It's even more amazing they did all that without computers, a sound grasp of the fields it involved or even basic telemetry data of their flights. Not only had they learn things the hard way, it also meant what could be learned from failure was limited. Truly an incredible endeavour, no matter how unpleasant its purpose.
countries other than china that offer OUTGOING ePacket shipping? - Page 1

content: Why doesn't this exist? In theory destination rates are standardized by the UPU, so once you get your package onto a flight the costs should be the same regardless of where you are shipping from. We already have canada post facilities (and lots of close-by post offices) at major airports, so why can't they offer such a direct-to-ePacket service at those post offices?

Maybe because their exports at the retail level would not justify it.

But tempting.The intended use is an hour of quiet time after work in my cabin.I am currently work on a cutter dredger and break from the low to medium low frequency noise would be nice.This noise is generated by the drag head, water and sand in the pipes and hydraulic winches.I avoid expensive stuff, as a bag can fall in the water during crew transfer and be massaged between two hulls before getting gaffed out of the drink...And I could give one a trip to one of my philipino team members without breaking the bank... but I would not do that if it was really crap.So tempted, but if they are no better than bog standard 25€ Bluetooth headphones, I’ll pass.

content: Thought I would share this method for holding things while working on them.The arms are called friction arms that are generally seen used for holding dial indicators or cameras.I decided to put clamps on both ends to create a flexible holding arm support. The attached picture showsa control panel from a surface grinder being held up by two arms while I work on it. I have also used this type of support tohold circuit boards and hold cables and connectors in alignment for soldering.

You can find single clamps for sale as well.Make sure you get an arm that has 1/4-20 threads on both ends.A few more examples of use can be found in a post I made athttp://www.zenith.aero/profiles/blogs/starting-wing-skins-and-a-few-ideaNoga does make better arms, but are also more expensive. I use Noga for holding dial indications.However the cheap arms work well enough for general work holding.The only mod I made was that I had a problem with clamps not staying threaded on tight to the arm. Iused a little bit of loctite on the thread to keep the clamp on.

author: CatalinaWOW
author_rank: Super Contributor
timestamp: January 23, 2019, 06:52:34 pm
content: I believe many control systems of this type control the body by applying a torque to the momentum vector instead of the spin axis to allow a more rapid response. There is then another loop that over much longer time periods controls the spin rate. Much thought goes into making sure everything stays within limits and when and how to dump or add momentum to the wheel.The saving grace is that for many systems the average over time of the control required is zero, so ignoring friction there is no cumulative need to add or subtract momentum. The problem is that this condition can be violated by initial inbalance, and external forces can cause a non-zero average over periods that can last hours or even days.

I think he almost had it, probably just the thing of tweaking things.Wonder if it would be better to spin the wheels at 50% speed initially, that way you just slow down or speed up, but always keep same direction.

author: Brumby
author_rank: Unknown
timestamp: January 26, 2019, 03:32:11 am
content: The "50% position" for reaction wheels is stationary. They then accelerate in one direction or the other, depending on need. If the flying platform had a naturally stable hovering position, then the reaction wheels would not be rotating at all.The setup used obviously had some inherent stability issues which were too extreme for the control system to deal with. Perhaps tweaking might home in on some better results, but from what I saw, it was a long way from critical damping.

Though, this design is new and it's only beginning to gain adoption.

content: Halcyon asked me a while ago to build the Twitter relay bot for the EEVBlog IRC channel (irc.austnet.org #eevblog, kiwi client setup at eevblog.com/chat).Well that was a while ago, and all of a sudden I made it. Currently all it does is a few very basic bot things, primarily it will automatically check @eevblog (Dave's Twitter) and relay any new tweets directly into the channel. There are also a few small easter eggs, and random payloads triggered by a set of words. The bot is the EEVBlog user on the IRC, and all public commands can be viewed by saying EEVBlog Help.Now here comes the slight difficulty. Now that I have a bot running on a machine, doing things, what else should I make it do?We have an IRCStats bot in the channel, which I have been thinking of replacing with something a bit more integrated that updates more frequently, or even on the fly. I've thought about automatically linking any YouTube videos uploaded, but that's all piped in through Twitter anyways. Other ideas that were thrown around were things like stock monitoring for the shop. My ideas right off the bat is just plugging it into as many EEVBlog things as possible. The idea behind an IRC client in a Discord room was tossed around, actually by the people over at AustNet, but I don't have the immediate skills to do that, and it doesn't sound like it would be enjoyable to make, just for 2 people to use it on an EEVBlog Discord that doesn't even exist.So, what should I stuff into it?

content: Hi All,I have an industrial thermal camera that uses a somewhat unusual power connector. It is not the more common LEMO, Fischer or HRS connectors but I have seen it before on a Cleartone CH800 handheld transceiver. The camera model is a Electrophysics 7290A but sadly the manual does not detail the connector model or maker. The plug and socket have no identifying markings or numbers on them, even under the rubber casing sleeve.I had a look through the usual Hirose catalogues and Farnell, but so far failed to identify it. Does anyone here recognise it and know who makes the connector. It may well be an obsolete item as it likely dates back to the 1980's. Even a comment on other equipment that uses the same make of connector is welcomed as I may be able to find a reference to the connector maker somewhere.Thanks in advance.Fraser

content: Hi,I made a repository on github a while ago. It is useful for users of both KiCad and PartKeepr.https://github.com/HendriXML/KiCad-BOM-reporter/wikiWhen prototyping this a very handy tool to know were components are located. It can even help to choose between available parts.

content: Today I posted some cool updates:First the possibility of merging calculated specifications with schematic ones.Showed in this thread:https://www.eevblog.com/forum/projects/lasertrigger-circuit-signals-invalid-exposure/Second the possibility to define numerical specifications as a range.So now it is possible to match with resistor values from 10k to 12k, with capacitors larger than 1000uF. etc.In this way more or less of matched components will popup in the report. This helps making decisions about which component to actually use - and where to find them.

content: Hello AllI have my own YouTube channel, I use it mainly to just record what I am doing on the bench I have no plans to monetise the channel now or anytime in the future.I shot and edited some footage of a friends Car project and let my friend have the raw video footage to make his own video as he also has a small channel. I have edited my own version of the footage and want to upload it to my channel. I also want to give him my edited video as featured on my channel for him to upload on his channel. He would just remove my channel introduction and insert his own, with no other alterations. So potentially there will be two identical videos with different creators loaded to YouTube.So my question is, is this allowed and will it invoke any type of automated strike from the God of YouTube. Me and my friend don’t care about sharing or copyright etc of our work as it is just for fun and not for profit etc.Thanks Regards Chris

As far as I'm aware you can license your footage to anyone and everyone, which includes a single friend. I'm not sure how Youtube deals with it, though. As long as you're not part of programs which automatically scan content, you should probably be fine.
