So the law(s) may be forcing them into such actions.Example:https://www.forbes.com/sites/oliverherzfeld/2013/02/28/failure-to-enforce-trademarks-if-you-snooze-do-you-lose/Quote

In reality, it wouldn't surprise me if they wouldn't have done/allowed it, anyway.A bit like when someone makes a nice music video, of their own design (the way the video is done) and music playing/singing, but the song/tune is from a famous band. The video then gets taken down because of copyright infringements.Which can make one sorry for the upcoming artists big effort, at making that video, only to see it taken down, later.tl;drDavid vs Goliath

It's a real problem with with older cars as trim pieces shrink and get brittle. I had a TDS3000 scope that was in great shape but became super brittle and started crumbling. Nothing I could do about it but eventually found a broken scope with a good housing.

He's a bright light in the legal world in a subject like this.Australia has a traditional history of having a local right to repair."He is undertaking research on intellectual property and 3D printing; the regulation of robotics and artificial intelligence; and intellectual property and public health (particularly looking at the coronavirus COVID-19).

Nichrome wire is a quite good and proven technology. Usually, the fan (technically, the fan bearing) in my space heaters dies long before the heating wires start to have problems.Although i must say, for my low power heater experiments i prefer to work with insulated 33 Ohm/m carbon fiber heating wires. You know, the ones used for underfloor heating. Mostly, because those are way more compatible with 3D printed parts than red-hot Nichrome. But i got some old space heaters in my attic, waiting for a disassembly just for the Nichrome wires ;-)

content: Heaters have always been a market full of BS. I.e. "Eden pure" heaters if you want a good laugh. Iirc they use quartz infrared tubes to heat up a blackened copper heatsink that's blown by a fan, and sell it for $lots.For just heating a room, I like the oil filled electric heaters,as there is less very hot surface, and I can park a floor fan behind it to circulate the air properly, vs the dinky fan in a 1500W underdesk type heaters.And that's gilding the lily with a $70 heater and $30 fan that I generally use year round in the bedroom.

content: I came across this video while browsing my collection of woodworking sites.Pretty painful watching someone putting so much concentration into generating such awful joints. All that bared wire and hardly a mechanical connection. The "heat the joint, not the solder" advice is sound enough but itreallyhelps to have the tip wetted enough to transfer the heat! ... and never be afraid of going back to reheat a badly wetted joint.

content: Bright nickel plated terminals don't take solder well unless you scuff the surface with a fine abrasive and use plenty of flux. IMHO the demonstrator should have mentioned that if they are not gold flashed or tin plated, you'll probably need to pre-tin the terminals, then demonstrated that.However its almost certainly not the demonstrator's fault - any chief engineer of a radio station is almost certainly competent with an iron in their hand - its the fault of the magazine commissioning too short a video and scripting too much in it. 4:06 or 246 seconds isn't a lot of time when you take off 20 seconds for opening and closing titles and another 15 seconds for a Menards 'Tool-Shop' brand product placement.

Strange, alternating EEVblog appearance on mobile device - Page 1

timestamp: January 17, 2021, 06:40:51 pm
content: The EEVblog forums have two distinct layouts on my portable devices. One is essentially the normal PC browser appearance. The other is obviously a mobile device layout that makes it much easier to use. For some reason my mobile devices seem to toggle between these two layouts. I can't find anything different in the URL's and don't understand why it will suddenly decide to change - sometimes in the middle of a single session!Web hosting software can detect if the viewing device is mobile, and I suspect EEVblog is trying to do that but isn't 100% accurate. I'm not changing anything on my end; as I said it will suddenly change formats just from selecting a given thread in a forum, and then it stays in that layout for days until it suddenly snaps back.Advice would be appreciated. My goal would be to keep the "mobile" layout active on my mobile devices without affecting my PC-based layout.Thanks!

That includes DVD drives. To know for sure, ask the manufacturer (who will very likely not answer), or buy the drive and tear it down.

