Which inexpensive and useful technology items did you order from Aliexpress, eBay, DX, Banggood, Tinydeal etc. recently?
I can't even remember the last time I bought something actually useful from those chinese shops.
My $7 arduino clone shorted out
my $5 mechanical skeleton watch broke
my $3 safety razor rusted itself through the nickel coating
usb sd card reader couldn't maintain a USB connection for longer than 10 seconds at a time
i could go on
This DIY oscilloscope, only 200khz bandwidth but it's ok.
My uncle who lives in china to do black people fraud things but with the untapped power of cheap chinese goods brought me back a "Lioncharger" portable USB battery thing
I've used it maybe once
WHERE CAN I GET A CHEAP OBD2 READER? WILL THEY WORK ON FORDS DESPITE BEING MADE IN CHINA?
please respond (my truck's dead)
I have been trying to make money fixing up and selling broken vg consoles.
Lately I've bought Nintendo-sized safety bits (I misplaced the nice ones I had), A PSP replacement shell kit, cheap 3rd party SNES controllers (for the boards), and AV/Power cables for several systems (most things are missing cables when I get them).
If anyone is wondering, I'm technically making money, but it works out to way less than minimum wage.
Like I said, limping along.
In hindsight, it seems obvious, but there's a lot of competition and the collectability value of retro stuff makes the margins really slim.
A broken SNES/SFC that needs 8 hours work to restore is only worth $10-$20 more than an equivalent condition unit that works and has all the official accessories.
If you have an Android phone you can use it with the 'Torque' app. You can also find them with a USB cable, just look for ELM327 adapters.
used it to shutdown others tv

I bought a usb cable to charge my n3ds on the go/on my desk. It smells a bit weird though, but not as bad as the otg adapter that I just threw away the second I got it. The 3ds cable seems pretty sturdy and nice for a chink usb cable.
I hope the smell goes away if I put it near a radiator for a few days. I sorta don't like touching the thing if it smells.
Probably not much worse than fresh neoprene though. That shit actually smells breddy gud even though it is full of cancer
3200LM motorcycle headlight LED $9.80
heatsink tape $cents per sheet
3700mAh 18650 $1.08
RTL8188EU WIFI adaptor $2.04 (works far better than built-in wifi BTW)
All inclusive of postage. Post stuffs these things into my letterbox trying to break them and I don't even care, because the alternative is to buy them at 4x the price and fund local business mafia
Why are these chink packages so slow? I mean, I'm not complaining since it's free but I'm just wondering: shit takes more than 2 months to reach me, anyone else have these abysmal shipping times?
i picked up a tx/rx, osd, and video monitor for adding a video feed to my drone. ends up being like $70 for everything for what will basically be the proof of concept for building upon, pretty damn cheap
bought chink audio connectors... took half a month but was cheap
thinking about making audio cable
Thanks for the info just fixed up my old HD5970 (same fan) to use in my sisters pc but the fan should be replaced but those fans a too much (18$) so she just have to live with it.
Have a 2 year old VAG-com from China still works but is gonna get a new one with a updated firmware to use it with the new version of the software.
Planning on getting a cheap tablet to strip it out of its case to put it into my car as a mediacenter (properly gonna be shit)

have you recieved it yet? does it work well? I heard some of the absolute cheapest ones waste a lot of power and get real hot.
Neither my x200 or x220 have usb 3.0 built in so I'm in the market for one of those.
I bought in the last few months: some posters, usb cables, usb connectors (various, for diy purposes), a usb 3.0 to sata bridge (for 2.5" hdds), a usb 3.0 enclosure (for 2.5" hdds), a usb 3.0 enclosure (for dvd/bluray drives), a 2.5" sata to 1.8" sata enclosure, some posters, some tree elves, some velcro cable ties, a mars rover model (my favorite, pic related), some xbox controller parts, a glass screen protector and back cover for my lumia 640, a handfull of flashlights, a zif ide -> cf adapter, a cf -> sd adapter, a 2x2.5" to 2.5" adapter for hdds, and some green tea kit kats (not china)
pls help I keep buying all this stupid shit
though I have only spent like $60
I think it has to do with when the packages are shipped and how long they take to go through customs. Some sellers ship the same day and it actually leaves, other sellers may say they shipped it and it just sits around for a couple weeks before it actually gets underway.
The posters I ordered only took like a week, but the electical parts took like five weeks.
