Weight
1.5 kg

Unlike cheaper USB ports that only implement links at USB 1.0 standard (12mb/s speeds but state they are 'compatible' with USB 2.0) this is a professional FULL 480 Mb/s port that complies and implements the full 2.0 USB standard. It may also be used to connect to generic USB 1.0 equipment.

The good thing about these hubs is that you can load them up with 49 Bi-Fury miners (around 245 gh/s) and the miners would STILL run as intended. The Hub runs cool but the miners you put in will not, so make sure you use lots of fans to cool them.

COM-PORT Clean Up Trick, by Nemo1024

1. Launch cmd.exe
2. Then run the folloing in the command window:

3. Next launch device manager from the same window by executing

4. Finally, in the Device Manager check View->Show hidden devices
5. Clean-up time. Expand "Universal Serial Bus controllers" and delete (hit 'Del' key and confirm with enter) all devices with greyed-out icon (this section will contain your hubs).
6. Do not delete driver software (leave the checkbox in the prompt unmarked)
7. Repeat for "Universal Serial Bus devices"
8. And finally for "Ports (COM & LPT)"

Optionally go through the other sections and delete greyed out devices: your Windows will be more stable and start faster. Don't worry, if you plug a device at a later point, it will get re-added to the list.

9. Now, plug in all your hubs (without the USB devices) in the topology you wish to use. Wait for them to be initialised.
10. Then plug your devices.
11. Enjoy cleaner and more stable Windows.  ;D ;D ;D

Everyone got their hubs on time and were pleased with the product. I hope to repeat again.

Manufacturer ? Images plz.

No coins yet :) watching...

More info on brand and such, close ups ect, I have not seen these anywhere yet, glad to have em, was getting worried asicminer would/did discontinue theirs.

Your Dipos are killer, industrial strength :)

Hi Folks,

Just thought I'd let you know Ive been in touch with klintay for one of the old Dipo hubs - he told me it might be better to hold out for his new project with is this hub. Really looking forward to getting one and testing it out

klintay any high res pics up yet? :)

The manufacturer is Eyeboot


Here we go... at the warehouse

I have 200+ bi fury usb miners coming soon which i plan to use to test these bad boys...will upload my results soon :)

EDIT: I was mistaken and it was Twin Chip Fury not bi-fury. Twin Chip Fury are pretty big...about twice the size of any other usb miner i have seen.
Will keep you updated if i decide to get them.

Have ordered and paid by paypal - will update with review and some pics on arrival :)

Gridseed compatible??

payment received, will start preparing your package now and update tracking details soon  ;)


yes should be...I have some gridseed 5 chip units here so will test and post pictures of that as well. I am going to run them using bfgminer in scrypt only mode.

I wish you made it a bit spacious between the slots.
Current Antminer U2 has humongous heatsink and the regular 49 port USB hub doesn't have enough space.
I'm not sure about yours. If yours is spacious for multiple U2 it will be a winner.

EDIT: Oh wait, you are going to test it with 200 bifury.
If im not mistaken they're using the same humongous heatsink as the U2.
Can't wait to see how it goes.

Pm send , please answer

Question on the shipping charges.  If I order 4 and regular airmail is it $30 + $20 for a total of $50? Or $30 for the first and $20 each additional hub?

it is $20 for each additional hub due to the size and weight.


good feedback for future units...I will look into this

Do you ship to Canada?  Same price as US orders?  Will you accept Canadian dollars via Paypal?  Looking for one unit.

Yep we ship worldwide. Canadian shipping will be the same as US. Canadian dollars via paypal is fine. I will PM you the details now.

Ordered 3,
1f420335e88fe2300e213d89a12c57b62d671ed6879849a11e074d9616ca16cc

received, i have updated the original thread

Ok, all orders have been sent and tracking info provided.

Felipeo has agreed to test my hub with his bi-fury usb miners and then post some pictures here.  ;D

I can test dualminers, Nano Furry IIs, and Antminer U2s

Payment just made via Paypal with CAD$ as per PM details.  Hope to hear from you soon!

That is good to hear, look forward to hearing the results once these babies are out in the wild :)


Thanks payment received. Will PM you soon.


Felipeo says there should be enough space between the usb slots to fill her up with bi-fury usbs  ;D

I tested the hub with my last 4 gridseed miners that i had lying around house...works perfectly fine. Used bfgminer and set the frequency to 850
They were all hashing away stably at 360kh/s.

Here are the pics:

http://www.batpic.com/images/2014/03/26/1iSqB3.jpghttp://www.batpic.com/images/2014/03/26/20cUN5.jpg

I plan on testing one of ours up to 49 grids if we can :)

Yes, I just waiting for my hub arrive and then I will test it just like klintay post :)


When this hub will be able to run 49 Bi•Fury on full power it will be able to run all of this standard A/V usb miners ;)

Wow. Ordering one of these guys tomorrow.

I will do a full test on NF2's and report.

Thanks Swimmer! I would appreciate feedback and pictures

I am philipma1957  This pc   can't access that account.

not trying to attack or diss the thread as I have 3 of klintay's 19 port hubs.  

If this is using the 24 pin plug's 5 volt to power the sticks you will not do more then 35-42 sticks on almost every single atx psu.   Most modern  atx psu's are 20 to 25 amp at the 5 volt level.

Now I do not know that  since I have not examined one but I do know that the older 49 port hubs from fried cat   had many other issues (bad fuses)

40 amp fuse melted .

And friedcat was wrond to put in 40 amp fuses since almost atx psu will supply more then 30amps at 5 volts.

Older ones do .  2011 on and forget it.    I will go back to my other pc.  the wife is done using it.

This is me on the other pc.

I hope that the new hub uses more then the atx's 5v rail.

These are good hubs. I had one running 49 ant miner U1 around a bit over a month ago. Possibly different manufacturer but it looks exactly the same from what I can see. One of the capacitors popped on my one after about a week if none stop mining.

