like to know how the values are calculated. So yeah we can use your circuit, it would be beneficial to this thread I think if you run through how they came up with those values? Cheers Adam

    Getting antenna to radiate

    I'll see if I can work through an example for you and simulate it. Showing you how to match the amplifier to the load. It won't be until tomorrow if that's ok. Thanks Adam

    Getting antenna to radiate

    Why did you choose a 1.2K as your collector load? Thanks Adam