Isn't the real bandwidth of those like 20khz, pretty cool toy to have but if you want to any real measurements better off with and old analog scope or if you have the dosh a new digital one.
Yeah, you're right about the shipping. Probably also has to do with which province it comes out of. If it's from a major city or industrial area it's going to get processed quicker than from a smaller area and has to be at less intermediate points.
I want those tree elves now. Your buying useless shit disease is contagious
I bought one of those really cheap ones from china before I got this one and couldn't even get it to work. But I got this startech one a couple days ago and it works really well and keeps cool.
>Your buying useless shit disease is contagious
I can't help it! I work nights and sometimes I get bored with how quiet it is. You can only brows 4chan so long before you get bored and see how much shit you can buy that you didn't know you needed. On the bright side though, a lot of the stuff that I bought I would have purchased anyway since nearly all of the electronic crap I bought was to repair or replace old hardware.
I also bought one of these to hide in my moms apartment. She loves groot and has been wanting to make one.
plz send help
Cree q5 flashlight-really well built and bright for $4
Jinhao 599- good fountain pen for $1.29.
Redcircle 600- decent rotring clone for $8
Orange pi- I could not get it to boot, so I just gave up after a bit. Should probably try again soon.
Trackpoint sample pack- ended up being official IBM/Lenovo, so they ended up being good
Android robot shaped USB OTG adapter-alright for $0.25. Part of the USB type c connector broke, but it still works.
10 piece Trackpoint caps- no where near as good as the legit ones. Rubber feels too soft, and some aren't cast properly. Buy real ones if you can.
Cool. What kind of laptop do you use it with? OS?
I'm a freetard, don't know if I need to be on the watch for drivers/compatibility and whatnot or if I can expect it to work right out of the box.
I bought cheap trackpoint caps off ebay - soft mushy garbage.
I then bought some trackpoints on ebay that were marked as "OEM LENOVO blah blah blah", US seller - marginally better cheap garbage.
I think I'm just going to have to order direct from Lelnovo, but I don't think they take paypal. Will probably get a prepaid credit card as I don't really trust them not to get breached.
sometimes it gets too uneventful so I buy random things I don't need so I can look forward to them arriving. to be fair, most are additional computer hardware or gook versions of electronic components that are much cheaper
Still waiting on some jumper cables for an SOIC chip flash
The fucker in the picture is at least 20USD when the gook version was only 5 $tacos
This bullshit thing is like at least $20
Chink version is significantly cheaper and doesn't leave my hard drives flopping around in the case.
44-Pin IDE Female to 22 Pin Male SATA Adapter
my external hdd died. would like to get a few files. nothing important or replaceable, but still would like to have them.
You can set the time base to 500s max and it has 12 divisions on the display and you can scroll further sideways (you see that green thing on the top middle? It can scroll about times the area you see on the display, so it would be 4x12divisions x 500s/division=6,6h)
So it should be capable of capturing a signal that changes over some hours. But you can't save it afaik (it has a USB port, but I don't know if it's only for updates or can also send logged data over there)
It's on a Toshiba Satellite with 32 bit Vista.
It comes with a driver installation CD. But it seems like they put every driver for every piece hardware they make on the disc and Windows couldn't find the right driver to install so I had to dig through it all just to find the proper driver. There wasn't a separate exe setup file for each OS, so I'd assume if you have an Expresscard slot it'll be compatible.
Forgot to mention some stuff
Xiaomi Piston 2: Pretty good. Too bad they're discontinued
Xiaomi in ear monitors: Newest xiaomi in ear headphones. Don't know how good they are, bought them as a gift for a friend
Xbox 360 wireless controller pc adapter: Does the job. Cheaper than the real deal too.
Can we add gearbest because i got a funduino and breadboard and sensors from there, and from ali i got 60 replacement sets og blades (240 blades) for my quad from the manufacturer for $5
Is this technology? Got this whoopee cushion for $1 including shipping from China.
Hey guys, which Willem Programmer will let me program eprom chips for my NES games? Everytime I go on ebay and aliexpress, there are always a shit ton of them that look completely different.
Something like the Logitech K400?
There are some offbrand ones you can get from Chinese sellers too. Be careful because of the different keyboard layouts and the support of bluetooth (some have USB dongle, the ones with bluetooth can be used easily with you Android devices e.g.)
hmm you can make budget tazers with these
USB powered LED lights I added to my last DealExtreme order. Haven't really put them to much use yet. The bare sticks put out a white light; I'm using the one on the right to light this photo.
