content: I have access to a huge volume of surplus electronic components and electronics-related components (connectors, wire, cables, hardware, modules, etc.) I buy only what I can use, and what I know I can resell, and what a few people have told me they're looking for. But, that's only a fraction of a percent of the total component mountain, much of which eventually goes out to recyclers. (If you saw what goes out you'd weep, barf, and maybe worse.)I'm thinking it might be feasible for me to significantly expand my "want/wish-list" holding for others, especially for y'all here on EEVblog. (For example, I have a high voltage capacitor enthusiast, and a precision resistor enthusiast, so I try to work deals on whatever of those items are available.) So, what kinds of components, or specific components, and quantities might y'all be looking for? Maybe I can find them amongst the piles and gaylords and pallets.

content: I'm sure I would weep. So much gets recycled that could very well be used as-is, instead. *sigh*I'd love to help. The thing is that I'm not sure how. My needs are modest and varied. I could go for a nice stock of jellybean goodies. But most of the time what I need depends on the equipment I'm fixing. A lot of the time, it's electrolytic capacitors, but they vary widely from one device to the next.So, I'm up for helping reduce the unnecessary recycling.Edit: Any nice aluminum enclosures and/or knobs?

content: Enclosures aren't an everyday item, but occasionally some knobs show up. I rescued a case of nice Kilo knobs a few months ago.Electrolytic caps typically come in cases of OEM bulk bags (100, 250, etc) or on (often partial) tape-n-reel. I can get them by the bag or case or reel. SMT electrolytics typically come on (often partial) reels or in trays.These days most of the stuff is RoHS, but some isn't. Some of the stuff is relatively fresh, but some isn't. And etcetera. So far I haven't had any hand-solderability issues, either conventional or hot air. Visually it looks fine and typically was properly stored, then liquidated when its manufacturer-defined shelf life expired.I love to find ways to get this stuff into the hands of people who could use it.

content: I'm always on the lookout for interesting display modules (OLED, VFD, EL). If you come across any (and feel like shipping to AUS), let me know! When you say "modules", what are some examples?

content: I know I could use some small qtys of caps, small assortments if you like, would love some leds esp smaller power ones.

content: Well, since you asked...I'm just getting back into electronics after a long absence.I'd be interested in easy to repurpose/reuse modules. My current projects are embedded systems and small wheeled/tracked robots. Cheap, interesting modules to tear apart and salvage would be good too.Right now, I could also use grab bags of common jellybean components. I'd prefer new, but trimmed leads would work too, as long as I can get them into the breadboard.Resistors, 1/4 or 1/2 watt, 330, 470, 1k, 2k2, 3k3, 4k7, 10k, 100k, 1M, 10M. Precision would be awesome.High-wattage, low value resistors. Whatever you could find. Low inductance would be preferable.Caps: .1 and .01 disc (bypass), 1, 4u7, 10 and 100 uF. Quality, known brands, 35-50 volts.LED-- various colors, but prefer consistent sizes--e.g., size matched between colors. Red, yellow, green, white, blue, aqua, and IR. One or two UV, I wouldn't need too many of them.Voltage regulators--positive and negative 3V3, 5, 12, 15, and adjustable.Displays-- seven segment, alphanumeric, LCD, and VFD. I'd need datasheets or hookup information for the LCD and VFD. If you could get them, serial or I2C interfaces would be even better.Buttons, keypads, and pots with caps---good quality, common sizes/values.Small motors and steppers. 3-12 volts.In the future, small graphic LCD panels with controller & driver boards.A couple of analog meter movements.Almost forgot, old-school transformers. I'd love some 2 to 5 amp output, center tapped, 7 to 35 volts.Do you come across any small hand tools, soldering, or test equipment?Trying to get into SMD, but can't go too small yet. Maybe 1206 size components listed above?Last, but not least, reasonable shipping to 20032.

content: Painful to even think about.Hmm... my want list is here:http://everist.org/spacejunk/want/Parts_I_need.htmIt needs updating. That first item (the CDROM drive interposer) I no longer need.Tri-ax cable and connectors, yes.High voltage BNC connectors, both genders and panel mount? (They have longer bodies than the standard ones.)Shrouded and unshrouded banana plugs?High flexibility test lead wire?When you say 'modules' do you mean like metal blocks with connectors, or plugin modules for scopes and such?I have a HP 83480A digital communications Analyzer - scope, that I hoped to find some plugins for, but they turn out to be always beyond my price range. Due to still working in current model Agilent scopes. Oops.For eg want: 83481A, 83482A, 83485A. And the HP 54750K firmware upgrade. I expect this is not the kind of stuff you have.Do you ever see any vacuum systems gear? Plumbing, couplings, pneumatic valves, vacuum gauges, etc.Components - hard to say. I never know what I'll need till I'm building something. But, I have a US reshipper account so it's feasible to ship large heavy boxes. If some kind of bulk lucky-dip mix could be possible?Can you post some pics of the kind of stuff-piles that pass through?Also, _why_ is it destroyed, rather than sold off very cheaply?

content: Hello people,Dwayne here from the Riverland in South Australia. After a 30+ year absence from electronics I am looking to get back into it again. I'm in and out of rehab with severe depression and I've been told to take up a hobby of sorts and Dave's videos (I'm half way through his list) has got me all interested again. I'm leaning to the Aurdrino & possibly Audio side of things (I used to be a DJ). I'm currently saving up for a Oscilloscope, soldering iron & function generator.Then I saw this thread. I don't normally like asking, but I could do with as mmany resistors, capacitors and transistors that could be thrown at me.I "may" even be able to help with postage.Thanks in advanceDwayne J MaddenP.S. I did see Dave's video on the free Oscilloscope give away but alas, I'm only new to the forums so i'm out of that picture

content: I would be interested in TCXO and OCXOs and VFDs. And maybe some SMD LEDs and SMD ICs that are mostly used (OP amps etc.). But everything comes down to the price and price of shipping to Slovenia.

content: I have been away from electronics since the early 70s. Now retired, I am trying to get back to it. For now, I am starting with through hole parts. The retailer's 100-pc price for TO-18 GP transistors (NPN 2N2221/2222...) places them way out of my league as jellybeans (can only afford dark plastic ones). So it would be awesome if some bags of those shiny parts and their siblings (PNP 2N29056/2607...) showed up in one of the piles, begging you to take them away from the crushing jaws of death.I do have some small drawers where to place bags of quality ceramic capacitors (0.01uF...).May be some 2N7000s, CMOS '4049/50s, darlington ULN2003s, 74HC166 shift registers, 74HC4051 analog switches...What about op amps? Do they ever get discarded ? (lm324, op07, lm358, ua741, TL071, NE5532, DUAL: lm2904, lm358, lm2903, TL084, MCP6002, MCP6294... )I am missing anything... ? Yes, what about- small relays, 3.3V5V/12V, SPDT/DPDT- trim pots, multi turn pots- OXCOs- precision resistors- common values electroliticsIt is all a matter of availability and cost (other than shipping). I appreciate your effort to find decent homes for all that stuff.Back2Volts (Tony)

content: Precision resistorsAny triaxial related stuff? I have ONE instrument that uses triax and it would be nice ot get some cheap triax-bnc adapaters and/or triaxial cables.
