All my dumpsters are full of month old McDonald's and Hobos. Your dumpsters are full of salvagable equipment that I can't even afford in the condition it's in. Fly to me to your dumpster, oh trash lord.
Yeah, I would try to get that whole container with me, so much nice stuff and what is not possible or too expensive to repair still contains many nice parts that are hard to find or too expensive for most, like those two transformers or even the rack cases.
I feel you, I would repair and repurpose the whole lot! It's fun because it adds a lot of creativity to the technicality of repairing, designing and building electronics. And it helps waste recycling too~ I already scour second-hand websites and stores for stuff that people want to throw away, but man a dumpster like this is not something I can ever imagine happening here...
Historically this said company would list their old stuff on ebay for ages before putting in the bin. Never sold well. Not worth the effort of their own staff reconditioning this stuff for sale. I

@@Okurka. I did not actually reviewed the video. I am just assuming that there are components missing which is the reason for the cut wires Dave is pointing out.
If I ever found or was told about something like this I would need either a massive uhall or a dump truck sixzed truck to talk it all home. I love messing around with old school equipment
I'm catching up on your videos after not watching much on UA-cam for a year or so, and this is the most exciting one for me so far! Dumpster diving is probably my favorite thing to do involving electronics, and electronic stuff is my favorite stuff to dumpster dive for.
Who ever put the equipment into the dumpster first deserves a huge "atta boy" as well as the earlier dumpster divers for not destroying what they left behind. There was obvious some love and respect for this old equipment!
It is really a shame people throw it away like this. I have seen people throwing literally good things in such container to be sure that it will ended broken. Usually happen after bankruptcies when the building needs to be emptied quickly. I do not understand the behavior, it makes me feel sad. Nice equipment, good catch Dave!
Once I had a 500VA torroid bolted in a metal case. The lid touched the top of the mounting bolt. OH BOY did the top of the case get hot where it touched!!!
Now that brings back memories. That equipment is from a Telco site. I use to install those 48v rectifiers (Battery Chargers) in the Exchanges/Radiocom sites way back in the 90's. They are 50A with load sharing to other rectifiers. They use a daisy chain ribbon cable on the front panel for Coms between the rectifiers. Very reliable & they use passive cooling.
I make regular checks at the Electra recycle bin at my local supermarket. Always good stuff. Nothing like here but even new PSU's, drills, routers, motors, USB cables etc. Most of it in working order, some even new in the box
One quick note - the "48V rectifier" you mentioned is likely a part of a DC power plant. These plants would take mains power in and provide clean DC power (48V) out for equipment that uses DC power supplies (in an ISP perspective, routers, switches, etc) - DC plants can be configured to provide hundreds of amps of DC power using multiple rectifiers. These plants also have batteries to provide hold-over power in the event of mains failure - long enough for a generator to start.
Rack mount UPSs use 48v battery backs, and I've also seen large 48-port network switches that have DC inputs. Perhaps it's more efficient to just have a horkin' big 48v DC power supply (with voltage levelling at the individual devices) to power all your racks than to have every device on the racks with their own power supplies?
Yup - I work for an ISP and all of our equipment locations use DC plants to provide 48V DC power for our switches and routers. The plus, I guess is clean DC power to the equipment, the sucky part - the DC power supplies on the switches/routers don't have easy to disconnect power cables (screw lugs). Additionally - in our locations, we have dual DC plants so the equipment has redundant power. (The larger routers actually have 4 or more power supplies - e.g., Cisco 9910 - 4 x 4.4KV 48V DC power supplies, minimum) :)
Why do these large routers need so much power (4.4 kW)? Do they have powerful computers inside, provide PoE for additional networking gear, have optical interfaces with powerful lasers?
Well - the Cisco 9910 I mentioned is a pretty hefty beast. Fits standard 19" rack, but is almost 3ft tall, and fully loaded with Route Processors (2) and line cards (8) weighs in at around 400lbs. And - eash RP is a powerful multi-core processor + lots of custom chips for routing, the line cards also have powerful CPUs + custom chips for the fiber interfaces (16 x 10Gb or 8x100Gb typical per line card) + on the 99xx routers, add in "fabric" cards which control the backplane and manage traffic flow between RPs & linecards. Throughput for the router is in the multi-Tb/s range... they really move data! (and sound like a jet engine when running). - and - the 9910 isn't Cisco's largest - they're just the ones I've played with.
