It was some historical retrospective of Turkey vs. Britain in the first world war. At least I could navigate the beebs article all the way through. Al jazeera seems to have reverted back to a simpler style for their photo essays.

A tip - spilt and dropped SMD parts - Page 1

content: A package of 50 SOT-23 MMBF4393's arrived in the post today. They were on tape, as is normal, but the tape had been crushed in the post with the cover tape coming off and when I opened the packaging about 25 SOT-23 packages tipped into my lap and onto the sofa.Some were easy to spot and pick up but some were invisible on the black and purple patterned throw that was on the sofa. Then I had an idea, next to me was one of those adhesive lint rollers that you use to get cat fur and such off your clothes and furniture. It turns out one of those is ideal for picking up a whole bunch of scattered SMD parts. A couple of swipes and I had them all! Keep one in your toolbox.

Not sure which of them the 16B has, if it exists, but the 17B has all of the above and the 15B none.I have modded my 15B with extra 3D printed buttons for the first two functions, but temperature measurement is missing several ICs and a lot of passives, plus the end stop on the selector is wrong, (not to mention cal) so that is not worthwhile.Edit: ah yeah, I thought I put that here back when.https://www.eevblog.com/forum/testgear/fluke-15b-mods/The 12E+ he has there is definitely not the same board as the 15/17B though.

I know that some youtubers make hundreds of thousands per year, and that would be nice, but man this is just such a nice break for once, I mean, It's just such a massive amount of money, I haven't made close to that much on a monthly basis, hell, a two month basis.I have to wait for them to send a small deposit into my account and verify it, but then I'll actually have my account at the $0 mark for the first time in over half a year. I might be able to treat myself to something, who knows. It's just a massive relief, and yeah, I won't see this sort of money from adsense for another couple years I'm sure, but it's still nice.

Completely removed the Power transistors, and some resistors went up in smoke.I took the amp board for the tweeter (identical to the other one), swapped it to the position of the faulty module, and works fine, which shows me that it was just a fault with the one board.Does anybody have a schematic for the SEM712A or SEM715A (They use the same Amplifiers, etc, only the woofer size is different.ThanksPeter

If the change in quality is drastic, then you have found your culprit.Unfortunately the board I was working on set a few resistors on fire, and unmelted the solder on one or 2 of the power transistors, and toasted the board, so that one is on hold for now.

content: You havent tried routing the memory interface yet. That is where the fun part starts. Like it is on all 4 sides, not in order...While it is really upsetting, and I had my share of ST's pinout, I understand why this happens. First, on different packages, you want to keep some of the pins at a fixed location, and put some extra pins. This means those extra pins go in the middle. Also, keep in mind, that they are basically have limits, what they can do when packaging the device. You have pads on the die, and you have less than a mm to put those bond wires. There must be some rules that they need to follow.And why did they do the pads that way? Well BGA of course. For every QFP package we buy for our stuff, there will be 100 sold in BGA, and CSP size sold for the consumer market, going into something very small.

content: Let me tell you about that.... a couple of years ago we had a massive hail storm. I was actually driving in it, but on the fringes so I only hit rain - but it was raining so hard I couldn't see past the hood of my car, everyone pulled over, it was effectively zero visibility. It was quick though, as most really massive storms like that are, and I was able to continue on my way home. As I got closer to home, I started seeing cars with busted windows, and the ground looked like it has snowed in some places. Car after car with busted windows driving down the road. I began to fear for my other car, parked outside because this was before I bought my house with a garage, but luckily it had taken no damage. Most of my coworkers who were in the office that day weren't so lucky. Several of them saw this hail coming down and initially were laughing as they watched it bounce off cars out in the parking lot - until they realized THEIR cars were also out there. Three of them had their windows busted - side and back, not the windshield, as well as dents in the sheet metal that looked like someone went around smashing them with a hammer. One guy only had his car, a nice Audi, for 2 months, and because of the window being smashed and subsequent water damage all over the interior, it was declared a total loss. Insurance companies set up tents in various shopping centers to handle the volume of claims. No rental cars were to be found in more than a 100 mile radius. It took up to a year for some people to get their claim paid, and even this spring, 2+ years later, there were some people finally getting the roof on their houses fixed from storm damage. I don't know anyone around here with any solar panels on their roof to see if they took any damage, but with the general destruction from this storm I can't imagine it wouldn't also damage solar panels.

