Author DIY Noob Stockpiling Question
Muff Wiggler
so please keep it hush-hush but with the imminent completion of my Wiard/BugBrand systems and stepping away from commercial gearlust, I plan to finally delve into DIY this fall, after years of thinking about it, building the small project here and there, but never really diving in.

I'm going to take the next few months to set up a good work area, shelves, bench, parts bin, etc. Also will slowly be picking up the PCBs and Panels needed to build a couple each of the Best of CGS boards.

Plan is to be all set up by winter, and spend a few hours each day over the winter soldering and building and getting into a groove of spending a couple of hours each evening building stuff.

So here's my question - I'm sure it's been asked before and I apologize for not finding it, but I'm gonna be making a few massive component orders over the next few months. I hope to have more than I need of everything to be able to complete just about any project that I come across, without having to order project-specific parts (understanding that there's always gonna be the odd unique bit here and there).

I wonder if anyone has ever merged together the BOMs for hundreds of modular synth projects and been able to give a %age rating for how often components are used.

Actual question is here:

If you were gonna stock up on all the resistors, caps, transistors, diodes, common chips, etc etc etc in order to have an awesome partsbin for building a couple of hundred DIY synth projects, what would you order?

thanks
theglyph
CMOS (e.g. CD4XXX), OPAMP TL072/4, Transistor 2N3904/6, Diodes 1N4001/4148 are some very common parts.

You'll find them used in many of the CGS circuits.

I have a few spreadsheets I made to order parts for the first two best of panels and a hand full of other projects like the klee, Thomas White's LPG, the single 281 group buy boards, the 208 random voltage board, probably a few of fonik's designs, Thomas Henry's MPS, ryktnk's M185 and probably others I can't recall off the top of my head going back a few years. I wouldn't use them as a definitive guide, they probably contain a number of errors and a fair amount of discontinued parts, you could likely have a different preference as far as some parts are concerned, and the way I laid them out might be confusing as hell to anyone but me, but it might offer a place to start.
Muff Wiggler
thanks guys, and bf i'd be interesting in looking at that info. hell i should probably do it myself, just collect a shitload of BOMs and stick 'em all into one spreadsheet

at this point though i'm thinking at an even lower fundamental level.

like -

- should I just order a shitload of every value of resistor? 1000 of each one?

- do the above for every value of resistor in both 1% and 5%?

- order a shitload of every value cap? repeat for ceramic and metal film?

oops that's how green I am dude It's motherfucking bacon yo

Oddly enough, I actually did something like this, although this bill of materials might not be entirely accurate...

For s&g's, a few days ago I did up a list of PCBs for Zthee's 3 panels, plus a number of other PCBs, using just the parts lists provided in the various pages for the products.

Warning, this list is long, and is probably wrong too, with a few errors here and there.

This parts list more than likely missing potentiometers and a few other things.

Not a problem. I mainly wrote it for my own personal reference and curiosity, namely that of how much all the parts and PCBs would cost for the variety of modules I'm looking at.

Given that it's a night off (three day weekend, YEAH!), I'll whip up one for the "Best of CGS" Panels. Shouldn't take any longer than an hour or so. Do note though, that, that such will be a "quickie" version - I'll try and write up an actual proper one using Zthee's actual layouts this weekend (if I don't spend all three days playing EVE Online >.>;; ).

This list might be useful...

I'm sure there was another list like this someone on the sdiy mailing list made ages ago.

I like to have the following on hand..

List of doom for all three panels, once over, according to module info available here -> http://www.cgs.synth.net/pcb/bestofcgs.html

**Like my previous note on the seperate panel listings, this is only including what is listed on the BoMs for the various modules, so does not have the correct amount of jacks and pots**

....Odds are I'll probably look into making this list prettier, and easier to read (say, spreadsheet or something).

Think i got this of EM

If you were to build 162 modules from CGS, Jürgen Haible, James
Patchell, Oakley, MOTM and Tellun, here's what you'd need.
Probably not quite complete, but you get the idea.

Capacitors

Since all those modules are powered with +-15 V, no
capacitors actually need to be rated for more than 30 V.

BC547 through BC550 (resp. BC557 through BC560) are usually
interchangeable. I just got a bunch of the best grade (BC550C resp.
BC560C).

