content: There's no one storage solution that suits everyone. When I started out I had all of my parts in a few of those metal cabinets with the 3 partition plastic drawers.Now we use about 200 of the 600mm deep x 100 wide plastic trays that are often sold as small automotive parts storage. Parts go in bar-coded plastic bags (antistatic as appropriate) and each tray has a location ID on it so we can find it by looking at the location ID in the inventory control. In addition to them we have dozens of large plastic tubs (and shelving areas) to house all the bulky stuff - again, all bar coded and location ID'd.Buy what you think you'll need for now and some expansion, but realise that every so often you'll need to reorganise it all anyway.

I have one that is all resistors, one all caps, one all inductors, one all diodes, one all IC's, etc. I use a thermal label printer to label each bin (like "RESISTOR, 10k, 1%, 0805, 1/8W"). My labels are color coded so blue is resistors, yellow is caps, white is inductors, green is IC's. I also organize the bins in the cabinets, so smaller value resistors come before higher ones.Makes it very easy.For some larger parts, I buy those storage tubs. You can get cabinets to hold them if you have lots of them. Like this:http://c366610.r10.cf1.rackcdn.com/interlocking-drawer-storage-cabinet3567-.jpgIt's a bit of work to put all the components in the tubs when they arrive, but over the years I have probably 20 of those cabinets with 50-60 drawers each. It's nice being able to just grab what I need right away.For volumes of stuff, I keep them on the reels. I use anti-static tubs like thesehttp://thumbs2.ebaystatic.com/d/l225/m/mZHnD-EDZvqzdq5QQ3COhtw.jpgAnd I label them with the parts inside. I have all my 10k resistor reels in one tub, 3.3k reels in another, LED reels in another, etc.

Xbox 360 capacitors - Page 1

content: Hi guys this is my first post. The question that I have is. Does anyone know or have any thoughts on if fujitsu capacitors are any good? I have worked on a lot of Xbox 360s and I have noticed a huge occurrence of blown caps on the first gen motherboards. They are all fujitsu caps that are blown and usually located right behind the heat sinks within the air flow of the fan. I do replace these caps with the same make and model caps that are on the board. I guess what I’m really asking is am I really fixing the problem or is the problem the caps made by fujitsu?

content: Fujitsu (now Nichicon FP-Cap) are good capacitors.Any capacitor will die in the wrong conditions ... Xbox 360 is just hot inside so the capacitors overheat. Those Fujitsu polymers are rated for 1000-2000 hours @ 105c, and you double that with each 10c decrease.. so let's say 4000h@95c, 8000h@85c, 16k@75c ... what do you expect when the temperature inside is 60-70c all the time, to last years?

content: The heat dissipation was a huge problem in the older xbox 360 consoles - the "3 red rings of death" problem that plagued them was due to overheating so bad that it fouled the solder connections of one of the BGA packages.All three of my first and second generation xbox 360 consoles eventually had to be sent in for repair due to that problem (and my consoles were kept in very well ventilated areas).They generated a lot of heat, and were very inefficient at removing that heat. It doesn't surprise me at all that the older a unit is, the more likely that you will find failed caps in it - no matter what brand they used.I believe that the newer layout revisions have fixed the overheating problems, so your chances of finding dead caps due to heat stress is going to be a lot lower. The newer machines certainly run a lot more quietly, and seem to have much lower exhaust temps, so presumably there is higher efficiency hardware inside and probably better board layout too.

A quick look at the "error Fluke" - Page 1
Forum section: electronics / general

author: Excavatoree
author_rank: Frequent Contributor
timestamp: May 25, 2013, 04:21:10 am
content: For those who aren't familiar with SgtRock's earlier threads, the "error fluke" is an Fluke 87-V with the black ring around the inner current jack instead of the common jack. EDIT: SgtRock sent the meter to me so that I could examine it in person.One's first thought may be that the jack assy was merely installed upside down, that is, rotated 180 degrees. The picture below, "Jack Flipped" shows what would happen if that were the case. The hole in the front case for the V+ jack is a bit larger, so when the jack is flipped, the assy doesn't fit into the front case properly. See "Standard" for a close up of what it should look like.Because it isn't just installed incorrectly, the jack assy is actually defective (cosmetically). There has been no re-work to this meter, in my opinion. See "Soldering." These look like original solder joints.Finally, the "Front" picture shows the jack assy. It doesn't appear to have been modified in any way, and appears "as assembled" by the jack manufacturer.It does look to me like the vendor sent a bad jack assy, and Fluke didn't notice. I suppose later quality control steps are concerned with the readings, so there is probably a text fixture in the way. However, I can't imagine how it wasn't noticed by anyone doing even the briefest of "once overs" to be sure there are no glaring cosmetic defects.Not knowing the jack assembler's process, I'd just be stabbing in the dark as to what went wrong. I do wonder what the defect rate is. Do they throw away ones, tens or hundreds of these per month or year? Again, pure speculation.