The Xiaomi one in the middle puts out a soft white (yellowish).
Sometimes you have to jiggle them around a bit before they come on. I don't remember the price, I paid, probably not more than $3 for any one of them.
I got the pricier clip for liberating my x200.
I would have gotten the pomona if it was around 10USD. I think the cheapest I found was ~25USD at the time and I really am not in the mood to pay that much for a piece of plastic.
I will report back on how the Chink equivalent works once I finish with it.
Yeah, I did not see that there was a cheaper one, I just got the one recommended by the guide. I probably wouldn't have wanted to wait for shipping anyways. Have fun securing your freedom.
I have one of the cheaper, vaguely xbox controller shaped ones. It works well except that it is very difficult to read the keys in a dark home theater setting.
I recommend you spend the extra $10 or so to get a backlit one like I linked, same manufacturer.
LED light bulbs have to convert the 110-240V AC input voltage to a constant DC voltage and maintain constant current. So there is some kind of electrical circuit in them, and the cheap Chinese ones probably use shitty capacitors etc.
Another issue is cooling the LEDs. The metal part of the bulb, which is usually the heatsink, must be properly isolated from the mains voltage and of course the LED must not overheat, otherwise some parts may melt and cause a short and also a fire.
Going to try to build an audio-controlled ambient monitor backlight for my desk (the ping pong balls will be diffusers)
The UARTs are for a Leapfrog DIDJ that I bought that I'm going to try to get linux on.
Any of you ever bought seeds from china before?
If you're looking forward to the project, sounds fun. If you just want it to *work* you can already buy "music sound led strip" for ~$20 that include a microphone in the Led controller
was expecting >dude weed dude seeds to be honest. I've tried raising carnivorous plants before and it's really hard to find a balance of enough light without drying them out. Might work if you give em a a dedicated terrarium + heat&grow lamp for them. I always buy them with the intention of using them as countertop fruit fly eaters but they usually die in a month or so
I'm not mad because it's overpriced, I'm mad because it's all hipster reddit shit on mobile-friendly, UNENCRYPTED http connection.
1000 PERCENT MAD
If i'm going to be broke, I'd like to have not just given all my money away to hucksters who offered me shiny garbage that tickled my underdeveloped funnybone
>that's so clever and funny! it's a grenade made of chocolate, and it has M&M™s inside! I'm totally going to spend $9.99 + S&H on that!
>oh my god! It's lipbalm, but it says UNICORN POOP on it!!! xD that's so funny! And it's only $14.68!!!
I don't think they actually sell stuff through that site, so the http can be forgiven.
on the other hand it was a good reminder that I didn't have HTTPS everywhere set up on this machine yet
when I turn on strict HTTPS everywhere, the site just brings up a blank page
10/10 thanks for looking out for me, EFF
usb to ttl adapter
it was crap, gave no signal or shitty signal, maybe it was driver or linux problem
ended using arduino as usb to ttl adapter
You say all that like you DON'T need a pizza pouch
I use one of those in my car but the thing powers down after about a minute with no connection. I got pic related to make it less annoying.
The slightly more expensive adapters would likely sound and work better, but this still ended up cheaper than buying one of those.
Air mail: surprisingly quick, like 3-7 days. I live on the west coast of the US in a heavily populated area though.
Boat mail: two weeks if i'm lucky, median about 3 weeks, and the occasional package that hits the bottom end of the ebay shipping estimate of like 8 weeks
$6 fan controller
$1 Bluetooth dongle
$.8 VGA to Ethernet adapter because my college uses those for some fucking reason
$1 Tempered glass for my phone
And probably a new HDMI because I need an extra one
yes and on aliexpress there are many sellers that will custom print in an image that you provide (if they don't already have a suitable.
Say what you will about my taste, but I got this and I am very impressed. They say they'll do custom work too.
