Quite likely, the SSD killer is electrical. We can't entirely rule out mechanical vibration, but SSDs are pretty robust mechanically. A simple rubber mounting would increase the resiliency even further. Also make certain that both power and data cables have enough slack. Vibration might cause them to come loose, when under tension. So, to address the ...

First off, electrical and magnetic problems are not as bad as problems of vibrations and air contamination. Moisture in air plus dust or chemicals can corrode or short paths quite easily, and in our installations they are the primary reasons of failures if the devices aren't protected properly. The best option is just keeping all that's not necessary on the ...

The three terms specify the function of the component, not its size. A shim is a component used to fill up an unwanted gap. Shims may be flat or tapered, and are often specified as "select to fit" parts, rather than as a part with a predefined thickness. A spacer or standoff is a fixed size component designed to separate two other parts by a known amount. ...

You did not specify what materials you are working with and neither the dimensions. I made some assumptions. First of all, the coolant circuit is likely driven by a pump. Therefore you need to know the flow rate $\dot{Q}$ the pressure needed on the pressure side. You can get more information here. For your specific setup to cool the PSU you have pressure ...

The pressure requirement could also be to raise the temperature at which the water boils. The boiling point of water depends on the pressure it's at; higher pressure raises the boiling point, as the following image shows. As you can see, water at atmospheric pressure boils at 100 C, but water at 3 bars boils at about 130 C. When water starts to boil, it ...

Well, I would think that two smaller ones rigged up in an "amateurish" fashion (apologies, but that's we both are, right) are going to be worse than just one (sufficiently large) properly mounted heatsink. That giant triangular piece closest to the CPU would probably delay heat transfer -- even if you have excellent cooling on the other side of it. What I ...

Each color red, green, blue that makes a pixel has a range of 0 to 255. So each of the colors has 256 possible settings. 256*256*256=16.77 million possible colors.

Estimated lifespan is given by the manufacturer usually as "MTBF = 2000hrs" but in "normal conditions" - what you describe is not normal. Why are the SSD drives failing - physical damage or poor connections. One anti shock mounting used in the past was a mercury bath but you probably won't be allowed that !! But you could make an oil bath version...

Really a comment but too long: I've dealt with PCs on the factory floor (woodworking), they proved quite resilient. Our initial setup which was basically trouble free: We mounted the PCs inside a cabinet, the front was clear plastic slats (think what you sometimes see on a walk-in refrigerator freezer). The original intent was to maintain a slight ...

The chances of all hard drives using the same grade of magnet is very low. Different designs call for different grades of magnets. It is possible that some hard drives use N52 magnets but in general there is no way to tell. If it is really important for you to know the grade, you can send magnets out to be tested. They would could use something like a DC ...

Another option would be to use a vacuum cleaner, that way any dirt is not pushed inside the computer but its pulled outside.

Your are correct that the smallest surface area will be a limit on the thermal conductivity. Before we dive into that lets look at the over all approach and some other limits. Are your temperatures typical for your laptop on forums or per manufacture? Heatsinks are just lumps of metal so you can easily inspect the quality, but heat pipes are full of a ...

Most computers / computing devices will have a real time clock (RTC) built in. This is normally included in the processor or motherboard chip set rather than as a separate part. It will be designed such that when the system is on it uses the main system power to run but when the system is off it has a separate power pin that is connected to a small battery. ...

In addition to the other answers: in the environment you mention, it's possible there is metallic dust in the air. When that gets into the computer, you can get electrical shorts. A sealed case (or ventilation with high-quality air filtering) can help if that's the case.

As others said, SSDs are resistant against vibrations - there are no moving parts, unlike magnetic hard disk drives. Both of these technologies are, however, vulnerable to electromagnetic fields, as others stated as well. Providing protection against that may help. You should, however, also not discount other factors. (A quick note: this list definitely ...

We are assuming that the problem is caused by shock or vibration. There can be several other causes, such as temperature, humidity, corrosion, chemicals, as pointed out by others. One more approach would be to get the drives to a non-hostile place and extend the connection with cables. This may need your computers to run from external drives. If you ...