Here is a video of my one.
https://m.youtube.com/watch?v=LURaT9i8ttI

The video doesn't show the hub very well as it was filmed to show all the devices working. They are all running of a raspberry pi with the power wire in the USB cable cut to prevent back feeding.

klintay, has stated these boards are made by DIPO if so I would think all that is covered, (12v-5v source used and filtered/converted.)

Dunno. I have all Corsair 950tx and up left over from game dev, they have plenty juice single 25/30a 5v rail TX/HX type. 60/80a 12v rail.

Still if this USB board uses 5v off the ATX, for me that is better, as then I can use the 4/6/8 PCIE cables coming off them to run 12v ANT S1's later on.

So I am asking does this hub have its own power regulation ? If so what does it pull 5v or 12v or both ?

Maybe hubs could start using 3.3v rail as those seem to be unused for asic mining.

Nice to have so many miners :) A little dark, shows the activity well.
Looks to me to be close or same hub, but the devil is in the details, One manufacture uses cheap assembly parts, another uses bulletproof overdesigned expensive parts.
El cheapo wins on volume & $, good stuff builds rep, and stands the test of time... But you only sell one a lifetime per person :)

my uncle went bust selling pianos and hammond organs as they don't break and repeat business kind of was non exsistent.

Back to this hub.  I think it would run all 49 ports if you did the girdseeds as the gridseeds are powered and do not need the usb for juice.

I had 11 friedcat hubs  I found I had to swap the 40 amp fuse for a 30 amp.  I found I had 1 atx that ran around 45 sticks with no issues.  I ran ant miner u1's and last summer AM sticks.

I could not run very many of the nano ice fury sticks so I purchased the 19 port ones from klintay.  I like them and have 3 of them.  I am interested to see if these will be as good as the 19 port ones.

I will wait to see peoples tests.

I just ordered 3 hubs

found a good psu for these hubs



http://www.tigerdirect.com/applications/SearchTools/item-details.asp?EdpNo=125449



I had a 650 watter  same make and model it ran 46 asic miner sticks  on a friedcat 49 port hub.


one of these should run 40 sticks no issues this is a quality psu


I found the link here

http://forums.anandtech.com/showthread.php?t=2375729


if you buy through this link I think they get a referral fee

The more i look at this hub i think it is the perfect hub for a big gridseed farm

I use this hub for my 15 piece  gridseed farm

but I think the one above would be better.

LOL….
Before we start handing out accolades for quality
Can I clarify something  once and for all, the 19 PORT DIPO hubs that were 'sold' were actually from a batch that was TESTED, Inspected  and REWORKED by ME!!

RF




No it does not, I am 'intimate' with the design of this hub.

RF

really now? that is the first i have ever heard of this... anyway I think I will let the product speak for itself. I have sent some samples to Felipeo and he will be posting a review. Everyone knows that bi-furies use a lot of juice so lets see how they handle his miners

Looks interesting, but I'm curious about the instructions on the label - what would happen in the event that the host PC was not shut down before the hub was powered off? Say in the event of a blackout? What happens if you turn on the hub before the PC, or turn it on without it being plugged in? What happens if you just leave it plugged in and switched on without being used? Can you share the testing process for the hubs?

Also, I'm a bit confused - does Razorfishsl have any involvement in this sale?

Edit: +1 for answers to the following:

nope nothing at all...just some old partner who has a case of sour grapes


My understanding is that it does not have its own power regulation  :o


Posting pictures of the inside now! Take a Look:

Turning the hub on before the PC could possibly create a power surge that MIGHT damage the usb ports on your PC and/or your motherboard, etc.
Turning it off before the PC has turned off might make Windows think the COM ports are still occupied. Then when you go to turn it on again it can't find your miners or your COM ports get maxed out because of COM port controller limitations.  

On that note, here is a handy trick to clear your COM ports in Windows:

1. Click start → Run → type regedit and click OK button
2. Navigate to HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\COM Name Arbiter
3. Now on the right panel, you can see the key ComDB. Right-click it and click modify
4. In value Data section select all and delete reset to Zero (0)
5. Its 32 bytes with 8 bits in each byte. A set bit makes a port number (1...256) reserved.
6. Close Registry editor and then restart your computer. all COM ports are now Free, you may need to reinstall any winUSB drivers, usb to serial converter, drivers.

okay looks to have better caps then the am 49 port machine.   I can tell you it has better filters for the 5v line and I can see it only uses the 5v from the psu.  

 what does that mean?   almost no modern psu will drive  all 49 ports long term.  but 40 to 44 can be done pretty easy


 can you show a side view of the caps that feed each usb port.

and can you show a side view of the caps that filter the input volts. 

I would like to see the  make and model of them.


still these are much better constructed then the  49 port hubs from am.

I am getting 2 of these  nano sticks this week.


http://moonlightminer.com/  

 I will test them on my 19 port dipo.  I hope to use these with freq 54 and clock to 5gh.

since these are wide you can only fit 24 on this 49 port hub from klintay.

 but I really think this hub will run  gridseeds great I even think you could do all 49 ports.  since gridseeds are powered devices.

I just thought of a great way to use this hub 20-24 gridseed miners and 20 -24 2 chip nanofury /bifury usb sticks would be a perfect setup.


you could run 20 x 350kh = 7000kh in scypt  and 20 x 5gh = 100gh in btc all with this hub.

this would let you use most modern psu's since the gridseed is powered via 12v and if your sticks are too big use the tight spots for the gridseeds..

   I have 15 gridseeds on line  using this hub

 http://www.ebay.com/itm/90W-power-20-port-USB2-0-HUB-USB-HUB-Industrial-grade-HUB-for-Bitcoin-mining-/251478255398?pt=US_USB_Cables_Hubs_Adapters&hash=item3a8d45a726


and I use 3 of the 19 port hubs. for usb sticks.


 but if i was to get this I would mix the gridseeds and the usb sticks on this 49 port hub

seek and ye shall find: 5V  -  45A PSU right now on ebay. $52 usd (exclusive of shipping)

The SHARK 1000W Black Gaming PC ATX

The fact remains that the factory told me that this can take 2amps per port safely as the limit. I will wait to see what feedback we get from consumers when these are actually tested.
 