I've bought a TON of stuff from aliexpress and while I agree that the producs sold there are usually total shit, you can find terrific stuff there if you know what you're doing
I've bought 3 different SSD's from 3 different sellers, all working flawlessly
I bought a native 720p DLP projector, aside from some annoying and unsettling rattle in the fan at startup, it is pristine for the money I spent on it, it was around 180-200 $ compared to the 1200$ minimum I would need to fork up in Iceland for a decent projector
I bought 2 wireless keyboard/mouse packs, they're fine
I got a Teclast x98, and I love it, but I dont think this falls under the "inexpensive" category, although the teclast was relatively cheap compared to the tablets in local retail shops in Iceland
I literally just finished looking into buying a banana pi which is supposedly just as good as the rasberri pi, and even better in a few aspects. However the rasberri pi costs just as much so I dunno
My advice for those who wanna buy shit from aliexpress is sort by rating or number of orders rather than sorting by price
In addition, dont be to fixated on getting the absolute lowest price, it may come from China but it will still be shitty if its the cheapest thing you can find
>VGA to Ethernet
link and or pics plz.
I guess VGA (technically, DE-15) allows for more pins and thus easier POE-type stuff or extra data lines if you were in some bizarro-world where it made sense to roll your own solution.
>remote control RGB LED light bulb
Was great for about 6 months, the fixture I had it in used frosted glass so the whole thing glowed whatever colour the light was, but then it took a shit
>i2c blue/yellow display
I believe it's the same one as the clip's
>8x1GB DDR RAM
half were 256MB and 512MB modules and the other four just didn't work. I got a refund and got to keep the RAM so I guess it wasn't too bad
>mPCIe to micro SATA adapter
My laptop had a 1.8" HDD and I didn't want to bother buying an SSD I'd never have another use for so I just picked up an mSATA SSD and the adapter
>mSATA to 1.8" ZIF IDE adapter
>mPCIe to PCIe x1 adapter
>breadboard jumper cables
>SD card socket
>bunch of 6ft CAT6 and HDMI cables
>BNC to RCA adapters
>2Ah DS Lite battery
Pretty sure they use it because its easier for the teachers.
On the walls next to the teachers desk there is a ethernet port to plug the cable then it runs through the wall all the way to a projector where it's connected by VGA. I could probably make my own but fuck it, it's one buck.
>I guess VGA (technically, DE-15) allows for more pins and thus easier POE-type stuff or extra data lines if you were in some bizarro-world where it made sense to roll your own solution.
It's not for Ethernet over VGA but for VGA over Ethernet.
oh wow. I thought it would be the other way around.
Are you a TA or teacher or something? Wouldn't expect they'd let a student use the projectors otherwise.
Also seems a bit strange as presumably you'd need adapters at both ends (not aware of any laptops that do VGA over ethernet natively, jej). I guess this way you can just buy a shit-ton of cat 5e in bulk and maybe get some cost savings that way.
doesn't test 4k write speeds though desu
4k write >>> sequential
long ago I found a linux CLI utility that would do it but it is now lost to the sands of time. I was benchmarking SD cards for use in my memeberry pi
Hahaha holy shit I've been had
I checked the write speed
Newest one is at a whopping 164 MB/s, around 1/3 of what was promised by the shop, and the oldest at a startling 60 MB/s
It doesnt make a difference though, all 3 computers were unusable, the worst one had a 120 s boot time, and would fire up Matlab in 5 minutes or so
sync; dd if=/dev/zero of=tempfile bs=1M count=1024; sync
This is what I did, I dont know how to manually send stuff into RAM but it sounds simple
Fuck the combined write speed of my 3 SSDs' dont reach the speed of a single 'real' SSD
Fellow cheap SSD: I get 115 MB/s with that code.
system still boots fast so I don't really care. at a certain point I would think I may be bottlenecked by the core2duo and the sata 2 chipset.
update: goes up to ~200 MB/s when I decrease the block size to 64k, 1024 records, ~300 MB/s with 4k, 4096 records. Upping it to 4k, 409600 records (1.7 GB) and I'm back at ~117 MB/s, so that's probably about the steady state.
Looks like it can in fact max out my SATA II chipset when the data is small enough to fit entirely into cache, and only gets cucked by the write bottleneck on large writes. Sequential read is next on the list of things to test
last time (a couple of months ago) I've ordered an RS232 to USB cable. I've been using my colleagues cable to configure Juniper / Cisco devices for a while, but then I got tired and ordered one for myself for 2$.
