Great, please post pictures when you get a chance   

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.

Hi,

   any stock left for this cool hub?

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

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.

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

Nice weekend for you all

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  

Ordered!

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

Just got my 3 hubs in, Shiny!

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.

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

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

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.

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/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.

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



Payment received. Will get onto this ASAP 

Just ordered 1 hub with expedited shipping.

Thanks!

I state this:

Take your childish bullshit elsewhere.

 

Just going to copy the above:

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

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.

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:

There is another trick, that I outlined here, which is safer (does not involve messing with the registry):
