Just got 4 more antminers wired up, last 2 coming tomorrow for a total of 7 antminers and a 256GH Bitfury system. - roughly 1.65 TH

Of course, I wired up the entire crate with 2 antminers and 2 power supplies, got it in place, powered on - and only one PSU works .  With no good way of removing the bad PSU, I had to cut the power lines and route them to another PSU ziptied to the crate.

with some testing, found my solution:
shorting pins 31+34 turns on the system, with about 12.3V idle and 12.09V under a 400W load
shorting  pin 30 + 12V results in it jumping to about 12.8V (good for rcgroups, but not computer equipment)

no issues after about 15 minutes now

EDIT: MASSIVE FML - I assumed that because one PSU worked great the other would, and didnt fully test it before installing it at the very bottom of my crate build under 2 antminers and the working DPS-800GB. Had to cut all the power lines to the antminer (the antminer was also buried at the bottom of the build) and route them to a working supply

I could, I would have to check the shipping costs though, since shipping outside north america adds about $20-30 to my postage

Thats a bit too low sorry. if you are local to Toronto though i might be willing to negotiate for face-to-face; and you could see the quality of the coins

this should be in the S1 thread, not the U1 (usb sticks) thread

alternatively - you can do what i did and find a used network switch for <$20 (in my case, 48-ports for $10)

I have a bunch of these with me in Toronto, Ontario. Received directly from Casascius and immediately transferred to airtite capsules using nitrile gloves.

Looking for 2.25BTC (shipping with xpresspost included)

I thought I would get more interest at 2.5BTC, these are really beautiful coins!

Now 2.25BTC, shipping included - I would like to get a bit more liquidity that a stack of cold-storage coins affords me

TWO of mine shipped on the 25th :

would be nice to see some coupons for the orders that were shipped on or after the 25th, considering one of my 1.9BTC units came last week

 have just modified a DPS-800GB A power supply following the instructions;
pins 31 + 34
pins 30 + 12V

and testing without load i see a voltage of 12.8V - without the 30+12V pins shorted, voltage seemed much closer to 12.0V

I do NOT want >12.2V since this is for computer components rather than RC battery charging - Is the pin 30+12V connection designed to achieve a higher (12.8V) output, or will it drop to 12.0V once a load is applied? I followed instruction on the rcgroup forums

DPS-800GB A?

I just hand-soldered two of these to operate and maintain 12V (short pin 31->34 and 30->12V) but would love to see a simple attachment made for them to avoid some of the annoying close-quarters soldering on the side-by-side pins 30&31

I have a box of about 20 of these things that I plan to convert if the 2 test units work.

ps: any good method for load-testing 12V at 200W, 500W, or 700W?

If the ip/network settings are changed, the page will not continyue to auto-refresh -> just refresh the page/go back to the miner IP address and it will be up-to-date

MAKE SURE YOUR NETWORK (WAN) SETTINGS ARE:
ip: 192.168.X.XXX
subnet 255.255.255.0
router: 192.168.X.1
ipv4 broadcast: BLANK
dns: 8.8.8.8

the initial settings do not work on 95% of home networks without clearing the ipv4 broadcast and changing the dns

I think the coupons are given in cases where unexpected price changes occurred or other means of customer reward. IMO they dont have to give coupons, and I appreciate the times when they did

do it right and solder the connections. nothing worse than the connecting coming loose and either turning off the miner unexpectedly or shorting across to another pin and damaging equipment.

got 2 miners today (2 more coming tomorrow and waiting on a tracking number for the last 2) - both had thermal paste leaking from the screws - bad enough that about 8 chips between the 2 systems had paste all over the pins and clotting on the resistors.

A bit of 99% isopropyl and q-tips did the trick, but this seems to be a repeating issue that BITMAIN could improve on. Additionally, most of the PCB screws were about 1/4-turn to loose and 1 screw was about 2 turns loose.

However, both units run great - They squeeze into a stackable crate along with 2x835W server PSUs (I use two because drawing more than 600W from either of them creates a terrible screaming fan speed that is much less at <500W) and a 48-port network switch strapped to the top. 387.5MHz each for about 45C and 197GH

the averaging system can report strangely at times, espescially during the first 10-15 minutes. Ive seen 800GH in the 5s and 300GH average before at about 15min into use, but the pool was 200GH. it quickly/eventually settled to a correct average

I have an armory wallet with 1 BTC in it - 18MBduHLgWmQDMH5UZsrzYDtNnyDha85GT

I have no clue what the password is. I have 2 or 3 general passwords that ive tested numbers and capitals and spacings on and no luck. ive tried the obvious (password, mypassphrase, bitcoinwallet, etc) that might have been inspired at the time over a year ago.

Either i misspelled something or went with a string of characters which I cannot find - I'm giving 50/50 odds on which it could be.

How can i try to bruteforce an armory wallet with windows?

would a DPS-800GB A have the same method for powering on? Its the same style of connector.
ps: shorting pin 34 to the pin opposite it on the blade causes the fans to come on. I havent tested the voltage of it though since i lack a second set of hands/aligator clips

^exactly. that card prototype already will need 2-3 slots, and a radiator for it will probably be the only part of it that resembles the reference design.

honestly, they should scrap the design, make it a 4-chip standalone with some PCB  remodelling, and then watercool it in a 'normal' fashion. the PCI form-factor is clearly not working and could be the most terrible design in bitcoin history
