content: I know this might sound trivial... but how do you keep track of things in the lab?I have a collection of parts/samples gathered over the years and I have no idea what I have got... I was thinking of cataloguing them or at least trying to sort them into some sort of sets...I was thinking of creating an Excel spreadsheet... is that what other people do? Or some fantastic bar code scheme??RegardsNivag

content: Depends on how many you have of whatever types of devices.I have a small collection which are basically bagged. Non static sensitive ones just end up in ziplock bags. These are grouped and dumped in rectangular plastic containers with a lids which can be stacked.My cataloging system is: "IknowI've got some TIP31Cs here somewhere...."

content: Quote from: NivagSwerdna on February 26, 2016, 11:21:17 amBecause 'things' come in so many sizes and shapes, as well as value ranges and numbering systems, you can't use one storage system or even ordering system for all of them. You have to be flexible.Some of the systems I use, starting from most disorganized up to cataloged systems:* Ziplock bags jumble-dumped in ice cream tubs and stackable cubes. The tubs are roughly categorized and labeled, the bags are not. This is mostly salvaged parts, that are not worth individually logging. Just tubs like 'medium size power transistors', etc. The ziplocks are only to keep sets of same parts together.* For tiny SMD parts, small ziplock bags stacked in order in small cardboard boxes. Label each bag with a marker pen. Btw, did you know you can buy ziplocks in all sizes very cheap in bulk from China via ebay.* Stackable cubes of stuff. Three different sizes of cubes (Ki-tab, and they stopped making them dammit, so no more available.) Many of these. Stuff like O-rings, big electros, small motors, toggle switches, IEC sockets, etc.* The small B5 size product manuals & CDs that come with lots of stuff - B5 ziplock bags, upright in storage cubes that just happen to fit them. Keeps all the receipts, warranty, docs, CDs, and my notes together for each thing.* Once I had a source of *many* of the flat cardboard boxes once used to contain PC motherboards. These are great, and I use them for a lot of stuff, on shelves and in cupboards.* Rectangular plastic kitchen containers with sealing lids (decor, etc.) Good where you want to be able to see what's inside. Tend to be expensive for what they are, so I don't have many. Use these for high value stuff, like logic analyzer lead sets. Just found out a couple of days ago that the ones I standardized on so far are also no longer available. "Easy Store, 5L" Bugger.* Parts drawer cabinets. Several different types. Long ago Dick Smith used to sell some really good ones, and I bought enough for a block holding all the resistor values. White plastic frame, red or blue plastic shallow drawers. Still use that. The rest are the metal frame and clear drawer kind.* For any components where there are a lot of different numbers/values and they are naturally sequenced, I use small manila envelopes, standing upright in boxes with partitions arranged to be the same width as the envelopes so they stand in rows. This is a really good system since it allows for inserting/deleting values without hassle. Write the part number/value on the envelope; it acts like a card file system.If the parts are static sensitive, wrap in al-foil before putting in the envelopes. DIP ICs can be stacked in 'blocks' then foil wrapped for minimum volume - can pack a lot of ICs in a small envelope this way, so the whole storage system becomes very dense.* For the really large stuff, there's the 'fruitboxes stacked in a room' method. Good luck looking for something.Overall, the worst problem with storage systems is that nothing good stays available. You'll start to use some system, then find you can't get any more of that container.As for cataloging, for the parts worth doing, my preference is plain ASCII text files. Just write lists in them, and use simple search tools to find stuff. No dependency on fancy installed software, it's portable, easily backed up, etc.Also allows for ad hoc notes on *where* stuff is stored too.I can take pics, if anyone is interested. But tomorrow.

