    Modern Day Use for Old Electronics vs New Electronics. Is it Realistic & Practical?

    You are saying Arduinos and Rasberry Pi programming etc., is where it's at for practical electronics nowadays? That is more like software or the IT world. I might as well get certified in Windows and Microsoft Office.

    Modern Day Use for Old Electronics vs New Electronics. Is it Realistic & Practical?

    I took a course in linear ICs and digital circuits in 1979. Tubes in 1970. I worked in a company in the mid 80s where they used PC boards about 20 X 20 inches square with many chips and auto-soldered on wave solderers. Eventually in the 90s they started replacing them with smaller boards and...

    Home Based Income as an Electronics Hobbyist

    "Picking just electronics, although encompassing a few potential sub-sets - is still a narrowing of your choices and potentials" That's true from a stictly economic-survival POV. I suppose you can be flexible and collect cans and bottles or mow lawns too. As far as electronics goes, trying to...

    Knowledge Threshold from Hobbyist to Professional

    In contrast with a student who goes to a trade school or junior college to formally study electronics for a 2 year degree. A vague threshold but is there a dividing line (i.e. "electronics theory knowledge") between someone who gaining self taught skills tinkers around building miscellaneous...

    Just don't let them become Makers and then tell you they are electronics experts.

    Home Based Income as an Electronics Hobbyist

    Maybe so, but a "Maker" only assembles modules, like Arduinos to program with software, and is not an "electronics" oriented person.

    Home Based Income as an Electronics Hobbyist

    Then what would you call the type of project where a person assembles various components like resistors, capacitors, ICs, inductors and other discreet components. Uses his or her understanding of electrical laws and relationships via the laws of physics and electromagnetism and electronic...

    Analogue Meters for Nostalgia Sake

    The red circuit breaker button was so the instructor could tell if someone messed up their lab experiment. or test circuit on exams. It made a loud click when it popped out. VTVM "Vacuum Tube Voltmeter" Haven't heard that one for a while. Once "state of the art". Heathkit made one of those. I...

    Analogue Meters for Nostalgia Sake

    BE & E "Basic Electricity and Electronics" school. Used for all sections of the Navy or it used to be don't know about modern day. Probably Seabees go through that school too if they need to understand anything of an electrical nature. But again don't know about modern day. Al Capone used...

    Analogue Meters for Nostalgia Sake

    I think it was the Simpson 260 that I used in BE & E school at Great Lakes Naval training center. It had a red circuit breaker button that popped out if overloaded.

    Analogue Meters for Nostalgia Sake

    That's like the Simpson I mentioned in my post. Don't know if it is the same model but it looks similar. They were used in electricity school but had a red button fuse.

    Analogue Meters for Nostalgia Sake

    I use digital meters like most people today, but started learning electronics with analogue meters (with needles) example being the "Simpson" model and recently seen some on Amazon for not too much. Does anyone know if these are worth getting for any serious measurement? I don't really need...

    Opinions on This Oscilloscope

    Here is a "Hantek" brand (Major brand) around the same price range as the one depicted in the first post here. Does anyone know if this one is is any better than the scope in the first post? https://www.amazon.com/gp/product/B08YNY9G75?ref=em_1p_0_ti&ref_=pe_2313400_671468390

    Opinions on This Oscilloscope

    Anyone know about this scope? Seems to be the lowest priced common digital scope around with regular tactile panel controls as compared to other scopes of its style like Siglent, Hantek, Rigol etc. $184 U.S. dollars...

    HAM Radio Relevance Currently and Personal Reflections.

    "No, it never was - you didn't have to become a ham. Prior to radio communication people wrote letters. Then they had typewriters and the printing press" I was referring to "Instant", in the moment, voice to voice communication, not written correspondence.

    They were the only way to travel around the world back then which made them unique. That's my point.

    But back then, ships on the ocean were the only way you could travel around the world. That made them unique in that way.

    HAM Radio Relevance Currently and Personal Reflections.

    IN THE PAST it used to be the "Only Way". That was my point. ..."Only Way". so if you wanted to communicate with someone in other parts of the world, you had to become a Ham. That is not true any more. That characteristic of being the only way was what made it unique within that context. Now...
