    Yes - that guy is the wrong species of salmon, but the bear will still eat him (if he's a non-smoker).

    My pro photographer friend sold his lenses 12 years ago. Modern phones killed his business.

    I don't even know how to make that kind of blotch? One time though, I took a pic with my phone while it was twisting somehow, and the image of the horizon had a weird wavelike translation on it. I wasn't able to repeat it.

    Weird how they all want us to go to Albania. I fear there might be some kind of trap. Of course I don't fear that others will be trapped , just me. Who can we send to explore this far-fetched possibility?

    Maybe if you try theorising really hard. If your beliefs need changing fast, you might need iconoclastic acceleration. I understand that that sort of thing is quasi-legal in California. Then again, once upon a time, I told a joke about gravity, but it fell flat. PS I could have been more...

    Closed Loop Gain Formula Derivation - Why Superposition Theorem is valid for the inverting amp with finite loop gain op-amp.

    Hi :) Perhaps it's not the best textbook. Of course everybody has already told you to get The Art Of Electronics so do it. :) I hope that your goal is to be able to use op-amps successfully in analog circuit designs. It doesn't really look like the most helpful presentation to me but explaining...

    Can someone suggest me an upgrade for my car that doesn’t require any wire cutting or voids insurance and warranty, but still gives an excellent econo

    Senseless, but it happened.

    Hi Amit :) Alas, a lack, usually of money, frustrates us all, and often prevents us from noodling around in the car of our dreams. You're looking for a creative solution... but that solution might not exist. Essentially in this case, you seek magic, which can nearly be done by following the...

    Transistor Price Question

    Have you seen my copy of the Akhasic telephone directory? I thought I left it here... That might have been about 2015... ? ...

    Transistor Price Question

    Old age... what a nuisance! Nobody gets out of here alive! but Taoists e.g. learn to simply step out of their bodies. Of course that means the end of all their fascinating experiments with the Real...

    And now something weird

    Does this lead to any exploitable non-linearities? With sound, an amplitude modulated high frequency carrier can be amplified to such an extent that the low pressure half of an oscillation tries to go negative. Of course the poor waveform hits a vacuum beyond which progress is imaginary and...

    How to de-solder?

    Yeah we did. There'll come a time the OP will need to revisit their work. When that time comes, and the connection needs to be redone, there are better ways ( in my opinion)... 1) Clean all the old crusty metal slag away with a small file and sandpaper, so that the metal is clean and shiny. 2)...

    Hi :) Nobody's said it, so I'll say that your rewiring of these lamps should be safe... I'm recommending 12V DC, which I expect you'll get from a car battery. With 12V you've got lots of options... the simplest and probably most reliable is the automobile indicator flasher suggested above. Just...

    Price versus quality

    Well, thank you, dana. I've already done the circuit design for my machine, but this alternative might suit me in future. I'd better check it out :) Mark

    Price versus quality

    :) My health tends to break down when I get involved with computers - I have to take a very light approach to my electronics work. So it's true to say that I haven't kept up with technology. However I imagine that I can get quite good results using a few combinatorial chips. This project is...
