Also it's possible that they know that 2500W is the maximum power available with normal wall sockets (in 220V-world) and decided that they'll try to fit their mining equipment into that limit somehow.

Here's a shoehorn. Helps fit things into other things.

Looks like a speculum.


If you're searching these lines for a point, you've probably missed it.  There was never anything there in the first place.

Goddamnit! Don't google shoehorn speculum on google images! WORSE than RandyFolds.

Received an email yesterday of a confirmation of my order of two BFL singles I put back on the Feb 25th.. even have a little PS saying Please excuse the late reply.  I wanted to email back but heck I would rather let them work then saying thanks for the update Smiley

I used to do business with China factories and Holidays always delayed orders getting done. I have been in their shoes to a point. In the meantime I wait like everyone else.. Hoping I get an email asking me if I want the extra Fan or not.. I dont need a extra fan Smiley Its cold enough in the Datacenter Smiley

Finally got a chance to get this hooked up.  I feel..... liberated.  I no longer need to have my PC on it's side, case open, with cards dangling out of it and a huge fan blowing at the whole mess.   I now have a tiny little box sat on my desk doing the work instead.    Just brilliant Smiley

Damn quiet in here now though Cheesy

Wait you got new hashing gear so you turned the old hashing gear off?  The hashes it produced are no longer valid?

Correct.  This isn't about me increasing my hashing power, it's about me reducing my power consumption.

Mission accomplished.

What's the size of the power socket on that thing?

The power-jack is 5.5 Outer-Diameter, 2.5 Inner-Diameter. Outer cylinder is ground and
inner core is +12V (Acceptable range: 10V to 14V).

How long is the outer cylinder (13mm, 14mm, 15mm?)


The jack is 12mm.


Regards,
BFL, I am having a hard time finding connectors to fit this spec. The closest I have found are Switchcraft 760's, which are 5.5 x 2.5mm, however the pin length is only 9.5 mm and the current rating is only 5 amps. By my calculations, the Single needs closer to 7 amps; will it be a major issue to use 5 amp rated plugs on this?

I don't know how much power is actually being lost due to PSU inefficiencies, so I don't know how much the actual DC power draw is. I have been using 75 watts for my estimations.

I have bought some of these http://search.digikey.com/scripts/DkSearch/dksus.dll?vendor=0&keywords=CP3-002BH-ND for BFL singles. They fit the spec, but are slightly longer than needed, should be ok, but I have not had the opportunity to test them yet.

Nice find! 8 amp rating too. Maybe if you combined it with my parts list above you could make a few $$ by making and selling adapters.

Something isn't right here.
No iron or washing machine in the US uses 2500W.
May be he is from some 220V-country and just used to such equipment ?
Most water kettles are 2300-2400W in 220V-world, same for steam irons, vacuum cleaners, cooking ovens, hair driers and so on

Also it's possible that they know that 2500W is the maximum power available with normal wall sockets (in 220V-world) and decided that they'll try to fit their mining equipment into that limit somehow.

So I just had to go and look:

  • My portable top of the line AC: 1240W
  • My run of the mill steam iron: 1200-1450W
  • My no-frills-but-cool-design water kettle: 1800W

I'm in 240V Europe, and these are plugged in at whatever outlet's the nearest.

So if I ordered a BFL Single unit today, when is the expected delivery?  I'm too lazy to read this entire thread.

I'm near the top of the list to receive a bitforce single 3rd generation with the ability of clock higher than the 1st and 2nd generation due to heat dissipation.

I should receive them early next week (just as the auction ends)
If not, I will start deducting its potential earnings from the winners price until it ships.
Isn't it better to wait for when you actually have the item?
Personally I won't bid for sure now, but would think about it if you already have the item.
