    Frankenstein's Components.

    A comedian once quipped: "I have no idea why they've made a calculator watch, I mean, when was the last time someone asked you for the time, AND the square root of 157?" B^)

    Frankenstein's Components.

    Not "basically free", but I did buy something like this for an old PC PS. https://usa.banggood.com/Geekcreit-XH-M229-Desktop-Computer-Chassis-Power-Supply-Module-ATX-Transfer-Board-Power-Output-Terminal-Module-p-1418198.html?cur_warehouse=CN&rmmds=search It plugs right into the main connector of...

    B&W A7 no power - PSU repair help please

    Can you substitute the power supply with a bench supply to see if the system works that way? Do you know what voltage the PSU is supposed to be putting out? I'm not sure what you meant by "jump this 5v to another pin of the connector on the PSU that it should turn on the amp," I suspect that is...

    Panasonic SAPM-31 Mini hifi, Tapedeck motor running all the time

    Good answer Edd, I recall a Pioneer tape deck (1980s era) that left the capstan(?) motor running all the time, but maybe, as you wrote, it was only when the deck was in a particular mode.

    Help, what SMD is that?

    Ed, you did a good job identifying the part in question, I wasn't sure what it was from the photo(s). But, do recall the OP mentioned they were looking at the PCB "just for fun", and didn't know what the part was, not that they suspected it was a problem with the motherboard. B^) Over the years...

    how to properly connect fingerthump potentiometer

    Hmmm... That potentiometer is monaural, are you wanting to control a stereo headphone? Bertus's drawing shows you the internal workings of your potentiometer. If your headphone is monaural, you could insert the (on/off) switch into one of the two headphone wires and connect the middle connector...

    Generac Niagara 400 (watt) standby generator

    As the project was put on "the back burner" over Winter, I do not recall which procedure (or two) I used to re-flash the field. IIRC, one attempt was with an electric drill. As the weather is warming, I might be getting back into it shortly. But, in the meantime, the vegetable garden will need...

    Generac Niagara 400 (watt) standby generator

    I did not try to read it after uploading it, I had already printed it out and it is quite readable. The schematic on the "dodgy" website is quite readable too.

    Generac Niagara 400 (watt) standby generator

    Well, the 8 HP horizontal shaft engine is still a nice Consolation Prize! I already have two 5 KVA gas generators (non-inverter) for standby power, so this one is not essential.

    Generac Niagara 400 (watt) standby generator

    Last summer I bought a (very) used 400 watt gasoline powered generator for $50. The salesman (an auctioneer) said the former owner took "pretty good care of his stuff". When I got it home and began to check it out, apparently the former owner had not changed the motor oil when needed. (It was...
