And all the miners with free power and cooling. I'm surprised at how many there seem to be.

Everything's free in mom's basement.  Grin

Eventually, most people's momfare checks run out eventually. I really think these singles are game changers for building up mining clusters, curious what other people's thoughts are.

It's never as good as it seems and it is never as bad as it seems.

I really don't think that the GPUs 'flooding' into the market will have an effect on prices. We're only talking about a maximum of ~ 12,000 GH worth of GPUs.

Here's something else for yous guys. I'm too lazy to run the numbers. Here's the sales figures to give everyone a sense of scale.

It is the marginal demand & supply which drives prices.

At one point 5970s were going for $550.  Think about that.  A brand new 7970 with awseome gaming performance, lower heat, lower noise, and lower power consumption with a full warranty (and eye candy like better tesselation) for $550 or a used 5970 of unknown quality which is hotter, noisier, sucks more juice and has no warranty.

Which one do you think a gamer would pick?  No gamer was dropping $400, $500, $550 on 5970s.  Noob idiot miners were and hopefully they got burned hard.

A small change in supply or demand can have a larger change in price.  Hopefully we see a small rise in supply and a small fall in demand.  Not for me of course I am just looking out for those noob miners.  Don't want them getting burned paying too much for obsolete gear.  Smiley

Exactly.  That's why I'm waiting to buy a used BRL single for 50% off from some bored early adopter.  Cool

If that's not tech porn I don't know what is.

Are these boxes good for anything useful besides BTC mining?  I know the BFL web site says they're for crypto, but what specific applications would a single be good for besides BTC mining?

You sure about that, it would require a new bitstream.  Has BFL provided you details on how to reprogram your device?  Care to share?  BFL indicated (but hasn't been verified yet) that the JTAG would be useless for even ID the chip being used much less reprogramming the device.

May be some kind of MD5 bruteforcing, unlocking Nokia phones :)
The tasks that don't require high-speed data IO because there are no IO channels except for the USB.

Also since you don't know what exactly chip is used you can't develop a new bitstream/firmware.

No clue.  Sorry, I just assumed that it could be programmed to run any SHA256 calculations.  Didn't know there were additional restrictions on it beyond that.

Depends on the time of day. high 60s during most of the night and mid to upper 70s during the hottest part of the day.

I thought there was some encryption involved so you specifically CANNOT reprogram them?
Thus they are only single use?

There is a chance that BFL, as the key owner, can make new bitstreams, but not the user.

I do know there are brute force password crackers that use OpenCL-based GPUs.

I guess that's one thing you give up by going to a specialized device like BFL.  It's smaller and uses less power for the same hash rate as compared to a GPU but it can't be used for anything else.

Yes, sorry, that's what I meant.
I'm assuming only BFL can supply new bitstreams - so I guess if you wanted a new one you may have to pay them some amount to create it ...