content: I rediscovered a couple of units that reminded me that I am capable of making stupid buying decisions !It all started when I saw a Rohde & Schwarz NRVS power meter being sold for spares or repair. The spares or repair category is a favorite hunting ground for me on ebay as I used to repair kit just for the challenge and enjoyment it gave.The unit arrived and was in pretty bad shape. The front panel was missing its Bezel and the LCD was smashed by what appears to be a stone impact. This was no surprise though as the seller showed all this in his auction.I was hoping to remote control the NRVS from a PC and so the LCD was not that important. I soon decided that it would be nice to restore the unit with a replacement LCD and bezel. After a few weeks of searching I found another 'spares or repair' NRVS in France. Its LCD was good and the Bezel was intact. It would also be a donor for parts for the other unit, or vice versa. I bought the French NRVS for £70 + shipping. Mad I know but the NRVS is a quality bit of kit and I already own several of the power probes that fit it as I own a URV35. The NRVS LCD is heaps of money so the French unit SEEMED a sensible purchase at the time.The French unit arrived and the front panel was intact.Long story cut short, on testing the French NRV5, it does not power up and appears dead. On testing the original NRVS with smashed LCD, its starts up but the damage to the screen prevents understanding what it is saying.I decided to transplant the whole front panel assembly including all PCB's from the French unit to the smashed LCD unit, hoping for a quick fix. No such luck, the original NRVS did indeed boot and the 'new' front panel and LCD works fine..... BUT.... the unit reports an absence of calibration data. The Lithium cell is intact and is fit for service so the unit has somehow had its calibration memory erased or the replacement front panel may hold calibration data that was lost when it was unplugged from the main board where the battery residesWell I quickly lost interest in the two NRVS units and did no more fault finding on them.So here we are, I have excavated the two carcasses from the lab where they will never be repaired. I now look at their poor shattered remains and wonder what I was thinking when I bought the first unit and then threw good money after bad and bought the second.learn from my mistake. By all means buy 'spares or repairs' units but watch out for those cases where a unit really is not worth the investment needed to return it to operation. I hate letting equipment die, but sometimes it is beyond reasonable help. Both of the NRVS units were incomplete when bought and real basket cases.Fraser

content: Does the buzz change or disappear if you disable vsync? With vsync on, the GPU power draw will pulse at the vertical refresh rate. That can sometimes cause inductors to vibrate. As long as it doesn't cause excessive ripple on the power rail, it's just an annoyance.BTW, that issue has been known to happen as far back as the FX 5000 series, especially with the cheaper cards that used open inductors.

In this instance, it is going into a museum. Heck, *the* museum for all such items. It will be available for the British (and world) public to see, understand, and appreciate. Hopefully they will be able to obtain the rest of the system and build a fully functioning unit.Value is a very tricky thing, and I do appreciate what you are saying. It had crossed my mind that perhaps the original seller was the widow of a WW2 code cracker, and deserving of more. On the other hand it may just have been a house clearance person trying to get scrap value. Without knowing the individual details of the situation, speculating on the morality is almost impossible.

timestamp: May 31, 2016, 09:01:53 pm
content: scale is not rust. a section of pipe that is rusting will not collect scale and vice versa; the rust is forming by an anode reaction, and scale forms by a cathode reaction. cathodic protection systems actually increase scale deposit on the metal that is being protected from corrosion, because the electrons that enter the water attract and concentrate the ions that form scale. To protect a surface from scale electrochemically, the impressed cathode becomes covered in scale and must be periodically removed and cleaned; the same way a sacrificial anode in a corrosion protection system must be periodically replaced.

content: Y'know, while I'm here, why don't I write an introduction post. This seems like a nice community...So my name is Russell, I live in the US. Oregon, to be precise. I have been interested in electronics since I was seven years old and took apart an old phonograph (much longer ago than I'd like to admit), and it's always been a passion of mine - I can't count the number of electronic things I, umm, didn't turn on. But I never got any support and wasn't able to actually do anything with it. So, I ended up going into computers, and chalked myself up as a failure when it came to hardware. It's not that I wasn't intelligent about it, I just couldn't make the required conceptual leaps.Until recently, when I found the Arduino (not an Atmel fanboy, just found something that worked for me) and started messing with a lightboard I had, ripping out the controller and making my own. I reverse engineered it, and actually succeeded (the lightboard works, and I even added a VFD display just for the heck of it and used a MAX232 to level set), and now I realize, hey, maybe I *can* do something with this. So I decided to start building out a lab and am picking up some equipment, and am trying to make up for lost time with all of the stuff I missed out on.I kind of miss the old days - when all of the components where through hole and dicking with things like soldering, etc., were in some ways way easier. These days, I find myself kind of lost with things like SMD soldering/mounting, PCB design, etc. I really don't even know where to start. But Dave's blogs are helpful and at least give me a direction to start moving in. I hope to someday build some cool stuff. I'll probably never be an honest to $DEITY electronics engineer, but I guess I'll give it my best shot. Nice to meet you all.

Then again, finding ink/drums for them could prove difficult.You mentioned the machine is a dyno, what sort of information does it print? Does it need a full A4 page or is it more of a "reciept" type output? If it's the latter, they still make new receipt printers with both parallel and USB ports, such as theEpson TM-T82II. You're likely to pick one of these "Point of Sales" type printers up brand new for far cheaper than a full blown parallel port desktop printer or dot matrix. Since most of these use thermal paper, you don't need ink, toner or ribbons.
