content: The auto predict on the iphone 10 is awesome(maybe), or does my phone have nothing to do with it, and its the software update all iphones have, the ios X.XX or what ever its called? Does it live in my phone or on a server?The reason why it matters is its extremely personal the data collected. I pressed the latter Y on my phone today and then used auto correct to spell out a whole sentence, didnt enter in a single letter, and not "sup bro lol" it had the word doctor and hospital in it. Privacy or convenience? Do I even have a choice anymore?

Probably a Markov chain generator or similar, trained on your past messages. I expect Apple stores a copy of that database of messages online, to seed any other phone of theirs you buy.

I just found out about the register and could have saved myself years of grief if I knew how to copy it.I ordered all my data from uber on paper and they sent me dozens of pages of just a spread sheet with my GPS coordinates duration time; to where I was down to the 0.1 second for weeks I accidentally left the app on. I wasn't happy.Anyway to get that info from apple?

Correct Terminology for a Phase Related Concept... - Page 1

timestamp: April 01, 2021, 07:20:43 am
content: So I'm coding up a function that performs anti-aliasing for a periodic pattern in a fragment shader. One of the function arguments is a phase attribute for the periodic signal. Instead of representing phase offset in angles (or time), it is represented as an offset percentage within the total period width (kinda like how duty cycle is typically defined). My question, is there a specific name/terminology/nomenclature used to describe "phase percentage"?

author: jwet
author_rank: Frequent Contributor
timestamp: April 26, 2021, 02:18:26 am
content: I think "phase percentage" is as good a name as any, "phase fraction" might be more precise, "phase/360", "relative phase in %"? I've owned test equipment- a Tek storage scope that displayed phase this way when you were looking at signal without a time scale in X, but I've never heard of a name. I looked at its manual and it just avoids giving it a name. Good luck.

timestamp: April 26, 2021, 05:56:07 am
content: Well what are you explaining is the PHASE. Phase is timing relation between two signals, expressed as a fraction of a full cycle of signal. You can express it as percentage (0-100%), degrees of circle (0-360°) or radians of circle (2Pi). That is only dimension. It will usually be periodic, or can be that it needs several rotations to sync up so you might have 720° of phase delay relative to some signal.Time delay is absolute measure, phase is relative to cycle time.

content: Phase percent or percentage seems right to me since it literally is per 100. Just be glad I did not select the units; I would have used phase per 256 to make the binary math easy. Doing so is a major advantage because it removes all need for modulo operations.

It definitely requires a router, i.e. doesn't talk directly to your phone or laptop without one.I haven't used this one for a while and today it isn't responding to the automatic timer settings. It seems to work manually. I tried reaching ankuoo's web site and they are hard down. Even downforeveryone says they are down. I'm wondering if the web site is at all tied to any server the unit may be trying to reach.Seems like the unit should have its own timer that would be sync'd to the Internet time servers though and not require a mothership to tell it when to time on and off. Anyone know how this unit works?

desoldering trick? - Page 1

author: madires
author_rank: Super Contributor

content: I don't know if this is widely known or not, but when desoldering components many add additional solder to help with the desoldering process, i.e. for a better heat transfer and to break any oxide layers. From my experience it is the flux core in the solder what helps, not so much the solder. So you can simply add flux to the solder joints before desoldering the component and won't wasting solder. A simple flux made from colophony and IPA works fine. Works also great with a desoldering gun/station. For really crusty joints you still might have to add a little bit solder.

content: Lead free solder melts at 217cLead based solder melts at 180..183cLow melt solder melts at even lower temperature.The added solder can mix with the existing lead free solder, lowering the melting temperature so it can help if you use a desoldering wick or solder sucker to take off the solder off a larger surface with less risk of damaging surfaces due to too much heat applied...Yeah, the flux in the solder core or additional flux helps break the oxides, but the added solder also helps by increasing the contact area between your soldering iron tip and the pad/lead you touch with your soldering iron. More heat is transferred from your tip to the area with solder.

