@angelatlarge wha?
 
2 hours later…
03:01
slow night...
@coding_corgi We're waiting for The Stones to show up.
@ThePhoton ah
@ThePhoton hmmmmm........ rock isn't too cool anymore... maybe like electro pop?
@coding_corgi Rock is dead they say...Long Live Rock!
@ThePhoton you mean robot rock, by daft punk? das cool...
03:07
@ThePhoton eesh, hippies, god, oldschool
@coding_corgi Mods.
@ThePhoton hey! you lil tattle tale, worse than a little girl!
@ThePhoton okay song
this is better tho
Mod (from modernist) is a subculture that originated in London, England, in the late 1950s and peaked in the early to mid-1960s. Significant elements of the mod subculture include fashion (often tailor-made suits); music, including African American soul, Jamaican ska, British beat music, and R&B; and motor scooters. The original mod scene was also associated with amphetamine-fuelled all-night dancing at clubs. From the mid-to-late 1960s and onwards, the mass media often used the term mod in a wider sense to describe anything that was believed to be popular, fashionable, or modern. There...
@ThePhoton eh
@coding_corgi Nothing against Daft Punk
They kindof remind me of Devo:
MLM
MLM

@ThePhoton potatoe
03:37
@coding_corgi Looks like Nostradamus I ain't.
@angelatlarge Did something happen? He could have been on the flight, but not announced yet that he's in Cuba. Or is it confirmed he's still in Moscow?
@ThePhoton Neither, AFAIK
@ThePhoton But you'd think if he was in Cuba we'd know by now.

Wikipedia really does have everything you need to know:
In baseball, a strikeout occurs when a pitcher throws three strikes to a batter during his time at bat. Under Rules 6.05 and 6.09 of the Official Rules of Major League Baseball, a batter becomes a runner when a third strike is not caught by the catcher with no runners on first base or when there are two outs. The strikeout is recorded, but the batter-runner must be tagged or forced out in order for the defensive team to register the out. Thus, it is possible for a pitcher to record more than three strikeouts in an inning. As a result of this rule, sixty-six different pitchers have struc...
what is it with people on stackoverflow just randomly inviting me into rooms?!?! chat.stackexchange.com/rooms/info/9371/…
this is not the first time, etiher
@StaceyAnne Not the first time from Mr. Panchal?
@StaceyAnne Have you ever gone?
grEEts all!
US to Russia:

@rawbrawb Hallo
@angelatlarge, no some other guy last time
no, I'm too scared
04:06
@angelatlarge he wasn't a coder was he? he was an analyst.
@StaceyAnne :) Maybe you should change your name to "Stacey 'I am married, darn it' Anne"?
@StaceyAnne Bad things happen in those dark online chat rooms :)
@rawbrawb You are correct sit, however, a) I am not sure I know what an "analyst" is and b) that doesn't make a nice tag, does it?
@angelatlarge yep, might cause you to reveal your darkest ... deepest .... FPGA secrets..
@angelatlarge Or StanleyArnold
@angelatlarge in context and for YOU, it is appropriate... ;) I need an analyst
or should I say // you need an analyst
@ThePhoton @StaceyAnne looks like we have a new nick name! hey stan?
so all, what have I been missing?
@rawbrawb Battle of the Bands
04:16
@ThePhoton elastic vs. hair?
@rawbrawb I know some hair bands (Journey?) but I don't know any elastic bands. There is the Plastic Ono Band, of course.
@ThePhoton well , Devo used to have those plastic lamps shades on ....
@ThePhoton or perhaps an elastic band would be one that sprang back from adversity ...
@rawbrawb, haha
@rawbrawb I think it's "spring forward" and "fall back."
04:22
@ThePhoton now that was a stretch
@rawbrawb Don't rub it in.
where is @angelatlarge with his groans when you need him?
@AnindoGhosh I was just going to write " well I better sign off before mr. nitpicky language pedant shows up" karma vs. Dogma.
just in case you're sensitive tonight
;)
I'm very entertained by the new spin by the government machine around trying to discredit Snowden's revelations by discrediting him. Suddenly there's the whole bunch of people all pissed off because Snowden took on some project only to find out about constitutional excesses. The whole data monitoring thing isn't top of the news any more.
@rawbrawb Nahh, no nitpicking before coffee.
04:29
@AnindoGhosh nor recognition of a contextual turn of phrase either. Coffee giveth and coffee taketh away.
@angelatlarge That was absolutely hilarious.
@AnindoGhosh not the smartest thing to be talking about.
@rawbrawb Coffee waketh. Until then brain slumbereth.
@AnindoGhosh Thank you! I am glad someone (I am looking at you @rawbrawb) appreciates that.
@angelatlarge well, some one has to nitpick ...
04:31
@rawbrawb I'm not convinced that having an opinion violates international laws, yet. US laws are a different story, that the rest of the world is very amused about.
@rawbrawb You think India would extradite?
@AnindoGhosh I was referring to snowden revealing that tidbit, not a good strategy, like taunting a snarling dog.
@ThePhoton oh I see, I got at least two people misunderstanding my comment. I'm on a roll !
@ThePhoton Actually they wouldn't need to. A suitable small cash donation would get you the perp delivered in a burlap sack, no paperwork involved.
@rawbrawb Like a supervillain, he has to reveal his whole plan before dropping the girl into the lava pit.
@AnindoGhosh well he has "dissappeared"
@ThePhoton or the idiots that talk before shooting in the movies?
04:36
@ThePhoton India's very convenient to do "business" in, that way. One of the reasons that historically, the US "observer" (read: CIA) budget for in-country activity in India has steadily dropped from what it was in the 70s, I believe. Why keep a pool of operatives here, when it's far easier to "facilitate" through the lowliest LE on the ground?
@AnindoGhosh LE ?
@AnindoGhosh Also, I think we get along a lot better with India now than we did back then...
@rawbrawb Law Enforcement. Buying a beat copper for a burlap sack extradition would cost what, $200 for dead, $500 for alive.
Your guys are probably just telling our guys a lot of stuff they wouldn't have used to.
@AnindoGhosh as in Mehta's book.
04:40
@ThePhoton Yes and no, actually. Volume of operations has increased, volume of direct interventions (rather than through a cash-enriched indigenous proxy) have decreased.
@ThePhoton Do you get the sense that @AnindoGhosh sort of looks like a Mumbai street thug?
@rawbrawb Well, at the time when that novel was researched, it was slightly more difficult to buy LE. After the whole mess with the Commonwealth Games in Delhi, where the whole country found out that corruption and graft in the millions of dollars goes unpunished in India, the overall willingness of India to be corrupt has increased.
@AnindoGhosh The antithesis of "shining a light on corruption will make it go away"? Well there's no use hiding any more, ...
@rawbrawb He has the mustache. I think he might be a Sureno.
@ThePhoton or a mariachi !
04:49
rotfl
@AnindoGhosh there we go! a cross over hit, Mariachi Socal gang member in a Bollywood film.
we could call it "masala mariachi"
@rawbrawb Pitch it!
"murderous masala mariachi"
@rawbrawb "murderous masala" sounds like something they serve at a low budget dosa shop.
@ThePhoton maybe but more likely in one of those popular "indian buffets" that are all over the bay area. shudder.
anyway, gonna sign off now. Will catch you later.
04:54
@rawbrawb For some reason, dosa places are much more murderous on my intestines than other Indian restaurants.
05:13
@ThePhoton and @rawbrawb you people are EVIL! I was on a business phone call, and I had to struggle not to burst into laughter on reading the comments above. Finally I walked away from the computer just so I could finish my conversation.
05:37
good morning
Good night. (all)
05:57
@ThePhoton Good night!
@jippie Good morning!
This chat is so universal
30 minutes later, "Good afternoon @AnindoGhosh"
06:31
34 minutes later...
Arbitrary number of clock cycles later Hiya :-)
morning @AnindoGhosh
It's 1:30 pm here and I'm falling asleep. I need an afternoon nap
@StaceyAnne I won't tell your boss
it's all because there was a marching band at full volume outside my window at 4:30 am this morning
my boss already knows :p
06:33
I don't like marching bands
@StaceyAnne you got married to him :-p
haha, I was actually referring to myself, but he also counts
I think the neighbours are getting married. or something.

06:56
@StaceyAnne Huh? Where are you?