It was quite cheap, they sell it for ~10-15$ in my country.
i am sorry op those seeds you buy are fake, its common tricking method in those chinchong shops. you will run out "buyers protection time" until those seeds bloom. and seller wants you to give 5 stars.
well, it was less than a quarter, so I guess it's no real huge loss. The guy did send me some pretty bizarre fucking messages though
>and i have a 2 years old daughter and 1 year old son
>1 child per family law
You'd think of all the people in the world, a chinese person would be the least likely to fuck this detail up.
is it really hard to believe that it's a single mother? in China it's very popular nowadays for stay at home moms to buy shit off taobao (Chinese eBay) and make a little profit reselling it to foreigners. the government subsidizes the shipping and all they have to do is drop by the post office and ship the stuff off.
More Japanese, but same difference.
It's an LCD board for an iPad 3/4 screen. £20 for the board, and then £25 for the screen, and I've got myself a 2048x1536 screen that works with my PC
Not recently but I bought a counterfeit gayming mouse (Razer Naga Hex) for about 25$ about 8 months ago.
It totally looks like the original one (razer logo, razer text, ecc) but ofc the mouse sensor is shit (snappy). I use it only for MMOs and MOBAs.
It's hard to do precision tasks like (image) editing or play FPS. I use another mouse for these tasks.
I mean don't they need to be registered to use services like banks or apply for a job? Do they get something a little similar to social secruity numbers in America that you need to have to register for things?
I know it might not be a super big deal to poor peasents but it must affect middle class families a lot.
Pretty good deal, desu.
Tiny noob-friendly microcontroller board that you can program to act as a HID device for little over a dollar
A reversible MicroUSB cable similar to this pic.
Xiaomi Piston 3s
a replacement mouse wheel for my MX518 for six dollars
bought a small chiclet keyboard
really nice for use with stuff like PS4, Raspberry Pi and my servers in case of a power outage when I need to unlock the encryption
most of the other stuff i bought was fairly useless
Kept getting messages for a long time after I bought my phone from AliExpress, and it took months to arrive.
No, I was given four different tracking numbers in total, of which only the fourth one actually tracked anything. It was two months before I could even track it. I wouldn't mind just slow shipping, but the seller was being deceitful on top.
Pic related is only $20 on Amazon
Even the cheapest 55cent CH340 adapters work great with Linux (driver is already be in the kernel)
If you want to spend more get a FT232 knockoff with all the pins like DTR and so on.
tempored glass for my phone
A load of usb to micro usb-b for charging shit, i just leave them all over the house now because i have plenty.
A couple of dust filters for my case fans.
Velcro cable management strips.
3,5" to 2,5" bay adapter
A load of other junk
Heh, I have four of those (Dell mini 910) sitting around the house. The one that only came with an 8Gb HDD was a tight squeeze but the others shipped with 16 Gb and they're only about 75% full.
I mostly set them up with 16 bit emulators + USB gamepads etc and give them away to little cousins/charity.
I found one Samsung 32Gb drive for my personal machine for $30. The holes were in the wrong spacing so it didn't work OOTB but some careful dremeling fixed that.
The economics on those things suck because there were only ever like 2-3 laptops that used that bullshit PATA-over-PCIE interface, so the supply's low. I recommend just getting a $20 64 Gb MicroSD and leaving it in the laptop permanently. If you're adventurous you can try soldering a mini pci socket over the unpopulated WWAN slot and seeing if a general, run-of-the mill pci SSD will work there (more/cheaper options)
is there any service/app that takes list of items and finds one ebay seller that got it all?
i don't want to go to mail 8 times for one simple project
I ordered some <= $5 wired and wireless mice off ebay.
The cheapest wired mice (black on top, sorta see through on the sides, ~$1.59) work great.
The absolute cheapest wireless mice (~$2) suck, do not buy. Those are the slim, super plasticy ones. The sensor sucks.
There are some good options at the ~$3-$5 level. There's one that's a full size mouse with thumb buttons that's pretty nice, and a slightly more expensive slim mouse that comes in two-tone trim (I usually choose the black and green option).
I have played a bit of half life and used GIMP with these, but I'm not a hardcore CSGO autist or legit_photoshop_memer so I can't really compare them for those *cough* PLACEBO *cough* uses. Just feels like a mouse to me desu
xCable magnetic usb charger. just got it and works like a charm.
I am going to buy this one when it becomes available.
A replacement keyboard for my laptop, replacement fan, a couple of Delta screamers to play around with, a bunch of LED/LED tape, a remote RBG controller for an RGB LED tape, copper heatsinks for VRMs... That's it of the top of my head for the cheap stuff. I did buy a Win8.1 tablet that actual runs great (and it's been over a year) and an Android phone, which gets uncomfortably hot when charging, but otherwise runs very well.