content: Forget making an inventory - it's just too much hassle to create and update.My approach is to file stuff by function, in boxes that are small enough to sort through to find something reasonably easily. Divide into sub-categories as required to avoid over-filling.Size of box is actually quite important. Not too deep as this makes it hard to search and takes too much space. Long enough to take strips and shortened tubes, but not long and wide as stuff will get tangled more. Cheap enough to buy plenty of spares for new categories to to split a catergory when one box gets too full.Also when parts arrive, transfer into the smallest bag it will fit into to avoid boxes getting full of empty bag volume. Buy a range of very small grip-seal bags and some super-fine point permanent markersThese plastic boxes are the best I've found so far - 250x110x30mm, clear so you can see inside, and pretty cheap. Only downside is lids don't latch. Got them on ebay - sold for stickers apparently. Can't immediately find them now.For SMD strips of stuff like passives where you have a wide range of values, binders are the answer to keeping it all under control.For TH resistors, drawers covering a range of values each - the range depends on the sort of quantity you want to keep in stock, typically 2-4 E12 values per drawer.

Large quantities of parts such as resistor or capacitor sets are bagged and stored in the trays detailed below.Large partsFour large plastic trays each 70cm x 40cm x 15cm. A large card on the front lists the contents. I also have two of these trays full of tools, Three full of various wires and cables, one full of glues and tapes, one full of heatsinks and cases and one containing my stock of PCB material and perf board. All the trays are housed in a custom cabinet that doubles as a printer stand.Chemicals and PaintsStored in a fireproof cupboard.Test leadsThree convenient coat hooks that were on the back of the workshop door when I arrived.And finally...........................A large junk box that gets raided once in a while.

The label is very important to know where to search.Some parts are registered in a google sheet. Like Logic circuits, mosffet, transistors, electrolytic caps.The big advantage is that I can access the list from anywhere, on any device.No connection from the google sheet file to the location, but at least I know I have the part somewhere.The organisations keeps evolving as my parts amount increases.

content: If you're a one man band, keep track of parts on a spread sheet or data base is a fool's errand. You'll drive yourself nuts when you have to pull up a application, and log out a single mosfet - cause you think you're going to actualy keep track of it. Nope.Quote from: EEVblog on February 26, 2016, 11:35:15 amYea, I really would love it if people would stop posting things about Jim W's desk. You're not Jim W. Just cause your desk is messy doesn't make you like him. It just means you're mess like the rest of (most) of us. Let it go. (not pointed at Dave, just in general)Here's how I store my parts. I used what was available to me, and in that case was "Walmart" craft project boxes and wood left over from a fence I built. I cut the 5" pickets into slats and then did a little dado joint. I don't have a "how to on it" as it was all built on the fly. All you need is a table saw, wood, and some wood glue - that's it.I designed them to be the same size of a Craftsman tool box - to fit atop, and glad I did - as you can store tools in a 4 drwar took box, and parts on top. Makes for a very compact tool/storage set up. Since then I've bought a house where I have two extra rooms for a "lab" and another for 3D stuff/storage. So it's not so much needed - but still saves space. I've also labels each box since that pic. A thermal label-er is a must!Also Akro Bins. Get a few dozen that are about a 12x12 that stack, and a few 3x6's to load up on a shelf, and a butt load of little 3x4 that stack. For more random items - zip lock bags and milk crates.I don't have pics of my new lab - but it makes storage a pleasure.

content: That's pretty nice. I've got about three of those boxes that I use regularly (1x R's, 1x C's and L's and 1x Semis) and a scrap box. The rest lives in numerous RS boxes dotted around the house.I've got a *very* minimal count of parts. It's just not worth keeping it. I had about 200kg of boxes of shit lying around a few years ago and it was hell. You know 5000 count boxes of resistors I never use.

I keep one, but not to check out a single mosfet, lol.It is mostly for the more exotic stuff I don't stock often, because I need something for a project, order it, then forget about it because I am doing something else and then order the same part again because I have forgotten that I have ordered it already in the meantime!Like this I check my spreadsheet and if I see that the part I need is there then I first check my parts bins (and hopefully find it!) before ordering new stuff.

