Nice deal. 
What speed are they running at? Are any overclocked?

In some good news my RedFury just got out of customs as well today.  I should have it to add to the others by saturday. Hopefully my hub does not have to wait so long as well.

In some good news my RedFury just got out of customs as well today.  I should have it to add to the others by saturday. Hopefully my hub does not have to wait so long as well.

I took  more photos.  I set all at the stock

freq 50  and it  pulls 44-45 watts.



 Set at a good over clock freq 54  and it pulls pulls 56 watts.

The hashrate jumps from 2.0 to 2.5 so 16 sticks go from 32gh to 40gh pulling only 56 watts at the plug pretty good. means it can pay for power at very high difficulty rate.



I did 16 at freq 54 on this hub



This hub does  only  7 of 10



I had as many as 18 on the stud hub running at 54  freq

[ManeBjorn]

That is just great. 
Once I get this I can sell my Anker 7 port hubs then.

Wow! philip, you must have a huge collection of everything that's available in the mining world!

[philipma1957]

i have lots of sticks, hubs, psu's gpu's ,but no big miners.  I had 4 cubes for about a week .  but I had a buyer for them when I got them.

I got into mining due to my ebay mac mini/pc upgrades.  i figured it would be a good fit .  has been nice so far.
I learned years ago that big ticket sales on ebay are very hard to do. so in mining I do smaller priced items . even if 1 out of 10 buyers on ebay robs me it is only for 1 or 2 usb sticks.

 I would have a hard time if a buyer robbed me of a knc jupiter .  I would most likely want revenge which leads to bad karma.  now if a buyer robs a usb stick or 2 I live with it. put them on a do not sell to list and move on.


These are the best hubs I have owned or tested as of today

 not the cheapest but the sturdiest so far. they seem to have the best power supply so far.

Yep that bitch is 20A clear……. and that's the constant current it can provide at 5v1
There is even room to slap in different PSU, but there is no need…

And yep I know they are not cheap…. if I could find a way to sell this stuff at $50USD there would be a massive market, that said , how many USB 2.0 hubs have we bought over the years… I have a massive box of them I use for spares….

I have a couple of other USB hub products in Metal cases I evaluated, but they fall down on the PSU, and by the time I costed a new case and integral PSU … they come out at about the same cost.


Since the Fury chips are highly dependent on the onboard regulators, the closer you can get to 5.X at the socket, the cleaner the regulation at the chip…

Once the supply at the socket comes down to 4.7-4.8 then the regulation goes on the buck convertor feeding the  Fury.

Seriously….. next time they used a buck convertor, they should have targeted one that could go as low 3-4v for it's supply rail…, very few devices give 5v at the USB socket…

This is why the 49 port hubs are dodgy…. you have the potential for 40-50A of current slopping around the tracks, ping ponging about at  MH bit rates…..
god only knows what all that inductance looks like on a double sided pcb…..
Plus the other issue is the 'sense wire' is too far away from the farthest USB connector when using the ATX PSU @5v

Weeeeeeeeee……

[ManeBjorn]

Lots of great info.
I was leery of the 49 ports hubs.  They looked great but other than the 333mh/s sticks I rarely saw them full with other types of USB ASIC's.

Don't get me wrong…
It is possible to get a 49 port 'hub tree' or even greater…. but not like that.

I have a very nice design for a 20,40,60,80 but the problem is the cost,  to get decent manufacturing prices I would have to run 500-1,000 pcs
(yep I could EASILY manufacture myself… but end up contaminating my residence with Lead/antinomy/mercury compounds)(queue red neck with toaster oven)

Just how many customers would I have…?
No one in their right mind is going to be using USB sticks for that sort of mine setup, which would basically leave setups for manufacturing.

Yesterday I was watching CCTVn ,
which is like a China undercover reporting… Shock HORROR… they found government approved Plastic water pipe manufacturers using Medical waste and contaminated plastics for municipal water supply pipe…
Y…A….W….N…  they do EXACTLY the same with all the food products they manufacture for the Export market… toasters,water kettles, clip together food containers (which incidentally is WHY I NEVER buy such products.. all my shit is glass or stainless)

Unfortunately what most people what these days is the cheapest shit possible, even if they have to buy and replace it 10 times….

If there is such a curse as reincarnation, I want to come back as the dumbest banjo strumming MOFO on the planet, because Ignorance truly is bliss.

I had seen a bunch of stuff about that and also the chemicals that are in the food and clothing over there are terrible too.
No need for safety I guess when you have a billion+ disposable people as their government treats them like.

The issue is they are exporting this crap………

Final happy post for today


Why you should not buy cheap shitty hubs with phone charger PSU from China…




Here we see a good 73 VAC between the usb connector & the metal body of my computer….

These make ideal 'inheritance' gift sets.. and also account for WHY you should not answer your phone whilst it is charging and then go in the refrigerator or lean on a radiator…

Incidentally these are in contravention LVD regulations for Europe, shame so many  'big brands' actually import this crap….

Unfortunately many of the Testhouse engineers are too inexperienced to understand this… and usually fail to correctly identify it on the testing reports.

So next time you touch your computer and 'feel' something…(yes yes Calm down) it may not be static……

Ive read through the thread but what are the dimensions for this hub ?

 I still have 1x 49 port hub  I use a 30 amp fuse not the stock 40 amp.  I run 38 antminers on it.  It works. but in no way is it the quality of this hub.
It could never run red fury or ice fury sticks well.   Does a good job with the ant miners. I rather have  3 of your hubs then the one 49 port hub , but the cost will hold me back.

Yes….
I know the issue is the shipping and the price.

I can work on the shipping by using surface delivery, and possibly switching steel to aluminum, but metal tooling is not cheap…

But I don't even think there would be enough interest in a kickstarter.

Well I am going to order at least one more.   Just waiting for coins to come in.

 I just took you up on the ebay second chance offer..  I need 110 volt usa. Paid via ebay-paypal.  this worked well as I am a bit short on BTC…

Thanks, voltage requested noted. Will PM you the tracking info once it is sent.

Hey Everyone.
I just got my hub today and I have to say it's great!
Just to test it quick I put in 3x 333Block Erupters, 1x RedFury and 1x BiFury.

All 5 popped right up and right up to full speed no waiting several mins to half and hour for top performance that was a pleasant surprise.
They all co-exist with no weirdness.
I am running MultiMiner and it had no issues detecting and using anything in the hub.
I am going to try a 5gh/s Jalapeno on it later this weekend as well as some more USB's.

Razorfishsl shipped this very fast, it actually showed up yesterday but snow kept my mail-lady from coming on the porch so I had to wait until today.
The packing was safe and secure and the unit arrived in perfect condition.
He also kept track of the shipping on his end and is very easy to work with.

Thanks so much I will be buying another in a few weeks as this unit ROCKS!!!!!!!!!!
