I'd probably use the power port to run a RasPi and just connect a case fan to a Molex from the PSU. But would prefer a 10-port over 7.

10 port hubs are just a 7 and a 4 port hub inside a box.

I'd like to make one that'd run off 20+ volt so a laptop brick could be used for full power at barrel currents, but that'd require a substantial redesign of the regulator. Maybe someday. Before that happens I'd probably build this guy a big brother like a 20-port that takes in power from 2x PCIe and quite possibly a couple screw terminals. In a bigger hub there'd be more room for options like that.

How difficult would it be to make the big brother stackable/modular? You could buy a controller/host for $20 and then as many individually powered 7/8 port lanes as desired.

edit: Can you make a "common slot" adapter? Just build stackable breakout board/usb hubs Cheesy

...ah I love ideas.

Since I'll be moving a lot of sticks first, both 2Pacs and Bitfury sticks, I'm also working on a USB hub (project "Aardwolf"). Here's the plan at present: 8 ports, seven active and one power only (fan maybe?). Takes in 12V through either a barrel or PCIe jack. There'll be a 3-position selector switch for 60W, 96W and 120+W input power, so if you're using a 12V5A brick, 12V8A brick, or high-current PCIe there'll be a safety limit how much power the hub will draw before kicking out. There'll also be a knob for adjusting available per-port output current between 0.5A and 3A. There'll be an internal monitor on each port and when a port exceeds the limit it'll be turned off (and the status LED will go red). A global reset button will re-enable all ports with one press. That's the plan so far anyway.

8 ports, seven with data and one power-only which can be used for a fan. I'll probably build it fairly open like the Eyeboot 49-port, where it's got a top and bottom panel but no solid sides so innards can get some airflow. The regulator circuit will need to push at most 24A, and I've already tested the circuit I'll be using to higher current draw than that. So yeah you should be able to run a high-power miner from each port. Oh yeah and each port has a big bypass capacitor to help out with load transients.

I like the idea of running pci-e, everything else is ran off it...would allow me to run the hub off a gpu rig.

Could you bundle this with a psu? Or have the option for it? Not everyone has power already available.

Traduire le google!

It's rude to ask questions and then act condescending about the answers because you've already formed a bias.

If you think that I'm being impolite...remember...I only reciprocate.
1127  Bitcoin / Hardware / Re: GekkoScience is now dabbling with 16nm ASICs for new designs on: February 26, 2017, 03:22:15 PM
I paid 30$ and 50$ for those superbpags and they shat the bed.

So somewhere around that...

How many ports, could you run a high power USB miner from each port without the hub melting? Built in fan for cooling?

Not at the moment. What kind of sticker were you looking for?

Just a simple BTC sticker, no words...the symbol only.

what do you want for the 970 shipped to the US?

Baikal is out of stock on quads... please dont tell me i have to buy 60 mini ones... Sad

they wouldnt sell 60 mins

limit 1 per person

I can't even get them to sell me 1 mini...wtf baikal?

Can you pm me price for about 50,000 sol/s on zcash worth of gear

50,000 would be about 200 7950's and any corresponding hardware/infrastructure.

50 * 700 = $35,000 give or take probably + shipping.

Not a bad price for $120 a day...you could retire on that in the right situation.

The hell you talking about? I've reached ROI on multiple miners that I purchased last year(think september/october).

It's all about making smart decisions vs making stupid ones...reinvest.

Compound interest is where the real money is made.

Quote from: kenny rogers
Every gambler knows
That the secret to survivin'
Is knowin' what to throw away
And knowin' what to keep
'Cause every hand's a winner
And every hand's a loser
And the best that you can hope for,
is to die in your sleep

Although people unwilling or incapable of running their own probability calculations won't necessarily be making a majority of smart decisions.

GPU's might be a better profit to electrical cost ratio, but they require a much higher initial buy in...and a little bit of technical skill to get the build off the ground. You can buy a "turnkey" asic for the same cost as a single decent GPU...and that isn't counting the additional hardware to make the GPU generate income.

As long as there are locations with free power...all mining devices have value.

draw up a schematic?

I'm sure you could contract one of the guys to make you a few.

edit: actually might be feasible with minor modifications to a breakoutboard

sure, blame it on your ISP

tout d'abord, je demande l'élimination de tous ceux qui n'ont pas respecté le règlement :
"(J'attends une réponse du style : 1.xxxxxxxxbtc)"

T'as déjà vu un problème de math où il est écrit une réponse du style ? En plus entre parenthèse.

Le sens de l'expression est une réponse qui ressemble à, non pas une réponde qui doit être nécessairement formaté comme cela.




Il y a deux sortes de personnes ...

L'un est le détail orienté, l'autre un fou.

Mettre les deux dans la même pièce, lequel est vous?

Are you looking for some sort of pci-e extender?

You could build one if you had to...it's simple tech.