content: Quote from: george graves on February 27, 2016, 11:35:36 amIt works for me. I think the trick is not being so anal as to decrease quantities every time you use a part but just update or create the line when you receive parts. Order when you use a bunch and the number drops to what you are uncomfortable with. So for most consuming, I don't have to consult the spreadsheet at all. Only when I want to find an optoisolator (or insert a part you rarely use) that I haven't used in a while and don't quite remember where I put it. When I get a part for the first time I put the Mouser or Digikey description of it in my spreadsheet. That way I can search for part type rather than by specific part number

content: Quote from: george graves on February 27, 2016, 11:35:36 amYou shouldn't keep track of every single component. Just round to 10 or 100 pieces of commonly used components. Commonly used components can be stored in convenient containers so it is easy & quick to assemble prototypes but you need to keep track of how many you have -roughly-. Also having a database integrated with your CAD system allows to create a bill of materials including the quantities in stock so it is easy to determine which components need to be ordered. All in all a database can be a huge time & money saver when used right -even for a one man band-.

content: I use these numbered tupperware type containers, and keep an inventory of the contents in a document on Google docs.Most of these containers are about 4 x 4 x 6 inches and I also have a smaller number in triple and quadruple this size for larger components or projects in progress.They have a snap on lid and strong enough to stack as high as I'd ever need to. They're available in 'Home Store & More' branches in Ireland.I have other stackable cases with compartments for jellybean parts, also numbered and catalogued. My system is more than capable of handling couch feet in both plastic and wood should the need arise!Google docs is handy cos I can access them from any of my machines and they're searchable.

The wheels dont work so well on carpet.I really want to have a trolley for tools, a trolley for parts and a troll for test gear. It's annoying to keep moving scope/psu around if i need them near the work bench or near the PC. Will probably have the test gear trolley butt up against the workbench, so it can stay there most of the time.eg

And any part I'm low on, I drop a red shirt button into, and anyone that is ok, a yellow on. One that is over stocked a green one. Then in a few hours, you can go back and re-order all the red or yellow buttons. And when they come in, you remove the botton.

content: QuoteI take it to the next level, using a homemade li ion battery powered heatsealer with a 6" capacity. It's basically just a rectangle of 3/4" wood, approximately 4"x6", with a nichrome wire strung around one edge. The middle is cut out to hold the batteries, and a pcb with the timer circuitry and FET is slapped over that. I seal bags directly over my wood bench.I have a box of 6x8" poly bags on hand. But for most of my components, the faraday cage foil bags that Mouser/Digikey ships IC's in is ideal. When you seal this kind of bag, it is fused solid. And they look the same years later. The clear bags get cloudy over time. It makes everything look like more junk, and you can hardly see what's in them, anyway.For containers, I have a shelf of steel boxes with hinged lids, which are maybe about 7-8" deep and about 3 1/2" wide (about the width of the aforementioned metalized bags, conveniently enough). You can overstuff them and still squeeze them back on the shelf. Most what I store in these are SMD things, so I might have scores and scores of sealed bags in one box, and sometimes several rows of related SMD parts partitioned and labeled in one bag.... But honestly, most of the parts that make it this far are basically going to the graveyard/archive. Maybe 10% of this stuff sees the light of day, ever again. It's nice to know it's there, and waste not want not, and all. But the jelly bean parts I use the most are in a test tube rack, on reels on my reel holder, or on cut tape that is prearranged on little boards that are just wide enough to hold a piece of doublestick carpet tape with a little room leftover for a hand written label. Aside from some switches or other electromechanical things, most of the boxed and bagged components are somewhat like drawers full of mixed screws or bolts. If I'm desperate for a certiain item I know I have, I'll dig through the appropriate box for it. If I'm going to make more than a few, I'll just shop Mouser for the latest/greatest/cheapest that is more appropriate for my needs and/or volumes, anyway.Designing a circuit with certain components simply because you have 10 of them stocked away in a box from 3 years ago is not always a good idea. You might get sticker shock when you try to buy more. It might be out of production, entirely.

content: QuoteIt's not worth doing that, in my opinion. You'd lose a lot of time trying to keep track of every item. I thought about a similar idea myself, but didn't do it for the same reason. I doubt there is an efficient way of doing it without consuming extra time. I'm open to ideas though.The way I keep track of things is by boxing everything up and labeling them. Pretty much the usual way. Different sized boxes for various items. I keep the small stuff like transistors or capacitors in component drawers. Bigger stuff like chemicals or hardware parts go into transparent plastic boxes. I try not to stack too much stuff on top of each other. It helps to keep things visible for a quick inspection. Oh, and not to forget about a billion plastic zip bags of various sizes. Very useful. For example stacking a number of different value resistors in one drawer. That's about it.