@Rev1.0 Why so blue?
08:04
Blue? :o
How did i get here? ;)
08:15
Woooho! I made my first touch button work!
I really liked this video:
 
1 hour later…
09:45
@abdullahkahraman, what did you end up using for the button?
@PeterJ Actually, I cheated on that part and used the one on the development board, TWR-S08DC-PT60.
@abdullahkahraman, I haven't done much with the Freescale range. I won a dev kit (different one) from Element 14 a while ago but apart from using the accelerometer to capture a bit of data on a project haven't really looked at it. What are their libraries and development tools like?
@PeterJ I hate using libraries, I don't feel good using them..
@PeterJ But IDE looks good.
@PeterJ It is Eclipse based and very usable.
@abdullahkahraman, I'll have to take a better look. Last time I went to use it I had a Win 7 driver problem and really just wanted to use the accelerometer again for something quick so used a different board. Although I've already got a fair bit of ARM based code / designs so didn't really see much that'd want to make me change away from what I'm more familiar with.
10:00
@PeterJ I just wanted to taste something different that Microchip, so I have made myself a fan of Freescale.. So far I am liking it.
@PeterJ Also, I want to dive into ARM one day. I saw that Freescale ARM micros are good. So, I thought it would ease my job if I learn simple 8-bit micros from them first, before going to 32-bit ARM micros.
@abdullahkahraman, I went off PICs because of the development tools originally (although they are a lot better now). The ARM range does tend to be more complex but once you get the hang and write yourself a good set of libraries you're set. At the moment I've mainly been using AVRs and Atmel ARM chips, plus some ARM9 / Linux stuff but just pre-bought SBCs nothing from scratch.
@PeterJ How hard was your first step from AVRs to Atmel ARMs?
10:18
@abdullahkahraman, not too bad, at first I used the IAR compiler because GNU was a bit less easy to setup and less examples were floating around but now there's so many examples and walkthroughs around it's really not too bad. In some ways it can be easier, because you tend to have a faster clock and more RAM etc. Things like DMA can be tricky at first, but once solved a lot of other tricky issues you can have with smaller micros go away.
@PeterJ Hmm, strange..
@PeterJ Did you work with USB?
@abdullahkahraman, yes, been a while since I've done it on the AT91SAM series but the Atmel libraries are good. I've wrapped them in a C++ layer for instance that means you can do USB CDC and serial comms using the same code at a higher level so it's quick to move everything between ports.
For AVR ask again in a month, just doing a PCB layout for my first AVR USB project at the moment.
@PeterJ How do you decide if a library is good or not?
@abdullahkahraman, just review the code, make sure it's easy to use and fairly modular etc. Plus I take the view that in the case of manufacturer supplied code while not necessarily perfect they've probably got hundreds of people using it so a lot of people testing it especially when it's been around a while.
@PeterJ Do you think it is a must to use manufacturer's libraries when working with USB and TCP/IP?
10:31
@abdullahkahraman, not really, but while they might not be perfect I think if you have the source it's more productive to start that way for more complex stuff. I have seen bugs in those sort of things, but I've also seen many 'workarounds' for situations I'd never have thought about just readings datasheets and protocol info.
@PeterJ So, I should start by "imitating" manufacturer's library :)
@abdullahkahraman, that's normally what I'd do, it's there to use and at least if you have problems there's probably others that have had the same problem and you may be able to get tech support from the vendor. Must say for less complex things (SPI devices and the like) I'm much like you and prefer to write my own libraries from scratch.
@PeterJ Oh, thanks, finally I am not alone :)
10:47
@abdullahkahraman, I'm in Vietnam (+7)
@StaceyAnne Wow, when did you start travelling? :)
@abdullah in august last year
so it's been almost a year. I go home in august this year
11:09
@StaceyAnne Oh, I thought you were going to start travelling in August this year :)
@StaceyAnne Have you been to Turkey?
oh, no I'm travelling again from dec - nov next year. and going to europe. So thats when I'm looking at turkey
I don't suppose anyone knows where you can buy cables about 150mm long terminated with these? They are thicker than the style Sparkfun and others sell for use on breadboards - these are for use with terminal blocks and think I've seen them before but can't remember where.
11:32
@PeterJ Approximately what diameter? Are these similar in dimension to banana clips, or more, or less?
@PeterJ Also, what terminal blocks? That might provide a clue.
@AnindoGhosh, no probably more like 1.5mm. I haven't really settled on a block yet but I was thinking something like farnell.com/datasheets/1493490.pdf. But really what I wanted was a PCB mount to bare wire interface that can be removed at the PCB end and is very vibration resistant.
@PeterJ Ahh... So why not the kind of spring-loaded terminal blocks used in speaker systems such as used for stage performances? The wire can then be either bare tinned, stiff single-core, or a connector such as you indicate.
Like this:
@AnindoGhosh, mainly because I hadn't thought of it ;-). What's that kind of connector above called?
@PeterJ Spring-loaded terminal blocks, and then there is the cooler one used in industrial electronics, they are called mating quick-release terminal blocks.
Let me find you the quick release ones, hold on. We've used them on some project, I'll just ask.
Here's another type we have used: The terminal block itself is removable from the PCB which has a pin terminal strip, and then the wires can be quick-fitted into the spring-loaded terminal blocks. news.thomasnet.com/fullstory/…
Ahh, here we go. Phoenix, that's the name I was trying to remember. Both mating pair terminal blocks, and regular (cheaper) spring loaded ones. phoenixcontact.com/online/portal/us?1dmy&urile=wcm:path:/…
11:55
@AnindoGhosh, thanks for the great ideas! Main thing I wanted to do is finish the PCB layout but I'm not pushed for space on this design so I might lay out pads for a few of those alternatives and can try a few of them.
@PeterJ The spring loaded ones get good customer feedback - the snap action feels very solid and gives confidence.
@AnindoGhosh, I remember seeing something similar on someone else had manufactured and they looked good. What are Phoenix like to deal with? I just noticed there distributor search only seemed to allow US zip codes and I'm probably only after 20 (maybe 100 long term).
@PeterJ You can find those terminal blocks, or close facsimiles thereof, on eBay. Let me check. We've never dealt with Phoenix directly.
Those are nice.
@PeterJ And some more conventional looking ones, quite cheap:
That last is probably what I would go for: Per-connector cost is really low, and being a bog-standard, old design, finding a second source with identical footprint and dimensions is not a problem.
12:15
@AnindoGhosh, thanks very much, I'll sift through them tomorrow but it's given me plenty of good ideas. On this design about 50% of the PCB space will be largely be wasted just to get it to mount in the enclosure (has a few large LED heatsinks and optics etc) so I can easily fit in space for several different options.
@PeterJ You're welcome. :-)
@Kortuk - By the standards of mod intervention noted before, please see this answer: electronics.stackexchange.com/a/73985/14004 <-- "This question is too broad and will likely be closed, so I'll be brief."