  I would love to see bigger photos of these two.  I see 1 big heat sink off the usb port branching to 7 big heatsinks.

I believe that would be the usb  controller chips.

I see 4 filter caps from the 24 pin out.  after the filter caps I see no voltage regulator or converter chips.

 so I have to think it just uses the 5 volt lines and no more.

LOL……….

Well since you have now made it a question of my Integrity on this forum….
The first you have 'heard' of this… well yes I suppose so because the correspondence was written or texed, so technically you 'read' it not 'heard' it, for god sake just man up there is no shame in admitting it.

For the record
If I had not checked and spent several days reworking those 19-port DIPO hubs that you sold on this forum, you my forgetful friend would have been royally FUCKED…

There was a parting of the ways due to your 'business ethics' that is all, I also have the right to dispute any false statements to protect my reputation.


RF

That is simply not true. You can get high and mighty all you like but you have never shared with me any information about how you "reworked" the 19 port hubs as you say. So why don't you be specific and explain to everyone on this forum and myself included. All you ever did was get new power cables sent because the first batch was defective. That hardly counts as reworking. In fact you told me that the hubs were of very high quality and needed no extra work. This is a case of blatant manipulation. If you look back on RF's posts you will see he has a habit jumping in on my threads and saying random crap.  

Also seeing as you want to pull up personal info for everyone to see...we parted ways because you couldn't setup a simple website and operate it properly...have you forgotten the paypal split payment fiasco? I told you to contact paypal and speak to them about it and 5 weeks later it was still not working and finally you realised that you should have contacted them to begin with. Or the time i gave you a WORKING blue fury miner (by accident, i thought it was DOA unit sent back) and after all your "tests" you were convinced that it didn't work. Yeah this guy is some sort of genius but he can't get a simple usb miner to work that fucking works.

Piss off RF, this thread is for people who are interested in buying the 49 port hub. Not for them to listen to you whine like a little bitch.  

The first 4 caps are 16v 470uf capacitors, the second set are 16v 100uf (Chong X), each usb port also has one (16v 100uf), appears to be 8 usb controller chips as well

OK…..
So here we are, after my last post  clarifying the situation:

Show and tell
1. Further mis-representations: If someone came to you and asked you to setup a  system using PP split-payment API, where they received 50% of the money for physical goods they did not ship… how long would it take 'you' to setup such a potentially fraudulent system, or would you just keep dragging it out with excuses?
2. Would you setup a website on a domain name and server controlled  by a guy you only just met, who openly boasted about HOW he fucked his 'book selling ' partner over and wanted to setup a 'limited liability company in Hong Kong' with you…. ?

Personal character
2. Harassing phone calls to my mobile phone, sometimes as many as 5 a minute, because  the curtain has been pulled back in OZ.
3. A definition of what "rework" means http://scn.sap.com/people/rupesh.brahmankar3/blog/2013/07/06/rework-in-manufacturing (http://scn.sap.com/people/rupesh.brahmankar3/blog/2013/07/06/rework-in-manufacturing)
for those who don't understand the difference between 'rework" and Having to open, inspect, remove,repackage and test cable sets then having to completely repack goods.
4. Offensive pm's + Further falsifications (it is the first I heard….), then WHY did you state it was TRUE in your PM). (see below)


6. Yep the 'blue fury', go read up interview techniques and evaluating potential business partners, with this simple but effective test I get a complete breakdown of a persons 'claimed' area of expertise.(I could just have used google!!)
 Did it NEVER enter your thought processes of how at 21 I was the technical director of an electronics company turning over $20million a year If I was such a 'fuckwit" with electronics?
Correctable traits
7. A complete inability to articulate conversations as an adult, with valid point of contention.
8. A complete inability to get my name right..
9. The use of 'shill' accounts to promote himself in his own threads.

AGAIN I will state this:

There was a parting of the ways due to your 'business ethics' that is all, I also have the right to dispute any false statements to protect my reputation.

I think with each passing day, this conversation justifies my decision.


RF

The truth:

What did you mend on the hubs? Why are you avoiding the question. My message says clearly that you never told, wrote, mind melded , etc any info about reworking the hubs to me. You did look at them because we bought them together and you did say that they were good. So did I.

 :D :D :D :D :D :D :D :D :D :D

You still have NOT said what "rework" you did on them.

I won't be replying or speaking to you any more. I only have one account on here by the way and no shill accounts so i think it would be amusing for you to point them out. Therefore this is my LAST message, I CHALLENGE you point out my "shill" accounts. Everyone will see that you can't and that you are in fact full of sh##!

The End.

Here you go mate:

From the tone of it, sounds like razorfishsl is doing a bit of harassing...
My personal trade experience with klintay was positive, and the 19-porter that I got from him is still happily hosting 15 Ants, 3 BEs and 1 fan, 24/7.

klintay, might I suggest you start a reputation thread here:
https://bitcointalk.org/index.php?board=129.0


There is another trick, that I outlined here, which is safer (does not involve messing with the registry):
https://bitcointalk.org/index.php?topic=300638.0

In terms of the ongoing feud evident in this thread, the mention of 'shill' accounts might have been a reference to the comment I made in the old Gridseed GB-thread that klintay had going a few weeks back, professing my willingness to send klintay money.

I hereby declare myself to be a separate human-being from the one we refer to as klintay.


Hope everyone is okay with that.

Just going to copy the above:

"I hereby declare myself to be a separate human-being from the one we refer to as klintay."

I state this:

Take your childish bullshit elsewhere.

Just ordered 1 hub with expedited shipping.

Thanks!

I guess that might be for the best. 


I have updated the thread to include your workaround instead. Definitely safer, plus no rebooting is a time saver as well.