I suggest an helmet with a magnet where you can put the camera to have free hands. It gives us a better overview of the dumpster, and makes you look more nerd! :D
A lot of places do that, it gets sent to a sorting center, to get sorted out by workers, and what does not get recycled, and is organic waste is sent to what's known as a trommel, where it's turned into energy. The whole process is known as single stream recycle, and the thought behind it is if it's easier for the end user by not having to sort everything out, then they are more likely to recycle.
48VDC rectifier is from telecom equipment PSU. Almost every radio relay station, GSM (HDSPA, LTE and all others), PMR, PABX and everything around it use 48VDC for power. The point - it's efficient and compact to convert 220 / 110 VAC to 48VDC, and you can put 4 Pb acid batteries and get a 48 VDC. Most of power supplies for telecom can use backup batteries - charge and get power. And those rectifiers are modular and hotswappable. Modern rectifiers can pull through 1200 watts in a 1/8th of a standard 19" rack unit size.
Oooooohhh... an RF Millivoltmeter up to 1.5GHz !!! I work in a cal lab that specializes in avionics test equipment, would love to have something like that for DME and Transponder stuff in the L-band. We have a high impedance probe for our HP spectrum analyzers though... but I'm a sucker for the simplicity of the old gear like that! Verrry interesting note about the toroid transformer!!! It took a second to realize what you were talking about :-)
My LeCroy 9410 sat in a storeroom at Hughes Aircraft in California for over twenty years, and from what I could gather was probably only used for a year or two. It was in near perfect working order, only needing a DAC gain adjustment. I would like to be able to find a GAL for it to unlock some of the premium features.
I would quite like to see you dismantle that 40A battery charger thing and figure out what’s wrong with it, and also measure the capacity and estimate whether the battery is screwed and talk about internal resistance
Can you consider tearing down one of the microdrives you received in a mailbag years ago? Actually, can you consider tearing down everything you received in mailbags over the years and are now collecting dust in your storage unit? Some of it is extremely interesting. thank you -watcher since day 1
Hi Dave, Very interesting teardown. I love your channel and interesting contents. I think I'm familiar on the road you're driving and I can see where you end up. The first traffic light is the Park Rd corner Station Rd. The second traffic light is Powers Rd cor Station Rd Seven Hills. After the CALTEX on the left is the RFI building logo and you end up the driving behind the big truck which is roughly 87 station rd. I can also see the reflection from your right eyeglass the logo of the company "C" which is the globe sign. If I'm not wrong, this dumpster must be EMCTech at Seven Hills. Cheers
Got it, thanks. I'll look into what's in my area that could be promising. I sure hope we're going to get a look inside some of this stuff, or maybe a repair video :)
Recycling 10/10 it looks like it's in a Common dumpster that goes to the landfill..?! edit, there is even florescent light bulbs and a xenon (read, led) light bulbs APPALLING and What cost? That should be straight illegal. Shame on you Australia. And EEVDave at least you recycle.. Keep up the good work! :)
Same problem. The only things I can get occasionally are typical household stuff. (Not from a dumpster btw. My father rents a bit of space to some people and they throw their stuff to our old metal collection.)
My former employer has rooms full of equipment like this. I used to keep the Tek 475 on my desk for fun and good conversations when people would wander by.
Wow...glad to see you Aussies are concerned with heavy metals. Those old chart recorders have mercury in them...yea...Hazmat! We had 2 of those old chart recorders, and we had to call in a company to take them off our hands because of the mercury in them.
Tell me where!! Somewhere near Seven Hills I take it, out where every industrial building looks the same. I don't need a mains interference simulator, this apartment chews light bulbs within 6months. It has been raining lately anyway.
Tear down the HP 8620C! That thing has beautiful internals. Take a look at the construction for the front panel. You can flip a lever and the whole front panel hinges down for servicing.
I guess no, but that doesn't seem like a common dumpster, more like a construction one. I assume they will sort the waste when they remove the dumpster.
looking very much like this company was into broadcasting equipment maintenance. The 48v switchtech power supply is quite common in that field (though that model is being phased out) Note that when hooked up to batteries it will run a positive earth.