@coding_corgi Not much, I made a touch button.
@abdullahkahraman how?
@coding_corgi The touch surface is already on my TWR-S08DC-PTC60 board.. I just learned how to configure the software.
Actually, this is a deep topic and I do need to work more on it. But that is for another time, when I need to implement a PCB touch interface..

Q: Low pass Sallen-Key with variable cut-off frequency

user2069136I have a project that I would like to get some help with and would like some things confirmed. I want to construct a 2nd order Low pass Sallen-Key filter with variable cut-off frequency using one or two potentiometers (variable resistor). The topology can be found here: Sallen-Key topology. Low ...

For this question, I have searched the internet and I think he can use two LDRs and control their resistance with a light source(LED) controlled by an Op Amp, that way OP will not need ganged potentiometers
@abdullahkahraman You'd never get both LDRs to have the same R due to lots of differences.
@abdullahkahraman We would never attempt this in the analog domain. We'd go DSP. Overkill, sure, but there is probably other stuff that can get sucked into the DSP with a net increase in signal quality.

It pains me when I hear people say that our sites are unfriendly, or that we chase new users away. But it’s a hard problem, because our highest priority has always been the quality of content on our sites.  And it still is. We can’t lower our standards. We won’t.

But we have been working hard to make our sites more welcoming, reminding users that feedback can be clear and nice, and helping new users learn the ropes before they get frustrated.  And, as of today, we’ve completely overhauled closing. …

@rawbrawb I still want: Closed because you are in way over your head. And, Closed because the basis for your Q is stupid.
But I guess that would be considered "unfriendly". :)
@rawbrawb Now I want to go close something to try the new interface.
@DavidKessner And I'm sure certain someone's around here will have issues because it affects the purity of the site and "purity" is defined as PIC's and Op-amps and nothing else. Still it's step forward. AS for in "in over your head" I have many patents from that approach ...
@ThePhoton go pick one of mine ... I don't care. ;)
@rawbrawb Actually I just checked and the changes aren't showing yet.
@rawbrawb The guy who wanted to turn a truckload of sand into a GameBoy knock-off isn't gonna get any patents from it.
17:40
@ThePhoton That one was absurd. I can't tell if he was serious, or a troll.
 