My sentiments exactly :D :D :D



Payment received. Will get onto this ASAP  ;)

klintay:

Can you confirm that only the 5V lines are used off the 24 pin connector? If so, wiring up something like this:
http://www.mouser.com/images/meanwell/images/NES-350.jpghttp://www.mouser.com/ProductDetail/Mean-Well/NES-350-5/?qs=sGAEpiMZZMsPs3th5F8koPF2exM897jTfzSnH%252bHf3Vo%3d (http://www.mouser.com/ProductDetail/Mean-Well/NES-350-5/?qs=sGAEpiMZZMsPs3th5F8koPF2exM897jTfzSnH%252bHf3Vo%3d)

would have more power and perhaps less mess. Why pay for 100's of 12V watts when you don't need them.

-a[g

I bought a 19 port hub from klintay before, I also sold him 20 blue furies (all working.) Or was it 40...

I might get one of these 49 port hubs, but I don't know what to plug into them since I don't have any miners at the moment.

I like the design of the 19 port hub, and it uses 110/220v directly (maybe the PSU is built in the thing, I have not opened it yet.)

klintay, let me know when you have a 130+ port USB hub that gets power from the wall. heheheh.

Click on my signature for something to put in the hub.  :D

Thanks! Now to do some calculations about ROI ... ... hehehe.

Using a 49 port AsicMiner Hub running 18 NF2's at 80 Gh/s.
Could go a bit higher, but don't want to push it.

Waiting for this hub.

Just got my 3 hubs in, Shiny!

Ordered!

I'll let you all know if the 5V supply works.

It is definitely pulling power off the 5V rail so most likely you will get 20-30 sticks at an 1 amp or  35-44 at .6 amps
Will change the next batch so that it draws power from the 12V or 5V + 12V rail! Possibly going to make spacing bigger as well.
Feedback for future designs in welcome!


Good Luck! If it works that could be a deal breaker :)


Great! That didn't take too long  :D

klintay samples already waiting for me, thanks!
I just can't wait when I will test It, will get back home on Monday  ;D

Nice weekend for you all :)

Hello Miners.  I just wanted to share my experience so far with the new Klintay/Dipo/Eyeboot 49 port hub.  I was recently burned on a group buy on a U2 Antminer, so I was a bit weary of another buy.  Still wanted the 49 port hub though, as I didn’t like the fact that I was maxing out my USB hubs making the power bricks run quite warm and it was a messy layout.  Paypal was accepted (even in CDN $) for payment so at least there was some insurance to dispute the charge if things went south.  Looks like the seller had some history with actually delivering the smaller industrial looking hubs, so I was hopeful.

Payment was sent late the evening on March 25.  Package was dropped at Hong Kong post office on March 27.  A tracking # was given the same day.  Package arrived at door in Calgary, Canada April 2.  Past experience with shipping from Asia indicates that this was pretty fast shipping!  (This was for the registered/tracked regular/non-express shipping option)  For reference: I'm still waiting for some cheap ebay nick-nacks from China that were ordered March 18.

Package acceptance process required a signature and ID.  Was very happy and surprised to find that no customs duties were charged by Canada Post at all.  The package honestly stated a $180 USD value.  Usually the minimum $5 brokerage and Canada sales tax applies on packages over $25.  There is an exception on duties for computer parts though, so I guess they waived the rest.  What ever happened, it worked for me!

The shipping package was large.  At least triple the size of the actual box of the hub.  Though, the shipping box was filled with cardboard spacers to prevent too much clunking around.  The actual box was the same as the photos with no markings, a plastic handle and nicely cut foam inserts for protection.

Initial inspection showed a nice product.  Same as photos, with flashy orange-yellow colour.  I did find a missing top metal nut on the front panel, but found the nut in the plastic bag that the hub came in.  It was easily attached back by hand.  The rest of the nuts were tight.  Perhaps this one was not fully attached at the factory and came loose from the vibrations during shipping in numerous modes of transportation.  The included translucent blue USB cable was separate from the hub box, so it was probably added on from the seller.  It seems of good quality and a good length as well.  

Now connecting … drum roll please.  It works!  I fired up my Raspberry Pi with a newish version of Minepeon running BFGMiner.  I’ve got nine U1, one U2 and one Arctic Breeze USB Fan connected to the hub, it’s powered by an EVGA 600W PSU with a 20 Amp 5V rating.  I know it’s under-rated if I want to load up the hub, but it’s sufficient now.  Overclocking the miners has mixed success, as soon as I go to 2.2 GH/s and above, my error rates go to 10% and up.  This negates any overclocking benefit.  Though I must admit I didn’t have much time to play with overclocking.  So far I’m happy to get 2 gh/s per unit and next to zero errors.  This is probably normal and not a caused by the hub, as I had similar results with other hubs.

Future plans?  I just found a couple of salvaged no-name PSU’s that are nameplate rated 47 Amps on 5V (500 W max total unit), so I plan on using this bad boy PSU if I manage to collect some more USB miners.  I’d also like to install the hub vertically on my basement wall to open up space on the floor.  Looking forward to an even  cleaner looking install.  Cheers.

Edit: There seems to be a nice spacing for the U2 Antminers.  I only have one so far but it looks like enough room to start filling out the hub with fans facing down on them.

Hi,

   any stock left for this cool hub?

   Btw, anyone tried powering it up with an ATX splitter? Does it work that way?

T-Bone-bitcoin, thanks for giving such a great and thorough review.  Glad to hear it arrived safely and in good condition (apart from the one loose nut). Hope you an get some more miners soon as well :) About the large box, I had ran out of my smaller boxes that day but didn't want to delay your shipment so used what i had on hand and put the cardboard spacers in to prevent any possible damage from movement. Yep I am adding USB cables for everyone who buys so that you don't have to mess around taking them from your printer etc at home. I just picked up 100 x black USB cables of a nice quality in China that are 3 meters in length too so everyone will get one of them now too. The spacing between the ports is quite good but could be better in my opinion - a possible improvement for future models?.  Maybe 40mm x 40mm but that would be one big hub!


