Vane (Volume) Air Flow sensor question. - Page 1

content: On older vehicles, it was common to use Vane (Volume) Air Flow (VAF) sensors. It is just a vane attached to a potentiometer. Reading the position of the pot, we know the position of the vane, and from the geometry of the sensor, the amount of air going to the engine.On some VAF sensors, the potentiometer, has a weird "geometry". It uses several trimmed resistors. The resistor between the wiper and a terminal will give a resistance that fluctuates from a value (that will rise with the position of the wiper) and a fixed low value (diagram bellow).Is there a advantage to do so?Alexander.

content: Automotive engine controls have come a long way from the early days of fuel injection. I think what you are seeing is an attempt to increase reliability by separating the resistors from the mechanical switching surfaces. The discreet resistors probably have better thermal and mechanical characteristics than a plain pot.I remember replacing throttle position sensors in older vehicles that were essentially carbon printed on a ceramic with a metallic wiper (like a cheap trimmer pot). The wiper would wipe away enough of the carbon to change the overall resistance and sometimes wipe the resistive carbon clear of the ceramic backing resulting in an open circuit. Similar open circuits in fuel tank gage sensors also were common; but they more often broke the wiper arm.

content: I think the hot wire air mass meters were a nice improvement over the old mechanical vane airflow sensors. I'm not sure why anyone thought a mechanical pot was an adequate solution for something like that, I've seen those TPS's fail that way too. A magnetic or capacitive position sensor would have been far superior and probably not much more expensive.

content: I always assumed it was done that way so that they could easily create a very customizable taper/curve to the relationship between flapper position and air flow. While I agree that the vane meters suck compared to the more modern mass air flow meters, I have found the old flapper meter, and the rest of the old Bosch analog L-jet system, very reliable for what it was.

content: Safety shutter, so that you cannot plug the standard round pin or flat pin plug into the middle of the outlet instead of into one or the other. With the typical use of these sockets in a US style system the device would actually work, as you have a path from line to neutral in those 2 connections, but the usage is not correct. The shutter is such that plugging a device into one will move the shutter to the open position, but trying to plug them in simultaneously results in the 2 shutter halves blocking each other, as both work in opposition so keeping you from inserting the plug. Plug into one alone and the other becomes open as well for later insertion.

content: I ordered one of these from Fleabay on Sunday afternoon, was delivered today(Tuesday morning) which I thought was quite fast!I have been over the unit inside and out and it's 100% genuine! The boards are Hakko, the IC is Hakko the wiring etc is all done exactly as in the genuine ones even down to the plate the earth wire hooks onto. Everything is exactly the same. The pencil itself is easy to see as genuine too. I have a copy one to compare it to so easy to spot the differences. I did notice on the Proto Pic website it says "discontinued" for that product number so maybe that's how they are going cheaper?I saw a few others that were so obviously clones for sure but this one had quite a few good reports of being genuine. I would highly recommend this seller to anyone looking for 1 of these, £118 delivered is a good price! The box inside the UPS shipping box came from one of the Hakko registered dealers in the UK too so I take it they are punting some cheaper on Fleabay. So long as it's genuine who bothers how it gets here right?I had a quick go today doing a few different things and with a couple different tips(i have a couple genuine ones too) I didn't notice any "great" difference to be honest. I would say it is a bit better feeling in the hand but nothing to shout about. One thing i will say is the end where the metal sheath meets the plastic handle doesn't heat up which is good, the plastic screw on doesn't come loose by itself either! I have yet to have a proper couple of hours soldering on it and maybe i will see some magic difference there. Footprint wise it is very small which is good too as I don't have a big desk...LOL...you know what they say about big desks?? BIG CHAIRS!!I didn't think that one through before I typed!Anyways.....All in all i am happy with it and would recommend it.

content: On and off, we discuss lead-free solder here and whiskers...I stumbled into this old TV show "Modern Marvels : Engineering Disasters" from History Channel. It documented the multi-day failure of the Galaxy400 communication hub caused by a short created by whiskers. That failure resulted in multiple cities in Northeast USA without tele-communication for days. It also documented some satellite failures as a direct result of whiskers as well. The "educational" part of the show has good illustrations of actual whiskers and physical information on whiskers (such as typical diameter/length, etc.).The segment onwhiskers starts at about 39:00(45 minute show). Almost right at the start (~42:00), it pointed out solder with lead greatly reduce whisker formation.Oh, bonus - There was a discussion about theEdmund Fitzgeraldon this forum some time back.https://www.eevblog.com/forum/chat/shipwreck-the-mystery-of-the-edmund-fitzgerald-no-depth-sensors/Thefirst segment of this episodeof Engineering Disasters happens to be about theEdmund Fitzgerald.
"Ten Days in Shenzhen" article - Page 1

