    GOULD OSCILLOSCOPE OS4020

    Did you Google the mfgr and model number to see what's out there?

    That, or global warming got to it.

    Eachine H8 mini quad copter with keychain camera

    Wonder how many people watched your video, looking for 'Where's Waldo'. I thought my post would be funny, you outdid me.

    All in a day's.... work?

    If the wife asks you why you keep going back out to the shed, tell her you're working on a defibulator in case she ever needs to use one on you. (The tingle from the cap when flipping the board over). Scratch that, if it's unappreciated humor. Glad you're feeling well enough to get back out into...

    Was that a neighbor lady in the bikini next door? Pretty cool, for cheap.

    Value preceding summation?

    ... was that in English? (sorry, this simple tech couldn't resist)

    Idea how to bring back concord :)

    I'm thinking KJ6EAD has a point. $3,000 a seat was a bit pricey. Who knows, maybe the French have converted their Concords into spy planes, and never told you. Maybe they're still out there, ... like Elvis.

    Plasma Tv Flex cable repair.

    What I'm seeing in your photo is damage to the circuit 'trace'. Kits are commercailly available for circuit trace repair. I suggest buying one of the commercially available nickel or silver flake particle liquids, I think they're called 'nickle-kote' or 'silver-kote', The ones I used to use were...

    Intermittent serial connection

    I'm not a computer person, maybe someone here can point you in the right direction. Your post made me remember an issue that sounds like yours, that happened to me many years ago. At that time, if I remember correctly, the computer guy who worked the problem said he had to do something with the...

    Undervolt the input of a transformer - what happens?

    Everything, depends on the load.

    potential health hazard from electronics

    Most companies in the U.S. have pretty strict compliance procedures pertaining to safety/health hazards of this. Probably why most manufacturers moved out of the U.S. to less restrictive countries. Apparently it's OK to let some others face the risks, while the rest of the world reaps the...

    Continuity testing wire capacitance

    hevans1944 suggestion is the way to go. I got my TDR from a guy that used to sell cable out of the back of his van. He'd roll-up, I'd tell him what lengths of wire I needed, an he'd use the TDR to give me the exact length. I bought it from him when he retired. Don't use it much since...

    Undervolt the input of a transformer - what happens?

    Sounds good. Unfortunately there are a lot of different types of motors, and some applications call for sealed motors to prevent the introduction of contaminants, and/or are restricted in physical size for the application. All we know from fatman57 so far, is that he's using an 'electric...

    Help with wiring

    Odds are, something is wired incorrectly for one device or the other. My initial thought is whether or not you wired your new jack correctly. Is it a mono or stereo jack, and do you realize they're designed to disconnect one speaker circuit, when you insert the plug into the jack, and re-route...

    Undervolt the input of a transformer - what happens?

    I don't remember the theory, but in practical application a lot would depend on your load. Like cjdelphi I'm not sure what your circuit looks like. It seems to me that if you undervoltage what a transformer is designed for (not a problem by itself), but your load draws more current than what the...

    I require help repairing a Kitchenaid Water Kettle

    Did you check the wall socket, to see if you blew a fuse/circuit breaker in your home?

    I can't find a replacement potentiometer

    Well, you're talking about replacing the pot, so I assume you have soldering skills. I'd pull the existing pot, and check it for manufacturer information stamped on it. If it has data, you can look for an exact replacement. You're looking for a replacement that's the same physical size if you...

    Can I use a blender motor as a fan?

    It's an off-topic comment, but I'd be careful about how the fan-blade assembly is attached to this new motor shaft. The odds are they'll be different inside and outside diameters, with set-screws to hold the fan blade assembly to the shaft. At high speed, you don't want the blade assembly coming...

    Skoda car radio - No output sound.

    We don't know where to start yet. Your small coil is probably intended to cut-down on RF interference on the antenna input line. It's highly unlikely that that is the problem (unless you can see physical damage of some type). Just reading across the coil for a (very) small resistance will tell...

    Skoda car radio - No output sound.

    My initial thought is that you said you thought you had a problem with the reception signal. That may not have been a reception problem, it may have been an amplifier output semiconductor going bad. If you want something to check, (with the power disconnected), measure the resistance across the...