Yep still in stock at the moment. Let me know how many you want and chosen payment/shipping method, etc. ATX splitter should work as long as you still use pins 21,22,23 and 6 for the 5V. Goodney is looking into modifying a NES power supply which would be a lot cheaper and more efficient than buying a normal PSU.

Great, please post pictures when you get a chance   ;)

I just recieved three of these today, these are seriously awesome hubs

klintay:

Design suggestion for next revision. Built in fans! Mounted in the top of the hub facing up so they blow past the miners. Maybe with an on/off switch for each column of fans.

Nice idea!

I have been thinking about the problem of not enough Amps on the 5V rail for some users. How about something like this:

It lets you connect up to 3 x PSU to one 24P ATX

http://www.batpic.com/images/2014/04/09/57_1.jpghttp://www.batpic.com/images/2014/04/09/57.jpg


 :D :D :D :D :D :D :D :D :D

Unfortunately that Adapter only jumpers the 2nd PSU to turn on..
There's a no wiring to the other female atx related to 12v or 5v rails.
I think the best bet is to modify the hub so that it takes 12v instead.

Would be helpful if goodney would provide schematic to wire 5v led/cctv switching to the atx.

I second that! I just bought one of these on ebay:

5V 50A 360W DC Regulated Switching LED Power Supply

http://r.ebay.com/Apne0O

Need some help rewiring the 24P cable  ;)

Once I get my hub (from Hong Kong), power supply (from San Jose) and ATX connector (from Hong Kong), I'll do a schematic and pictures. ;-)

Just got my 49 port hub in and hooked up. Klintay had great communication and sent me the tracking number promptly. He even followed up to make sure I received it. I'm happy with both klintay's service and the hub itself, which feels very solid and works as expected. So if anyone is looking for a USB hub with a large number of ports to connect many Gridseed ASICs with, this is an excellent choice.

The hub:
http://scryptery.com/assets/img/hub1.jpg

Fits neatly on the bottom row next to the power supply:
http://scryptery.com/assets/img/hub3.jpg

It completely replaced this mess of wires!
http://scryptery.com/assets/img/hub4.jpg

You're plugging in 40 gridseeds? They don't need power though, since they are externally powered, so how many amps of power supply did you use for your 49 port hub? I might get one. Still thinking. LOL.

Gsupp, they are some great pictures! Thanks for sharing  ;)

What kind of controller are you using for those 40 units? Raspberry Pi?

This ... is freaking awesome.

Damn!!!!!

Correct, I have 40 gridseeds connected. They get their power from the 12V barrel plug, so there doesn't seem to be a power shortage on the USB hub. The power supply I'm using to power the hub and 40x gridseeds is:

EVGA SuperNOVA 1000 P2
http://www.amazon.com/EVGA-SuperNOVA-Platinum-Certified-220-P2-1000-XR/dp/B00EKJQM5E

While it's probably overkill, I had it around from a previous GPU rig and the platinum rating is nice for lower power usage.

-gsupp

I'm using a Linux machine running Ubuntu 12.04 and cgminer 3.7.2 compiled from: https://github.com/dtbartle/cgminer-gc3355 Works like a charm! Super stable, no lockups or reboots required.

Thanks!!!  ;D

Top pic (also showing Klintay's awesome 49 port hub):

I am going to copy you ... just ordered my first gridseed today lol

Saving up for that board.

Great price too best on the net!

Looks fantastic!

If you still have any left - I would like one!

Please message me!

I will also message you.

Best price on the net that I can find!

Special price for the bitcointalk community  :D :D :D

There is still stock, bitcoin or paypal payment are both accepted.

I can confirm that the $45 5V 60A power supply works with this hub.

It's late here, so pics tomorrow!

Brilliant! I have one on the way. Going to get another now :)

OK, as promised! First the money shot:
https://i.imgur.com/deB1jzbl.jpg

The rest of this post are the steps I took to make this work. If you're going to try this you should at least know how to do basic soldering, crimping and heat shrinking of cables.

One thing to note is that it looks like the power LED on the hub is powered from a 3.3V line, so it won't work if you go this route.

1. Here is the ATX pinout. We'll be connecting all of the black and red positions to the power supply.
https://i.imgur.com/nghItQJl.jpg

2. I got this Meanwell 5V 350W supply:
http://www.bravoelectro.com/media/catalog/product/cache/1/image/265x/9df78eab33525d08d6e5fb8d27136e95/SE-350.jpg
The price varies all over the place, and there are many similar supplies on ebay available out of China. They all look about the same, but getting one from a reputable company for only $45 was pretty nice.

3. I used 18 gauge wire. 16 would also be good. Don't go any lower than 18!
https://i.imgur.com/AjIF83rl.jpg

4. Get yourself a 24 pin ATX connector, mine came with pins which was nice:
https://i.imgur.com/kNMavPLl.jpg

5. Attach pins to eight black wires. Here you can see the crimp:
https://i.imgur.com/Z5D12k6l.jpg

6. Because I don't trust crimping, I always solder these type of connections too:
https://i.imgur.com/FimSifdl.jpg
You can see the copper wire is now covered in solder and very strongly attached to the pin ;-)

7. Add some heat shrink. Don't put the heat shrink too far down the pin or the pin won't go in the socket correctly.
https://i.imgur.com/UUaBxZXl.jpg

8. Insert the wires into the connector following the pinout above. The pinout above is looking at the *face* of the connector, so you'll have to take that into account. My connector had pin numbers stamped on the back so it was easy to get right.
https://i.imgur.com/NZjYP9Ul.jpg
https://i.imgur.com/zZ6QThrl.jpg

9. Repeat with red wires:
https://i.imgur.com/9NRFvj6l.jpg

10. Now on to the AC power. My supply had a "L" for line, "N" for neutral and GND for ground for the AC connection. Here in the US the line wire is black, the white is neutral and the green is ground. Please get this right! Also, I'm using ring lug connectors. Again, I wan't everything to be very well connected. Ring connectors can't pull out like spades or just bare wire, so I like them best.
https://i.imgur.com/OLFDyDHl.jpg
https://i.imgur.com/UoSQQhpl.jpg