content: I just happen to be cleaning out my biggest closet today when I noticed this thread. I looked around the apartment and best estimate is that I have somewhere between $300 and $500 invested in plastic storage containers - all kinds and all sizes. Close to half are 14 liter size, like an oversized shoe box, clear plastic with snap clamps to hold the lids on. Stuff is separated by type/function, and the boxes are all labeled. It's a lot like Mike has done.When I first got started with electronics I bought a few of those cabinets with many little drawers to store parts in. Eventually I realized it's best to just leave them in the bags they come in and started putting those in plastic boxes. That's when I started logging them in to a spreadsheet. There's still a lot of stuff not in the spreadsheet, but everything for the last 8 years or so is there. That's about as far as my "keeping track of" has progressed.

content: I put most components in one big spreadsheet with their datasheet linked to it. Lots of component drawers and component cases as the ones attached to this post (but in a bit better quality).In the spreadsheet, I note down either the component drawer or the case + location in the case. (see attachment; in this case, most of them are in storage case 13/14 - next to it is the location in that case) Also, for most components I note down the rated spec. Quite handy if you're looking to substitute some parts in an amp or such. Saves you time looking it up in the datasheet.I do not keep track of amount.. When I see some running low and I use it frequently: I order some..

content: I use plastic sandwich boxes - 89p for 5 from Wilko's (when I got them a few years back) - in a rack made from 6mm MDF which looks just like pigeon holes. The rack goes floor to ceiling and there are 207 boxes in each rack (now I have 4 racks).If you look at the problem to only solve 80% of the storage requirements the sandwich boxes do just that (for me).The racks were made by using a router with a 6.35mm cutter to put slots half way in the verticals and horizontals so they just slot together.https://www.amazon.co.uk/Plastic-500ml-Microwave-Takeaway-Containers/dp/B007SA1IE2is like the boxes which I can't find on Wilko's web site - not bad at 14p each thoughIf anyone's interested I'll put up a picture (which I haven't taken yet!)

content: It'll be tomorrow before I can send a photo but seriously, why such big boxes?With lots of little boxes you can write on the front what's inside and then you go straight to it (we put labels on both ends so it doesn't even matter which way round you put it back). You can even organise them into similar things to make them easier to find.With larger boxes, even with a spreadsheet, you still have to find whatever it is inside the large box.

content: Not if it's organized from the start. Let it get all messed up where in any given row or column you might find resistors, MOSFETs, opamps, capacitors, relays, etc - and I'd agree. If say one column is all resistors, another caps, another half linears and half logic, etc. it wouldn't be too hard to narrow down the area to look based on what you are looking for. Then clear readable labels on each box is another given. Worst case, you zero in on the column you need and have to scan down that one line of boxes to find the one containing the part you are searching for.I know this because the small parts drawers I currently have are willy-nilly and I can't find a darn thing, and there are still many empty drawers. I need to fix that, soon. My friend has about 2x the compartments of that but it didn't take me long scanning his labels t figure out the system he used to group like things together. Aside from misc. hardware, I was able to quickly zero in on a component of interest, and that was the first time I've ever seen his home lab.