Don't. Onda is pretty much the only one worth anything, and even then you have to trawl the net for russian reviews where the disassemble the shit to see how's the build quality etc.
Got this for 3 bucks, ordered another one.
I use it when camping with friends. They were impressed with the quality, that beats their shitty smartphones flashlights.
I was going to do that and then I realized I'm retarded and never touched a soldering kit in my life
I rather experiment on something less important than a populated working mainboard...
Some sellers say 300, 600 or even 1200.
Just try to get one on the 3 bucks price range with a lot of sales on ebay. I recall some seller saying on the item description that he only sold originals from Cree, those are the one you should get.
You can see the light at 40-50m in the mountain at night, pretty good.
Mine is a Thinkpad x200, so SATA 2. SATA 2 maxes out at 3 Gbits/s which works out to ~ 375 MBytes/s . Hence why I said >>52468256 that it maxes out (well, not quite) the SATA II chipset when data fits into cache but larger files are bottlenecked by the steady state write speed which seems to be a little over ~110 MB/s.
I tried switching it around a bit and using dd to read from testfile -> /dev/null and got a very suspicious 2.0 GB/s result which I don't think can be correct.
Just found the linux benchmark utility I used to use -sudo apt-get install iozone3
I drunkenly bought a compact flash > sata adaptor last night, and a 16gb compact flash card, to put in an ancient laptop with a dead hdd. However, said laptop actually needs an IDE drive, so I just went and purchased an compact flash > ide adaptor. It was a total of $20 for all the listed items and I'm probably not even going to bother cancelling the sata adaptor
Apparently, there were exceptions to the law, and they started to formally phase it out last year. And you also were allowed to have a second child if the first was a girl. Now they're enforcing a two child policy.
Has anyone bought one of these things? are they any good?
got a pair of 5m LED strips for 5€ each (i have some leftover adapters and power supplies)
(non-burning) laser pointer with rechargable batteries
a stack of small magnets to play around with and attach random things to random places
I got these. They are $1 each, and I can EDC it by leaving it in a flash drive on my pocket. They work great, but they take a couple months to ship.
I have a SJ4000, it's not bad for 1080p 30FPS recordings. But it's a bit old now. Newer cheap action cameras are capable of recording at 60FPS or at higher resolutions. But many of these newer cams like the Xiaomi Yi come with a shitty app to control the camera with a smartphone ore tablet, so that they don't need a display at the back.
There are also some SJ4000 fakes, so be careful if you buy one in China, I bought mine on Amazon.
It was less than 1 buck and fits in your wallet.
It makes you look like James Bond, but I only use it to open beers.
These things are quite big, so it's probably not worth the shipping costs from China for a individual item (which usually get added to the price). Walmart can just buy a container full of these things, so it's cheaper.
I just found out about the SJ4000 a few days ago. I started looking into it, and there's a huge problem with knock-offs. If it doesn't say SJCAM in the bottom, right of the front of the camera, then it's either the first version (unlikely) or it's a knock off (very likely).
The cheapest seemingly legit SJCAM I could find on eBay was like $50. But there was a seemingly legit SJCAM SJ5000 for $39, so why not buy that?
As far as I can tell, the lowest model SJ5000 (there are three versions) is as good as the SJ4000, but with a Panasonic CMOS.
Now here's the problem: I don't actually know if there's a meaningful problem with just buying a $20 knock off. Pretty sure they won't be firmware compatible, but I don't know that there's any actual *problem* with them, aside from things like screen layout being different in the settings. Maybe the knock-offs don't support some of the SJCAM features, like the dashcam mode.
actually even for non-vape stuff, they are one of the few sites that doesn't lie. If they say something's genuine, it's *always* genuine.
That being said, they do have a lot of knockoffs, but they don't misrepresent what they are, and will write "-style" or something similar to indicate that it isn't the original.
me again. Getting some pretty spooky results with iozone, not really sure how much to trust the program.
Writing huge files (512MB) pretty much lines right up with the dd test at around ~120 MB/s, for any record size tested (64k - 16MB).
There's a pretty drastic bump up to 700-900 MB/s when the file size is below or equal to 64 MB though, so I'm guessing that's the on-disk cache size. The disk itself is rated for SATA III, but those are even faster than SATA III speeds and my chipset on this POS is only sata II anyways. Maybe some strange voodoo caching magic I guess.
