    What music do you like?

    As this is an electronics forum, we have to pay homage to Joe Meek, one of the early innovating music engineers and producers over here in the UK just before and during the big Brit pop explosion early 60's . Extremely influential with his recording techniques, not only with his tape techniques...

    What music do you like?

    I really like this rocked up version of a classic by Leonard Cohen. (Well all of his are classics!) First We take Manhatton.

    Transistor AND gate question

    This is a classic AND gate circuit found in text books. What is not shown is how the "0" and "1" inputs are produced. If you assume that "0" is simply to not apply a +6V to either of the inputs, then the circuit is not likely to work. The inputs have to be taken down to 0V for "0" and up to 6V...

    Electronic Knowledge required for laptop repairing

    I don't think you will need a great depth of electronics knowledge. The important things are how to dismantle the cases and remove components without doing any (further) damage. Also the computer fault codes will tell you a great deal about what to look at, so you would need to learn how you...

    Archiving electronics literature such as Worldradiohistory.com?

    Yes. Some time ago. Just sent another one. Hope he is ok. I have been unable to find another email address.

    Archiving electronics literature such as Worldradiohistory.com?

    Thanks for the replies, but do you know how to contact the site? I have not had a reply from the contact email given on the site. I desperately want to do something with my Practical wirelesses (a few going back 60 years), Babani books and other articles for which he has holes in his...

    Archiving electronics literature such as Worldradiohistory.com?

    Hi everybody. If you haven't come across it, the worldradiohistory.com site ( https://worldradiohistory.com/index.htm ) is a very large collection of old electronics magazines, books and other literature. Does anybody know if it is still receiving donations? It is certainly functioning as an...

    And now something weird

    Now, that is a good point to discuss. What do we think happened to the TV and how did it manage to interfere with the broadband?

    3 Phase Motor - 3 Individual Circuit Breakers - Detect if 1 Breaker Tripped And Shut Down Motor

    For goodness sake -- keep it simple. Anything mains, go for the tried and tested commercial solution. A 3 phase mechanically linked circuit breaker. If the box is too small fit a bigger one. If the cost is too great (in your opinion), consider the cost of being responsible for someone's...

    Examples of Boolean minimization

    Just to be quite clear, -- of course Boolian algebra will still be used. I was not thinking clearly. I meant Karnaugh maps which I have used in anger at the most only a couple of times. Just seemed like another of those academic exercises that you have to know for your terminal exam.

    Examples of Boolean minimization

    For work purposes or just an academic exercise? I really meant Boolian minimisation though. I remember using it once back in the 70's but logic circuitry was usually simple enough to be able to see the minimal use of gates without much problem. I have to admit, I haven't been designing with...

    Oscilloscope uses your PC...Any reviews?

    I bought an old Textronic scope 465B with a bandwidth of 100Mhz for about £120 a few years ago. Does everything I want for less than the cost of a phone or decent audio amp. Would this be a good solution? Spend your time making the harmonic measurements you want rather than trying to get your PC...

    What music do you like?

    I came across this duo just surfing utube for music. They are an extremely talented pair of young musicians who use utube to play their music. Following the links from this utube I found a whole lot of excellent acoustic pop rock folk renderings by a bunch of young musicians Reina del Cid and...

    Examples of Boolean minimization

    Does anybody use Boolian Algebra nowadays?

    And now something weird

    I remember wearing stacks in the 70's. They look really silly nowadays! Fashion is a strange thing.

    Frankenstein's Components.

    To show my electrician apprentices the danger of fire from, say, car batteries, I would sharpen a half length H pencil at both ends and connect it with crock clips across a 12V car battery or similar, capable of supplying a couple of amps. The pencil would be about 6 to 12 Ω and about 1 or 2...

    Larry Tesler , the inventor of copy-and-paste , dies at age 74

    Copy and Pasting has to be one of the most useful tools on the PC! My grateful thanks to Larry Tesler.

    COVID-19

    Just to add, my wife has as usual put me to shame. I am taking it easy making a nostalgic radio from my youth and prattling on about things here and in other forums. I have been sorting out my electronic components looking for the old bits and pieces for the radio and been a bit shocked to find...

    COVID-19

    Hi everybody. Hope we are all keeping well now. Here in the UK, one of my son's had a bad session of C-19 and got through it. He has the antibodies and is in the ideal place to donate them for research, working as he does in a blood lab. The worry now is a level of permanent lung damage, but he...
