content: I am a third year student going into fourth year next year in Electronic Engineering that is minoring in RF. For my minor, I can have up to 3 classes total. I have already done 2 classes that have content relating to antennas/cables and communication systems circuits.My third class can either be an SCADA Systems class that has content such as: PLC programming, smart relays etc, or another class in Integrated Circuit Design that has content such as: VLSI design for board/chip design.Not sure what class I should pick for my third class in my RF minor: SCADA Systems or Integrated Circuit Design? What would be more beneficial to my minor or job aspects?

content: SCADA is not about programming. It is about distributed equipment over a large area (like a plant or even larger), and controlling various equipment from a distance, by various communication protocols and various physical layers.Sure, a professor can make a SCADA class only about PLC programming, though that would be only a narrow aspect of SCADA, and would be rather called a PLC Programming class, not a SCADA class.My point is, SCADA is not software only, it is about keeping an eye over a process that is happening over a large area, usually an industrial process, and often with a cool control-room, like this:Photo from:https://www.nasa.gov/or like this:Photo from:https://www.bcd-urbex.com/chernobyl-nuclear-power-plant-ukraine/

content: What brightness? I thought the rods/cones are basically integrators responding to the intensity-time product. The eye does have a huge dynamic range.Saccades do not affect this, as far as I know. I can see LED car tailights strobing/flickering doing a visual sweep that normally appear to be lit steady.But 5usec seems wrong, simply way too fast for our physiology - unless you are in a dark room with very bright LED but I've never tried that kind of speed.The only time I've been into saccades is making emdr machines.

content: Yes you are correct; the periodic 'pearls' that happen with modulated light and head or eye motion, that's in millisecond range, not much below 20 mSec to sweep eyesight across that single modulated LED. So that's one thousand times slower than having a few images traced out on retina at 230 khz (4.8 Usec periods).

Nothing to solve, just sharing what I found: Manufactured fault in DMX splitter - Page 1

author_rank: Contributor
timestamp: November 22, 2022, 01:42:48 pm
content: HiI just thought I'd share what I found in this DMX splitter. -I thought it was interesting.For those not familiar with DMX, it's basically RS585 with a few extra specifications, used in stage lighting to control lights.The specification says to use 5-pin XLR connectors, but most cheaper gear uses 3-pin XLRs with basically the same pin arrangement as pro audio so microphone cables can be used.Pin1 = Shield, Pin2 = Data+, Pin3 = Data-Typically light units get daisy chained in parallel from the main controller, with a termination resistor (120 ohm) at the end of the chain.Obviously there is a limit to how long these chains can be, so that's where boosters & splitters come in.Anyway, so I bought this Beamz 8-way splitter for a show I was doing.https://www.beamzlighting.com/product/dmx8-splitter-booster-8-way/It has (or is supposed to have) a handy switchable termination resistor built in on it's input.I noticed that the termination switch wasn't working as it should, but it's an easy thing to work around by using an external terminator (like you would with any other piece of gear). But I was curious what the problem was, so after the show, I opened it up to investigate...-see picsWhat I found was that functionally, the switch & termination resistor were across power & ground, instead of across the DMX differential pair.

content: I guess, the most obvious explanation is that first, the silk screen on the front panel was printed with the 'PWR' & 'DMX' LED labels swapped. Then during assembly, that could be corrected by reversing the order of the leads between the main board & the little board with the LEDs & switch. -that fixes which LED is which, but unfortunately also puts the termination on the power instead of the DMX lines.So an easy functional fix for me would have been to just reverse the order of the leads again, but the labels on the front panel would then be swapped again (Red LED would be DMX & Green LED would be PWR). So instead I opted to change the routing on the small board, as per the following picture, which fixed the problem in a way that I didn't have to re-label the front panel.

Powering up means each adjacent row is glitch - charged high, next low, next high, next low as these sense amplifiers are turned on for the first time.