content: This seems like it would be of general interest!http://www.karimyaghmour.com/blog/2018/01/ten-days-in-shenzhen.html"Much like other shopkeepers, the guy at the tape counter asked if I had WeChat. At the time when I first passed by his counter I still didn't have a functional device. By the 4th day, though, I had fixed this problem and I went back to several shops to connect with them via WeChat. TEGES mentions that WeChat is “handy”. From my point of view, that doesn't sufficiently highlight how crucial WeChat is. For there is one functionality not mentioned in TEGES that makes it a killer app for shopping in HQB: it's got live translation between Chinese and English. Now, I didn't figure this one on my own. At one counter where I stopped I started by asking if they had WeChat. The guy at the counter popped his phone and showed me the QR code for me to scan and connect with him, which I did. Then, as I had been doing before, I went to Google Translate to write my question and show him. Seeing what I was doing he said: “no, no, no, WeChat, WeChat”. I didn't get what he was saying at first. But he quickly showed me that he could type in Chinese on his phone, I would get the text in Chinese, long-press on it and get a menu that allowed me to translate it in English. And when I sent a message in English, he'd be able to translate it to Chinese. That was a revelation. From that point onward I was able to have very effective conversations with most shopkeepers when the discussion warranted going further than a couple of simple questions using Google Translate.Thereafter WeChat became central to most everything I did in Shenzhen, including keeping in touch with the companies I met. I returned to a shop where I had bought a few neodymium magnets a few days before for example. The first time around the guy at the counter didn't know any English. When I showed up and tried to talk to him he called what seemed to be his wife on his phone over a video call and just let me speak to her. She then explained to him what I was asking for. When I returned there, she was there in person. I asked if she had WeChat and we were able to have a constructive conversation from there on. When I asked if I could order from them for delivery back home, she asked me how do you ship magnets. That clued me in to something I hadn't realized before: powerful magnets can't just be shipped like other components. I knew lipo batteries required special packaging and carrier notification to transit properly, but I hadn't realized magnets were an issue as well. After some investigation I found that the marginal quantities I bought were a non-issue for my specific trip, which was my primary concern. That, though, didn't solve my problem if I wanted to use that shop and contact for ordering larger quantities later. I told her that I needed to investigate that upon my return and I'd let her known."

There's quite a bit of energy stored when running at nominal speed. Test chambers usually are buried underground or have wooden planks at all walls to absorb the shrapnel.

content: Quote from: grumpydoc on January 29, 2018, 05:54:04 pmCorrect. It's two valves (actually a MOSFET / valve cascode configuration) in parallel to provide a 100V / 2A pulse output into a 50 Ohms load.See the manual and some pictures inside:http://wunderkis.de/HP214B/An interesting detail is on P1130391: The coax balun used for output polarity reversal. The output stage itself can only produce negative pulses, so for positive pulses, one of the relays connects the either the shield or the core of the coax to output GND. The output stage is built fully floating with either its positive supply rail connected to GND (the tubes / valves run on negative voltage) or the valves anode connected to GND (for positive pulses), the balun taking away the high frequency stuff away from the now pulsing power supply rails. Quite interesting concept.

Extra confusion when a package is tagged as delivered when the driver scanned it before going off shift and its actually sitting in their van waiting until they have enough deliveries in the same area to bother dropping it off, but they had to scan it to keep up their metrics of XXX deliveries per day or XXX maximum hours in transit.

content: I have no experience with this particular model, but I'm using the wAP ac for over a year now. Runs without problems and is quite fast (note that Mikrotik actually gives you throughout results). It takes a while to get it set up (at least when you don't want to run in in a total standard configuration) since it gives you much more tools to configure instead of being wizard-driven. But OTOH it allows to configure you network the way you want.Mikrotik was actually a recommendation from people I trust to know what they are doing, and so far I was not disappointed. Powering via PoE was a nice plus (since the place where it stays has no power outlet, just Ethernet).

content: I installed one of those at home July last year. Excellent device.You are correct configuring them is a challange, they are so called prosumer devices. But learning a bit of networking can't be a bad thing in today's society.Due to the young age of Mikrotik, expect some bugs. Although I don't expect the bugs to be a problem with the simple situations you have at home. They also occasionally change how RouterOS works in a fundamental level, often to improve throughput. Some configurations will require maintenance in these occasions. (or you set the update channel to bugfix only)For easier devices you can try Ubiquiti.
I think my "bus pirate" is borked - Page 1

content: Hello.I own a Sparkfun "bus pirate", the 3.X version, specifically this exact model:http://www.hobbytronics.co.uk/bus-pirateI've owned it for 4 years, and it's been used all but a handful of times, and sealed up in a box for the most part. Last night I was debugging an ESP8266 module by connecting the BP in UART mode to the ESP8266 UART (3.3v, I always measure twice and check) - the next thing I know, is that when I ran the BP "~" self test option (and yes, the jumpers were attached, and yes, in the right places) I had 3 errors, 2 of which are "MISO FAIL" and "CLK FAIL"; I tried this on another PC also, same result.I've bought the updated 3.6 version from Amazon, to replace it, but what possibly could have damaged it on a 3.3v UART line? I'm always grounded properly too... I don't have SMD stations or reflow equipment, and have little inclination to spend *too* long repairing such a cheap device, but I'm very interested in what on earth may have happened to cause this. Oh, and I've got ZERO damage/shorts/scratches on it, it's pristine. Do they offer any sort of warranty or replacement service?Polite request: please don't point me to the links I can find in a Google search result when searching for bus pirate faults; this is a request for those of you knowledgeable in this area, I don't need references I can find myself with eyes and a keyboard, thanks.Thank you.

It's in good nic and does the job fine but I have heard people saying Hakko/Weller stuff is like night and day compared to the cloned irons. I will keep the Katsu as a 2nd/back up iron and use the hot air attached to it for SMD stuff. I am happy enough with the Katsu for any SMD work for now.The Katsu is my 1st iron so I've only used that and have nothing to compare it to. I don't do a load of soldering but will be nice to have a proper iron if they really are that much better.The Katsu uses a Hakko knock off iron and I use genuine Hakko tips in it and they made a noticeable difference to the cheap tips that come with the Hakko clone iron.That's a tip for anyone using the Hakko clone iron too by the way...get a genuine Hakko tip for it and see the difference it makes. Well worth it i'd say, the iron holds it's heat so much better and is much better to use. I got mine from PROTO-pic UK, well worth the extra ££!!
