You explained the common-mode choke filter backwards. In normal operation the two windings cancel each others flux out thus giving a very low impedance. When in common-mode filtering they work together to create the high impedance to the high frequency noise signals.

Americans might know that printer paper better as "tractor-feed" printer paper. People thought the sprocket wheels looked like tractor wheels for some reason. That style of printer was commonly available well into the 90s, so it isn't just for the old and wisened to remember.

A filter circuit board like this really should be a single layer copper design, so you can see and thus know there is correct gaps

Very old, me. Speaking of fan fold- There was a live stream a few years back where Tom Scott and crew printed the comments from a live stream and fed the result directly into a shredder. I do wonder how many viewers had ever seen a dot matrix printer before.

I liked fan fold paper printers. When I was at uni I could print out assignments in one of two long continuous scrolls. I'd then physically cut and paste edit it on my bedroom floor. Perhaps not to everyone's taste but it just suited the way I liked to work with a full overview. One the subject of work wear I use those military surplus British AFV type flame retardent ones. Essentially armoured vehicle overalls. So many useful pockets and all zipped. I buy then big enough to go over thermals in the winter and to be a bit baggy in the summer. My partner who does all the welding and fabrication swears by them as she creates a lot of sparks and fire 😊

Using MOVs between neutral, ground, and hot is pretty common in the USA inside of cheap power strips that claim to provide protection against power spikes. They are sacrificial, and I don't know how much of a voltage spike they can withstand before letting the magic smoke out.

I think your explanation of the common-mode choke is the wrong way round. It should be that, if the current is flowing in the same direction in both wires, the magnetic fields add to each other, requiring a magnetic field to be built up, which makes the choke act like an inductor. And if the current is flowing in different directions, the magnetic fields cancel out, so the choke doesn't act like an inductor.

Hate to be the counter to the "leaded solder" argument but it's not largely about the effect it can have any *single* person but what happens to that lead content when it's inevitably sent to landfill and environment impact long after we're all dust. On a personal note I have both some decades-old leaded solder and modern lead-free solder and, I would assume due to lengthy oxidation, I've found the lead-free stuff far easier to work with. Even accounting for the age, I've also found solder with a Sn/Ag/Cu/Rosin mix perfect for small amounts of SMD repairs, something I found absolutely not possible (again probably down to skill rather than materials) a few decades ago.

All the control devices at work use the screw connectors. I lost track of how may intermittent faults have be traced back to someone installing the wire under a clamp. I always tell the guys to turn the screw backwards until it clicks which indicates the screw is all the way down. At the lowest point the screw is out of the clamp and it is not possible to put the wire under it.
@bigclivedotcom4 жыл бұрын
I routinely wind the screw out, insert and tighten the wire, then pull the wire to double check.
