content: I can't tell what all's there on the Fluke item but it's part of a socket or a plug for an 8085 CPU. I think this piece might be part of one of the pods that is used with the Fluke 9010 Troubleshooter or one of Flukes other CPU testing devices. This piece would be for the 8085 pod. Like I said, I can't tell for sure with it in the bag but it looks like this is a replacement plug that goes on the end of the flex cable that's part of the 8085 pod that's used by the Fluke 9010. In the DUT, you unplug the 8085 CPU and plug it into the top of the Fluke pod. There's is a flex cable coming out of the same pod and it has a male plug on it (this part?) and you plug that back into the 8085 socket in the DUT and the 9010 can then control the DUT, test and read and write to each data and address line, read and write memory address and much more. It also checks the clock signals, the CPU power lines, etc. Go to Ebay and look up item 391856157636. That pod is for an 8088 but you can see the plug at the end of the cable. Fluke made a different pod for each CPU but they all plugged into the Fluke 9010 which was the controller. In most of the pictures that you see of the pods, the male plug is plugged back into the test socket on top of the pod so you really can't see the plug.

content: HiAwhile ago I posted a similar question but then I did not know the correct name nor did I have a pic.As you can see a normal screwdriver of any type or size will not work. I guess in a factory, a special tool is used.I wonder if a very small flat head could go in the tiny slot that is at about 7 o'clock.The only way so far that I have been able to turn the pot is using a needle nose pliers.My guess there is no easy way to turn them, but I thought I would try asking again.Edit - how about gluing a toothpick (cut to 10cm) on it?thanks

Ones that sit further down the centre have a more secure fit - but as long as you contact both sides and keep it straight, I've had no major difficulties.There might well be a proper tool - but I've not had the need to go past my little screwdrivers.

Can't remember but one is high impedence and one low.COMMON SENSE SAYS:3 RED wires = +20V carry more current3 Black = gndWhite wire carries 0.1Vots for some reason.Unless its a crazy design where 20V is some bias and the processor runs at 0.1V high current super high speed.

content: Yeah, I think Dells still use a barrel jack with a center pin, the center pin being a one wire connection that the laptop uses to identify what sort of charger is connected. At least as of the last time I dealt with one of those laptops, they had 65W and 90W adapters, and if a higher power laptop didn't detect a higher power charger it would complain and limit its rate of charge. Otherwise, you can leave the center pin disconnected and it will still work fine. IIRC, the one I had several years ago used an off-the-shelf onewire ID IC, although it probably held an ID that was specific to Dell.

My reason for wanting the chip is to remove complexity from software and to put the buffer outside of the micro. My concerns about just picking one are future availability and software support. Anyone have any experience with FDTI (politics aside) EVE products?

We had to keep the output until the drawings that were based on these calculations were released. Then typical engineer OCD resulted in me keeping those "forever". At one time I had a few rolls, each about two feet in diameter.Fortunately I lost them after less than a decade.

This is partly because of some of the things you mention. This topic is locked and I would ask that you do not seek to discuss religion or politics on this forum and if you are persistent which I'm sure you won't be you will eventually be banned if you wish to do so. While it is attractive to have such a levelheaded discussion with engineers from around the world as you point out we are from all around the world and people here will have their religions and views and if we start discussing them we will descend into a war of our own.......I think you missed the POINT entirely..... FIRSTLY, the (obviously construed) 'offensive' statement, being the 1st sentence of the last major paragraph, (which was quite tame anyway!), was NOT meant to be taken SERIOUSLY, and was but an EXAMPLE of the 'Sort of thing' than ONE may attempt to discuss as I mentioned, and being the simplistic 'point' of my discussion ?The FOLLOWING sentence where I said......The POINT being that no matter WHAT the context of the above 'sentence' is, and regarding what ever topic.....there will be countless answers here, from all walk of life !!!... and POSSIBLY, it will GROW to almost epic proportions,The 'Details'/'Nature' of the so-called 'Topic' had ZERO relevance to what I was talking about, and was only 'said' as a TOTALLY RANDOM 'topic' amongst 'Millions' of possibilities...... with NO specific relevance to anything on it's own xxMy ONLY point being, is regarding the diversity of responses to ANYTHING mundane, in this wide world we enjoy.....HOWEVER.... your 'attempt'/'reasoning' for Censorship has/had killed the whole process !!!Havea good day Simon....

That reminded me that I wanted to get one and bought a 10L model for 124USD off ebay.Are these bad for electric motors? The two thoughts I had was they could break apart epoxied windings or otherwise vibrate them enough to wear through the wire coating.Are there specific things that should not be cleaned with them? I just read an old thread here about not cleaning PCB's with crystals. Is it dangerous to stick you hand in one when running?

content: Leave it in long enough and what happens to aluminum foil will happen to the printed circuit board which will get an "etched" look. 10 minutes is at the upper range of time that I would consider reasonable. If scrubbed first, just a minute or two should be sufficient.The obvious precautions for washing boards still apply. Submerging unsealed switches and potentiometers is not a good idea. Precision trimmers are usually sealed with little o-rings so they are safe.An air compressor works well for initially getting the cleaning solution off of the board and out of cracks and crevices.

