Thank you very much for starting this series Jerry. I actually learned about the logic comparitor you've created prior to you posting this video. Still, understanding your thought process regarding which tool to use in which situation will be very valuable.
Jerry, I'm looking forward to this series as it proceeds. I've been "interested" in electronics for decades, but never took more than the mandatory 2-3 three EE classes required for non-EEs when I got my BSME degree. I've learned some electronics & troubleshooting/repairs over the years pretty much in order to get my PDP-8s to work, or did when my health was better. Now that I'm retired, I want to get back to them and they'll need repairs, including all of their peripherals. (The same for my PDP-11s too!) I lucked into finding the problem on my PDP-8/A's Programmer's Console by using a logic pulser & a logic probe in each hand, along with the schematics, and since I had accidentally found a point where by touching a certain pin on a particular IC, I was able to walk back to a failed chip. Now I have an "antique" 'scope that I need to better learn how to use safely (for it, the equipment being tested, & me). And, of course, several DMMs, and a couple analog VOMs. If you're willing, I'd also like to see similar videos on your fault finding & test gear for tube/valve gear too as you work on that type of equipment!
I'll be watching very closely with this series. I'm sure it will sound trivial, but I have a Commodore 64, and I can't get it to do much of anything. And for the most part the videos I see are people swapping chips, but I'd really like to know the qualifiers to have reason of swapping the chip, not just doing it and hoping.
Hi Jerry. Although I am interested in the premise for this series I'm not entirely sure who it will be aimed at. The title indicates that it will be targeted at "beginners" I doubt that such people will be able to justify or afford to purchase the test equipment that you apparently intend to use. The Agilent 1680AD you demonstrate still costs about £2k on a certain auction site. Your comparator is not exactly cheap and a Fluke 9010 is virtually unobtainium! Surely a "for beginners" series would be better to start with a multimeter and possibly a logic probe before moving on to a basic oscilloscope and possibly a cheap(ish!) USB based logic analyser.
Perhaps you should watch the video again. I specifically say that I will be including a multimeter and if that is all you have it is fine. Also you do not need to use the exact type of analyser I am using. As I have said many times in previous videos you should use whatever you have. A cheap LA can be purchased new for less than £15. As I clearly said I will be demonstrating different types of equipment and this information is SPECIFICALLY aimed at beginners so that it may give them ideas on what equipment they may want to look for based on their interests. I am in no way suggesting (or saying) that you should run out and duplicate everything I am showing.
@@JerryWalker001 Indeed you did mention a multimeter (although not a logic probe) but you also mentioned a lot of expensive equipment too and started the series using a £2k logic analyser. All I was saying was that perhaps it would have been better to start with the multimeter and work up. I understand what you said about using the 1680 due to the bigger screen and mouse control but maybe that could have been a topic for the LA parts of the series - how to use an older/cheaper LA and work round their limitations. Yes, you can get some cheap LA's but are they worth it? Another possible topic for the series - selecting the best/most cost-effective equipment for beginners? Will you be showing LA's that work with Sigrok/pulseview? I have a couple of these and often find them useful. Obviously they tend to load the signals being measured more that "professional" LA's, but it isn't usually a problem and could be another learning point. Just trying to offer helpful views from "outside" - not trying to criticise.
@@spacedock873 NO I did NOT start the series with the LA. I clearly stated that this was an introduction to the series and I would be going over how to use different methods for fault finding. At NO TIME did I state that you needed to use the same pieces of equipment I am showing and that is one of the reasons I usually do not show the fault finding process. In fact on many occasions I have made it clear that everyone should use what they have. I have been asked to show how 'I' go about fault finding and I even showed the comment that was posted asking for this. I am therefore showing how 'I' go about fault finding. THAT is what these videos are about and have NOTHING to do with how to use specific pieces of equipment or what specific equipment to use. I am showing 'Methods' and NOT 'recommended' test equipment. Anyone interested can hopefully apply this to whatever equipment they have. If you are not interested in these videos then just don't watch them.
I wish I'd bought a second hand agilent LA after seeing yours. The tek one I have is technically good but the UI is garbage. It's basically unusable from the front panel.
I’m loving you already less than 30 seconds in
