Who makes rod mounted project boxes? - Page 1

content: This enclosure fits between two rods on an industrial robot. I want to make some replacement parts and I'd like to match up the original enclosures if at all possible. Unfortunately I'm having trouble finding any project boxes with this sort of rounded slots on the sides. Maybe it's a custom part? Alternatively I'm thinking something like get a Hammond case and 3D print an adapter bracket.Background: I'm trying to make new radios for a bomb disposal robot I got a while back on eBay. The originals are damaged and I'd like to put some more modern long range ones (LTE?) on anyway.Any help is appreciated. Thanks!

content: That looks like the usual aluminum extrusion with endplates style of robust box. Unfortunately custom aluminum extrusions arerelatively affordable, even for limited volume production, and thus fairly common, so you'll have the devil's own time trying to find the original part if it was bought in as a box, or if it was custom for the OEM, an off-the-shelf equivalent.If it isn't too long, it could be duplicated by machining from aluminum billet stock, but it certainly wont be cheap.I suggest using an off-the-shelf box extrusion with custom oversize endplates, to provide the grooves that engage with the rods.

content: Thanks for the link! Yeah, its likely that would be quite affordable for the robot maker then. Upon closer inspection I've also discovered there is an internal non-extruded lip. So I'm leaning more towards a custom part now...maybe extruded followed by some simple machining.It's not just the end plates as there is a matching channel down the middle that matches the end plates. While I've found some slots on enclosures I haven't found any that have this round style. In any case I agree that using a standard box and putting custom end plates is probably the way to go.Thanks for the suggestions!

content: Wikipedia has 1983 as the date the earliest commercially available solid Aluminum electrolytic capacitors became available:https://en.wikipedia.org/wiki/Polymer_capacitor#HistoryAre you sure the equipment is 1970s?If it is a solid Aluminum electrolytic, and its capacitance is in tolerance, and its its ESR and leakage current still low, I'd simply put it back. Otherwise if you can't find a physically compatible modern equivalent, replacement with a solid Tantalum capacitor with at least 50% higher voltage rating should be acceptable. However we'd need to see that section of the circuit from the schematic (with supply rail voltages marked) to be certain, as Tantalum caps are extremely intolerant of high current transients and reverse voltage and have a nasty tendency to catch fire when subjected to either and connected across low impedance supply rails.

Cyclists would probably endorse it in hot or wet climates.You've also prompted me to make another point. Because of the way the debunking is done for base entertainment and YT views it reinforces the uncritical clamour for more entertainment. It polarizes the forum along the lines of those who find it entirely boring and would prefer more constructive activities and those who love the simple entertainment. I doubt there is a big middle ground. One is nourishment and the other a temporary sugar hit.

It's remarkable that anything so mechanically complex and sensitive could be produced in such high volume at such low cost. Nearly every home in the USA had at least one CRT in it, likely the most complex device any of the family members would ever touch yet cavalierly dismissed as just another appliance.Thanks for posting this.

content: It looks like a common mode choke. Surface mounted common mode chokes are often not in a standard package and do not have a standard footprint. If it is a common mode choke, the opposite terminals should measure less than a few ohms, and the terminals next to each other should be open circuit (measured when removed from the circuit). Common mode chokes rarely fail.If you can get the schematic for the product, it should tell you exactly what the part and its part number is, then Google the part number.

Wireless M-BUS smart smoke detectors - Page 1

content: Hello,I am in general incompetent in the field of radio communications and I have recently just started learning things, using SDR and reading a lot about the field of RF.Some months ago, our building management company installed in every apartment Wireless M-BUS smart smoke detectors, which is required by law in Germany (the smoke detectors, not the wM-BUS). The devices are said to have 10mW transmitter (TDK5110) and work on 868MHz and ping every 30 seconds.Some local dude, measured the RF power at 1 meter distance and it turned out to be 500uW/m^2.He wrote a long article about the health risks. He seems to be a very competent engineer with lots of professional equipment. Of course being competent in a given engineering area does not exclude the probability of also being a nut job and a tin-foild head.To me 500uW seems to be a negligible power, but I don’t have any real world experience in that area. I read that such power density can be easily achieved at your home by the TV stations, which blast at kWs of power at the tower. And probably I lived long enough with my WiFi router ...I looked for information, but you stumble upon sites like ‘Bioinitiave’ and similar, which claim that legitimate medical studies are suggesting serious risks and we are being lied to (possibly by the government or by the lizard people) that RF is safe and even nano-watts will affect you, blah-balh. The general claim is that we really don't know the effect of RF on biological organisms as this is new and hard to research, intentionally underfunded field.I do not believe in 5G (or similar) conspiracies, however looking at the stupid thing in direct line of sight above my bed and knowing it pings every 30 seconds is getting on my nerves. Not to mention the installitation with my consent, required by law. Or the fact that it just does no need to ping that often, because it is not connected to a central hub that will call the fire brigade automatically. No, that's probably the original firmware used in hotels. I think that just the manufacturer decided to save penies on firmware changes. These devices are supposed to be checked once per year with walk-by or drive-by receiver, so why they ping every 30 seconds remains a mystery or incompetent engineering.I like to hear people with real world experience, who actually work or worked in that area, because all this is getting on my nerves. I think I am losing it, not without the help fo the lock-down and having very restricted social life. My brain is in farting mode and I need some reality check.On the other side, hacking wM-BUS protocol is fun as well. If anyone has the EN-13757 documentation, please let me know.

But even sohttps://www.bbc.co.uk/news/technology-55475433References to decades-old computer software are included in the new Brexit agreement, including a description of Netscape Communicator and Mozilla Mail as being "modern" services.Experts believe officials must have copied and pasted chunks of text from old legislation into the document.The references are on page 931 of the trade deal, in a section on encryption technology.It also recommends using systems that are now vulnerable to cyber-attacks.The text cites "modern e-mail software packages including Outlook, Mozilla Mail as well as Netscape Communicator 4.x."The latter two are now defunct - the last major release of Netscape Communicator was in 1997.Original tweet herehttps://twitter.com/billatnapier/status/1342877839008411648

Maybe there's even a serial code on the DMM PCB, with a date code., IDK fluke stuff, I don't own any yet, wait now, YES I DO, of course I do, just not DMM's, I have 3 Fluke Oscope's.If I was selling a DMM, I would check date codes if I had the time, so yeah go ahead and ask, maybe they will.

content: Hi guys,Is there some way of knowing which footprints are interchangable? I always just look for landpatterns in the datasheets to make sure components fit, if I don't immediately find it in my footprint library(s). Then I draw them myself. But often afterwards you realize many of them are interchangable, like for example "PQFN8 5X6", "DFN 5x6" and "PowerPAK SO".Now JEDEC is supposed to be the "standard" for these things right?I looked around a bit but I didn't find a general thing to make clear how component packages switch out. Is there a way to make sense of all this madness?!Are there documents to show you which footprints fit which packages? How packages are named? Why some packages are barely different from others? Why some of them have double names?(SMA, DO214AC) etc.

author: Alti
author_rank: Frequent Contributor
timestamp: December 21, 2020, 09:00:50 am

It would also be handy for selecting replacement components sometimes.
