I also have 20 USB Block Eruptors on the way, but for now, this is what i have running at work (free power!)
There have been stories of people being sacked for using work computers to mine. Isn't your job worth more to you than some bitcoins?

Lurking since 2011...

If I'm allowed...
I have a somehow stupid question, but...
But since we all have old psu's, why can't I use one of these to control ASICs?
http://tctechcrunch2011.files.wordpress.com/2010/08/hub-03-620x465.jpg?w=620&h=465
According to my calculations, it would allow about 0.53 amps in 12 ports.
Besides being meant to be mounted in an inconvenient bay, what's the catch?

You would need USB extension cables because the Block Erupters are too wide.

Actuallu you could get 7 USB ASICs in that hub if they were staggered properly - i have a similar 8 port in the floppy drive bay that has 4 staggered and a fan blowing over them.

That's what I thought!!
Nice!!!! Smiley

i do GPU performance and scalability testing.... so it fits =]

is it stable with 10 BE's on 1 Anker Hub? What PSU do you use?

It is stable, and I used the stock power supply that came with the Anker USB hubs.

ATM, they are running for about 14 days now and going strong.

you're lucky. results seems variable. I have 8 BEs on a 10  ports Anker and I have frequent short I/O issues with 1,2,3 BEs where the green light get stuck.

Situation gets resolved by itself.

I'm waiting more BEs with I will test them with an Orico hub. Will see if it performs better.

I got a very long awaited package from the postman today - figured it was a good time to do some tidying.

Hashrate++
Mess--

Now everything is running from a PSU that I had purchased for my GPU bitcoin mining rigs 2 years ago. Saves 5 watts over running them from the original power bricks. Also adds active PFC.

nice! what is that thingy in the top-middle with the cage?

Is the USB Hub also beeing powered from the big PSU?

It looks like a (fairly old) variac, which is a variable voltage AC toroidal transformer. They're useful for controlling the power input into simple motors and static-type loads, like heaters. They're also good for blowing up electronics, because they can usually be turned up to give a voltage higher than their mains input.

Indeed it is, it's a 15A Superior Electric Powerstat, probably from the 1960s. It's a beast

And yep, the hub is powered by the ATX psu. I chopped the barrel plug off the original wall wart and soldered it to a 4 pin floppy drive power connector that I desoldered from a floppy drive in my junk pile. The hub has been modified to handle the higher current draw of the block erupters.

Its a bit embarassing (like my electronics-fu is now totally blown), but seeing as the chip on the left just found a block (and at a ridiculous 1 billion difficulty), its just so much of an unlikely event that I just had to share. BTW that's an EP4CE10E22C8N mining at 12 MHash/sec !!

solo-mining with something like that would've been quite, well,... stupid.

absolutely gorgeous miner, though. I love it.

absolutely gorgeous miner, though. I love it.

Hand crafted, with love, and quite a lot of swearing. Quite a conundrum, by rights it shouldn't work at all, breaks all the design rules for PCB layout (like what PCB, rats nest more like). Then it goes and repays me (or not, since its pool mining) by finding a block against all the odds. OK not solo, even I'm not that stupid, but within the first 500 shares of setting up a new account on BTCguild (it has been mining for about 6 months on other pools/accounts though, so not quite inifinitely improbable, hat tip to Trill).

Anyway, thanks for the compliment  Smiley