One requirement is serviceability and time between refills (of either ink or paper. When printing 15 copies of a 100 page report you don't want to have to stand next to it and refill the paper and ink 10 times before it's done. Instead you want to push the button and then pick up the stack for binding later after you had your coffee. Having components be ...

These environment requires a printer which are supposed to include photocopying, fax, scan and a risograph among other functions. Risograph are highly needed in offices and schools for high-speed duplication of printed materials such as questionnaires, examination papers, forms, etc. The risograph can replicate a copy into 500 pages in about 2 minutes so ...

The keyboard contains many switches (100 in my keyboard at this moment) and the simplest solution for a keyboard assembly that contains no decoding circuitry would be for each switch to have its own line going to the motherboard, plus one common ground. This is inefficient. The simplest scheme to minimize the burden of all those wires in the interconnect ...

I order to solve this problem there one needs to understand the following ADC range which is the maximum and minimum ADC input. For this problem the range is 3.2V, -3.2V. ADC resolution which is the smallest distinguishable change in input. For a 12 bit converter this would be 6.4V/4096 = 0.0015625V Below is an example for range of 3.3V based on a 12 bit ...

There's two different "shut off" methods: showing a black screen and actually powering off. To show a black screen, the backlight stays on but none of the pixels are energized. Light that gets polarized from the first filter doesn't change orientation (because the liquid crystals aren't energized) and so that light gets blocked by the second filter. ...

The output of the preamp is analog. The computer accepts digital. You will need to use an analog to digital converter before trying to send the data via blue tooth. Without knowing anything about it besides what it says on the web site, NewEgg has an ADC that might be what you need. The output of the ADC is not something you can plug into your computer so ...

3) What is the name of this sort of connector? (a general commercial name which will let me locate this on eBay if I happen to break it) I'll hazard a guess that this is Molex PicoBlade. If that's the case, then the pitch should be 1.25mm. Please measure the pitch (center-to-center distance between the pins) and update your question with that ...

It looks like a Molex or AMP 4-pin power connector. Note the AMP and Molex versions are similar, but not interchangeable. See https://en.wikipedia.org/wiki/Molex_connector. AMP connectors have one or two tabs which click into place and "lock" the parts together when you connect them. You need to bend the tab(s) to release them while you are pulling on the ...

Punched cards, like punched paper tape, magnetic tape & magnetic drums were all forms of data storage in the early development of digital computers. They served a similar function as magnetic hard drives, solid state drives, memory cards & USB memory storage devices currently do. They store data and software (programs, applications) that can be ...

The ports referred to in a "port scan" are logical. Consider the fact that all network communication to a computer typically is over a single physical connection, usually Ethernet. There are multiple simultaneous conversations happening routinely. Think about how the network traffic for fetching email in one window, a web browser in another window, ...

The link you posted is not an ODB-II simulator, it is an ODB-II interface you can plug into your car. If you have read the Hook-up Guide on the website, you'll have noticed that the interface port is a DB9 connector, usually used with serial connections, this one uses the UART protocol it seems. Furthermore, I haven't read anything about VGA in your link. ...

Friction is the cause of "hysteresis-like" difference over the whole stroke. Friction always acts in direction opposite than movement, so on the way "down" you act against spring strength + friction, while on the way "up" you act against spring strength - friction. force hysteresis coming from the switch construction. The schematics don't show the switch ...

The term "out-of-order" here refers to "out of order execution". e.g. if your program has instruction A, then instruction B, then instruction C, it some situations it may turn out that if you execute them in the order A, C, B (instead of A, B, C), you get the exact same result but the program executes quicker. An example of when this would happen is if ...

In principle this should work fine. According to https://reference.epson-biz.com/modules/ref_escpos/index.php?content_id=82 the commands to drive the printer are just combinations of ASCII control characters like ESC, FS, GS, etc, which can be transmitted to the printer exactly the same way as "ordinary" printable letters and numbers. A complete table of ...