Resistors

All 14 W unless otherwise specified. Most don't actually need to be
metal film or 1% but those are so cheap now that it's not worth
bothering with 5% carbons. Mouser is not necessarily the best place
for metal film resistors in smallish quantities. They have 100 PPM
parts for a good price but their 50 PPM counterparts are 4 times as
expensive. Farnell sell 50-PPM Multicomp MF25 resistors for 0.038 EUR
each in quantities of 50, i.e. not much more than what Mouser charges
for their 100 PPM parts.

Tempco resistors

Tempcos are used to avoid drift in exponential converters. The ideal
temperature coefficient is around +3350 PPM. In parts lists you'll
find

- +3000 PPM. This is a little off but cheaper and easier to find. Best
reserved for filters and other places where exact tracking is not
critical.

- no value. Probably means +3000 PPM.

- +3300 PPM and +3500 PPM. This for oscillators. Resistors of the
exact coefficient can be found but typically have to be made
specially. +3500 PPM parts are available off-the-shelf from the
manufacturers and hence much cheaper in small quantities. Most
people seem to think +3500 PPM is close enough.

- should I just order a shitload of every value of resistor? 1000 of each one?

Resistors
Buy 1%. Forget about 5%.
100 of anything that starts with 12, 15, 18, 27, 39, 56, 68, 82.
100 of anything lower than 100 ohms.
1000 of 100k
500 of everything else.

Capacitors
Don't bother with Ceramic caps, except for pF values. Get COG or similar.
MKT more or less = polyester = metal film = greencap, so just get MKT.
Get 5mm pin spacing.
See what values are used before going crazy, unless you are either rich, or find them cheap.
100n and 10n are probably the most used.

Bucket loads of 100n (0.1uf) in monolythic ceramic for decoupling.

Don't bother with any "computer selected" mixed value packs. The computer usually selects the crap the company can't sell because no one wants them.
iopop
I would really recommend to add up the totals on all modules you plan to build in a spread sheet. You will learn a lot and get a more clear image of what you really need.

Resistors
Do not buy 1000s of each value. You'll end up with far too many unused ones. Sum up the totals in a spreadsheet and see which ones you'll really need a lot of. The sdiy list by widdly is a good staring point. A strategy I'm about to use is to buy 100 of each new value that occurs. It all depends on the suppliers price breaks.

Also if buying new there's no need spending money on 5% resistors. 1%s cost more or less the same and you'll not need to wonder if you use the right tolerance.

diodes
1n4148 are used everywhere. Mouser have a quite nice price break if buying 1000, in the end it will be cheaper than to buy 2x250.

Transistors
For a start buy 100 of 2n3904/2n3906/bc547/bc548/bc557 and you are stocked for a while. For Fets and others check the boms. I tend to buy 10 or 25 of each new transistor I do not have in stock, unless its some uber rare $2+ part .

Semis
TL071/072/074 are common. 100 of TL072 and 50 each of tl071/TL074 will keep you stocked for a long time. For other parts check if you find anything that really motivates buying many. 4017 and 40106 are quite common in the cmos family. If planning to build MFOS designs LM17000 / NJM17000 are common, buy 25 to get you covered.

Caps
I find caps to be the hardest part to keep on stock since there are far too many variables to keep in mind, lead-spacing, tolerances, physical dimensions etc. So, its usually best to look at the pcb / schema and see what really fits.

Some caps that are common includes 100nF decoupling caps both thru-hole and SMD. 10uF electros and on Ken's boards 47pFs.

Ken also provides the possibility to use caps of different lead-spacing (2-4M) on some places which is not common for other manufacturers.

Sockets
Buy 100 each of 8, 14 and 16 pin sockets of you favorable style (machined vs. low cost). Buy odd sizes on demand.

Trimmers
Expensive part $1+, buy on demand. Never found any good price breaks if buying 10 / 100 either. Also the same variable trouble occurs here as on the caps. Different pin-outs, multi / single-turn, physical dim. On some f Ken's PCBs he offer both pin-out types which is good.

----

Just to be clear I have a long term 'investment strategy' on SDIY and have no trouble ending up with $100++ worth of unused parts in the end. ymmv.

Thanks! I wanted such for my own records, plus mining in EVE is just so mind-numbingly boring very frustrating twisted (but somehow I tend to enjoy doing such).

...And nobody else had posted one that I know of. Still thinking about making a neater, sexier list though, potentially even with mouser part numbers (if I can learn a bit more, my old knowledge of electronics is, well, 12 years old now.)

