FutureBit Moonlander 2 USB Hubs Thread

[markcarline2]

Just found a supplier & ordered one of these, will report back when it turns up and it's running...

Sipolar A-400 , 10 ports 2.1A:

Just a quick note for Moonlander folk in UK and Europe - Am currently using this Plugable 7-port hub with x4 sticks, running fine so far: http://[Suspicious link removed]/2zkGMOu

Tried this Orico number: http://[Suspicious link removed]/2jdmoGn failed at more than two.

I have the same setup, you going to try 5x ? Also what speeds you running ?

I'm aiming for 6, 2 more sticks in the post. Running at 720 at the moment, stable, 4MHs per stick. Can obviously go higher, sink temps at mid 60's... Will post what happens with 6!

Ok. I have three more in the post on top of the four I have connected now.  I think it's just a matter of speed & amps that each one draws in order to get all seven running.  From my post on page two if this thread I think (in theory) we have 1.71a to play with per port...

"If you were to split all 7 ports up equally and assuming 100% efficiency you could in theory draw about 1.71A per port."

What we could do with is accurate amp / speed table for these.

UPDATE (and a WARNING!) :  I'm now running 5x moonlanders at clock=756 on the plugable 7 port usb 3 hub and my meter is showing power usage (for the hub alone) at 53.08w, i personally wouldn't like to try running 6x as this will exceed the rating of 60w (12v x 5a) so you're running the risk of overload, over heat / maybe fire etc.  I can confirm it's stable though  Time for a new hub...

Ha. I've got 6 up and running, but that adaptor is white hot. Didn't check the meter, but suspect you're right...<goes to check meter>/

edit - Yes, I've got c. 54w running 5 @ 768. Had 63.8w with 6, which is toooo much. Stolen the ebay idea of yours, looks good, and thanks...

Cool - let us know how you get on. I've got 10x of these on the way to (5x left / 5x right) to help with spacing..

I have got my modified (Frankenstein!) hub working with 3x Moonlanders (pics to follow)


Also been looking at Sipolar hubs to have a neater package with more Moonlanders. Is there any need/advantage for mining to have usb 3.0 instead of 2.0?

This makes my brain hurt.

$60 USB stick that makes $3/month.

$165 hub to run them.

20 Sticks = $1200

USB hub = $165

Monthly Profit $60

You are looking at a 2 year ROI if LTC price keeps rising a bunch.



Or For a similar investment you can buy an L3+ and ROI in 4 months


Why would anyone buy this junk?

 basicly zero power usage

I have some friends who have ordered a bunch who want to mine, but don't have a space where they can run a full sized industrial miner.

I have dead solid eyeboot Hub = $0
I am running a paid for pc that earns 1 dollar a day after power with its gpu.

Sticks  are 60-65.  I run 2 at  this pool

http://ltc.tbdice.org/users.htm


LWdix...uDYH8   Self   8.78M / 0.009%   8.5M / 0.242%   8.47M / 0.301%   8.5M / 0.293%   6.89M / 0.308%   18.66656


So I have a shot at a block of LTC and or a Block of Doge

At  A cost of 125 usd 

Meanwhile buy a L3+

Hot fairly loud  and it will break in under 2 years.

My stick will mine on  and one day they will pop a block.

I am fine with this.

Very little advantage to USB 3 for USB miners. They don't need the fast data transfer, but many USB3 hubs have extra power, so that's always nice.

$65 from directly from sipolar in China and it just got delivered, I'm on the east coast.  Seems like a great deal.

I ordered one over the weekend, for about 1/2 the price here:
https://www.aliexpress.com/snapshot/0.html?spm=a2g0s.9042647.0.0.8O4DWG&orderId=88528809006859&productId=32513481750

$45 USD, shipping is a crazy $20 USD, but still way cheap total.  Shipping will take a bit, but I think it is worth the wait.

Very very tempted to order this hub, anyone comment if it's any good ??

Cool, mine is still in the post, so how many moonlanders are you going to try?

If you take off the fans, you can run an extra row to the sipolar - just be sure to have some active cooling on them.

I'm running ten ML2 on Sipolar A400. Prefer Antminer L3+ but too loud to use at home or work. Don't they make mufflers for these things or something super quiet?

Will it run 10 at 954mhz?

I have mine set to hash around 4 Mh/s. I have two that may be duds, so until I get those resolved, I haven't tried pushing the frequencies higher. I'm around 744Mhz I think. I get really unstable results going any higher. Not saying you can't do it, but might require more tweaking than I have time for right now.

The highest freq I have got to work was 900Mhz but run at 876Mhz for best hash less HW errrors.
You will need lots of current for 10 @ 954Mhz maybe 150w source power supply feeding the hub.

Definitely. Each pair of mine on Anker hubs is pulling 30W at the wall. I currently have 6 sticks on 3 hubs and 4 more sticks pre ordered. It would be nice to have a single hub that can run them all at full speed, but it's not looking like such a hub exists.

I have Sipolar A400 with 10 ML2 & another Sipolar A400 with 10 2Pacs. They rate themselves at 12V 10A (120W), but you can't really push them to 120W (more like 100W). I've seen USB HUB that have separate 480W power supply. But if you're getting into that realm and cost, you might as well just buy an Antminer and muffle the sound with an ice chest rig or something.

eBay Sipolar hub has arrived, running 6 @768 without any fuss. Looks the part, very pleased. Thanks!

I got a TP-Link UH720 and Raspberry PI 3 (Raspian) and ran 4 Moonlander 2 on them. They run at standard core voltage @ 796 MHZ so about 4,5 MH per Moonlander. The power consumption for the hole setup is 50 watts.

That's a nice hub neochi, I like your setup. Can you share a pic the rig in action? How was setting up the RPi with the MLD2s?

[neochi]

Sure.

For not it is more or less not finished it will be looking like this until i have an idea how to fix.

The setup was quite easy. Raspian default installation. Update OS and the PI. Take the arm bfgminer and start running. Nothing special.