content: Inventory and storage are like hand and glove -- they go together. A good storage method makes it possible to avoid the more tedious task of counting and inventory though having a periodic inventory isn't a bad idea either.I'm just about finished with my small lab and have Acro-Mils cabinets for much of my through hole stuff as well as connectors, pins and other such things. For equipment related storage I use three difference sizes of Sistema Kilp It plastic boxes to organize my test leads, cables and adapters etc.I have a video for this as well...Brian

content: Quote from: Chris Mr on September 12, 2016, 05:43:27 pmI use this freestanding shelf rack of plastic boxes method to keep most of my parts. I just don't have as many boxes.I keep the grid of boxes easy to look trough by sorting by rows. For example 2 rows are dedicated to ICs. All the labels on those IC rows are the same color to make sure the box does not end up in another row when you pull out multiple boxes. Then those IC boxes are labeled by the function such as "Opamp" "Memory" "Switching regulator" "Data converter"...etc. There must also be a misc digital and misc analog box for weird parts. Then next row might be discrete semiconductors that has a different label color.The problem i have ran into is overflowing tho. For example the standard connectors bin that holds things like Dsub, RJ45, XLR etc is really full. There are many connectors that go in there, plus they often come in tray packing that takes up even more space. Its not easy to split a overflowing box in to two more specific boxes since all boxes are already used and the labels have to be printed on my color printer to fit to the color coding.For projects i tend to just label a Digikey or Farnell box that the parts came in with the name of the project and then add stuff in to it. Also the date of ordering is written on to it so that i can go look at the receipt to search trough the list of parts when im looking for a part. When the project is done or abandoned the parts from the box then get sorted out in to the plastic boxes

content: Quote from: Berni on September 13, 2016, 10:55:58 amOverflow and new categories are the killer of all full-grid-shelving storage systems.To avoid this, for anything requiring boxes I just stack the boxes randomly on the floor, and large shelves in storage areas.For small parts with a lot of numerical values, I use this 'cardfile-like' system in the pics below.The containers are sold in hardware stores as 'under-bed storage'. Covers to keep dust out.I add rigid partitions inside using cheap (discard & offcuts actually) 3mm MDF board, just butt-joined with urethane glue. Held in place with tape and weights while the glue dries.The spacing is chosen to suit little paper envelopes, that can be bought very cheaply in bulk. For this I use paper ones rather than plastic, because they stay upright like a card, and you can write on them with pencil and erase if required.I have a bunch of these boxes in the loft, just stacked on the floor. Most hold through-hole parts, some SMD.The two shown contain small transistors and the other 74LS and 74HC ICs.Loose ICs don't pack well in envelopes, so for density and also static protection I bundle them in bricks wrapped in al-foil, that just fit endways in the envelopes. One envelope can hold about 120 DIP14s this way.The advantage of this system, is you can just insert new values with no trouble at all. Overflows are easily dealt with by just adding another envelope. And it can hold a LOT of different values, also sequentially sorted so ease of finding things is about as good as it can get. And you can write rough quantities on the envelopes if you care. No messing with computers required.The downside is the plastic of these containers is brittle, and probably won't last many years. You have to handle them carefully or they'll crack. I haven't broken any yet, but I know I'll never be able to buy identical ones in future.For bigger parts like large transistors, I just jumble-dump ziplock bags in stackable cubes and cardboard boxes.

content: That is a pretty good way of doing it.I use clear plastic tubs with no lids that i got at a hardware store reasonably cheap. In my opinion lids are time consuming and i keep my tubs on a shelf rack that has a shelf spacing just barely higher than the tub to keep the top mostly covered and it seams to keep dust out reasonably well.I like to keep my components in the plastic/antistatic bags that come from the component supplier so that i have the full partnumber and order code still on it. I am considering getting some of those yellow envelopes that you use for repacking things that come packed in a annoying way or for parts that i salvaged or got from somewhere.(So far i use zip lock bags for that but they are not the best to sort trough in a box)

I wonder why I do that. At some point I will go through the boxes of bits and make the latest project out of them instead of something more suitable - would keep me on my toes!

content: That chipeasy thing looks too easy for a human to scramble; those drawers would end up looking like the specialty hardware drawers at Home Depot and Lowes.Also, the parts are exposed to the atmosphere, and y'all know what that means.For small SMT passives, I use cryovials that have micro-QR code labels on the bottom and O-rings in the tops, and I keep 'em in 10x10 index boxes made for cryovials. I also have a few small cryovial work trays I can populate for projects. For small semis, I'm sticking with 2x2 and 2x3 antistat zip bags; they load nicely in slide trays. For larger items, well, I do it this way...