2 hours later…

Is @rawbrawb in the house?
@rawbrawb This makes me so happy. I can't wait for it to start!

@ThePhoton just got back.
@DavidKessner most hallucinations are real for those immersed ...
Poe's law, named after its author Nathan Poe, is an Internet adage reflecting the idea that without a clear indication of the author's intent, it is difficult or impossible to tell the difference between an expression of sincere extremism and a parody of extremism. The law and its meaning Poe's law, in broader form, is: The core of Poe's law is that a parody of something extreme by nature becomes impossible to differentiate from sincere extremism. A corollary of Poe's law is the reverse phenomenon: sincere fundamentalist beliefs can be mistaken for a parody of those beliefs. History The...
@DavidKessner I hadn't heard about that, I like this aspect from the article "Any sufficiently advanced parody is indistinguishable from a genuine kook."
19:52
@rawbrawb Yup. There is certainly a lot of stuff that fits into that category.
20:18
Hey, I'm trying to get Microchip's example code working for using ECAN on PIC18F25K80. The problem is, the example code uses PORTD, while the 28 pin PICs (which I'm using) only have ports A, B, and C. I've tried to change it to PORTC but doesn't seem to work. Any tips?
@W5VO Oops, sorry. I'll try to keep my end up.
@rawbrawb What I wanted to ask is, if you ever deal with a product that's sold as bare die, and are there standard inspection criteria for bare die products?
@Littlegator What's a PIC? Is that anything like an LM555? <just kidding!>
...crickets...
@DavidKessner It's like a 28 channel 555
@W5VO Sounds dreadful!
20:30
it's actually just a bunch of jumpers that microchip pretends works as a microprocessor
@Littlegator See, Poe's Law (above). :)
@rawbrawb Inspection criteria that don't require buying a million-dollar inspection system.
20:47
@ThePhoton low volume production? because you can get probe cards/looms made to contact the pads directly. I have in the past built DUT boards with lots of circuits on board to eliminate a tester.
@rawbrawb Our vendor is doing probe testing. But the chips are arriving with what look like scratches in the top surface...
Also some kind of metal rub-off from the probe tips.
@ThePhoton on the pads? are these still on tape or in waffle packs?
@rawbrawb The scratches are in the middle of the chip, not on the pads. The probe nicks are on the pads. They are shipping to us in waffle packs.
And I don't know for sure what I'm seeing is scratches. But it looks like scratches to me.
@ThePhoton and they are the source of the die or are they singulating for you?
Also to the technician who was going to do the chip attach assembly.
@rawbrawb They are singulating for us.
We're buying singulated dice in gel packs.
I'm looking for some spec I can refer to and tell my assembly vendor to do incoming inspection according to that spec, and tell my die vendor I'm going to inspect that way and they should ship us chips that will pass.
20:51
Hmmm ... you shouldn't be able to scratch a die in the middle w/o some serious FU happening. Si3N4 is very very tough. unless it is polyimide passivated. Do you know the passivation?
@ThePhoton yes, incoming inspection and inspection standards are always a good thing. I don't know of a standard per se, you're looking for a visual inspection standard I suspect?
@rawbrawb I don't. They are SiGe chips. From a very large well-know SiGe fab.
@rawbrawb For now
@ThePhoton so given what I know, probably amplifiers etc. simpler V H frequency chips.
@rawbrawb very fast digital
@ThePhoton but simple right? just to clarify, visual inspection?
@rawbrawb Yeah. We're not going to build a new probe card.
20:58
let me see if I have this right. Wafer from fab, tested from fab, with die spots/red dots on dead die. Shipped to dicing vendor, who dice and waffle pack, drop shipment at dicing vendor. Shipped to you, then shipped to mounting and wire bonding vendor for COB. all done because of the speeds involved.
The vendors I've used actually have internal inspection standards that are referenced in the contract docs. I'll see if I can dig up some of them or I can ask around.
I don't think I'm getting drop shipments from the dicing vendor. My volume is very small. I think they have some diced parts in inventory in their shop (the chip designers'), and they are pulling them as needed for shipments. Like you say I then hand them over to a wirebond vendor for COB assembly.