11. First I hooked up the AC line to the proper terminals and then I connected a DMM to the output.
https://i.imgur.com/wiP6YNol.jpg

12. Looks good! I adjusted my supply to 5.2 volts. USB spec is 4.75-5.25 and the slightly higher voltage will result in the miners using less current (amps), which is good.
https://i.imgur.com/Mr3nH7Tl.jpg

13. Now I added ring lugs to the ATX cable. There are only three output terminals for + and - on the supply so you need to balance the wires as best as possible. With 6 red and 8 black this works out to 2,2,1 and 3,3,2 for red and black respectively. Solder these connections too!
https://i.imgur.com/kbOMN8El.jpg

14. All hooked up!
https://i.imgur.com/OGGce74l.jpg

Really Nice How-To,  Thank You - That will help out Alot !

Trying to order on the site and it is not letting me order!

Sent a PM.

Cheers goodney thanks for the writeup

Wicked guide, goodney!

Going to nip out and get a soldering iron now. wish me luck! Those cctv psu are cheap and reliable  :D


All fixed now. Please try again.

If I'm only going to plug in 49 gridseeds, I don't need such a massive power supply huh? @gsupp or anyone, what ATX PSU are you using? I figure anything that has at least 20 to 30 amps on the 5 volt line should do, so even a 400 ~ 500 watt will work?

We used a HX1050 we had laying around, powered and ran 32 grids off a rPI without a problem. Just dont power the PI from the hub, gets angry.

Also I ordered 5 more because I and my customers fking love these hubs.

EDIT: upon checking the tracking, they are already out for delivery. Holy shit less than 48 hours from HK > here, I will take it!

Great job!

I don't use that hub, or hubs at all.

Just wants to congrats for that job. (There is a lot of scary stuff here....)

Made on 110%

 ;)

I have a few lying about.

 send me a pm.

 looking to clean up the  house. 

I forget if you are in the USA.

I'm personally using an EVGA SuperNOVA 1000 P2 Platinum power supply to power 40x Gridseeds (at 360Kh/s each / 850mhz core) and the 49 port hub from this thread. I made PCIe to barrel connector adapters to power the Gridseeds and the ATX connector powers the USB hub. My kill-a-watt meter shows 370 watts used at the wall, which includes a box fan set on low. So the power supply I'm using is greatly over-sized.

Yeah Goodney did an amazing job...i am going to look into getting his cable mass manufactured in a factory :)

Sold out a the moment. Will update again once new stock is available.

Any idea on ETA of new stock? Thanks.

Next week  ;)

Around the 7-8th May

Looking at buying a power supply like the Meanwell switching power supply on ebay, which seems to be cheaper when you consider shipping to Canada, which is usually cheap from China vs. the US.  Any one have any advice if I should risk it with a no name brand ($35.50 CDN) vs. the Meanwell ($57.50)?  The 5V 60A unit should be pretty oversized for my needs, so buying a cheaper ac/dc transformer might be okay, so long as it not DOA.

My existing ATX is rated high enough but the voltage goes down to about 4 volts when loaded up and my USB antminers (2 gh/s) are running at about 0.75 amps each.  I'd like to get the voltage up to 5.25 and get the amps down for better efficiency.

Any ideas for cable?  I'm looking at a 24 pin 18AWG extension cable for under $10 then hacking it up for red & black wires only and installing the ring connectors.  Can't find too many places that offer 16AWG wire for an extension cable.  Might have a lead at "Shakmods" in the UK, but might be expensive to ship.

Any ideas for the power cord to the plug?  I'm looking at cutting off the cable from a old power bar.  Anyone know what the minimum wire size should be?

About the wires, there are 5 red and 8 black.  Does anyone know if some of the black cables are not used by the hub?  You would think the wires in would match the number of wire out.  I just think that 8 black wires is overkill if there are 5 red going in.

Anyone know if the current will be balanced on all 5 reds?  Is there some kind of 5V bus on the hub going in, or does each red wire feed specific ports only? 

If anyone has any questions for me, I'd be happy to answer.  I've got a raspberry pi running a bunch of U1 (~9) and U2 (~23) ant miners on the 49 port hub.  I've also got a kill-a-watt and a usb meter with voltage and amps display. 

Found a Meanwell SP-320-5 for $33 USD on ebay.  Hopefully the voltage can be cranked up nicely.

Found a 18AWG for $750 USD also on ebay.  Should be okay for the load.

Some of the cheaper 650 watt ATX PSUs have 45 amps on the 5 volts. That's more than enough for most uses of the 49 USB ports. Right? I mean, maybe not for 49 hex miners or something absurd. (Those should really have external power as well.)

I do have an older 500W ATX rated 47 Amps at 5V connected now with about 35 usb miners.  My usb meter is showing 3.95 Volts at the usb and 150 Watts on the wall.  Hashing fine, but getting a little scared if more the voltage will drop even more, causing the amps to go up causing more heat then is really necessary.

With a newer ATX, might get better voltage regulation but most newer ATX's have low 5A ratings.

I am getting a ATX LED ringed power cable mass produced, like the one Goodney shows how to make, so that everyone can use the LED power switchers. They are really cheap. I got 60A 5V one for $40 usd.


16 gauge wire should be good, don't go lower than 18 gauge


There is a 5v bus that balances the red wire feed. Taking a look at this picture, I can only see three x 5v pins that are actually used on the circuit, though i need to confirm this, they are pins 24, 22 and 21. All the other pins appear to be grounded only.


http://www.batpic.com/images/2014/05/06/DSC2505.th.jpg (http://www.batpic.com/image/jHZ)

I'm interested to purchase both the new cable and hub when they are in stock.

BTW this is the correct power supply, yes?

http://www.ebay.com/itm/5V-50A-360W-DC-Regulated-Switching-LED-Power-Supply-CNC-WITH-CE-/160802119217?pt=UK_BOI_Electrical_Test_Measurement_Equipment_ET&hash=item25708d9e31

That is the correct power supply. I will have new stock on Monday. Will post more details about the cables as well as i get it.

