Not a bad solder joint this time. So, after doing some searching, I cant find a good replacement, so this is where you come in. Does anyone know where I can find the 10k version of the POT in the picture or something extremely similiar? The pins have to be in the same location.http://www.ebay.ca/itm/50pcs-B50K-aper-pot-Panel-Mount-RK09L-Series-POTENTIOMeter-switch-3704-/291119635734?pt=Vintage_Electronics_R2&hash=item43c8151d16Preferably not 50pcs, I only need one.

If I cant find a suitable replacement, these two speakers are as good as scrap, dont care to jerry-rig something.

Recently, I've been frustrated with the slow bloated feeling of Swype so I thought I would give SwiftKey a try again. So far I'm much more impressed. It seems much more responsive and at least as accurate as Swype. Frankly, it feels a bit like what Swype had to be before it was taken over.Link :https://play.google.com/store/apps/details?id=com.touchtype.swiftkey

On the right side shows up the search page of the webshop.Maybe this (or a later version) is useful for some of you.It can import partlist from DipTrace ASCII and CSV, and support LomEx, DigiKey, SOS electronic, Mouser, Farnell / Element14 webshops.This is the first alpha release.

He would bark, growl and chew on the fence gate to try and get at them. It didn't take long for them to avoid the house. Fast forward to present day. Current wife is a bible scholar. She loves to invite them in. Same result as with the dog without the barking, growling and fence chewingCurrent dog defers to wife but I still have issues with the barking and growling.She just taps me on the nose with a rolled up newspaper and I behave.

content: The story goes, this guy is caught by the cops, parked beside a cadaver that seems to have been hit.So the cop arrest the guy and charge him.The guy claim he is innocent, that the cadaver must have been there before he parked and that he didn't notice it.It goes to court, and the judge finds him guilty of murder and condemn him to die on the electric chair.They strap him on the chair, pull the switch and the guy still lives. So they check their circuitry, and all is good.They try another time, and the guy is still feeling great.So, they release him on the basis that it was an act of god, that the guy must not have been guilty after all.Question: was the guy too good a "conductor", or too poor a "conductor"?NOTE: in French, conductor means conductor, as electrical conductor, but also driver, as in car driver ...

PCB Reflow Fumes... - Page 1

content: After years of hand soldering PCB's, I finally decided to buy myself a hot plate and lead free solder paste to try reflowing my boards. In my first try, I liquified the board into black goo and generated quite a lot of fumes because of too much heat. In my second try, with a thermocouple this time, the board stayed in tact and the reflow was successful, but still unleashed very, very unpleasant smell (not the usual flux fumes!).Is it always like this? Does PCB's produce this very unhealthy smelling fumes every time it's subjected to lead free reflow temperatures (240C in my case)? If so, is it dangerous like my nose suggests? I really don't want to get lung cancer from this... By the way the PCB material is FR4.Thanks in advance!Update: After some googling, apparently burning PCB's gives out highly toxic fumes... Well that's something new and very very important...

timestamp: June 07, 2014, 10:45:54 am
content: Hi allBasically, the DMM in the EX1200 switching unit/DAQ (I think the model is EX1200-2165) does not have a set of bus commands such as SCPI, seems it can only be controlled by its own software or a program incorporating its IVI driver, which makes it a pain in the arse to program in a calibration environment such as Fluke's Met/Cal. It can be done, but I would have to get write external programs in C/C++ and run a Met/Cal command to call the program blah blah blah, long-winded...This however gets even more complicated if the unit needs adjusting. The proprietary software provided has a cal/adjustment routine requiring specific kit, which we just dont have, so I want to write my own program, but I can find no reference to calibration commands in the manual, only the basic setup commands using the IVI driver. I need to be able to access and change the cal factors, etc.Any thoughts anybody?Also worth mentioning that I am new to IVI drivers, only ever dealth with programming in old proprietary GPIB commands and SCPI, and my C++ knowledge is limited, but I was trying to make this a project.Thanks

content: The "ceramic PCB" is the RMS converter hybrid (Fluke P/N 537209). From a google search, I think the 473777 chip is a differential-output opamp. I suspect it's all made of unobtainium.

timestamp: January 06, 2012, 02:44:04 am
content: I noticed that the power connections matched that of a common LM358, so with little to lose, I just tried one. It sortof works - the reading increases when the input increases but it is uselessly nonlinear. (That chip is near the output of the module, so I guess it takes the square root or something.) Looks like time to replace that module with a LTC1968 circuit since the rest of the meter is in good condition. (The previous owner even replaced the batteries! I replaced the constant current charger with a smart charger so it doesn't overcharge the batteries if left plugged in for a long time.)Some signal tracing with a scope also found a bad 4016 in the AC signal path, but the preamps were fine. My guess is that the previous owner must have damaged the 4016 and 473777 while replacing the batteries (most likely ESD or an accidental short circuit), then threw the meter away in frustration after it fails to turn on with new batteries. The meter works great on all DC and resistance measurements after I removed the shorted 473777.

content: I know this topic is old, but I wanted to put this information out here for other who have the same problem. The 'magic' Fluke 473777 is just a selected dual-opamp like an LM358 or similar. This same chip is used in the RMS converter in the Fluke 8060A for which a schematic is given on page 8-13 of the manual (seehttp://w140.com/sbcman/Technical%20Manuals-Main/Fluke-common/88XX-series/8860A_SM.pdf). This schematic shows the chip as a standard dual opamp. I haven't tried it, but I suspect that it is a selected LM358 based on the age of the meter.Hope this helps someone!-Matthew D'Asaro

content: Reading the thread on building a z80 computer makes me wish I still had a rack mount computer that my dad brought home one day.The computer was called an LP912 (I can't find anything on it on the internet) and it was used for oil well logging.It had inputs for camera and some kind of radiation sensor. He brought 2 home and neither worked, but through a combination of swapping boards between the two I got one to power up.I distinctly remember one or more Z80A processors and also a Z80 Dart. One of the chips I remember was a white ceramic package with a gold metal part in the middle. It had a variety of switches and LEDS on the front and a membrane keypad. There was also a small CRT, about the size of one you'd get in an analog scope.There was a text based menu and graphing functions which just displayed meaningless information because the required sensors were not attached.And for me at the time, the most useful function, was +/-12V and +5 BNC jacks on the front.I remember when selecting camera it would say something like "waiting for camera" and would pretty much be frozen until you power cycled it.I found this article:http://www.theatlantic.com/technology/archive/2013/05/the-time-exxon-went-into-the-semiconductor-business-and-failed/275993/Which makes me wonder if somehow the computer was designed by either Schlumberger or Exxon. It did seem to have a high percentage of Zilog and Fairchild parts in it.The boards went into a card slots and some had ribbon cables connecting them together. I think it was around 1992 to 1994 time frame when I had these and I think they were built in the mid 1980s.If anyone knows anything about this computer I'd be interested in hearing about it.
