People spend thousands modifying their cars.  Cars which end up worth less than a standard car when they go to sell. 

People spend thousands buying bicycles to ride along the road, when a £90 Chinese bike would do exactly the same thing.

Hobbies are all, without exception, a way of 'wasting' money.  Because you go to work to earn money, so you can spend it.  That's the point.  If you didn't want to spend money, there'd be no point in going to work in the first place.

With 30GH/s going through BFGMiner to Eligius, it takes a few minutes to go from Diff 0 to Diff 8 - BFG complains about work underruns, and then difficulty seems to go up.  How it works I don't know.

I'll sort out a log for you tomorrow. 

Anker 10 ports are 3 hubs chained internally.

Also note some PCs can have a hub internally too, especially cheaper/older laptops.

2x ASICMiner Blades (13GHs each), Anker Hub with 10 ASICMiner Block Erupters, Corsair CX750 (runs the Blades, the Anker hub, the fan controller, the unpictured elcheapo 10 port hub), Intel NUC Celeron 847 mining controller machine running BFGMiner 3.2.1 on Windows 7 Enterprise x86



Close up of the Blade rig.  Blade is stuck to a Fractal Design "Moduvent" cover with 3M double sided tape, as are the 1300rpm Scythe GentleTyphoon 120mm and 800rpm Scythe 80mm fans.  Blades are powered off a single PCI-E 6-pin cable, which is made from a 6-pin PCI-E extension, chopped and soldered and fitted to the Blade's green Phoenix connector.  A standard 5mm LED with 680ohm resistor is fitted to the spare connections to make a power light.

Currently hashing at just shy of 30GH/s, and using about 320W at the wall, including the 5-port Netgear 10/100 switch, and the Compaq 1000VA online UPS' overhead.

They're OK if they're in open air, or even somewhere with a bit of air movement.  Mine are in a 10 port hub that's sitting beside the ATX PSU running my Blades.  The tiny bit of air movement from the fan in the PSU is enough to keep the temps down on the Erupters.

Just install from Git.  Even a total linux noob like me can install it and have it going in less than 2 minutes, even from command line.

CGMiner is terrible - that messing about with those damned WinUSB drivers, and even then it still works like crap.  BFGMiner has come a long, long way recently. 

32-bit apps just run on WoW64 (Windows on Windows).  They're not really running on Windows natively.

I don't know what the argument is anyway- Luke-Jr said it's 32-bit only due to the http server library that makes the Blade stuff work.  This is known, and has been for weeks.  The fact it works on Windows at all is fantastic work by Luke-Jr.

Correct.  And let BFG through the firewall if you've got that turned on, too.

Scratch that.  First time the Blade connects at each reboot, BFG quits.  It runs perfectly every time until the next reboot.

Blades aren't being restarted, just using the Switch Server function (the backup server are to a stratum_proxy running on my WHS.

It only works on 32-bit.  As in, not on 64-bit.   Why are you running it on 64-bit and expecting it to work? 

 

Code?    I added the --http-port 8330 command to the shortcut, and pointed the blades at the IP of the machine. As it says in the README.ASIC

Many people don't care, they're cheap enough that they're fun.  To me, and a lot of other folks it's just a pure giggle to run these things.

I used to spend money upgrading PCs and wasting electricity on the old distributed computing projects like RC5, OGR and SETI@Home.  Those made nothing back, it was just a race on a web page.

Now I spend money of mining widgets, but at least they make a bit of money back so I can buy more mining widgets.

Just cut the leads off the failing bricks, solder on a molex connector, and run them off a PC PSU.  You're wasting your time and money replacing bricks, they just aren't designed for 24/7 running at high load. 

I run all mine off the same PSU that powers my Blades.  Far more efficient too, I'm saving 20W by running my hubs off the ATX supply rather than the Anker hub supplies.  Plus I don't have to worry about a meltdown.

I wouldn't bother - you could pick up a "real" PC for less than a shitty tablet. 

That said, I don't see why it wouldn't work...

Got 3.2.1 running on Windows 7 Enterprise x86 last night.  As soon as the Blade connected to BFG, BFG just quit/disappeared.  Upon reopening BFG everything worked perfectly.  Connected the second Blade, and again BFG quits.  I've rebooted etc several times, and BFG is happy now. 

To me, it seems BFG quits on the very first instance on a Blade connecting to the HTTP port (perhaps something craps out creating the virtual device?). 

3.2.1 works OK on Linux, on the same machine (Intel NUC DCCP847DYE) with 4GB RAM and 30GB Kingston SSD).

I'm more interested in the novelty factor, rather than ROI.  I like tinkering with these things. 

I don't have one yet, there's a local group buy just starting, so maybe in a few weeks.  I'll of course try it if/when the miner appears.

Any news on BFG supporting the RedFury USB (2.5GH) miners, Luke?