I've done the spreadsheet thing- I'd send it to you, but it's like 17 tabs of pivot tables and random mutterings on the different kinds of capacitors. Pretty much drives you nuts if you want to do it right.

My first thought is on organization of the components themselves. Fortunately in my case, I have an anal-retentive wife who got some of those divider cases (available at your local hobby store for like 3$) and organized all of my caps and resistors (transistors and diodes come next). She then also labelled everything, so it's easy to find.

I agree with Ken above- just stick with 1% metal film for all resistors- and the kits from small bear are a good start.

For resistors get lots of the common values like 100k, 1k, etc and one of these

http://cgi.ebay.ca/MR25-Metal-Film-Resistor-Kit-1-1-4-w-E24-E12-Values -/360351764234?pt=UK_BOI_Electrical_Components_Supplies_ET&hash=item53 e6a38f0a

they are sorted out very nicely. If i notice a value running out i put them on my ongoing digikey or mouser order. that way i always have every E24 value below 1M in stock.

It is nice to be well stocked, you can get a board almost finished and have it waiting for its "special" parts

dont forget to get lots of whatever board connectors you need for your system, a nice wire stripper, solder sucker, MTA press tool, screws, brackets and all that boring stuff.

Yea, just get the kits man... also KEEP INVENTORY. I have about 15 cabinets of electronics components at home and w/o knowing what you have, you end up re-ordering over and over - it is wasteful. It may seem like a PIA but needs to be done if you plan on DIY'n electronics on a regular basis.

FYI, we have been developing a php-SQL online parts/equipment inventory system with barcode reading (we are using a ipod camera for now). The benefit is that the online version anyone in the world could see and read/search your parts. The local instances you can actually signout/in parts. Anyway, it's been my dream to have a lil inventory software available to everyone for free and hopefully ppl start hosting their inventories online... i'm sure there's tons of DIY'er in my area who may have needed just a single part to complete a design and I may have had it... and visa-versa. We plan to have it finished by end of summer and will release it open source. w00t

One thing I found really really helpful is you can get 2500 1% metal film resisters on ebay for ~$15 - $17 (US) which is usually 50x of 50 values. What I do is buy a lot from various people as each 2500 from each person usually includes different values but you still get your 1k, 10k, 100ks and so on so you end up with a lot of those (which you will blow through like no one's business). There was even a guy that had for $20 US 10x of 167 values. It might be worth getting one of those just to pick up random values.

Lastly, there is a seller called thaishine, I don't know if there is and difference shipping to CA, but they ship free, and fast. 10 TL074s for 4.99 with free shipping. At least to me, that's a good deal. Plus they have most all common ICs you'll need fairly cheap.

Oh, buy sockets, lots of sockets. Soldering ICs to the PCB might save you space but the second you screw up and blow one, you'll wish you never soldered all 14 pins in... (from experiance, twice waah).

Ive only got a relatively small amount of bits, and still found it useful to make an excel file.

Another thing i was thinking of, in line with your idea, was some sort of BOM tool/project tool, where you could import project BOMs and it could tell you what to buy, or which projects you can crack on with.

With the sheer number of parts, and ways of describing them tho im not sure if it could work...

great thread. i wish i had this info when i started 1&1/2 years ago, especially iopop's component descriptions. now i can add to my growing stockpile!

regarding cost, if ordering from the US i've narrowed it down to two suppliers, mouser and futurelec. mouser for caps, common ic's, sockets, large order of resistors (#200) and solder term pots. futurelec for trimmers, htf ic's, small number of resistors (#10), and pcb pots. the cost for trannies can go either way.

ebay is also an option for htf parts.

its been mentioned many times, but it takes a while to get the futurelec order due to slow boat from china.

I use a board layout SW called Altium Designer which has pretty extensive libraries and editable attributes. When I make a new circuit and PCB, i can export the BOM and it has all of the supplier links to the parts making ordering super easy. But a raw BOM import would be very hard... there's soo many parts of the same value/type.

mostly the same here...but ive recently fallen in love with digikey for small parts orders instead of mouser, mostly because i can get stuff shipped to me for less than $3 instead of $7-8 minimum shipping cost from mouser.

i get my solder term pots and partially bonded wire (same as blacet kits) from smallbearelec.com. the wire is really the best for soldering, makes life easy.