Questions about Power Line Modems / Data over mains - Page 1

content: Hello to you who has entered this topic!I'm working on a little project that I have in my head and I was curious about some of the characteristics and snags etc. of sending data through mains.One of my main concerns is that the data I send over the mains in the house will also travel out of the house and through the powerlines. I'm not sure how far that the signal will travel, but even leaving the house could be a huge security breach with the application I'm thinking of. I also have a related concern with outside sources being able to send data into the house lines.Is there a way to isolate the signal to just throughout the house? If not what solutions could be thought up? Encryption would probably be the main solution. Any others?Another thing I see is that the transfer speeds on the chips I've been looking at (ST7538, ST7540) are pretty low. I was thinking about sending A/V data through the lines, or LAN which would both require significantly faster speeds than the 4800bps that those chips say they transfer at.Does anyone know of a chip that boasts faster transfer speeds? Or if it's even possible? I believe it is because there's a D-Link product that says it can transfer 200Mbps over mains. (http://www.dlink.com.au/products/?pid=846)How much of an issue would noise on the lines be? On most of these chips they usually have some sort of filtering going on.By the way! Hello EEVBlog people, first post. Like the community here.Also, kinda new to electronics tinkering, never been to school for it, but I like to consider myself somewhat knowledgeable on various categories of electronics/electricity.Thanks for your help!BAM5

content: All,I'm trying to get power to my test equipment, and would love to use a modular power strip. Is there any reason why I couldn't use thishttp://www.amazon.com/Conntek-55705-Housing-Receptacles-Computer/dp/B001IZ199M/with 120V? The only thing I would think is an issue is the protection would trip at half the wattage.Thoughts?

content: There is no reason you cannot use this in the US, except it might not meet US electrical standards. If it has any over voltage protection then it still would protect most equipment. The circuit breaker does not work on watts, it works on amps regardless of the voltage.

content: sure, I know it works on amps... but that means at 250V, it would trip at 2500W, where at 125V (making it easy for the math), it would trip at 1250W. Shouldn't really matter anyway. The DS1052e draws like 50W, my FG draws at most 35W, and my PSU draws 60W... so no real chance of coming close to tripping.Okay, cool. Think I'll pick up one of these then. Wish there were more options for modular power strips. =)Thanks!

Gone Retro Test Equipment... - Page 1

content: Don't know about other members but; my digital scope an ATTEN ADS1102 CML 100 Mhz BW, when used at low frequencies is annoying to use... yes I know it's low budget, and from China but has 1Gs/s deep memory with one channel used, and at higher frequencies it performs very nicely.However, the refresh trigger period at low Hertz has no adjustment, to advance the re-trace-trigger period; what happens is the time to refresh can be 15 or more seconds; also at Hertz periods, the screen trace has considerable noise possibly ? (Dither Noise), that reduces when going up the frequency spectrum.This might be just Y-amp noise ? but any anomalies occurring within the signal being designed or tested, is wiped-out within this noise... frequently I find myself returning back to my now 1970 Thandar 1" screen portable scope, just to check on the signal to see if it's clean or not.Anyway, due to these problems I am now going back to retro test equipment... e.g. a Tektronix Signal Generator 191 constant amplitude for RF work, and a Telequipment DM67 Storage scope upto 25 Mhz, that now days is the general ball-park I mess within.These equipments require repair and re-calibration, but it will be worth the trouble and enjoyment; the other side of the situation too, is that old 1960 Equipments are serviceable, down to component level, even the CRT while stocks are around.

content: Point #1) You'll have a similar experience if you go for something likethis. The problem is shitty, low-end equipment. A modern Tek or Agilent scope is a joy to use.Point #2) But... older, high-end equipment is much more affordable than newer, high-end equipment, so I'll have to agree. I've got a bunch of older stuff and a bunch of newer stuff, bothwithin my budget, and the old ones without question are my favorites.And I like the look of that Tektronix 191. That storage scope might be a bittoocrusty though. I do vastly prefer digital storage scopes to analog storage scopes, though I prefer plain analog oscilloscopes to both, whenever I can use them.

Seems to be a good combination for my uses. A new 100MHz digital scope costs less than my DMM. It was time.

Fluke Label Smear Problem - Danaher Down And Dirty? - Page 1

content: Greetings EEVBees:--Attention Fluke 87 V owners; Please be careful when cleaning your LCD display, particularly the retainer clip. I some black stuff on it, which I now belatedly realize was the cheap ass ink itself. See the attached picture. I was installing a new fuse in my latest Fluke acquisition, when I decided to clean the display before closing up, with some IPA, which I have never before, repeat, never had any problem with in cleaning any electrical test gear.--It has been speculated that since Fluke has been acquired by Danaher Corp., that Danaher would exploit the reputation while cheapening the product. That remains to be seen, but this latest problem does not make things look good. It looks as though they used Ink Jet printing technology instead of paint. I will be contacting the Fluke Suits again. Fat lot of good that will do me. I will probably get another letter from Fluke Customer Care, saying they cannot give me a replacement part for free, and resolutely refusing to acknowledge any problem with Flukes production line. I plan to ask them if all of the Retainer Clips have this problem, and not to ask for a replacement. I'll bet that they will contrive a way to ignore the question. Any bets?--I repeat be careful when cleaning you Fluke 87 and you never know what will smear from so much as finger oil.

Every single aluminum or tantalum electrolytic replaced with the best quality caps I could get my hands on.Turned it on and... goddamn CTT (Counter/Timer/Trigger) module won't initialize.So... what went wrong?I've been screwing around with this thing for days now (in between studying for finals, at least), trying to track down the issue. Found it today!What needed to be done?Swab of IPA on the underside of the trigger HIC.Must have gotten some semi-conductive debris on there when I had them all removed - one of the status lines was "shorted" (12 ohms) to ground through it.I spent the last week digging in the internals of this thing to find that it needed aswab of IPA.Well, at least I didn't have to replace anything.