No Windows Store, UWP is barely a thing, notifications aren't really used, Cortana is gone, there are no forced updates, and I'd imagine it would run a bit faster too.Besides that, Windows 7 is still loved a lot, and Linux is something everybody suggests, but nobody actually uses for software support reasons.I know this is the answer you don't want, believe me I have made forum posts where I had to ask many times to help me fix the problem instead of just telling me to do something else (I use Turbo C, Stack Overflow is a frigging nightmare), but that's pretty much all the advice we can give you. Windows Store will continue to bug you, Windows 10 will continue to spy on you, and Microsoft will never change.Windows 2000 was the height Microsoft never reached again. A rock solid operating system with brain dead simple UI, and software support like crazy (when it was still supported). Every single release after that perpetually sunk into the ground. Server 2016 for me is actually really good, but I have that because of a special deal with Microsoft, and it's not something that is easy for most people to get. If you need to use Windows, Windows 7 or 2016 is going to be the best idea.

Is that a reasonable approximation of how fast you bike? If not, do the math in the other direction: 29 km / 18.3 km/h = 1.58 hours, except change the speed to your speed.If you were walking at 5 km/h instead of riding, it would be 29/5 = 5.8 hours.If you're math challenged, I'm sorry.

I can do 18 miles in approximately an hour and a half, so I'd say they're about right, but it will depend on the bike, your fitness, and how many hills there are.I live at the top of a hill, so usually getting back from somewhere takes considerably longer than getting there.
Bluetooth audio behavior on car's HU - Page 1

timestamp: February 10, 2018, 06:33:17 am
content: I've noticed that my phone (iPhone SE) doesn't behave the same depending on which Bluetooth receiver it's paired with, in particular to the notifications sounds.In my car, I've installed a Kenwood Excelon KDX599 and when paired, my phone will not ring or ding when I receive a call, text, email, etc. the HU will make a ringing trough the car's speakers when a call is received, but will not do anything in the event of a text message, email or other pop up sounds. My phone itself will still buzz like it would without being paired, just no sound at all.In the company truck (2018 Mercedes Sprinter), my phone will actually make noise as if it wasn't paired for everything but a call. This is much better since I can hear if I receive other notifications such as emails, text or messages. I can then pull over and take care of it rather than checking my screen now and then when I'm waiting for a reply or mail to come in or again when I'm on the road and a client sends me a text (like service call or last minute thing).I'm wondering if this behavior can be configured in the phone or if it's hardcoded into the receiver.Anyone has experience with such thing ?

content: So, for cars an BT, there's two bluetooth "profiles". One for handsets ("HSP"), and one for music/multimedia ("A2DP").HSP deals with voice-call stuff, like ringing, letting you "pick up", ending the call and of course the call audio (fairly low quality audio, so you don't want to play music over this)A2DP deals with music. It gives a higher audio-quality, lets you pause/resume, skip tracks, etc. But it is not used for calls.To me, it sounds like your Kenwood supports HSP+A2DP, but your truck only supports HSP.In Android, from the bluetooth settings, you can turn off A2DP (but leave HSP enabled) for individually paired devices. Maybe the iPhone will let you do something similar.

If the acrylic is not discharge after electron beam exposure then it would have a permanent negative charge. Spinning this acrylic would mean spinning more electrons than protons as it has extra electron stuck in it's crystal matrix. That should lead to a rather impressive magnetic field at just 2 or 3 RPM considering the drift velocity of electrons at 100 amps in a thick wire is only a few m meters per second . It all depends on how many electrons are stuck in the acrylic. Hmm.

I think it was first used in the 1970's.It is a mature technology by now.The website is:http://www.cochlear.com/wps/wcm/connect/au/homeThe CP920 is here:http://www.cochlear.com/wps/wcm/connect/intl/home/support/cochlear-implant-systems/nucleus-6-system/warnings/cp910-and-cp920-sound-processor-warningsThere is a lot of information and some videos.It is good technology. Cochlear have a range of products so I guess the doctors have chosen the 920 based on your friends particular issues. It could be there are alternative model choices available that might have advantages.

My normal full-time hobby was usually videogames.I have lots of parts and stuff so there's no shortage of little things to build for month's I'm sure. And there's ton's of course work to learn.I really wish I lived somewhere were people fix electronics rather than just ditch them. There's not much 2nd hand stuff to repair, or find and scrap, most people just send it right to the dump. And I don't have a car so most stuff is too far/heavy to carry home.I'd be nice to turn this hobby into money. But China can make 99.999% cheaper/ faster. And no one repairs stuff. So until I master a lot more stuff, I have no idea's to sell as products.I do feel like I've abandoned my games, LOL, like unfinished business. But this is a much better hobby for now.

Even if it's just a junked craigslist find, fix and flip is always nice.Even appealing to the less EE and more CS side of things and offering to do up people's PCs can often just be a way to get into people's minds for other tasks.Just one piece of advice. Before taking on a job, be entirely sure you can do almost anything and everything needed to repair the machine if it's repairable. People don't like being told they wasted a load of time and your money to go nowhere.

This topic is locked and I would ask that you do not seek to discuss religion or politics on this forum and if you are persistent which I'm sure you won't be you will eventually be banned if you wish to do so. While it is attractive to have such a levelheaded discussion with engineers from around the world as you point out we are from all around the world and people here will have their religions and views and if we start discussing them we will descend into a war of our own.

Look, my TV appears to be fixed but will probably set my house on fire. I'll just share this on YouTube."Does anyone have any idea how this will "fix" a flickering backlight? How can cutting a jumper magically fix it without causing more issues? Surely Samsung put the jumper in there for a reason.

Can't find the original source.Don't think I could ever follow advice like this! I'd want to know what's making it flicker and deal with the actual cause. If it worked before, something must have failed. Cutting a jumper seems like a silly thing to do to "fix" a TV, epsecially when it's cutting a jumper on the power supply board.