Read speeds are incredibly spooky at up to 3.0 G *bytes* per second, so I guess this thing is just caching super well and iozone isn't doing enough to flush it out.
okay, the -I flag was supposed to disable caching but it didn't seem to do so on my platform. I had to run it withiozone -a -i 0 -i 1 -i 2 -s 8G -r 1Mandiozone -a -i 0 -i 1 -i 2 -s 8G -r 4so that the file created was bigger than my ram (4g).
Sequential, 1M blocks gave a write speed of 106 MB/s and a read speed of 211 MB/s. Random read was at 190 MB/s and writes at 77 MB/s
4k block size gave sequential write of 101 MB/s, sequential read of 209 MB/s. Random read was at 20 MB/s and Random Write was at 40 MB/s (higher than read???)
These values are a lot more reasonable. They still don't quite line up with what the seller quoted: (462 MB/s read, 70 MB/s write). I'm getting slower reads but faster writes than he quoted, and it's reasonable to assume my dated SATA II chipset + core2duo might be causing some bottleneck, even though I *should* be able to get 300 MB/s out of it.
Whatever dudes, I paid $30 for it and pretty happy with the result. Feel free to use my iozone commands I posted above, I'm interested both in results from fellow chinkshit or proper Intel/Samsung freetards
I've bought far too many usbs from aliexpress that turned out to be smaller than advertised (and even labeled in-OS).
My fav purchase is probably the card-sized multitool I have. Carry that thing around everywhere without it taking much extra room in my pocket.
I can now digitize VHS and Video8 tapes, at pretty damn good quality.

It's much better than my Murkur Futur.
Depends, I would be careful with stuff that gets in touch with the skin a long time (like bracelets) or gets in contact with food. The only thing I got so far that was really bad in this sense was a notebook lock that smelled of softeners.
Most things you can buy in stores in western countries are the same stuff you can order directly from china. It doesn't matter if you buy it by yourself at Aliexpress or if a importer buys it in wholesale quantities at Alibaba, sells it to a store which sells it to you.
These are surprisingly handy, ripple is a bit high without an extra LC filter though.
Like cheap IEMs like KZ and xiaomi. I have read that they use illegal plasticizers and other chemicals that are not supervised in the factories there for the cheaper goods.
Seems cheap enough. The third pot is for an indicator LED when used as a charger, I cut the trace for that on mine to save battery power.
I bought one at Aliexpress about two weeks ago, should arrive in the next days. I have many of the ones without constant current, but especially for LEDs the a built in current limitation is useful.
Yeah they are pretty useful for stuff like LED's, I used some to make one of those kip-kay infrared video lights as the resistor in series method just gobbled up battery life.
But also you don't have to worry about the chip exploding if you accidentally short the output.
What is the out of the box ripple like on those versions? I had an idea to power a laptop from some lead acid battery's.
I've successfully tried it with a homemade 3 amp buck converter but its not really enough current capability to do anything useful, the test laptop draws about 2 amps @ 19v just sat in the BIOS (with the laptop battery removed).
Highly recommend this fucker over the Zippo branded one. Smaller, 1/3 the price and has the same heat output.
hahaha, no chance. I haven't measure max load current on one but IIRC they say to keep it under an amp or two.
I mostly use it for smoothing and regulating the voltage between a USB battery pack and a 5v chip amplifier with high inrush current.
Without it in series the inrush would cause the voltage to sag enough to reset the amplifier (and also turn off the embedded mp3 player). It would just go into a reset loop, pop-pop-pop-popping until you turned it off.
Also the cheap USB power bank drops the USB output to battery voltage (~3.3-4.2V) ish when you plug in external power to charge, which was enough to disrupt it. This is actually better than many of the other models which will simply disconnect the output when charging.
Putting a hardware power switch and the little buck-boost converter allows me to use the setup like a 'proper' little speaker that can be turned up loud and charged at the same time.
I've measured power usage and I never pull more than ~0.45 amps out of it so I can't say how much success you'd have.
Maybe you can put these in parallel, but I kind of doubt it. Ask /diy/ . This board doesn't understand basic electrical principles.
This fucker is one of those photonicinduction wannabe's but just happens to be a special sort of weirdo too.
He even visited photons house and made a video with him https://www.youtube.com/watch?v=lTHgn6GQeig
Photon must have been internally cringing the whole time.
