    Backyard DIY Auto Repair and Backyard DIY Electronics Repair

    Martaine2005 answered it satisfactorily for me. As far as what you just said, you are offering help with the technical function of the trees. I am questioning the forest.

    Backyard DIY Auto Repair and Backyard DIY Electronics Repair

    OK, so there you go.....All 3 recognized at the same scholastic level (Certificate) but it takes more brain power to work at electronics repair and maintenance.

    Backyard DIY Auto Repair and Backyard DIY Electronics Repair

    Let me put it this way: A person wants to get a Technical Certificate in a 2 year Junior college. He or she can pick one of these 3 core curriculums which scholastically are suppose to be at the same level which are really Associate Degree level but without the History, English, Art etc general...

    Backyard DIY Auto Repair and Backyard DIY Electronics Repair

    I personally have some training in Electronics, but not enough to call myslef a technician. I had no training in auto mechanics or appliance repair either but managed to figure things out and do successful repairs and maintenance. My main question was "Is Electronics understanding and...

    Backyard DIY Auto Repair and Backyard DIY Electronics Repair

    Do electronics experts here think it possible to draw a parallel comparison between these 2 functions for practical useage? I have changed my brake pads, replaced a broken steering rod and CV boots (and grease), changed spark plugs, changed engine oil, added AC coolent, and other maintenance...

    Older Big Discreet Circuits versus Multiple Micro Circuits in ICs

    Superb answer....Thanks What you described is exactly within the context and comparison I was trying to get at. The volatile nature (ESD) of ICs is significant as you described, but my question was more theoretical-philosophical rather than practical. I especially like what you said that...

    Is It Worth Repairing My Fridge or Should I Replace It?

    The freezer feeds cold air to the bottom section. There is a vent in the freezer connecting it to the section below. Make sure it's not blocked My fridge was doing the same thing. I checked out youtube and found that there is a drain tube in the freezer, which drains water down to a pan on the...

    Older Big Discreet Circuits versus Multiple Micro Circuits in ICs

    This subject-question is rather old school antiquated, but just for understanding the significance modern micro-miniature circuits in IC packages comparedto old school big circuits. If you took an old discreet circuit like an audio amplifier, or radio or whatever complete circuit with all its...

    As my handle shows I am retired now (in my 70s). When I was a teenager I was interested in electronics and built a few Heathkits including an analog SW receiver. I aspired to get into Ham radio and hung around with a few Hams in my area (USA). the Vietnam war needed drafties and I ended up in...

    I don't have a 3D printer. Is there a market for what you describe? I happen to be familiar with model trains. There are a lot of companies already making small electronics devices for that hobby including flashing LED accessories. I don't think that hobby is widespread and popular at this time...

    So what do you think is still available? What niche of ET do you work in? I'm not looking to work in a full time job anyway. I had a part time business in mind, sort of like the old TV repairman that doesn't exist anymore, but my skill level is not even that high. I suppose "hobby"...

    Yes that is what I wonder about concerning fixing broken electronics as you say for consumers. I'm only considering part time if I could qualify Servicing industrial equipment sounds too much like a full time job that would make you liable for any equipment used by a company. The key to learning...

    Note, John, that you were asking very similar questions in January. What changed? I'm slow & cautious although, believe it or not I have pretty high IQ. and my situation is in flux. Also some health issues surfaced. I was pursuing another retirement possibility that seemed viable but it has...

    Thanks for the advice. Those look like old Radio Shack kits. I have built kits down through my life, Heathkit shortwave receivers, VTVM, a radio in a college class, but those just taught me assembly and soldering, not the combination of theory & circuits needed. As I said, I'm not totally...

    What I am looking for is some kind of hands on course that takes you step by step from the most elelmentary circuit like battery, resistor, light with fairly detailed relationships of Ohms law, then multiple resistors, mabe multiple lights etc. (for lack of a better description). Then add a...

    Thanks for the course and book recomendations everyone. Is there a course that uses hands on, step by step construction from the most basic circuit to more complex circuits to demonstrate generic general use boilerplate circuits used in most devices, starting with analog? I imagine it would be...

    You said: "A very good knowledge of basic and applied electronics" What would that include? Also, as being a HAM, would you recomend the ARRL handbook as a clear and systemized learning manual, which goes step by step from square one and on up the ladder of more and more involved circuits...

    R.I.P. Vic Flick (from the James Bond tune)

    There is an episode of "Pawn Stars" TV show where he comes in and sells his Fender Stratocaster which he said he used to create that Bond theme. I think they gave him around $50,000 for it.

    Thanks You learned all that on your own? Also you said: "except any form of processor or other complex IC" Could you elaborate on that a little?