Euro power bricks that can auto detect 240 or 120 - Page 1

content: Yesterday I purchased a NETGEAR WNDR4300 v1 for $15 Canadian to use with openwrt. They failed to tell me it had probably a German adapter and it had a us 2 pin outlet to 2 rod little thing on the end. The unit seems to work fine and I am using it to write this. I chose to use a 12V 2A dc adapter I otherwise had because I don't trust this set up, but they likely had used it that way for some time. The euro brick said 220-240 v and did not mention 120V. When I measured it with a DVM I got to my surprise 12.xx volts. This leads me to believe it was in fact auto switching.How does this detection work? And can there be any issues with it? Maybe you are better off if you are the lower power standard?

timestamp: April 18, 2021, 06:15:07 pm
content: Those things will automatically adapt to a wide range of input voltages, particularly at low load, but running them out of specification permanently or at high load is not a good idea. At half the input voltage, current draw increases two times to deliver same output power and you never know if the circuit was designed to cope with it.

author: tom66
author_rank: Super Contributor
timestamp: April 18, 2021, 06:16:15 pm
content: There's no auto switching. Either it's a wide-range flyback (likely at that operating power) which means the transformer is wound to typically operate at normal loads down to about 90V ac, or it's got an active PFC stage that boosts the AC input voltage up to a DC bus voltage of around 380-420V. Active PFC is rare at low power levels, but that then allows the transformer stage to be made with much tighter design margins, which can be beneficial for efficiency, packaging and cost. It's generally a legal requirement (effectively, due to 3rd harmonic regulations) at around 65-75W output power.One thing you might encounter is the primary-side cap is smaller for a 240V only power supply. This means its output voltage might have a nice 120Hz component on it, as the converter struggles to keep up with loads near the bottom end of the AC cycle. For some devices, there will be no obvious effect, as they rarely use the 12V dc output directly - it usually gets post-converted to 5V, 3.3V, 1.8V, etc. So an input of 12V dc with dips down to 8-9V may not cause an obvious effect, but the long-term effect will be that ripple current cooks the capacitors in the adapter and, if present, the ones in the router, as they end up carrying the full load current of the device at 120Hz.

It's a PITA.But look very closely at the housing, there is often a logo molded in the plastic somewhere.Your connector looks like a TE automotive connector.https://www.te.com/usa-en/products/connectors/automotive-connectors.htmlOr maybe not. Connectors are endless.

content: Hi fellows,Noise is unwanted for measurement machines most of the time.And most of the time we are doing filtering process to a acceptible range that generally smooths our graphic. But in medical machines i think that range is very very tiny and cant let noise to achive a test results or a robotic arm's motor that works in someones brain. It's really a serius job, you cant just let noise to act a motor when a robotic arm inside of a human.So how they are filtering the noise? I googled but there is no topic about it, maybe my key point was incorrect. Do you know how they do it or can you give me traces?

I kinda can see why they are doing it. If I were Daniel, I'd want to measure impact of my marketing campaigns. Measuring number of leads is one possible metrics.Having said that, after putting my (fake) personal details I wasn't able to enjoy the comics. My brain was thinking "why do they want my personal details" and "what are they going to do with them", or "how do they protect my data?".

I can build models on Fusion360, mesh them in Gmsh*, and apply my forces in X and Y software when it does not come with built in 3D CAD.I've had to code up custom functions in fortran, and c, etcAlthough, I don't really know what I'm looking at: I've been exposed to the difference formula, Runga-Kutta, LU matrices (linear algebra's my weakest maths), and Euler's method from calc 1.and all I really know is I guess we matrix-ize the equations, then solve them. We accept values within a tolerance (convergence)But I don't really know about "relaxation factor", and the methods used in a solver (e.g. Jacobi, BiCGrip; stuff like ILU tolerance, I don't know what ADS is and AMS is)So instead of googling terms like someone might recommend, is there a nice youtube channel that introduces me these things?IMPORTANTLY added, I intend to learn how, in MY projects, relaxation factor, tolerance(s), (the harder stuff e.g. picking methods), will affect my results accuracy and computation time, etc.My boss told me there are FEA modeling advisors that have careers doing this - That's sweet - I'm trying to connect with the projects more than putting the Legos together and typing up the code.

With my fresh skepticism I looked into a teardown of a "Wanptek" that seemed affordable, nice and reasonably well-made. There were a few details that weren't excellent, but the biggest complaint was about the separation of primary and secondary. Apparently it wasn't big enough, guaranteeing it to fail any CE testing. To me, the device looked otherwise modern and well-madehttps://www.youtube.com/watch?t=301&v=M-3kJ59n67U&feature=youtu.beThen I looked at a Conrad/Basetech lab supply of similar cost, which has much lower specifications. It's safety-approved, but otherwise looks plain miserable to me:I'm looking for some opinions to make head or tail of this. I'm only going to use these devices/adapters myself, not reselling, and weighing the risks.