Any insights on India WPC certificates for GPS antennas? - Page 1

author_rank: Regular Contributor
timestamp: November 08, 2022, 08:11:33 am
content: Hi all,We develop various electronics products, some including GPS functionality. One of our key markets is India - and going forward, we will need to be able to export GPS antennas together with some of our products being shipped to India.In this regard, we have been told that it is necessary to have a WPC certificate for the GPS antennas to avoid customs clearance issues.An example GPS antenna we might export is the ANN-MS-0-005 from u-blox.1) Fundamentally, we struggle to understand why a WPC certificate is required for GPS antennas. These are passive receivers, which do not radiate. For the same reason, no other countries seem to require a certificate for GPS antennas. Do any of you know if it is indeed correct that a WPC certificate is required for all GPS antennas, or are there some exceptions?2) If a WPC certificate is required, do you know what specifically is "tested" on the GPS antenna? We would like to understand this to determine if e.g. the antenna linked above is likely to go through the test.3) Do any of you know of existing GPS antennas similar to the ANN-MS-0-005 that can be sourced from EU which are already WPC certified?Any insights on this would be really helpful!

content: I don't have a dumpster room like Dave, but when driving around you may sometimes find offerings left by the kerb - which is essentially saying "free if you want it". (While common many years ago, this is technically "dumping" unless it is an organised waste collection - but it still happens.)As it happens, I came across a toy ride-on backhoe - the same as the one shown - that seemed in pretty good nick, but there was no charger to be found. So I took it back home and charged the 6V (4AH, I think) SLA battery to see if it worked - and everything did! It has sound effects and plays music as well - not great quality, but quite loud.Current charging arrangement is - connect a plug pack which goes straight to the battery. I'd like something a little better controlled, so unattended charging does not result in premature battery degradation.I've had a look around at various options from pre-built modules from China to a DIY lash-up and thought it might be worth asking here to see if you have a favourite approach. The solution will need to be pre-set as it will be placed inside the toy, with no access. Power supply will be one of the 12V plug packs I scored from Jaycar.So ... I am interested to learn: How wouldyoudo it?

content: I thought I would take a look out further from my sector (financial). Thought I'd look for IoT and embedded jobs in the UK.I found plenty, seems very active, lots of new startup as you would expect.Then the music stopped with a Srrreeeectt across the vinyl and I looked at the salaries.They have roles for 10 year experience Principal embedded C programmers and they are offering... £45k. What? £45 wouldn't buy you a very good "Senior" i the financial sector, let alone a principal. I'm not saying what I'm earning, but when I get a call from a recruitment agency they are saying £70-75k is achievable with 10+ years experience in Java Enterprise, locally.Or maybe... glass door et. al. are only listing the vacancies people are finding hard to fill and the salary is why. Maybe I should check the in job reviews for standing salaries (if they publish them).

content: It's always been the case. Finance has the money, others areas don't. I worked for a bank and several of my colleagues had switched from embedded to financial. One even switched from working on flight simulators, the sort they train pilots on rather than games, because the money was so much better.

content: I'm a mid-level embedded programmer with an overlap to electronics design and I know these positions are paid less than for example Java, C# ...But if it is £45k gross then it will be low even for central Europe where wages are way smaller than in the UK.They are trying to attract someone from Eastern Europe or third-world countries.But at least here rates are not fixed but heavily negotiated in wild ranges.

content: I had two different colleagues programming embedded. One was a talented junior, the other one a seasoned senior embedded programmer.The first one went for web coding, the other one for C# and Java. The second one is a good friend of mine. He pretty much tripled the salary three years after the change.I don't know what is C# or Java programming like. However, I somehow think that embedded is difficult and requiring wide range of skills. For some reason it is paid rather poorly.

So far so good, but the weird thing is there is NO seller - at least on ebay- that sells from UK anymore - all of them now are shipping from China. So buyers beware.

content: How old is "really old." As late as early 1950's in many smaller towns, all calls were by an operator and most phones were party line (more than one household per line). If you picked up the phone and heard your neighbor, the line was busy. Billing for home phones was on paper as it is today, except you saw the charges by call for any call that was a "toll" call (i.e., out of your immediate service area). You could also call collect. That was useful when using a pay phone; otherwise, you had to deposit coins for so many minutes and the operator would interrupt when your minutes were up. In small towns where all calls were operator assisted, phone numbers might not be 7 digits. In larger cities, I don't remember a time without 7-digit numbers. My home # in LA was Atlantic (AT)2-8441. Don't bother calling that number and asking for me.In college, calls home (and to girl friends in other areas) could add up, so the "twanger" was invented. It was usually made from a bent clothes hanger. I kept mine for many years -- maybe still have it. You inserted it through the coin return box and held a certain lever inside the phone that would return any coin that was deposited to the depositor. Operators became wise to that scam and would listen for the coins to drop. We then added cushioning to deaden the sound. Addition of the lever-protected box killed that activity.