The last batch was 16 pieces. I took them from FedEx and handed them over to the assembly vendor without opening the ESD/moisture pacakaging. The assembly vendor noticed scratches on two of the chips and returned them to me.
@ThePhoton sounds like a good vendor.
This complicates things, as it seems the designers are acting as a gateway. Did you contract them to design/supply or is it specialty product that they dispense to multiple clients?
@rawbrawb They know what they are doing. Unfortunately I think they missed a defect on a third chip, so I got a non-functional board out of the deal. On the other hand after they assemble the chip there's little protection so I can't really pin down where that defect happened.
But 3 out of 16 bad chips (if that's what it was) is too many.
@ThePhoton having inspection and standards at the vendor interfaces is sooo important. Unprofessional groups have issues with that, good ones demand it.
@ThePhoton esp. because of the knock effect of populating a board multipies the impact of a dead die.
@rawbrawb Yes, for sure.
@rawbrawb It's a catalog product for them. But volume is low.
21:07
I suppose you can't go to another source right? for dies.
@rawbrawb Not really an option.
I'm trying to imagine how someone picks 16 die from a tape carrier and damages them. Understanding that will help direct or help you write an inspection standard. thus the questions that follow.
good morning
size of die - dimensions, # pads, location of pads and size of pads. Is the wafer back thinned for COB purposes (normal might be 720 u die thickness, if 300 um thick we know it was thinned)
Is it possible to tell silicon nitride from polyimide visually?
21:12
@ThePhoton I can't tell you, truth be known, I've never used Polyimide so .... but since you have some bad die, you can test it, by scracthing, but then you may not get credit for bad die. Nitride is an ideal passivation, polyimide is softer, much softer.
@jippie did you mean die, rawbrawb die?
I meant size of die
was just fooling around a bit
time for bed for me anyway
@jippie size isn't so important, but speed is.
@jippie I know.
i didn't offend, did I?
didn't mean to anyway
@jippie not at all, was busy thinkerating.
I'm good at worrying
and the language sometimes ...
anyways
guys enjoy your evenings
/me is out
21:15
@jippie you too
@ThePhoton can you share a picture (from uscope of course)?
@ThePhoton you can just send it directly to me if you want rather than in chat.
@rawbrawb Sorry, boss in cube.
@ThePhoton so the issue is urge then? ;)
@rawbrawb these chips are maybe 2 mm square, 24 pads, they are thinned down, I thought 250 um, but it could be 300.
@ThePhoton typical picking procedures shouldn't be able to scratch so I suspected that.
80 um pads, IIRC.
@rawbrawb The scratches look like maybe somebody dragged a probe across the middle of the chip or something...I would not be surprised if these were manually probed.
or semi-manually.
21:39
@ThePhoton well, I'm a bit of die destroyer myself, I don't ship to customers however, die come to me to well .... die. So I know what that looks like. ;) pix?
looks like 80 um pads on 275 um pitch,
do you know are the die ball or wedge bonded at the COB place?
- this matters because of teh differences in ability to handle scratches.
22:06
@rawbrawb Wedge--unless the balls made by ball bonders have gotten a lot smaller since the last time I used one.
@rawbrawb sorry, no pix.
@ThePhoton Hmmm ... typically ball bonders (Au) are used on the smallest pads, wedge bonders need larger. But my brain is starting to work, and your's will be wedge because ball bonders (typically) need the die heated. in COB that is unlikely.
@rawbrawb gold wire
@ThePhoton don't have or can't have?
@rawbrawb Don't have, but also I'm not that ready to share...proprietary info and all that.
Also I already sent the chips back, so it's too late to get photos actually.
@ThePhoton fair enough. I'll look around in the next couple of days and aslo ask some people I know in the packaging industry if they can share.
if you need to contact me send an email to:

The Titanic exhibit was creepy, they had perfume from the ship they found you could smell, smelled like vinegar, then they had an EE section with resistors the size of an arm, so i knew it was outdated... ;P
Out of date EE section for sure
