Samsung UN55ES7500 with stand and remote. Not a scratch on it and absolutely nothing wrong with it. I seriously don't know what makes someone wake up one day and say to themselves "I just can't stand that gorgeous, big, smart, 3D 1080p, 240Hz any longer - I'm going to put it in the car and drive it down to the electronics recycling drop off". Owner of this thing has probably been divorced 3 or 4 times I'd guess.

I just wish they'd have brought the Bluetooth active 3D glasses too 'cause I don't have any of those. I only have the passive ones that came with the LG that I bought some years ago.

Default Re: Your Best Dumpster Finds

I got two mismatched Sony bookshelf speakers that were sitting in a box on a nearby street. I thought they were the same model, because they looked nearly identical, but they weren't. One is a SS-MC3AV and the other is a SS-MC1. Difference appears to be about 1" or so in the depth of the cabinets (the MC3AV is deeper) and also the woofers: both use 6" woofers, but the SS-MC3AV has a "quick edge" woofer, which is stiffer, uses polypropylene cone rather than paper, and looks more suited towards low-end notes.

That said, both speakers must have come from the same Sony MHC-MC1 or MHC-MC3AV "Mini Hi-Fi Component System", at least according to the manual. The MC3AV speakers are used for the front while the MC1 are used for the rear. So essentially, I got a front and a rear speaker. But they sound about the same, with the MC3AV only having a better bass response. Though, I should note that both have surprisingly good bass response - dare I say even better than my bigger Sony floor speakers that have 8" woofers. I think this is due to the fact that Sony did a decent job here with the design. Rather than making a big speaker with big woofer driven by a small magnet, looks like the woofers in these speakers have fairly large magnets for their size. On top of that, the voice-coil appears to be 1". While a 1" voicecoil is not so good news when it comes to power-handling, it does allow for greater magnetic field density in the motor's gap, thus allowing the speaker to drive the cone with more ease (which typically results in better bass response).

Now Sony does rate the MHC-MC1/MHC-MC3AV system as capable of 80 Watts RMS per channel. But I find that a little suspicious, to say the least. A 6" woofer driven at 80 Watts RMS is going to have some serious excursion/travel. And I think my suspicion is not unfounded, as the system is rated at those power levels with 10% THD, which is garbage. That said, they do also rate the system at 40 Watts RMS with 0.09 % THD. Now that sounds a bit more plausible... though I am still not convinced those speakers can take 40 Watts RMS. I think 20 Watts RMS on a good day is the best they will do before their 1" voice-coils burn out.

If I have time and patience some day, I will try to open one of these speakers and take pics of the woofers. Maybe they are better built than I think.

Today I grabbed a cheap 6-inch bench grinder from someone's trash (I did ask permission). It is broken, and can't really be repaired. It is only $39 or $49 for a brand new one, so I'll throw it out. I don't think parts are available for something this cheap.

That same person was also throwing away an HP S1931A, 19 inch "9 by 16" LCD monitor. It has both VGA and DVI inputs. I only tested the DVI input. Works fine, all pixels work, backlighting works. It has a green plug for "sound in from sound card" so it must have speakers, but I did not test them.

I don't really NEED this monitor, but my other spare units are either heavy tube monitors or "4 by 3" LCDs. I seldom get any "great dumpster finds" like most people here, but that's okay. That makes this find special.

Interesting to know what is wrong, though. Might also have useful parts inside (I doubt it, but you never know until you tear it apart).

You mean 5:4? (i.e. 1280x1024)

I'll take a 19" 5:4 any day over a wide screen 19". Or, if you really have 4:3 LCDs, those are even more valuable, as that is rare aspect ratio for LCD. The ones I know that have it are 21" with 1600x1200 (but also 15" and 17" with 1024x768 resolution ).

Think it's 20.1. Eizo has some dirty expensive 1:1 though.

The left side of the motor housing was broken in two (all 360 degrees around), as if the unit had been dropped. Maybe I could have removed the broken part and all the safety guards on the left side and used it (if the motor and bearings were okay). But that's not safe. It was a 6-inch bench grinder from Illinois Industrial Tools - isn't that a Harbor Freight brand? I already threw it out - I believe spare parts don't exist, and taking it apart does not appeal to me at all.

Right now, the best economic use of my time involves working 50 hours a week (for three-quarters of the calendar year, actually) and replacing worn-out front suspension components on my car. (I do have another car for my daily driving.)

And yes, I meant to say "5 by 4" LCDs (not "4 by 3" LCDs). Sorry about that.

Asus P8P67 Pro motherboard with a Pentium G630 and a bad #1 PCIe x16 slot (but the other PCIe x16 slots work, albeit at x8 since only the #1 slot is truly an x16 slot).

Found a Tesla Color Oravan 4333A TV two days ago, don't have much use for it but maybe some collector will be interested. The induction cooker which was put on the TV may be of better use, gonna have to check it…

^This, a few years ago when systems with DDR were still worth upgrading the prices were crazy for the 1GB sticks, but now that most systems with DDR are too old for much of anything (virtually no one is still using, much less paying to upgrade Pentium 4 and first gen Athlon 64 systems anymore) the prices have dropped to almost nothing (<$5 per stick).

It is simple supply and demand, after the major manufactures stop making a certain kind of ram but the systems it is used in are still relevant/worth upgrading the price goes up, then once the systems that use said ram become too obsolete/not worth upgrading the price drops again.

Than the chinese come and start making no-name sticks for few bucks. Memory prices have not been so low ever in the history as they are now. Anything but high-demand types (DDR3 8 or 16 GB, DDR4, DDR2 ECC 2 GB) costs almost nothing.

As for K8, if it is 939 you can easily get dual-core for few bucks and it can still be of some use, 99 % systems accept X2 CPUs, many even without BIOS update. Most Intel systems on the other hand are screwed unless it is one of few chipsets which support at least Pentium D, if not Core.