Wow, so much gear that could be rescued! And here I am struggling to find suitable items to BUY to make repair videos on!
So much waste, when it could be serviced and resold
Yeah, I would try to get that whole container with me, so much nice stuff and what is not possible or too expensive to repair still contains many nice parts that are hard to find or too expensive for most, like those two transformers or even the rack cases.

The dumpster i go to has smart tvs washing machines etc enough to furnish a house
When I was a kid, I would literally dream about stuff like this.
Just look at the fonts, layout and colours.
Some of the old gear had a lot of thought put into design and style that you don't see today.
Look at the new Rigol 7000 series front panel! (Trigger Warning)

I want to live in that dumpster
I don't see anything worth keeping.
Be careful what you wish for!
haha well said
Dave, you are driving on the wrong side of the road!
Everyone is driving on the wrong side of the road, so everything is fine.
yes, and his car came broken from factory - it has the steering wheel on the right side... :) - btw, had to live for a very short period in UK, I didn't dare to drive so I discovered that's a sweet life to have your own driver
And so fast too!
The correct side of the road!
U should come were i live you drive in the middle the roads are so small lol
Hint: Maybe the plate with the two coils was the top plate and the cut wires in the 500v PSU were going to the top plate.
@@Okurka. I did not actually reviewed the video. I am just assuming that there are components missing which is the reason for the cut wires Dave is pointing out.
Mixed dumpsters with electronics in them? In 2018? What's stopping people from recycling?
why are dumpsters a thing even
cost
krattah im sure they could of even given these to schools for free, even though these things are old they’re still better than NOTHING.
A dumpster like this would most likely be sorted and recycled.
Yeah i really was missing a Siemens 200Hz-18Mhz Level Oscillator in school...or some old af Sweep gen...
wait no, i didnt.
Lol... the HP unit with both "calibration not required" and "do not use until calibrated" stickers.
F the calibration. Just use it anyway.
If I ever found or was told about something like this I would need either a massive uhall or a dump truck sixzed truck to talk it all home. I love messing around with old school equipment
Like a candy store for adults... I like it!
With all this equipment you are picking up there is going to need to be a Throwaway Thursday next to clear space for the next dumpster load.
Did anybody feel disappointed Dave didn't plug it in.
You know the mantra. Don't turn it on, take it apart!
It was already taken apart though.
there something missing on the back, wires are cut
Yeah.. said DC fuse on the back. Have to tie those wires together if you wanted to use it, I'd guess.
BlackEpyon judging from missing fuses, plugging it in couldn’t have turned it on, and perhaps even torn it apart.
Whoa i woulda grabbed those toroidals for sure! Awesome pile of crap !! I used to love dumpster diving back in the day
Yes i wouldve taken them definitely. They looked like pretty powerful ones.
Being toroidial, winding additional secondaries is easy too.
those are not cheap...seemed like pretty big beefy ones too!
Don't worry-somebody probably came along after Dave and picked them up.
I'm catching up on your videos after not watching much on UA-cam for a year or so, and this is the most exciting one for me so far! Dumpster diving is probably my favorite thing to do involving electronics, and electronic stuff is my favorite stuff to dumpster dive for.
Nice! Haven't seen a real time dumpster five in a while. Can't wait to see what works and what needs fixing.
Brilliant! A Switchtec rectifier! I worked on those rectifiers in the late 90s. They are pretty solid from memory.
Ah, the Tektronics 475. That's the scope I learned electronics with. Heart-achingly familiar after all these years.
I *LOVE* Dave's teardown videos. Always brings a 'tear' to my eye. *sniff*
Woohoo! Looking forward to seeing inside of all this gear!
Who ever put the equipment into the dumpster first deserves a huge "atta boy" as well as the earlier dumpster divers for not destroying what they left behind. There was obvious some love and respect for this old equipment!
So many components if nothing else.

But the light tubes in the dumpster were all already crushed and the Mercury evaporated into the environment.

Electronic waste is such a huge problem. Shipping it to China is not a solution.
What waste (apart from the printer, potentially, and the totally-obsolete chart recorder)?
Schaffner equipment is often used for RF and EMC applications, even old units can be of interesting value these days.
Yeah Dave. Used VU meters on Ebay are expensive..
Hey, any equipment you pick up free is great! Happy teardowns!

Still can't believe that people throw out this stuff !
Wish I could find a skip full of stuff like that! I noticed STC and Telecom badges on some of the equipment. Quite interesting!
What kind of buildings would have stuff like this in their dumpster? Seriously, where should I be looking? This is absolutely glorious.
It's a very specific company that needs this sort of stuff.
Got it, thanks. I'll look into what's in my area that could be promising. I sure hope we're going to get a look inside some of this stuff, or maybe a repair video :)
Could be any company that does their own EM/compliance testing, some of it's clearly for that. The rest of the gear is too odd ball to narrow it down.
Surely there would be a museum that would appreciate this
ALL of that is FIXABLE !
Painful to watch, but I'm glad that you saved some of them.
Specialist stuff mostly, no great use for the average user.
The scope and voltmeter look usable.
Several signal generators covering kHz--GHz is ``specialist''?
Yesss! I love Dumpster Diving! When I see one I have to take everything, even if I ran out of space. xD

Are they legally allowed to throw these in a dumpster in Australia? I figured those old electronics would be full of lead.
We're supposed to use e-recyclers which it suposed to stop it going to land fill but I'm not always convinced...
I guess no, but that doesn't seem like a common dumpster, more like a construction one. I assume they will sort the waste when they remove the dumpster.
