Certainly is a way to make modules available while as it is....

With the red herring add your own sockets to controller boards posts, there would be many modules and mangled controller boards up for auction.  Think of it, guy ruins a Jupiter hoping to overclock with extra modules that aren't even available, he makes a mess of it and abashedly auctions off 4 modules.

(go ahead, call me a fink)

I solder.  It is not a simple as it sounds.  The odds are higher that you'll make your controller board non-functional than succeed in adding sockets - unless you are an experienced technician with a lot of soldering time.  Get an old motherboard, remove a connector with .1" spacing between the pins even if it has many more pins than the socket  you wish to add to the controller board.  Try putting  one of those sockets into the motherboard.  You'll see it's more difficult than you expect.  Anyone who would tell a novice to try such a thing to a controller board is looking to reduce the net hashrate by killing your machine.

Find out what IP address it's using.  Use linux nmap or if you use Windows, there's a Windows version I suppose will give you the same data.

running nmap on one of my linux machines, the network address is 192.168.1.0 so the command is:

nmap 192.168.1.*

then it will output a scan report for every device on your network including some non-existent Windows devices.  The Merc gave me this:

Nmap scan report for 192.168.1.xyz (not really xyz)
Host is up (0.00013s latency).
Not shown: 998 closed ports
PORT     STATE     SERVICE
22/tcp open ssh
80/tcp open http
MAC Address: xx:xx:xx:xx:xx (Unknown)

It is reported as having an unknown manufacturer.

When my Merc has become difficult after a change of some kind, I disconnect the ribbon cables from the controller board and boot to access the BBB.

It helps to remember that once these outlive their profitability they have no use.  They can't be used for video games, they can't be used for distributed computing in the search for extraterrestrials nor can they be used with folding@home investigating protein folding.

If KnC just wants to exercise their machines and easily observe their NPS, since they know who bought Saturns and Mercurys, and since they know how many upgrade modules those buyers purchased, they can calculate how many unfilled positions there remain of the October orders and send out offers of upgrade modules only to those customers with *possible* open module positions and offer only enough to fill those boxes bringing them all up to Jupiters. (I have a Merc with two open positions.)

So, Asian New Years celebrations will be over when?

Pretty sure Oct. as there were no November Mercs or Saturns.

Perhaps something to do with the FPGA on the controller board interacting with the BBB.

Years back Ipads were available and way too expensive for my budget.  I watched closely for reviews of the tablets coming out of Asia.  There was a write up on the Cortex A8 that sounded very good.  Then Merrimobiles offered the Mid816 with the Cortex A8 at a reasonable price.  I still use it as my goto tablet tho I have one newer and three e-readers.  That Cortex A8 is the reason for choosing the BBB.

Okay, I was picturing the stuff we use to use up in NY within stairwells in commercial buildings.

Just looking out my back door at the power line to a 100 amp breaker box.  Two heavy insulated cables, L1 and L2, wrapped around insulated steel twisted support cabling, the support cabling wrapped around a very heavy insulator and going no further.  The two heavy insulated wires loop out and down to plasitc PVC to the breaker box.  In the ground at the base of the pole is a ground rod.

I think you ran steel conduit from a box to another box outside and grounded it well, sitting above ground it would have attracted the lightening.  Down here they cut the copper grounds that ran up the sides of roadside poles to the support cabling while leaving those copper grounds on poles down on property.  Your conduit offered a better ground than you incoming power support cable perhaps.

Reminds me of electronic proto lab engineers who went to do a show in Chicago where the unions wouldn't let extension cords be used.  The engineers came back with the lowest opinions of those electricians - talked about it for years.

Guess you brow beat your customers into paying lots and lots of money.  Shoddy?  What give any indication the work was shoddy?  Lightening will fry anything.

If the Neptunes are 220-240vac, he's okay.  If they run at 115vac they'll draw twice the current each.  If he has power into a room that via 12-3, it can be broken down into 115vac outlets some with L1 as hot and some as L2 as hot but the return on the 12-3 has a single neutral.  If Neptunes are to be run at 115vac (unlikely but possible) he could put 2 in series in a McGiver sort of arrangement.  That would keep the current down.  

Oh and one would not plan to run 12-3 or 10-3 to be split into 115vac outlets.  

And sorry Phoenix, I think two 115vac do not add up to 230vac.  Although only 2 phases come into a home they are generated in 3 phases I think.  They do not add up as 1 + 1 = 2.

I agree, bold.   Here we typically wire a 220v home dryer with 3 wire.  Three wire is a black, a red, a white, and an uninsulated ground conductor so 3 wire actually has 4 conductors.  In a 220v application like a dryer the current is flowing between the red and the black, not so much the neutral.  This means that if you split the 220 into two 115v lines, both returns will be on the single white.  While if you were to run two 12-2 (12 gauge white, black and an uninsulated ground) you'd have two white 12 gauge neutrals to return the current.  You should know that 12-2 only comes in black, white and uninsulated ground so even tho a strip vertical of circuit breakers in a service will alternate between L1 and L2, they will both have black hot leads.  The only time you'll see the red is for a 220vac application.  So, you can take a long 115vac extension cord and go around with that to other outlets and measure between the top right (hot) to top right and find some where hot to hot will measure 230vac while other hot to hot will measure 0v.

You might also see the red in a 14-3 when dual switches are used in a room when the overhead might be switched from either switch.

The original point being (before edit revisions) that if you need the 115vac to run the Neptune for some reason, you'd be able to split the L1 and L2 (from a 12-3), each to a neutral, giving 115vac on each but the neutral will be carrying current from both - a serious limitation.

Edit: It's been many years since I wired homes and I only have this mobile home to go by now but perhaps dryers 220v is simply the red and black (and ground) while not having a neutral but I don't ever recall seeing such a cable - like down here where they figure nobody with any smarts would live in a mobile home they sometimes use the neutral white for the red.

May I ask this is for how many of which miners?

Ah, I see.

I do use the ignore button freely.  Darned if I don't get tempted to unhide some.

Picture some guy who has me on ignore.  He goes to unhide that message ....

Looking at some other miners for sale in group purchases they had been priced for a btc break even at about 90 days, at the current rate and without increase, but has stretched out with recent increases.  Perhaps KnC is also seeing that and factoring that in with regard to possible Jupiter sales weighed against those sales degrading Neptune sales.  Jupiter sales will slow Neptune sales unless some Neptunes are fielded and producing.  Jupiter sales will effect sales of other miners.  Staying in the ball park relative to the competition with future Jupiter sales may be a choice they made.