Count me in on some

How many rails does this have?

Also any recommendations as to which one would work best with this hub? Looking to run NF2's

http://www.aliexpress.com/wholesale?SearchText=5v+60a+350w+power+supply&catId=&initiative_id=SB_20140509060544

It uses the 5v rail, there are five x 5v pins on a standard ATX. The hub uses all of them. I would suggest any of these:

They all give 60A on the 5v which will be more than enough to support a hub full of 49 x NF2s

The ATX to LED power supply cables are starting to be manufactured on Monday, and will be ready in about 10 days time (at the latest, hopefully a little faster). The final price is $6 usd each and the length will be 100cm.

New stock arrived for the 49 port hubs yesterday so sales are open again, see first page for payment details  ;)

Just a heads up on this power supply. I ordered one but received a different unit that has 5V rated at 30A. The unit in the auction listing is model ATX-1000-N12S and is rated 5V 45A in the auction specs. The unit I received is model ATX-1000N.  I'm in the process of returning this unit as the vendor has offered to replace it with the correct one listed in the auction. If you order one of these, just make certain the seller understands you want the correct unit.

Update: Received the correct replacement PS from the vendor today.

sent payment  :D

Price is a little more but shipping is a better price but ships out in 40 days

Hello everybody,

I am Zeta from Holland, and I run some small mining rigs as early February 2010.
The problem started whit the fist batch of Block Erupter usb Miners I got in 2013 (100 of them), The 10 dollar USB Hubs from eBay give all kind of problems, power loops that damaged the computer electronic circuits. Not stable whit more that 10 miners.
After that i Got some Drillbit and Fury miners, whit the anker hubs. The hubs managed to stay alive but were not stable at all.
In January i Got some new miners, good for lot of amps at 5 volt (over-clocked), this time i ordered a $pecial Block-Erupter USB Hub whit 49 ports.
The Next view days the whole hub is getting hot, and i needed extra cooling fans to keep the setup stable (Noooizzzz), after a week the usb died and I was broken beyond repair >:(

I got in touch with Eyeboot true this Great Forum, He told me I Needed a Industrial graded Hub from that many Amps and he sold me couple of His Orange USB hubs.

This Hubs are GREAT!  I loaded the new hub whit Overcooled Miners.
Its Running 100% Stable, No burny smells, No magical smoke leaking out of the Electronics, Its running Stable as it can be.

So If you looking for a Stable Hub, Go for The Eyeboot - Dipo-Elecronics 49 Port USB HUB.  Let the Block-Erupter hubs, and the 10 dollar usb hubs from eBay for what it is, Save your selfs lot of frustration and go for the Industrial Grade ones.

Thanks Eyeboot for all the help you give me whit my mining problems I had.

My "out of the box" Video:
https://www.youtube.com/watch?v=AOsCHuzzlfk&feature=gp-n-y

Payment received. Package sent today by one of my workers. I will get the tracking info for you shortly.


It says shipping by EMS, that is usually really fast (like 5-7 days max). I think the 40 days might just be to cover the seller.


Glad to hear you like the hub  :D :D :D :D :D They are really durable and take at least 1-2 amps per port without burning down someone's house

huh, sorry to hear that...when the ATX PSU Switcher cables are finished, people can buy any standard LED PSU instead which is considerably cheaper. Least the vendor is going to replace now the mistake has come to light.

Have to wait to see how the return goes. Any idea on ETA for the Switcher cables? Will they use 16 or 18 guage wire? I'd like to order a hub, but want to wait till the cables are ready and get both together.

FYI If you're looking to order this, looks like the merchant has shipped my power supply already!!!

The cables will be ready in about 7 days  ;) We are using 18 gauge wire. Also making some modifications to the hub so that power on LED will still work even with the switcher cable.

Awesome! When can we order the cables?

I can stick 49 U1's in this hub and not have it burn right?

Will the hubs still work with ATX PS after the mods for the Meanwell cables?

Yes! the greatest thing about this hub is that it runs cool. The ports themselves are designed to take in 1 - 2 amps per port without damaging the integrity of the hub with heat issues and such.


This was a concern of mine too,  but the factory has assured me that the new modified hub will be compatible with ATX PS or LED switcer + meanwell cables
:D :D :D :D :D :D


As soon as there is confirmation that production is on schedule then will open orders for the cables. I will get more information on Monday so can update the topic then. The price of the cables will be $6 usd each.

YAHOO! Got my hub, let us know when we can order the cables.

I'll gladly prepay if this speeds up the turn around time, lmk

Thanks again

I went to the factory yesterday, here are some pictures of the cables being prepared by old Mei Mei (see has nimble fingers):

While production has started, unfortunately it is behind schedule a little bit but I can guarantee the cables will be finished and ready to ship by the end of this month. Turn around from the factory to my warehouse is 1 day.


Glad the hub arrived safely. We can start taking pre-orders for the cables now.

We will be shipping cables at the end of this month!

Nice job on the custom cables!  It's hard to beat on price point.  Would buy if I didn't already make my own.

Was able to use a stock 24 pin 18 AWG 30 cm extension cable (ebay $7.50 USD shipped  or $10 CAD local) + a $4.00 CAD termination mixed pack from Lowes.  As a note, be aware that the connection/termination parts shouldn't be over 8mm diameter to fit into a meanwell power supply terminals.  Also when hooked up, it's always on, no matter the position of the power switch, unless you pull the power on the meanwell supply.  You also need to be very careful about which cables you terminate together and where.  No biggie if you double check everything.  Also with the meanwell, when adjusting the voltage, don't push too hard on the adjustment dial with your screw driver.  I pushed too hard and broke the connection.  Luckily I was able to reconnect by pushing back down.

My meanwell with power factor correction (99% pf) and voltage adjustment to 5.2 V was able to save 10% of power usage over an ATX supply with 35 usb antminer sticks.

