content: How long was it operating while wet? Did it fail immediately? What exactly got wet inside?Unless electrolytic corrosion took place over a period of time, usually drying out the system is enough to restore operation.My ice maker upstairs leaked and dripped into my 10 year old P3 system which was my internet router causing it to fail. After drying it out with an air compressor, I had it running within an hour.

content: If it is an older type of display, with a LCD screen and backlight, that backlight was traditionally supplied by CCFL lamps.CCFLs require a very high anode voltage, 600 to 700 volts if I recall correctly. Any water droplets would certainly kill the high voltage inverter.

The local box is in my office room who is well temperate. The Remote Box was under the attic and now in an room on the attic who is a little bit headed.The problem with that box is the connection get loose after I replugged in the power socket. That mean: the run for ~30Min -> 1sec connection lost -> 10min later -> lost again for 1sec,... so on until the lost the connection totally.I have no clue what that could be! I run 3x Delink Media Converter who are next to the Box. Broken Cable? So there is no reason why it "fade out".Ideas?

content: Prior to GPS the standard method for position fixing, when away from the mostly land based electronic aids like LORAN, was the sextant with reduction tables etc. A skilled navigator with a top notch sextant could get down to about 0.1nmile accuracy though were more typically closer to 1nm. A more average navigator would typically be more like 2-3nmiles and it wasn't uncommon to be closer to 10nmiles or worse.The jump in accuracy and precision from sextant to GPS was huge and has had an enormous impact on the economy. The cost to develop, deploy and maintain the GPS system is large, but the positive economic impact is much larger.Brian

content: This video is what how computers would affect us in the future.Quite a few gems in there, like the elitist who said there is no hope in the world anyone past the age of 35 is going to learn how to use a computer, let alone get a job as a programmer or analyst. And clerks are "unskilled labourers who can only read and write and that's about it", and they only have another 5 years before they are thrown on the scrap heap. That academic could not get any more condescending. But his warning was dead right about centralised records on people, including health records. Other weird predictions: Prior to 1980, only 10% of the present workforce will be needed to provide goods and services for the community.Having worked with IBM as an engineer for 18 years, I cringed at the IBM meeting part. Today, the company is a basket case.Bottom line: No-one knows the future, so never say never.Enjoy...

Others said that the missing episodes are located elsewhere on the internet but I haven’t really looked.Anyway, the episodes that are left on Youtube are extremely informative and enjoyable to watch particularly in regards to the engineering side of it, high drama in the extreme although they do milk this aspect quite a bit and I somehow suspect the narrator to be a red cordial addict, he’s definitely on something, that’s for sure. In this episode the needle masters attempt to push a needle through a five millimeter thick plate of aluminium, can it be done and can they do it ?.Supreme Skills Playlisthttps://www.youtube.com/playlist?list=PLC2a6fM0Q8RlFYDDy7v4huWdJ1yC1elkrAn Additional List Herehttps://mega.nz/#F!jqZyEapS!RXDMf_s2Z-Nujn8hXci8dQ

If it is anything like the previous OpenDays (the 60th anniversary of CERN during the Long Shutdown 1 in 2013, where I was guiding a couple of groups), I can definitely recommend the RF tour at Point 4. This is where the particles are actually accelerated, using superconducting RF cavities powered by large klystrons. Unlike the detectors, which are usually overcrowded, there are less crowds so more of a chance to actually see stuff. If it will be anything like last time, visitors might get a chance to walk along the accelerator in the tunnel for a few hundred meters.

content: i clicked half way into the video and there is some bomb to defuse so I can hazard a guess that maybe its something like wire mod for garys mod but instead wire mod for fort nite where you can use basic logic elements, electrical amplifiers, counters, etc in game to make contraptions that need to be defused or have unique behavior thats quick to implement rather then trying to hard modify game code.It's pretty cool in g-mod you can make a analog sentry gun/missile seeker out of something akin to a virtual prototyping board and mess with it a little in ways using the game engine to simulate RL physics to kinda get an idea about interference and how weird behaviors like decoys and shit makes ideal logic and analog circuits behave in a way you could not with an advanced simulator even without going through serious effort. Also the effects of dampening and time constants in real life applications. Probably ww2 era behavior but still it got me into electronics IMO.the majority of it is more like programming a microcontroller but there is some kinda weird stuff you can do thats quirky and can be educational to someone that is already knowledgeable and quite fun.

Crimping tool for JST-PAD connectors? - Page 1

content: I'm trying to track down a basic crimping tool for the JST PAD series connectors (like PADP-16V-1-S). The suggested tool from JST is the YRS-245 runs about $1500. Is there a basic universal crimper that would work reasonably well? Like the PA-09. This isn't something to be used for production, but when working with the PAD connectors, I would like the ability to recrimp a wire if I manage to damage something.Housing Examplehttps://www.digikey.com/product-detail/en/jst-sales-america-inc/PADP-16V-1-S/455-2143-ND/1300224JST YRS-245 Crimping Toolhttps://www.digikey.com/product-detail/en/jst-sales-america-inc/YRS-245/455-2048-ND/1164621PA-09 Universal Crimping Toolhttps://www.digikey.com/products/en/tools/crimpers-applicators-presses/228?k=PA-09

content: Did you look at the tooling guide?http://www.jst-mfg.com/product/pdf/eng/eTOOL-5A.pdfThere are a couple of WC-series tools listed for the SPH terminals, but not for all of them. The WC hand tools are still not cheap ($300-500), and you'd have to verify that you can use suitable terminals for your application, but they're very good for low volume work with loose terminals. We have WC tools for XH and ZH terminals, and you pretty much couldn't ask for a better crimper for even the tiny ZH terminals.The PA crimpers can be okay, it really depends on the terminal. For a 2.0mm series terminal they're probably fine if you only need to do a few, but they're still kind of a pain because you have to do at least two separate crimps, and often the terminal will bend in the process.

content: I bought a VFD clock kit to build up as my first step into the Nixie tube world because I think Nixie tubes are the coolest things since sliced bread! I understand they are different but they are well cool too and if I build this one and it works ok I will get a Nixie clock kit next to build.My problem is as I was building it up I was double checking the components with a meter before installing them on the PCB and noticed the seller had sent me around a dozen 104nf caps instead of a dozen 104pf caps as is printed on the PCB.All the parts are clearly marked out on the PCB and the component value is also marked on the board too so they are real easy for beginners like me to follow. I wouldn't have noticed the mistake otherwise.It could also be a misprint on the board and not the caps but I think not.I have mailed the seller but they are in China so who knows when they will get back to me.Just as a bit of info for myself since the problem has arisen and i'd like to know these things, can anyone here tell me if the difference will matter a great deal or if it should be ok to just install the 104nf instead of the 104pf and the clock will be fine?

content: I'm surprised you can find 104pF capacitors; it isn't exactly a standard value. And, of course, specifying them is dimwitted in the extremeApart from that, there will be a factor of 1000 difference. Whether that is significant depends on what function they are performing in the circuit. Since nobody other than yourself has any information about that, the validity of any answer is, um, questionable. not strictly true; it is an E192 value, i.e. 0.5% tolerance or lower.http://www.logwell.com/tech/components/resistor_values.htmlOne might question whether substituting a component specified to 0.5% with one that is 100000% higher might cause problems.
