On a whim I ordered a few things from goldmine-elec.com, including a few specific parts for projects I am already working on. Aside from those, I got one Mini Free Surprise Box Gift, three Electronic Surprise Box, and two Super Electronic Surprise Box. The reason behind this is my dreadful lack of miscellaneous parts to play with on a whim.

First of all, I have definitely solved that problem. I will catalog here the contents of the boxes, to better inform other community members considering such purchases. Virtually every component, with a few noted exceptions, is leaded, not SMT, and about 10% of the components have leads bent out of their useful positions (but not broken or unusable). Of the components still on tapes about 75% are well kept while 25% have one leg detached from the tape or bent leads. I kept pretty accurate counts of most things, but the ones above about 50x are estimated.

The mini surprise box is a freebie on any purchase of $25 or more. It came in a cardboard sleeve, about 12 cubic inches of stuff.
6x TOB50K sliding potentiometers
5x 10K single turn potentiometers
2x 1K single turn potentiometers
1x 50K large single turn potentiometer
3x TO220 22N50/185

50x 2mm x 3mm blue toroids
2x volume knobs with tightening screws
2x holiday noisemakers, single PCB with speaker, battery, pushbutton.

I don't want to rain on the parade, but you'll find that there is always, really always, in any DIY project at least one part you don't have in stock. You can buy as many surprise boxes or sets as you want, one part will always be missing when you do a project.

On a positive note, it seems your surprise boxes contain useful parts. I have seen other "sets" that where practically just a way for the vendor of getting rid of electronic waste and being paid for the waste.

On the first day of Christmas...Laughing

Lord, how this stuff accumulates. In a few years you'll be paying someone to get rid of stuff like this.

Tip: put the stuff into small plastic pouches and label them. Sifting through a hap of junk looking for something in particular is not my idea of fun.

ArnoldB, the issue of worthless surprise boxes is why I am doing this. I want other people to be well informed when making purchase decisions. I think that these boxes are well worth the cost. In each box I have opened just a couple of items, at quantity, have more than made up the value of the box.

emuler, I am rather precise when it comes to sorting and labeling, thanks for the tip. I know that there is a good chance I will never use the majority of this stuff, but the choices it gives me are well worth the trouble of sorting the ones I don't need to find the ones that I do.

PS: unopened boxes notwithstanding, I will never have to shop for 3.5mm phono stereo jacks again Smile

The next time you play Electronic Goldmine, check out "EVQ" Panasonic EVQ-WTEF2515B Mechanical Rotary Encoder

Endless quadrature "encoder" with shaft like would be on a 'scope knob. Obsolete model, but DigiKey lists similar for about $6/each; about $1+ as "surplus".

They are in great condition, I could almost certainly sell them on ebay. At even 5 cents apiece (10% of qty100 price on mouser) the 300+ of them that I already have (without having tallied half the boxes) would recoup what I spent on the boxes.

Interesting, that is a lot of typing...?

Do you have an economic interest in sharing the contents? I have so much to do in a day that I certainly could not afford to waste my time detailing the contents of a surprise box.

No offense...just seems like lots of work for no reason. I have a local surplus electronics supplier that sells all of those items. I have accumulated so much stuff that I will never use...

Altruistic interest. As mentioned above, some companies' similar boxes are less helpfully varied, some could even be called rip-offs. Now when someone is interested in buying this sort of box and searches these forums they will find a few examples from this company. When I order a similar box from another site (which I will be doing from at least two other sites in the near future) I will make a single post for each of them as well.

I know that I, personally, would be grateful if this information was already published by someone else, and thus I publish it for others to reference. I have no economic interest or investment in your purchasing decisions.

PS: Making the list also provided a small personal incentive to bother trying to identify more of the parts I did not recognize, which otherwise would have ended up in my mystery part pile.

Ah junk boxes...yes I had great fun...I remember many years ago (25?) buying a 10 lb surprise box of resistors from Olsen Electronics (still around?) Well, I spent many hours sorting them into 10 bins by color code.

After finishing, I wished I had sorted by the multiplier band rather than the 1st band! I still have 'em this way & still occasionally dig around for one...probably still have 9.5 lb left....some day I'm going to hook them all in series.

Around the same era, we came across a whole LARGE dumpster full of BRAND NEW, in the boxes green bar printer paper (?!!?)..Thinking someone had lost their mind, we of course loaded up our car with all we could haul & went into the "paper" selling business door to door at various companies...After spending our first money, we got irate calls, that the paper would not fit in any printers since the two sprocket hole sets were not punched in synch from side to side. So much for our empire.

I have parts that I bought as part of those "Grag-Bags " way back in the mid-1970's, that I've still not used, and never will. For me, they are a waste of money.

Even as well stocked as my parts bins are, I'm still needing some part or another to complete a project - that's just the way it seems to work out.

Worst case, I throw 90% of the parts away (the likely fate of the remaining mystery parts), and the remaining 10% were still well worth my investment. The headphone jacks, pushbuttons, and SPST/SPDT/DPDT switches more than make up the value of the boxes, and I expect to use all of those eventually.

I suffer from the disease called "Can't throw usable stuff away". Like the previous toaster, CD player, several old PCs.

Need to find a 12 step program.

A quick update... did this again with some friends, documented in photos and a short parts list.