Shorting out some SPDIF outputs on a 4 pole jack to a mono jack - Page 1

content: I have an Audigy 2 sound card. For like 10 years I have been using a mono to digital coax to my stereo. Recently I found out that it there is supposed to be a 4 pole jack with 2 other SPDIF lines that apparently I am shorting out. I think what my main question is there any danger in shorting out these other 2 SPDIF output lines directly to ground? Are soundcards generally made to be resilient of this? There are 2 examples of connecting a digital coax here from the manual. One of them seems to use the same mono plug I am using. Also this wiring diagram is of unknown accuracy. The ground in other 4 poles often is the 2nd from the wire side. Also, I have enough miscellaneous hardware that I can put in a 3.5 mono jack and connect it to a riser on the card if I wanted to. I am afraid of blowing something as I am sure there is no problem in the first place. I hear SPDIF is usually 0.5 V.

How to find HP hardware maintenance documents? - Page 1

I also tried search engines with different keywords, all failed.I lost the first URL, but I’m sure those are public documents. Can anyone help me to locate them?Thanks.

They are most likely treated as either no-serviceable, or FRU (module) replacement only. It might be different for server type products, but even then, they would work on a module or board replacement basis. If the documents don't appear on the website on the specific product page, then they are most likely internal use only.

They seem particularly happy about a reduced use of adhesives. I found the use of rotary joints an interesting alternative to cable bends. Is it actually more repairable? If those contacts fail I think you will be up shit creek vs resoldering a wire. So the fix will be to ditch the electromechanical system and route wires for a direct connection when it breaks.I remember I had a old sony wireless pair that suffered from a broken weird hinge, and it made throw it out because you just could not glue that part together or fix it in a reasonable way, even if it had wires (like a laptop hinge). Not to mention regular maintenance will be to grease a weird contactKind of expected it to have a little grease port and sell with a iGreaser ??So you replace a nice reliable wire with a swiss watch and call it repairable???I am kinda depressed because headphones and earbuds were one of the things you can actually fix in a college dorm room with just a cigarette lighter by burning magnet wire and twisting it together. Enough to get by for a while. I bet you could solder by holding a penny in a nail clipper also.Hold out for the vibes honey, let me get my 5 axis printer out from under my bed.

It depends on the dish. What is it?”- “Oh, you know, just general food.”USB-C itself can mean a bunch of things: it can be USB 3, or just USB 2, for various power levels, various lengths, and then the environment it’s gonna be used in. And I’m sure there are more factors that affect the need for a ferrite.

Usually they are added to lower emissions when it comes to product compliance testing.If you have issues with interferences coupled to to cable, a simple ferrite most probably won't help. You'd need a better cable and better shielding.

I have not tried mixing AA and AAAs and the same time. I am not sure they fit physically. This charger will error if it thinks the battery has an issue. I was wondering if in general battery chargers are designed to accept any number of batteries at the same time? In this schematic I can only find 2 places that look they are the application voltages in the upper right I think it is 5.4 and 2.1 volts.

Apparently, the charge occurs separately, and the current sensor is used as a common indicator.Charging AA+AAA, I think, is quite possible. The principle of charging 1 battery or 2, connected in parallel - only a matter of choosing the current or time at constant current.

So perhaps basically 2 wires go to all the batteries in parallel? 2 channels would just double the current? Oh maybe it is a ground completed circuit under Q203 (negative battery terminal)? You probably wouldn't depict that with a ground symbol.

The LCD screen in my scope has failed and a replacement, used would be £40 and up. The scope was bought spares or repair from ebay and I am sure the scope itself works but I cannot justify spending that kind of money on another screen. I know there are boards that can be bought to do the job I want to do, but I know nothing about LCD screens and there are so many different types of connectors that I have no idea how to proceed. I know the higher range owon scopes have VGA out built on to the device so my guess is there is another driver board inside. Any help at all would be most greatfuly received.Cheers.Carlo.

But by messing with the contrast wheel and pressing and twisting on the housing, I found the picture would come on. (The contrast wheel only had a tiny spot where it worked, even when it was new, so don't touch it after that!) Then the scope worked when you pressed on the bevel at that certain spot, lol. So I found if I jammed a toothpick between the housing and the screen right there, tada! Working scope.Edit: I still keep it around, in case I need a battery powered scope. I just checked it. Still working with the toothpick hack.I can't see the toothpick; it's completely hidden, pushed down below the bezel. But IIRC, it is along the bottom of the screen, about one third towards the right, near where the contrast wheel is. If your screen lights up, it might be worth a shot playing with the wheel while pressing the housing on that spot.