That looking pretty good, well done job!

I've had my new stock of 49 Port USB hubs modified so that the LED power light will work with the meanwell power supply but unfortunately the hub is still always on like T-Bone said so be careful. If you are using a normal PSU then it is not a problem.

:D :D :D Its safer! They arrive on Monday morning and the cables in about 8 days.

In the future, let me know if you want the modified hub modified to work with the LED PSU switcher (i.e. LED light works) or just the ordinary hub.

As a follow up.  I now have 49 usb antminers (9 U1 + 40 U2) running on the 49 port hub.  Dunno if anyone has confirmed it yet.  Running good!  Fun to see all the LEDs blinking away.  Lots of space for the U2's for cooling.

The voltage adjustment on the meanwell supply makes a bigger difference with 49 miners.  You just need to be comfortable with a bit of electrical work.  The 5V wires do get fairly warm when you run about 200W, so I tried to point the meanwell fan to cool the wires too.

If anyone's looking for a PSU to keep things simple and avoid any electrical work (ie. meanwell).  I have a couple of used ATX PSU's rated at 5V@47A listed on ebay for sale.  Just search for PSU 49 port hub.

Also noticed that Minersource has these hubs for $140 and U2 miners for $12 now.  Not bad. Last time I checked though shipping costs to Canada from these guys is very bad, as they don't have USPS economy shipping.  Probably better within US.

Could you post a link to your ebay listing for the PSUs?  ;)

Bobsag3 owns Minersource, he is a trust worthy guy and provides good service. There is a special deal with the hubs at the moment so I would definitely suggest them to anyone buying from within the USA.

Also the cables are now FREE when you buy a hub from me :)

Here is the thread about the hub:

https://bitcointalk.org/index.php?topic=640122

Ok I got the hub, cord and mean well power supply but I'm having issues.

I have a multimeter but I'm a noob, how do I test the volts on the meanwell?

I see where to adjust it but I keep adjusting it with no change

Help!

Here is a pretty good how to guide on youtube:

http://youtu.be/4e7gcpCv4ew

Remember when you finally connect it all up, the hub will be always on if you use a meanwell regardless of whether the power switch is on or off.

A few pics of the custom cable and the 49 port hub.  My own cables (... that I made myself) had a problem and one of the wires came off the 24pin connection.  Ordered from Klintay as it was cheaper vs. making on my own again. Anyway, seems to be good to go again.  Cheers.

Sweet! Glad to see the cables working nicely  ;)

Anyone who buys a 49 port hub from me can get a Meanwell ATX cable free this week  ;D ;D ;D ;D ;D ;D

Super cool pictures mate. We are thinking of improving the hub design so that individual ports can be reset via scrypt.

Nice rig  8)

What mining software/hardware combo are you using? Mind sharing command line specifics? TIA.

We have a sale on from 28th August to September 30th:

BTC ONLY $110 per hub!!
PAYPAL ONLY $115 per hub!!

I have this 49 port hub for 8 months, really happy with it, it`s rock stable running my old dual fury`s  :)

Can I use a Maxbron 1000W to power this? I tried doing so and it didn't work. I read above that someone is using the 12V barrel. What is that?
http://www.amazon.com/MaxBron-80PLUS-Bronze-Modular-B1000-MB/dp/B00F3ZNDME

Can someone link me the correct power supplies for this on Amazon? I have some gift cards that I want to use up.

Thanks!

EDIT: Would this work?

Yes the mean well is the best one to use. Also you need this cable:

or

I am putting them on amazon soon.

I tried ordering from the eyeboot site. The States/Providence won't populate for United States. I was using Chrome.

problem fixed. Please try again.

nice to see it on Amazon..  thanks.. :)

Hi guys!

let’s first introduce myself, I'm Thomas from the Netherlands. I’m new to this forum and I registered specifically for this question.
so I’m really interested in this hub, but not for my mining, but for work.
for my working environment I’m using alot of iPad’s, the iPad’s need to be configured and if possible charge simultaneously.
and I hope you guys can help me :)
what I need to know: what is the maximum output of the usb connector, on the site of eyeboot.com they saying a output value from 0.5A till 2A.
Sadly I need 2.1A to charge an iPad :(
So I hope that maybe one of you guys who has a iPad can please check if your iPad is charging by using this usb hub?
if so I can save myself about 900 euros

Thank you very much in advance for your answer,

Thomas

Yes it can charge most ipads but not the new ipad air because that requires 2.4 amps. All other smart tablets are fine.

Hey guys,

Will this work on a Corsair 850w PSU?
http://www.corsair.com/en-gb/hx-series-hx850-power-supply-850-watt-80-plus-gold-certified-modular-psu

I have a few in the office, and wondering if this would work fine on the 49 port without making any modifications?

Yes it will work. What do you want to use the hub for? How many amps per port do you want to supply?

I am reposting the pics for gsupp as the original links are broken and they are friggin awesome pictures. Enjoy  ;D

Man, those bring back memories.  I had some of the very first ones in the US when they came out, had a rack of over 100 of them making $300/day.  $225/ea they cost then lol  Volt modded them to be able to run at 400khash with some info that a member on here posted.  Took me forever to disassemble them one by one and bridge a couple contact points, then reassemble.  I think LTC diff was 9k or so and price was in the $30s, IIRC.

I'll see if I can find a pic of my rack...

Please do post the pics, that would be awesome to see. They were so badass when they first came out. Did you sell them all in the end?

YBcoin seems to be another good one for scrypt mining right now. Chinese based coin, volume is decent.

That whole rack only consumed like 1200W haha

Later I switched to using Rpis with Minera to control them.

Good times.... miss them.

Can you still remember this (https://www.youtube.com/watch?v=WbhYwk3I3Ds) guy?

:) I want two raspberry pi :)

let me see what I can do for you :)

I want a Raspberry Pi 3, the new one.

I have some coming mid-next week, will post a new thread once they arrive.  :)

cannot wait :)
