IN STOCK - OneStringMiner boards, up to 39GH/s last ITEMS: from US$15...FUN!!!

[BenTuras]

Little bit on the expensive side, but interesting how you are using less power. Will try to order one just to try it out.

Thanks for your interest.
Looking forward to your order.

OSM DIY2    2    60+    $465    €406    €336

465 bucks for 60 GH/S is VERY expensive. 700 will get you 200 GH/S.

I haven't adjusted the price of the DIY1 or DIY2 yet.
They come with a heat sink and our stock is very low on both heat sinks.
A second batch of heat sinks has been delayed, expected in two weeks.

And like I said before in this thread, it's impossible to compete on price for an OEM.
If you have your own ASIC design, you will always win on price.

[BenTuras]

After being asked whether or not the OneStringMiner boards run on p2pool, I have set up a 13 board tower and connected it to p2pool:



These are boards without a heat sink, so they do much better than the advertised 25+ GH/s.
But, we don't want to promise too much, so we keep on selling them as 25+ GH/s and you will probably get a faster board.

At first I was wondering about the high rejects, but this is normal for p2pool.
As far as I understand it, there is a short time span in which the pool requests to restart work and the miners haven't restarted yet.
If a share is found in that short time span, it is send to the pool and obviously the pool rejects it.

Thanks
And Paypal has a 7.5% surcharge on our price, so in the end it's just 1 pound less than the normal price.

Paypal is max 3.5% for the public, 2.9-1.4% on business fees? [Oh are you including ebay fees in that?]

It's even worse than that. Exchange rate, just selling stuff, posting an item, ....
Don't get me started about eBay, I think I am very modest with only 7.5%.

Do you have the 6 chip USB devices? Do you intend to get them in future?

We don't have the 6 chip USB devices.
And what's in the future ... is yet to be written

You are right on about having someone that answers questions . I really do appreciate great customer service when I receive it. I have a couple of ants, and they make me appreciate my one string boards. with the one string boards; my room isn't noticeably warmer, they make much less noise, and they don't drive my power bill up like the ants do.

I'll be adding to my one string collection soon.

Received mine, and I gotta say that these are awesome. Can you explain to me again the black magic used to get gen3 performance out of a gen2 chip which has been out for many months? Why hasn't everyone been running Bitfury chips on crazy-mega-power saving mode all along? Heck, even the board is simpler than most designs -- and thus, presumably, with fewer ways to fail.

I am somewhat floored by the gloriousness.

just needs to be scaled up and it would make for some mean, cheap 1TH machines.

Punin is starting to sell off Bitfury 6U 2.5TH/3kW miners now (overpriced) so they must be getting into gen2 heavily

And in the sales@btcguru.eu inbox another happy customer:
"I received my first DIY1, and it's kind of amazing -- thanks!! Now I'm ready for 2 more, please. I would like to pay with BTC."

[yslyung]

watching & really interested in this. awesome project. do you have anything more than 420gh? atm i'm running 9x290 cards and my power bill is insane here in korea. if i can get a good deal i will also help to promote your miner.

Ben the preceding is a snippet of a log from bfgminer run with --device-protocol-dump

it is plainly clear that the firmware shipped on the OSM boards is hard coded with a response the version command. if this is so and you have access to the source it would need modified to 15. if not could you request cscape recompile a fw specifically for the OSM boards with this modification.


Following this post, i will be trying to hack together a modification to bfgminer's Bifury driver to see if this fixes the poor performance.


the issue lies in the way bfgminer uses the FW response to VERSION to allocate and setup the queue. since it replies only 2 chip in the response the other 12 are left hungry as f*** and any values they find arent being logged since as far as BFG knows they dont exist


^_^ hoora stubbornness for digging

Thank you for investigating. I will forward your message. And love your phrase 'hungry as f***'
